Abstract: A body support cushion, e.g., mattress, has multiple foam layers, including a viscoelastic foam layer and a reticulated foam layer, and an outer cover. At least one of the foam layers and the outer cover each includes phase change material having latent heat properties that provide two intervals of dermal cooling.

Abstract: A thermal management composite, comprising a phase change material within a carbon or graphite matrix. The matrix is coated with a polymer coating to improve flexibility. The matrix can be a molded carbon or graphite material or a carbon or graphite cloth.

Abstract: A mattress assembly includes a first layer of viscoelastic foam defining an upper surface, and a second layer of non-viscoelasiic foam supporting the first layer. The mattress assembly also includes a plurality of static spring elements positioned beneath the upper surface for enhancing a firmness of the combined first and second layers.

Abstract: Mattress assemblies are provided that include a plurality of visco-elastic foam blocks configured to attach to one or more adjacent visco-elastic foams blocks. Bed assemblies are also provided that include the mattress assemblies and further include a frame having rails with a height that, upon placement of a foundation and the mattress assembly in the frame, cover at least a portion of a side of each visco-elastic foam block to thereby secure the visco-elastic blocks in the frame in a predetermined configuration.

Abstract: A mattress includes a first layer of viscoelastic foam having an upper surface and a layer of non-viscoelastic foam supporting the first layer. The mattress also includes a plurality of static bolster elements positioned beneath the upper surface and clustered together to define a plurality of troughs between adjacent bolster elements. The first layer of viscoelastic foam is further compressible in regions of the mattress corresponding with the troughs than surrounding regions corresponding with the bolster elements. Each of the bolster elements is capable of exerting a reaction force having a lateral component on an individual pushing against the bolster element with a line of action through one of the troughs.

Abstract: A body support assembly includes a body support having a head portion, a middle portion, and a foot portion. The body support assembly also includes a foundation underlying and supporting the body support proximate an edge of the body support at one of the head and foot portions, and a bracket coupled to the foundation and slideable between first and second positions at different distances with respect to the edge of the body support.
