DETAILED DESCRIPTION

[0042] Over time, a mattress can fall off or slide around on a foundation, such as an adjustable foundation. To overcome this concern, one or more zippers can be used to attach the mattress to the foundation. Accordingly, the mattress can be coupled (i.e., zippered) to the foundation. As a result, the mattress can remain in place on the foundation. The mattress can also be easily moved from or on the foundation by undoing the zipper. In embodiments of a bed system that has an adjustable foundation, the adjustable foundation can be used to selectively raise and lower a head and/or a foot of the mattress. In some embodiments, a mattress can be relatively heavy and/or flexible so as to naturally contour to the adjustable foundation's shape under force of gravity when one or more portions of the adjustable foundation are articulated. In other embodiments, a mattress can be relatively light weight and/or stiff so as to bend less under the force of gravity when one or more portions if the adjustable foundation are articulated. For either embodiment (and particularly for embodiments that have a mattress that is relatively light weight and/or stiff), a zipper attachment mechanism can be used to hold the mattress to the foundation during articulation such that the shape of the mattress can more closely follow the shape of the foundation.

[0043] FIG. 1 discloses a bed system 100 that includes a mattress 102 and a foundation 104. The mattress 102 can have a mattress cover 106 that includes a fabric 105, and the mattress cover 106 can enclose various internal parts (not shown) of the mattress 102, such as foam, springs, air chambers, and or other components suitable for the application. The fabric 105 of the cover 106 can be hypoallergenic or any other type of material intended to protect the mattress 102 from spills, stains, bacteria, and other allergens. In some embodiments, the fabric of the mattress cover 106 can be water-resistant. The fabric of the cover 106 can also allow for airflow and breathability. The cover 106 can be configured to fit over the entire mattress 102. In some embodiments, the cover 106 can be zippered around the mattress 102. In other embodiments, the cover 106 can be held in place around the mattress 102 by any other mechanism including but not limited to velcro, buttons, snaps, or other fasteners. The cover 106 can further have one or more seams 107 that can run along a length of the cover 106, for example from a head end to a foot end of the cover 106. The one or more seams 107 can also be positioned interior to a perimeter of the cover 106. Moreover, the one or more seams can be positioned around corners of the cover 106 such that the cover 106 is fitted around the mattress 102 having a particular height, length, and width. In some embodiments, the cover 106 can be an optional addition to the bed system 100. In other embodiments, the cover 106 can already come fitted to the mattress 102 in the bed system 100. In some embodiments, the cover 106 can be removable.

[0044] The mattress 102 defines a mattress top 108, a mattress bottom 110, and a mattress perimeter 112. In some embodiments, the seams 107 of the mattress 102 can be positioned on one, more, or all of the mattress top 108, the mattress bottom 110, and the mattress perimeter 112. For example, in some embodiments the mattress 102 can have some of the seams 107 around the mattress perimeter 112. Such seams 107 can connect one piece of fabric to another piece of fabric. In some embodiments, the seams 107 can be functional, aesthetic, or both. In some embodiments, the mattress 102 can have seams 107 on the mattress bottom 110. Such seams can be hidden from view when the mattress 102 is positioned on the foundation 104.

[0045] The foundation 104 has a foundation perimeter 120. The foundation 104 can include a platform 114 and legs 116. The platform 114 can define a foundation top 118. In some embodiments, the platform 114 can be made from a wood material, including but not limited to wood (such as medium density fiberboard or plywood), or other materials suitable for the application. The platform 114 can be covered in fabric, batting, or other materials.

[0046] The platform 114 of the foundation 104 can have one or more panels (e.g. a head panel, a foot panel, and one or more middle panels). In some embodiments, the foundation 104 can be an adjustable foundation configured to raise and lower one or more panels of the platform 114, which, in turn, raise or lower portions of the mattress 102. The adjustable foundation can be actuated via a controller and/or manually actuated by a user.

[0047] The mattress 102 can be connected (i.e., coupled) to the foundation 104 by a zipper 122. In some embodiments, the mattress 102 can be coupled to the foundation 104 by multiple zippers 122. In the embodiment of FIG. 1, the zipper 122 extends from a position proximate a head end of the mattress 102 to a position proximate a foot end of the mattress 102. Thus, the zipper 122 extends substantially a full length of the mattress 102. In some embodiments, the bed system 100 further includes a second zipper 122 (see FIG. 2B) that extends substantially a full length of the mattress 102 on the other side of the mattress 102, substantially parallel to the zipper 122. The zipper 122 includes zipper tapes 124A and 124B and zipper teeth 126A and 126B attached to the zipper tapes 124A and 124B, respectively. The zipper tape 124A can be attached to the mattress cover 106 at the mattress bottom 110 and the zipper tape 124B can be attached to the platform 114 of the foundation 104 at the foundation top 118. For example, the zipper tape 124A can be sewn to an underside of the cover 106 and the zipper tape 124B can be sewn to a fabric on a top of the foundation 104. In other embodiments, the zipper tape 124A can be attached to the mattress 102 by other suitable mechanisms. In addition or alternatively, the zipper 122 can be arranged at a head side and/or a foot side of the mattress 102. For example, the zipper 122 can extend substantially a full length of the head side and/or the foot side of the mattress 102.

[0048] In other embodiments, the zipper 122 extends at a length shorter than the full length of the mattress 102. Further, in other embodiments, the mattress 102 can be coupled to the foundation 104 by a single, continuous zipper.

[0049] The zipper 122 can be configured to attach the mattress 102 to the foundation 104 and to hold the mattress 102 in place on the foundation 104. In embodiments in which the foundation 104 is an adjustable foundation, the zipper 122 can retain the mattress 102 in place when the foundation 104 raises and/or lowers one or more panels of the platform 114, which further raises and/or lowers one or more portions of the mattress 102. Moreover, in such embodiments, the zipper 122 can extend substantially a full length, from a location near the head end of the mattress 102 to a location near the foot end of the mattress 102, across one or more articulation points of the mattress 102 and the foundation 104. Portions of the mattress 102 and the foundation 104 that bend during actuation can be considered articulation points. For example, in embodiments when the platform 114 of the foundation has multiple panels, a joint between two adjacent panels can be considered an articulation point. Therefore, the zipper 122 can be able to retain the mattress 102 to the foundation 104 when the foundation 104 is actuated and one or more portions of the mattress 102 are raised and/or lowered in response to one or more panels of the platform 114 being raised and/or lowered.

