A mattress includes a first, phase changeable component and a thermal management system adapted to control the temperature of the phase changeable component in order to change the firmness of the mattress. In one embodiment the phase changeable component includes two dimensional lattices separated from each other and a spring element extending between the lattices. Some embodiments of the mattress include an optional single phase component. The firmness can be made spatially and/or temporally uniform or nonuniform, and can be controlled based on one or more sensed parameters.

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.
