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: A support cushion is provided for dissipating heat away from the support cushion. The support cushion includes a body supporting portion and a base portion that is positioned below the body supporting portion. The base portion defines a channel that extends through the base portion and that is in fluid communication with the body supporting portion. A fan is further included in the support cushion and is operably connect to the channel of the base portion, such that the fan is positioned and configured to move an amount of air through the channel and dissipate heat away from the body supporting portion. Methods of dissipating heat away from a support cushion are also provided.

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 cushion includes a foam body having first and second lateral support portions defining an elongated recess therebetween. The cushion can also include a cover at least partially enclosing the foam body and means for releasably coupling the cushion to a support member to facilitate transport of the support member and the cushion as a unit. Also, the cushion can include another body positioned in the recess, removable from the recess for use in supporting a lumbar or posterior area of a user, and releasably attachable within the recess by one or more fasteners.

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.