[0050] In some embodiments, the zipper 122 can be hidden from sight. As a result, additional covers and/or fabric may not be required to hide the zipper 122 from sight. The zipper 122 can be arranged and sewn into the seam 107 of the mattress 102 such that the zipper 122 is not visible. When the zipper 122 is sewn into the seam 107, the zipper 122 can take advantage of strength already existing in the seam 107. Therefore, the zipper 122 can be less likely to come undone or break when retaining the mattress 102 to the foundation 104. This can be especially advantageous when the foundation 104 is adjustable and one or more panels of the platform 114 and one or more portions of the mattress 102 are raised and/or lowered.

[0051] FIG. 2A is a top view of the foundation 104. As shown in FIG. 2A, the foundation 104 has the foundation platform 114 (which at least partially defines the foundation top 118), and the zippers 122 that include zipper tapes 124B and 124D. Each zipper tape 124B and 124D have zipper teeth 126B and 126D, respectively. The teeth 126B and 126D are configured to couple with the zipper teeth of the zipper tapes attached to the bottom of the mattress 102 (e.g., as shown in FIG. 2B) and therefore retain the mattress 102 to the foundation 104. The foundation 104 can further have a foundation cover 119 with one or more fabric portions at least partially covering the platform 114. Fabric portions of the foundation cover 119 can meet at one or more seams 142. The seams 142 can extend along an entire perimeter of the foundation top 118 (refer to FIG. 1, foundation perimeter 120). In some embodiments, the zipper tapes 124B and 124D can attach to the foundation top 118 at the seam 142, interior to the perimeter of the foundation 104. As a result, the zipper tapes 124B and 124D can take advantage of the strength of the existing seam 142 when the teeth 126B and 126D are coupled with the teeth of the zipper tapes attached to the mattress 102. In addition, the zipper 122 can be hidden from sight when the mattress 102 is coupled to the foundation 104. This is possible when the zipper tapes 124B and 124D are attached (i.e. sewn) interior to the perimeter of the foundation 104 and/or when the zipper tapes 124B and 124D are attached (i.e., sewn) into the seam 142.

[0052] In other embodiments, the seams 142 can extend along a portion of the perimeter of the foundation top 118. The zippers can attach to the foundation top 118 at the seams 142 as described above. In addition or alternatively, the zippers can extend along a portion of the foundation top 118 that has no seam.

[0053] In other embodiments, the zippers 122 need not be attached at seams. For example, in some embodiments the zippers 122 can be sewn to fabric at a location that does not include a seam. In other embodiments, the foundation cover 119 can be omitted and the zippers 122 can be attached to the foundation 104 via other suitable mechanisms, such as screws, bolts, rivets, or adhesive.

[0054] In some embodiments, the foundation 104 can define multiple passages 121A-B that extend through the foundation top 118. The passages 121A-B can be configured to allow passage of one or more hoses (not shown) through the foundation 104 and into the mattress 102. The passages 121A-B can be useful, for example, in embodiments where the mattress 102 is fluidically connected to an air source (not shown) in or under the foundation 104.

[0055] In some embodiments, the foundation 104 can be an adjustable foundation and the platform 114 can include multiple panels 128A-128D, including a head panel 128A, a middle panel 128B, a leg panel 128C, and a foot panel 128D. Each of the panels 128A-D can be moved when the adjustable foundation is actuated. When each of the panels 128A-D are moved, one or more portions of the mattress 102 attached to the foundation 104 by the zipper 122 can also be moved accordingly. For example, if the head panel 128A of the platform 114 is raised, the mattress 102 is raised as well at a head portion of the mattress 102, and the mattress 102 remains coupled to the foundation 104 by the zipper 122.

[0056] The foundation 104 can include an actuator (not shown) operably connected to each of the panels 128A-D of the platform 114 so as to actuate one or more of the panels 128A-D between raised and lowered positions in response to actuation by the actuator and a controller 150 operably connected to the actuator and configured to electronically drive the actuator to actuate one or more of the panels 128A-D between raised and lowered positions. In some embodiments, the one or more panels 128A-D can be actuated manually by the user with or without the controller 150. In other embodiments, the one or more panels 128A-D can be actuated automatically by the controller 150. The controller 150 can be configured to raise and/or lower one or more of the panels 128A-D from a predetermined minimum height to a predetermined maximum height. For example, using the controller 150, the user can raise the head panel 128A to a maximum height position while lowering the foot panel 128D to a minimum height position. Each of the panels 128A-D can be adjusted to a same height such that the user lays flat on top of the mattress 102.

[0057] FIG. 2B is a bottom view of the mattress 102. As shown in FIG. 2B, the mattress 102 includes the mattress bottom 110, the mattress cover 106, and the zippers 122. The zippers 122 further includes zipper tapes 124A and 124C which connect to zipper teeth 126A and 126C, respectively. The zipper teeth 126A and 126C are configured to couple with corresponding zipper teeth of the zipper tapes attached to the foundation 104 (shown in FIG. 2A) and therefore retain the mattress 102 to the foundation 104. In some embodiments, the zipper tapes 124A and 124C can attach to the mattress bottom 110 at one or more of the seams 107 interior to a perimeter of the mattress 102. As a result, the zipper tapes 124A and 124C can take advantage of the strength of the existing seam 107 when the teeth 126A and 126D are coupled with the teeth and the zipper tapes attached to the foundation 104. In addition, the zipper 122 can be hidden from sight when the mattress 102 is coupled to the foundation 104. This is possible when the zipper tapes 124A and 124C are attached (i.e. sewn) interior to the perimeter of the mattress 102, such as when the zipper tapes 124A and 124C are attached (i.e., sewn) into the seam 107.

