A product upon which a person may lie down that includes a mattress whose underside has a peripheral flange that bounds a recessed cavity into which is placed an adjustable mechanism that can be actuated to raise or lower the head and foot portions of the mattress. The adjustable mechanism in its flattened state is hidden from view from the sides of the mattress by the peripheral flange.

A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to at least one adjacent string, each string comprising one piece of fabric folded into first and second opposed plies of fabric. Outer pockets are formed along each string by transverse seams joining the first and second plies. One pocketed spring and at least cushion pad is positioned in each outer pocket. The cushion pad may be individually pocketed. An upper end of each transverse seam may be below an upper surface of the string to partially separate adjacent outer pockets within a string.

A pocketed spring, such as that used in a mattress, comprises: a compression spring having an upper end convolution and a lower end convolution opposite the upper end convolution, and a plurality of helical intermediate convolutions between the upper end convolution and the lower end convolution; a flexible enclosure including a top wall positioned adjacent to the upper end convolution of the compression spring, a bottom wall positioned adjacent to the lower end convolution of the compression spring, and a side wall that extends from the top wall to the bottom wall; and a tension member connected to the flexible enclosure. The tension member acts in opposition to the compression spring until the pocketed spring is compressed to a point at winch the tension member no longer applies any force. Thus, the pocketed spring exhibits a non-linear response when compressed.

In systems and methods for adjusting the firmness of a mattress assembly and/or modulating the pressure in a mattress assembly, a mattress assembly includes: a two-dimensional array of bladders; at least one pump that is in fluid communication with the bladders to provide air and/or fluid to the bladders: multiple valves that are interposed between the pump and the bladders to control the flow of air and/or fluid to or from the bladders; a pressure sensor operably connected to one or more of the bladders; and a controller in communication with the pump, the valves, and the pressure sensors. The controller is configured to selectively actuate the pump and one or more of the valves, while receiving feedback from the pressure sensors, in order to adjust the firmness of the mattress assembly and/or modulate the pressure in the mattress assembly.

A coil-in-coil spring is provided that exhibits a variable and non-linear loading response upon compression. The spring comprises a continuous wire including a first spring portion having a first spring constant, a second spring portion having a second spring constant less than the first spring constant, and a third spring portion having a third spring constant less than the first spring constant and less than the second spring constant. In the coil-in-coil spring, the first spring portion forms an outer coil of the coil-in-coil spring and the second spring portion, the third spring portion, or both the second spring portion and the third spring portion are positioned within the first spring portion and form an inner coil of the coil-in-coil spring. A multi-coil spring is also provided that includes an outer coil, an intermediate coil positioned within the outer coil, and an inner coil positioned with the intermediate coil.

Spring modules for an adjustable sleeping system. At least some of the example embodiments are spring modules comprising: a spring rail, and a plurality of adjustable spring assemblies spaced along the length of the spring rail. Each adjustable spring assembly may comprise: a motor with a stator coupled to the spring rail via a load cell, a lead screw coupled to a rotor of the motor, and the lead screw extending above an upper surface of the spring rail, a spring plate coupled to the lead screw, and a main spring coupled to the spring plate. A tubular sock disposed over the main spring, and a compliant insert can be disposed between adjacent main springs to inhibit side loading and maintain the main spring in upright relation with the spring rail.

A mattress assembly includes a base core layer and an inner core located over the base core layer. The inner core includes coil springs. The mattress assembly also includes a side panel assembly located around a perimeter of the inner core. The side panel assembly includes a spacer fabric located over and transverse to the base core layer. The spacer fabric includes a first knit layer, a second knit layer, and an inner fibrous material located therebetween. Methods of forming the mattress assembly are disclosed.

A mattress topper includes a first layer, a second layer, and a third layer. The first layer and third layer are made of a foam material. The second layer is sandwiched between the first layer and the third layer. The first layer and the third layer are connected directly to each other.

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

A support cushion for providing air flow to a user resting on the support cushion is provided. The support cushion includes pocketed coil layer and a base layer positioned adjacent to and below the pocketed coil layer. The pocketed coil layer including a plurality of fabric types for directing air flow. A fan is operably connected to the inlet hole of the base layer to provide air flow into and through the pocketed coil layer to a body support layer. Methods of controlling air flow through a support cushion are also provided.
