Modular mattress

Abstract

A mattress is disclosed, comprising two layersa first layer and a second layereach layer comprising a top surface and a bottom surface that are distinct in firmness, feel, and/or other parameters relevant to sleeping. The first layer and the second layer are stacked on top of each other and may easily be flipped and re-stacked by a user in the home.

Description

LIST OF FIGURES

(1) FIG. 1 shows a view of an embodiment of the present invention.

(2) FIG. 2 shows a view of an embodiment of the present invention from the side.

(3) FIG. 3 shows a view of an embodiment of the present invention from the top.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(4) For purposes of the present disclosure, a layer is a self-contained part of a modular mattress with surfaces that may have distinct firmness levels.

(5) FIG. 1 shows the preferred embodiment of the present invention. As can be seen, a mattress 100 is provided that comprises a first layer 110 and a second layer 120. The first layer 110 and the second layer 120 are roughly parallelepiped in shape. The first layer 110 is stacked on the second layer 120. A friction-enhancing sheet (not shown) is placed between the two layers; in some embodiments, the friction-enhancing sheet is not used.

(6) As can be seen in the Figure, each layer has a top side and a bottom side, which are distinct from each other in feel and/or surface hardness. Each layer may be placed on top or on the bottom, depending on consumer preference; i.e. the first layer 110 may be placed on top of the second layer 120 or the second layer 120 may be placed on top of the first layer 110. This results in eight possible mattress configurations with no parts left over. The only work that the consumer has to do to reconfigure the mattress is to flip over and/or re-stack the two layers.

(7) In the preferred embodiment, the dimensions of the two layers, when stacked together, are preferably the same as the dimensions of a standard mattress, to make it easier to use standard sheets on the mattress of the present invention. Any standard mattress dimensionsi.e. twin, full, queen, king, California king, or any other standard dimensionsmay be used for the present invention.

(8) While it is understood that the first layer and the second layer can have any softness/hardness levels or any other parameters on their top and bottom sides, FIG. 2 shows one possible embodiment of the present invention. The first layer 200 comprises a latex sleeping surface 210 on the top side and a gel memory sleeping surface 220 on the bottom side. The second layer 250 comprises a firm high-density foam 260 on the top side and a soft high-density foam 270 on the bottom side. As shown in the Figure, this allows the user to easily create eight different mattress typesa firm high-density foam mattress with a gel base, a firm high-density foam mattress with a latex base, a soft high-density foam mattress with a gel base, a soft high-density foam mattress with a latex base, a latex-topped mattress with a firm base, a latex-topped mattress with a soft base, a gel-topped mattress with a firm base, and a gel-topped mattress with a soft base. The only thing the user has to do to change the mattress type is flip one or both of the layers or move one from bottom to top or vice versa.

(9) In the preferred embodiment, one or more nonslip sheets 280 are placed between the first layer and the second layer to prevent slipping. The nonslip sheets are preferably non-skid pads such as those used for carpeting or furniture, but could also be Velcro or any other material that prevents one layer from slipping on the other layer.

(10) In the preferred embodiment, the top and bottom sides of each layer are different colors to indicate which texture/softness is which. As shown in the Figure, the latex side of the first layer has a dark top panel and the gel side of the first layer has a light top panel; the first layer has a light side border. The firm side of the second layer has a dark top panel and the soft side of the second layer has a light top panel, and the second layer has a dark side border. It will be understood that this is simply an example of the type of color labeling that could be used, and that any colors, patterns, or combinations of colors and patterns, may be used to distinguish the different sides.

(11) While the first layer as shown in the Figure comprises gel and latex as the two types of sleeping surface, it will be understood that any other sleeping surfaces may be used on either or both sides of either layer. For example, innersprings, memory foam, latex foam, and so on may all be used. Furthermore, while the second layer in the Figure comprises hard foam and soft foam as the two sides, it may also comprise innersprings, air or water compartments, gel, memory foam, and so on. In the preferred embodiment, half of the thickness of each layer is used for each texturei.e. for a given layer, half the thickness may be comprised of gel and half of memory foam, and so on. In some embodiments, different percentages of the total thickness of each layer are used for each texturefor example, 75% of a layer may be comprised of innersprings and 25% of gel, and so on.

(12) In an embodiment shown in FIG. 3, one or more of the layers may comprise handles 300 to make the layer easier to flip. The handles may be made of strapping material or any other material that is strong enough to support the weight of the layer in question. The handles are preferably located in such a way as to provide two points of support for the layer as it is being flippedfor example, at and the length of the long side of the layer.

(13) In the preferred embodiment, no fasteners are used to attach the two layers to each other; this simplifies the design and makes it easier for the two layers to be used in either configuration. Similarly, no mattress cover is used in the preferred embodiment; rather, the two layers are simply stacked on top of each other. Putting a mattress cover on a mattress is generally a very difficult task for a consumer in the home, so omitting the mattress cover simplifies the steps of reconfiguring the mattress.

(14) Exemplary embodiments are described above. It will be understood that the present invention encompasses other reasonable equivalents to the embodiments described above, as is evident to a person of reasonable skill in the art of mattress design.