[0058] FIG. 3 is a side view of the foundation 104 and the mattress 102 when the foundation 104 is an adjustable foundation. The foundation 104 can be actuated manually, by the user, and/or automatically by the controller, as previously described (refer to FIG. 2A). The mattress 102 is enclosed in the mattress cover 106 and the platform 114 of the foundation 104 is enclosed (i.e., covered) in the foundation cover 144, as previously described. The zipper 122 extends from a position near the head end of the mattress 102 to a position near the food end of the mattress 102 and couples and retains the mattress 102 to the platform 114 when the foundation 104 is actuated. As a result, the zipper 122 extends over one or more articulation points of the foundation 104 and the mattress 102. In some embodiments, a zipper tape of the zipper 122 is attached to a bottom of the cover 106 and another zipper tape of the zipper 122 is attached to a top of the foundation cover 144.

[0059] The mattress bottom 110 is raised when the head panel 128A of the platform 114 (refer to FIG. 2A) is actuated/raised by the controller 150. As a result, the head portion of the mattress 102 is also raised. As previously discussed, when the foundation 104 is an adjustable foundation and it is actuated, the mattress 102 remains coupled to the foundation 104 as one or more panels 128A-D of the platform 114 of the foundation 104 are raised and/or lowered, thereby raising and/or lowering the associated portions of the mattress 102.

[0060] In some embodiments, the zipper tape 124A can be attached directly to the mattress 102 (e.g. sewn to the mattress cover of the mattress 102) and the zipper tape 124B can be attached directly to the foundation 104 (e.g. to a cover of the foundation 104) without additional lengths of extension fabric in-between. In such embodiments, the zipper 122 can provide a relatively tight connection between the mattress and the foundation. For example, in embodiments where the zipper tapes 124A and 124B have a width of between about 1 and about 2 inches, then the zipper 122 can hold the mattress 102 to the foundation 104 with a gap of about 1 to about 2 inches. In other embodiments, the zipper tapes 124A and 124B can be narrower or wider for applications where tighter or looser connections are deemed desirable. In still other embodiments, one or more portions of fabric can be added as an extension where looser connections between the mattress 102 and the foundation 104 are deemed desirable.

[0061] In some embodiments, the zipper 122 can be spaced inward from a perimeter of the mattress 102 and the foundation 104 by an amount suitable to substantially conceal the zipper 122 from view and suitable to allow for sheets to be tucked in between the mattress 102 and the foundation 104. For example, the zipper 122 can be spaced inward from a perimeter of the mattress 102 and the foundation 104 by between about 2 and about 4 inches.

[0062] In some embodiments, the bed system 100 can include exactly two zippers 122 that connect the mattress 102 to the foundation 104. For example, a first zipper 122 can extend longitudinally along a left side of the bed system and a second zipper 122 can extend along a right side of the bed system.

[0063] In some embodiments, the bed system 100 can include exactly one zipper 122 that connects the mattress 102 to the foundation 104. For example, the zipper 122 can follow a full (or nearly full) loop whereby the zipper 122 extends along a top portion, a left side, a bottom portion, and a right side of the bed system 100. In one example, the zipper 122 can extend along a left side of the bed system 100, turn and extend along a foot side of the bed system 100, turn and extend along a right side of the bed system 100, and turn and extend along a top side of the bed system 100. In some embodiments with a single zipper 122 connecting the mattress 102 to the foundation 104, the zipper 122 can be positioned under the mattress 102 at a location inward of the perimeter of the mattress so as to have a gap between the perimeter of the mattress 102 and the zipper 122.

[0064] In some embodiments, the bed system 100 can have more than two zippers 122 that connect the mattress 102 to the foundation 104.

[0065] FIG. 4 is a schematic view of the bed system 100 when viewed from the head end. As shown in FIG. 4, the foundation 104 can include the legs 116 and the platform 114. In some embodiments, the foundation 104 is an adjustable foundation (refer to FIG. 3), wherein one or more panels 128A-D of the platform 114 can be adjusted to a raised or lowered height (refer to FIG. 2A). The platform 114 can be made from wood, such as medium density fiberboard or plywood, and covered in a fabric, as previously described throughout this disclosure.

[0066] The mattress 102 can be placed on top of the platform 114 of the foundation 104.

[0067] In some embodiments, the mattress 102 can include one or more air chambers 130 and one or more foam portions 132 covered in the mattress cover 106. The air chamber 130 can be an inflatable air chamber filled with air to provide support to one or more portions of the mattress 102. The amount of air in the air chamber can be adjusted by using an air controller having a pump or blower. As a result, fluid pressure in the air chamber 130 can be customized to change the firmness and/or support of the mattress 102. In some embodiments, the air chamber 130 can extend a full length of the mattress 102, from the head end to the foot end of the mattress 102. In other embodiments, the air chamber 130 can be placed in a particular portion of the mattress 102 (i.e., only at the head end and/or only at the foot end of the mattress 102). In yet other embodiments, multiple air chambers can be placed within the mattress 102 and each air chamber can be individually controlled/manipulated by the controller. In alternative embodiments, the air chamber 130 can be replaced with another type of mattress core suitable for the application.

[0068] The air chamber 130 can be surrounded on one or more sides by one or more foam members 134. For example, in some embodiments the foam members 134 can include a top foam member 134 and a number of side foam members 134 that combine to form an upside down foam tub 132 that can be placed on top of the air chamber 130 within the mattress 102. In other embodiments, the mattress 102 can have one or more foam members that are sized, shaped, and positioned differently than as illustrated in FIG. 4, or can have no foam members. In some embodiments, the mattress 102 can include one or more foam members 134 without the air chamber 130. For example, the air chamber 130 can be replaced with a mattress core that includes foam, springs, and/or other suitable materials.

[0069] The air chamber 130 can be formed of a layer of polymer material configured to substantially retain air and a layer of fabric configured to provide reinforcing strength. In some embodiments, such a combination of materials can be advantageous in making the air chamber 130 durable and substantially airtight. As a result, the combination of materials can substantially retain air within the air chamber 130 when weight is added on top of the mattress 102 and/or the mattress 102 is bent and/or articulated when the adjustable foundation is actuated.

[0070] Still referring to FIG. 4, a bottom of the air chamber 130 can be attached to the mattress cover 106 by a zipper 123. In some embodiments, the zipper 123 can extend substantially a full length of the air chamber 130 and/or the mattress 102. In other words, the zipper 123 can extend from a head end of the air chamber 130 to a foot end of the air chamber 130. In such embodiments, the zipper 123 can be sewn into (i.e., along) a seam of the air chamber 130. Therefore, the zipper 123 can take advantage of the existing strength in the seam of the air chamber 130 such that the zipper 123 does not become undone or break when the zipper 123 retains the air chamber 130 to the mattress 102. In some embodiments, the zipper 123 can be attached at one or more corners of the air chamber 130 such that the zipper 123 can take advantage of the strength of an existing seam along the one or more corners of the air chamber 130.

[0071] In addition to the zipper 123 connecting the air chamber 130 to the mattress cover 106, the zipper 122 can further connect the mattress cover 106 to the foundation 104. The zipper 122 can couple the mattress 102, via the cover 106, to the foundation 104. The zipper 123 can be arranged adjacent the zipper 122 (i.e., vertically aligned) such that both zippers 122 and 128 act together to form a relatively strong connection between the air chamber 130 and the foundation 104. Moreover, if the zippers 122 and 128 are aligned along seams of the air chamber 130, the mattress cover 106, and the foundation 104, the zippers 122 and 128 can take advantage of the existing strength from the seams. As a result, the connection between the mattress 102 and the foundation 104 can be relatively strong, especially where the foundation 104 is an adjustable foundation and the foundation 104 is actuated.

[0072] In some embodiments, the air chamber 130 can be omitted. For example, the mattress 102 can include a mattress core (that does not necessarily have any air chambers) inside the mattress cover 106. One or more zippers 128 can connect the mattress core to the mattress cover 106 and one or more zippers 122 can connect the mattress cover 106 to the foundation 104. Accordingly, a combination of one or more zippers 128 inside the mattress 102 and one or more zippers 122 outside of the mattress 102 can function to retain a mattress core (with our without an air chamber) in position on an adjustable foundation.

[0073] FIG. 5s a schematic elevation view of a portion of the bed system 100 in one embodiment, showing a portion of the zippers 122 and 128. The bed system 100 includes the foundation 104 and the mattress 102 (including the mattress cover 106 and the air chamber 130). In this example, the first zipper 122 connects (i.e., couples) the mattress cover 106 to the top 118 of the foundation 104 at the platform 114. The zipper tape 124A can connect the zipper teeth 126A to the mattress 102 (such as by being sewn along a seam, in some embodiments). The zipper tape 124B can connect the zipper teeth 126B to the top 118 of the foundation 104 at the platform 114 (such as by being sewn along a seam, in some embodiments). When the zipper 122 is zipped, the zipper teeth 126A can be connected to the zipper teeth 126B such that the zipper 122 can connect the mattress 102, via the mattress cover 106, to the top 118 of the foundation 104 at the platform 114. In other words, when zipper teeth 126A and zipper teeth 126B are coupled, the zipper 122 can securely attach the mattress 102 to the foundation 104.

[0074] In some embodiments, a second zipper, the zipper 123, can be used to retain the air chamber 130 (or another mattress core that does not necessarily include an air chamber). For example, the zipper 123 can connect an exterior underside (i.e., bottom) of the air chamber 130 to an interior portion of the mattress cover 106. The zipper 123 can include zipper tapes 136A and 136B that connect to corresponding zipper teeth 138A and 138B. The zipper tape 136A can connect the zipper teeth 138A to the mattress air chamber 130 (such as by being sewn to a bottom portion of the air chamber 130, in some embodiments). The zipper tape 136B can connect the zipper teeth 138B to the mattress cover 106 (such as by being sewn along a seam, in some embodiments). When the zipper 123 is zipped, the zipper teeth 138A can be connected to the zipper teeth 138B such that the zipper 123 can connect the air chamber 130 to the mattress cover 106.

[0075] This configuration of the zippers 122 and 128 can be beneficial in embodiments where the foundation 104 is an adjustable foundation. When the foundation 104 is actuated and one or more panels 128A-D comprising the platform 114 of the foundation 104 are raised and/or lowered, the one or more portions of the mattress 102 and one or more corresponding portions of the air chamber 130 move accordingly. For example, if the head panel 128A of the platform 114 is raised, then the corresponding portion of the mattress 102 is raised, as well as any part of the air chamber 130 that is located in that corresponding portion.

[0076] FIG. 6 is a schematic view of the bed system 200 when viewed from the head end. The bed system 200 is similar to the bed system 100 (shown in FIGS. 1-5) except that the bed system 200 has a different zipper configuration. The bed system 200 includes zippers 202 extending from the air chamber 130 to the platform 114 of the foundation 104. The zippers 202 can each include first and second zipper tapes 204 and 206, with the zipper tape 204 connected to the air chamber 130 and the zipper tape 206 connected to the foundation 104. The zipper tapes 204 and 206 can be zipped together in order to connect the air chamber 130 to the foundation 104 and hold the air chamber 130 in place on the foundation 104, such as during actuation of the foundation 104.

[0077] In some embodiments, the mattress cover 106 can define holes through which the zippers 202 extend between the air chamber 130 and the foundation 104. This can allow the zippers 202 to connect the air chamber 130 directly to the foundation 104 without additional intervening zippers. For example, the zipper 202 can extend a full distance between the air chamber 130 and the foundation 104 as opposed to using two zippers to span the same distance, such as shown in FIGS. 4 and 5.

[0078] FIG. 7A is a top view of one example of a foundation 700 having a zipper. The foundation 700 includes decks 702A and 702B. The foundation 700 can be king-sized. Each deck 702A and 702B can be separately controlled by one or more users of the bed system as described herein. In other implementations, the foundation 700 can be queen-sized, full sized, or twin/single sized. For example, a queen-sized bed system may have only one of the decks 702A-B or both the decks 702A-B.

[0079] Deck 702A has a head and upper back panel 708A, a lower-back panel (or base panel) 708B, an upper legs panel 708C, and a lower legs (or foot) panel 708D. The panels can be selectively adjusted by the user. Deck 702A defines a plurality of passages 703A that extend through the deck 702A. The passages 703A can allow for one or more air hoses, water hoses, electrical cables, and or other elongate connectors to extend from devices below the deck 702A to a mattress or other component positioned above the deck 702A. In some embodiments, the deck 702A can include a hose and cable guide structure 704A. The guide structure 704A can define the passages 703A that allows passage of the air hoses, water hoses, and/or electrical wiring from positions below the deck 702A to positions above the foundation 700. The deck 702A further includes a seam 714A joining two portions of fabric. A zipper 706A can be sewn into the seam 714A of the panels 708A and 708D. The zipper 706A can continue in a curved (e.g., U) shape around one or more sides of the panels 708A-D (e.g., a right side).

[0080] As depicted in FIG. 7A, the zipper 706A can be positioned around a perimeter of the deck 702A along more than one edge of the deck 702A. For example, as shown in FIG. 7A the zipper 706A can be positioned along three edges of the deck 702A. In other embodiments, the zipper 706A can be positioned along one, two, or four edges of the deck 702A. In some embodiments, the zipper 706A can be positioned inward of the perimeter of the deck 702A by a distance that is suitable for the application. In some embodiments, the zipper 706A can be positioned inward of the perimeter of the deck 702A by an amount that differs for different portions of the deck 702A. For example, in the illustrated embodiment the zipper 706A jogs out around the cable guide structure 704A and the passages 703A, yet is positioned further inward along other portions of the deck 702A. As a result, the zipper 706A can be placed at a first distance from the perimeter of the deck 702A at some locations and at a second distance from the perimeter of the deck 702A where the cable guide structure 704A is located. The first and second distances can be different to accommodate for the zipper 706A jogging out around the cable guide structure 704A so as to contain and conceal any hoses and cables. As mentioned, the zipper 706A can be curved to transition between the first and second distances. The curves in the zipper 706A can make it easier to zip the foundation 700 to the mattress. The curves can also be beneficial to increase strength and durability of the connection afforded by the zipper 706A. Additionally, the curve can be beneficial to protect the cable guide structure 704A and components therein.

[0081] An unsewn zipper tail 712A can be attached to the zipper 706A. The zipper tail 712A can protrude from the top of the foundation 700 such that a user can easily grab the tail 712A. The zipper tail 712A can make it easier for the user to bring together the portion of the zipper 706A that is attached to the foundation 700 with a portion of the zipper 706A that is attached to a bottom of a mattress. As a result, the user can easily and quickly zip the foundation 700 and mattress together. The tail 712A can reduce the likelihood that the user would have to move or lift the mattress from the foundation 700 to locate the zipper 706A and try to align portions of the zipper 706A.

[0082] Similarly, the deck 702B has a head and upper back panel 710A, a mid-back panel (or base panel) 710B, an upper legs panel 710C, and a lower legs (or foot) panel 710D. The panels can be selectively adjusted by the user. Deck 702B defines a plurality of passages 703B that extend through the deck 702B. The passages 703B can allow for one or more air hoses, water hoses, electrical cables, and or other elongate connectors to extend from devices below the deck 702B to a mattress or other component positioned above the deck 702B. In some embodiments, the deck 702B can include a hose and cable guide structure 704B. The cable guide structure 704B can define the passages 703B that allows passage of the air hoses, water hoses, and/or electrical wiring from positions below the deck 702B to positions above the foundation 700. The deck 702B further includes a seam 714B joining two portions of fabric. A zipper 706B can be sewn into the seam 714B of the panels 710A and 710D. The zipper 706B can continue in a curved (e.g., U) shape around one or more side of the panels 710A-D (e.g., a left side). As depicted in FIG. 7A, the zipper 706B jogs out around the cable guide structure 704B. An unsewn zipper tail 712B can be attached to the zipper 706B. The zipper tail 712B can protrude from the top of the foundation 700 such that a user can easily grab it. The user can use the zipper tail 712B to attach the zipper 706B to a zipper on a bottom of a mattress and zip the foundation and mattress together.

[0083] As depicted, zippers 706A and 706B can cover 3 edges of the respective decks 702A and 702B. The zippers 706A-B are advantageous so that a mattress contours better to the foundation 700, especially when the foundation 700 is adjusted. The zippers 706A-B also can more securely retain a large mattress (e.g., king or queen size) to the foundation 700. Furthermore, the zippers 706A-B can reduce stress concentration along the seams of the foundation and mattress and prevent breakage or ripping of any of the materials used to secure the zippers 706A-B to the foundation and mattress.

[0084] Along an outer edge, the zippers 706A and 706B can jog around the respective cable guide structures 704A and 704B. As previously mentioned, the distance from the zippers 706A-B to the perimeter of the foundation 700 around the cable guide structures 704A-B can be less than the distance from the zippers 706A-B to the perimeter of the foundation 700 around the head and foot ends of the foundation 700 (e.g., panels 708A, 708D, 710A, and 710D). Jogging the zippers 706A-B around outer perimeters of the cable guide structures 704A-B is advantageous to reduce stress from retaining the mattress to the foundation, especially where the foundation is adjustable.

[0085] When the zippers 706A-B jog around the cable guide structures 704A-B, the zippers 706A-B can be closer to a perimeter of the foundation 700. The zippers 706A-B can be farther away from the perimeter of the foundation 700 along head and foot ends of the foundation 700. As depicted, the zippers 706A-B can also be positioned farther away from the perimeter of the foundation along portions of the sides of the foundation 700 where the housing components 704A-B are not located. This configuration can be advantageous so that the user can tuck sheets around and under the mattress with less obstruction from the zipper attachment. Moreover, attaching the zippers 706A-B farther away from the perimeter of the foundation 700 along the head and foot ends can be advantageous to make up for the reduced amount of space available for tucking sheets around the cable guide structures 704A-B.

[0086] In some examples, the zippers 706A-B can be attached 5 inches inward from the perimeter of the foundation 700 along the head and foot ends as well as portions of the sides of the foundation 700 (e.g., portions where the zippers 706A-B do not jog around the cable guide structures 704A-B). In other examples, the zippers 706A-B can be attached at different distances from the perimeter of the foundation 700 depending on the location along the perimeter of the foundation 700. For example, the zipper 706A can be attached closer to the perimeter of the foundation 700 at or near the head end but farther away from the perimeter of the foundation 700 at or near the foot end.

[0087] In some examples, the example foundation 700 can be queen-sized. The queen-sized foundation can have one set of panels (e.g., panels 708A-D). In some embodiments where the queen-sized foundation has one set of panels, two zippers 706A and 706B can be used to securely attach a queen-sized mattress to the foundation. For example, one zipper (e.g. zipper 706A) can curve around two or more edges of the foundation 700 and another zipper (e.g. zipper 706B) can curve around two or more edges of the foundation 700 (including different edges and/or the same edges as those along which the zipper 706A is positioned). In some embodiments where the queen-sized foundation has one set of panels, one zipper (e.g., zipper 706A) can be used to curve around three edges of the foundation 700. In other implementations, the queen-sized foundation can have one zipper (e.g., zipper 706A) that curves around four edges of the foundation. The zipper can be positioned at an equal distance around the perimeter of the foundation 700 or at varying distances around the perimeter of the foundation 700, as described herein.

[0088] FIG. 7B is a bottom view of one example of a mattress 720 having a zipper. The mattress 720 can be positioned on top of the foundation 700 as depicted in FIG. 7A. The mattress 720 can be king-sized. In other implementations, the mattress 720 can be queen-sized, full sized, or twin/single sized.

[0089] The mattress 720 can have a bottom deck 722. The bottom deck 722 can define a plurality of passages 725 that extend through the deck bottom deck 722. The passages 725 can allow for one or more air hoses, water hoses, electrical cables, and or other elongate connectors to extend from devices below the bottom deck 722, such as the foundation 700 to one or more components of the mattress 720. In some embodiments, the bottom deck 722 can include a hose and cable guide structure(s) 726A-B. The guide structure 726A-B can define the passages 725 that allows passage of the air hoses, water hoses, and/or electrical wiring from positions below the bottom deck 722. The bottom deck 722 further includes a seam 728 joining two portions of fabric. Zippers 724A and 724B can be sewn into the seam 728. The zippers 724A and 724B can continue in a curved (e.g., U) shape around one or more sides of the mattress 720. The seam 728 can be aligned with the seams 714A and 714B of the foundation 700, as depicted in FIG. 7A. As a result, when sewn into the seams 728, 714A, and 714B, respectively, the zippers 724A, 724B, 706A, and 706B can be aligned with each other when the mattress 720 is positioned on top of the foundation 700.

[0090] As depicted in FIG. 7B, the zippers 724A and 724B can be positioned around a perimeter of the bottom deck 722 along more than one edge of the deck 722. For example, as shown in FIG. 7B the zippers 724A and 724B can be positioned along three edges of the deck 722. In other embodiments, the zippers 724A and 724B can be positioned along one, two, or four edges of the deck 722. In some embodiments, the zippers 724A and 724B can be positioned inward of the perimeter of the deck 722 by a distance that is suitable for the application. In some embodiments, the zippers 724A and 724B can be positioned inward of the perimeter of the deck 722 by an amount that differs for different portions of the deck 722. For example, in the illustrated embodiment the zippers 724A and 724B jog out around the cable guide structures 726A and 726B and the passages 725, yet is positioned further inward along other portions of the deck 722. As a result, the zippers 724A and 724B can be placed at a first distance from the perimeter of the deck 722 at some locations and at a second distance from the perimeter of the deck 722 where the cable guide structures 726A and 726B are located. The first and second distances can be different to accommodate for the zippers 724A and 724B jogging out around the cable guide structures 726A and 726B so as to contain and conceal any hoses and cables. As mentioned, the zippers 724A and 724B can be curved to transition between the first and second distances. The curves in the zippers 724A and 724B can make it easier to zip the mattress 720 to the foundation 700, as depicted in FIG. 7A. The curves can also be beneficial to increase strength and durability of the connection afforded by the zippers 724A and 724B. Additionally, the curve can be beneficial to protect the cable guide structures 726A and 726B and components therein. As depicted, the zippers 724A and 724B can also be positioned farther away from the perimeter of the mattress 720 along portions of the sides of the mattress 720 where the cable guide structures 726A and 726B are not located. This configuration can be advantageous so that the user can tuck sheets around and under the mattress with less obstruction from the zipper attachment. Moreover, attaching the zippers 724A and 724B farther away from the perimeter of the mattress 720 along head and foot ends can be advantageous to make up for the reduced amount of space available for tucking sheets around the cable guide structures 726A and 726B.

[0091] In some examples, the zippers 724A and 724B can be attached 5 inches inward from the perimeter of the mattress 720 along the head and foot ends as well as portions of sides of the mattress 720 (e.g., portions where the zippers 724A and 724B do not jog around the cable guide structures 726A and 726B). In other examples, the zippers 724A and 724B can be attached at different distances from the perimeter of the mattress 720 depending on the location along the perimeter of the mattress 720. For example, the zipper 724A can be attached closer to the perimeter of the mattress 720 at or near the head end but farther away from the perimeter of the mattress 720 at or near the foot end.

[0092] The zippers 724A and 724B are advantageous so that the mattress 720 contours better to the foundation 700, especially when the foundation 700 is adjusted. The zippers 724A and 724B also can more securely retain a large mattress (e.g., king or queen size) to the foundation 700. Furthermore, the zippers 724A and 724B can reduce stress concentration along the seams of the foundation 700 and mattress 720 and prevent breakage or ripping of any of the materials used to secure the zippers 724A and 724B to the mattress 720 and foundation 700.

[0093] Unsewn zipper tails 728A and 728B can be attached to the respective zippers 724A and 724B. The zipper tails 728A and 728B can protrude from the bottom of the mattress 720 such that a user can easily grab the tails 728A and 728B. The zipper tails 728A and 728B can make it easier for the user to bring together the portion of the zippers 724A and 724B that are attached to the mattress 720 with a portion of the zippers 706A and 706B that are attached to a the top of the foundation 700, as depicted in FIG. 7A. As a result, the user can easily and quickly zip the mattress 720 and the foundation 700 together. The tails 728A and 728B can reduce the likelihood that the user would have to move or lift the mattress 720 from the foundation 700 to locate any of the zippers 724A, 724B, 706A, or 706B and try to align portions of these zippers.

[0094] In some examples, the example mattress 720 can be queen-sized. Two zippers 724A and 724B can be used to securely attach the queen-sized mattress 720 to a foundation. For example, one zipper (e.g. zipper 724A) can curve around two or more edges of the mattress 720 and another zipper (e.g. zipper 724B) can curve around two or more edges of the mattress 720 (including different edges and/or the same edges as those along which the zipper 724A is positioned). In some embodiments, one zipper (e.g., zipper 724A) can be used to curve around three edges of the mattress 720. In other implementations, the queen-sized mattress can have one zipper (e.g., zipper 724A) that curves around four edges of the mattress 720. The zipper can be positioned at an equal distance around the perimeter of the mattress 720 or at varying distances around the perimeter of the mattress 720, as described herein.

[0095] FIG. 8A is another top view of another example of a foundation 800 having a zipper. The foundation 800 includes decks 802A and 802B. The foundation 800 can be king-sized. Each deck 802A and 802B can be separately controlled by one or more users of the bed system described herein. In other implementations, the foundation 800 can be queen-sized. In some embodiment, the queen-sized bed system can have only one set of the decks 802A-B. Accordingly, the foundation 800 can include left and right decks 802A and 802B (with or without multiple panels each) or can have a joined left and right deck (with or without multiple panels).

[0096] The deck 802A has panels 808A-D. The deck 802B has panels 810A-D. Panels 808A-D and 810A-D can each be selectively adjusted by one or more users. In the foundation 800, zipper 806A extends along 3 edges of the deck 802A. The zipper 806A can be attached at an equal distance from a perimeter of the foundation 800 (e.g., 5 inches all around the perimeter). Similarly, zipper 806B extends along 3 edges of the panel 802B at an equal distance from the perimeter of the foundation 800. For example, the zippers 806A-B can be positioned 5 inches from a perimeter of the head, foot, and side ends of the foundation 800. In comparison to the foundation 700 in FIG. 7A, the foundation 800 does not have cable guide structure and therefore the zippers 806A-B can be uniformly distanced from the perimeter of the foundation 800. Using straight-lined zippers 806A-B can be cost efficient and stronger in retaining a larger mattress to a larger foundation base.

[0097] The zippers 806A-B can be sewn into a seam of the decks 802A and 802B. The zippers 806A-B can also be sewn into a common seam or any other portion of the decks 802A and 802B.

[0098] FIG. 8B is another bottom view of another example mattress 820 having a zipper. The mattress 820 can be positioned on top of the foundation 800 as depicted and described in reference to FIG. 8B. The mattress 820 includes a bottom deck 822. The mattress 820 can be king-sized. In other implementations, the mattress 820 can be queen-sized.

[0099] For the mattress 820, zippers 824A and 824B can extend along 1, 2, 3, or 4 edges of the deck 822. The zippers 824A and 824B can be attached at an equal distance from a perimeter of the mattress 820 (e.g., 5 inches all around the perimeter). For example, the zippers 824A and 824B can be positioned 5 inches from a perimeter of head, foot, and side ends of the mattress 820. In comparison to the mattress 720 in FIG. 7B, the mattress 820 does not have cable guide structures and therefore the zippers 824A and 824B can be uniformly distanced from the perimeter of the mattress 820. Using straight-lined zippers 824A and 824B can be cost efficient and stronger in retaining a larger mattress to a larger foundation base.

[0100] The zippers 824A and 824B can be sewn into a seam of the deck 822. The zippers 824A and 824B can also be sewn into a common seam or any other portion of the deck 822 so as to align the zippers 824A and 824B of the mattress 820 with zippers 806A and 806B of the foundation 800, as depicted in FIG. 8A.

[0101] FIG. 9 is a view of a zipper tail 902 as implemented in an embodiment of the bed system of FIG. 1. As depicted, a zipper 900 can be attached to a foundation 901. In some implementations, the zipper 900 can also be attached to a mattress along a seam. The zipper 900 can have the zipper tail 902. A first portion of the zipper 900 can be connected to the foundation 900 along seam 904. The zipper tail 902 can be a second portion of the zipper 900 that hangs from the first portion of the zipper 900. The zipper tail 902 may not be connected to the foundation 901 or the mattress, except by the first portion. In some implementations, the zipper tail 902 can be 3 inches long.

[0102] The zipper tail 902 can protrude from between an underside of the mattress and a top of the foundation 901. As a result, a user can easily grab the zipper tail 902 and use it to align teeth of the zipper 900 when the mattress is positioned on the foundation 901. The user can then more easily zip the zipper 900 around the mattress and foundation 901. The user does not have to bend over to search for the zipper 900. The user also does not have to move or re-adjust the mattress on top of the foundation 901 in order to find the zipper 900. This is because the zipper tail 902 can act as a lead or guidance for easier and more seamless zippering of the zipper 900 when the mattress is positioned on top of the foundation 901.

[0103] The zipper tail 902 can be tucked under the mattress when the mattress is positioned on and connected to the foundation 901 by the zipper 900. Therefore, the zipper tail 902 can be hidden from view but still easily grabbed to attach the zipper 900.

[0104] FIG. 10A is a view of a zipper attachment as implemented in an embodiment of a bed system 1000 of FIG. 1. The bed system 1000 depicted can include a foundation 1002 (e.g., base) and a mattress 1006 connected by a zipper 1010. The zipper 1010 can be indirectly connected to the foundation 1002 via an elongate structure 1004 that is connected to the foundation 1002 via snaps 1012A-1012N or other suitable fasteners. An elongate structure 1008 can also be snapped onto the mattress 1006 with snaps 1014A-1014N or other suitable fasteners. First and second zipper tapes of the zipper 1010 can be sewn into or otherwise attached to each of the elongate structures 1004 and 1008. In some embodiments, connecting the first and second zipper tapes of the zipper 1010 to the elongate structures 1004 and 1008 can provide for installation of the zipper 1010 that can be quicker, easier, and/or more serviceable as compared to sewing the first and second zipper tapes of the zipper 1010 directly to the foundation 1002 and the mattress 1006.

[0105] For example, if a portion of the zipper 1010 breaks or needs to be reinstalled for some reason, either one of the elongate structures 1004 and 1008 can be detached from the foundation 1002 or the mattress 1006, respectively. Therefore, the entire mattress 1006 or the foundation 1002 does not need to be replaced when a portion of the zipper 1010 breaks or needs to be replaced if instead the elongate structure 1004 or 1008 can be replaced instead. This can provide for easier and less expensive repair of the zipper 1010.

[0106] In some implementations, only the mattress 1006 can have the elongate structure 1008 snapped to it by the fasteners 1014A-N. A zipper tape of the zipper 1010 can then be sewn/attached directly to the foundation 1002. It can be advantageous to have the elongate structure 1008 only on the mattress 1006 because replacing the mattress 1006 when there is damage to the zipper 1010 can be costly. Moreover, tension caused to the zipper 1010 by adjustment of the mattress 1006 on an adjustable foundation can make damage to the zipper 1010 more likely when the zipper 1010 is attached directly to the mattress 1006. As a result, it can be more advantageous to have the elongate structure 1008 configuration attached to the mattress 1006 with the zipper 1010 attached to the elongate structure 1008 rather than directly to the mattress 1006.

[0107] In yet other implementations, only the foundation 1002 can have the elongate structure 1004 snapped to it by the fasteners 1012A-N. A zipper tape of the zipper 1010 can then be sewn/attached directly to the mattress 1006. It can be advantageous to have the elongate structure 1004 only on the foundation 1002 because replacing the foundation 1002 when there is damage to the zipper 1010 can be costly. Moreover, tension caused to the zipper 1010 by adjustment of the mattress 1006 on an adjustable foundation can make damage to the zipper 1010 more likely when the zipper 1010 is attached directly to the foundation 1002. As a result, it can be more advantageous to have the elongate structure 1004 configuration attached to the foundation 1002 with the zipper 1010 attached to the elongate structure 1004 rather than directly to the foundation 1002.

[0108] In some embodiments, the fasteners 1012A-N and 1014A-N depicted in FIG. 10A can be snaps. In other examples, the fasteners 1012A-N and 1014A-N can be buttons, bolts, screws, or other suitable fasteners.

[0109] FIG. 10B is a view of a zipper attachment as implemented in a foundation 1002 of FIG. 10A. As depicted, the elongate structure 1004, as described in reference to FIG. 10A can have a first straight section 1020 that extends along a head end of the foundation 1002, a second straight section 1024 that extends along one of first and second sides of the foundation 1002, and a third straight section 1028 that extends along a foot end of the foundation 1002. The elongate structure 1004 can also have first and second curved sections 1022 and 1026 that connect the second straight section 1024 to the first straight section 1020 and the third straight section 1028.

[0110] In some embodiments, the elongate structures 1004 and 1008, as depicted and described in reference to FIGS. 10A-B, can be rigid or semi-rigid polymer structures. For example, the elongate structures 1004 and 1008 can be extruded polymer structures that are more rigid than the first and second zipper tapes of the zipper 1010. The elongate structures 1004 and 1008 can be spaced inward from a perimeter of the foundation 1002, as described throughout this disclosure (e.g., refer to FIG. 7A). In embodiments where the foundation 1002 is an adjustable foundation for raising and lowering the mattress 1006, the elongate structures 1004 and 1008 can connect to more than one of adjustable foundation panels and/or portions of the mattress 1006.

[0111] FIG. 11 is a schematic view of a zipper 1105 as implemented in an embodiment of a bed system 1100 as described herein. The bed system 1100 includes a mattress 1102 and a foundation 1104. The zipper 1105 can have first and second zipper tapes 1106A-B. The first zipper tape 1106A can have first zipper teeth 1107A and a first end connector 1108A. The first end connector 1108A can have a first magnetic portion 1110A. The first zipper tape 1106A can be attached to a bottom of the mattress 1102. The second zipper tape 1106B can have second zipper teeth 1107B and a second end connector 1108B. The second end connector 1108B can have a second magnetic portion 1110B. The second zipper tape 1106B can be attached to a top of the foundation 1104.

[0112] The first magnetic portion 1110A can engage and connect to the second magnetic portion 1110B. The first and second magnetic portions 1110A-B can pull the first and second end connectors 1108A-B together when the mattress 1102 is positioned on the foundation 1104 with the first end connector 1108A positioned next to the second end connector 1108B. As a result of placing the first and second end connectors 1108A-B near each other, the first and second magnetic portions 1110A-B can snap together (e.g., engage with each other) such that the first and second zipper tapes 1106A-B are aligned. The user can then easily zip the zipper 1105 around the mattress 1102 and foundation 1104. This can be advantageous by making it easier for the user to align the first and second zipper tapes 1106A-B when placing the mattress 1102 on the foundation 1104 with less need to manually move the mattress for alignment. Therefore, the user can more easily and quickly zip the mattress 1102 to the foundation 1104.

[0113] A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, the shape, size, and location of various components of the mattress, foundation, and zipper can be modified as suitable for the application. Similarly, one or more features present on one or more of the various embodiments can be considered optional, and need not necessarily be included in all embodiments. Accordingly, other embodiments are within the scope of the following claims.
