Abstract: A foam overlay (A,A') is disclosed which includes a rectangular base (C) and a plurality of individual and independently acting foam springs (B,B'). Each foam spring includes a base block (10,10') and a polyhedron body (14,14') atop each base block terminating in a planar support surface (12,12'). The foam springs are close enough to each other, yet separated sufficiently that they each act individually and independently. The foam springs may act together to support heavier portions of the body, but act independently in support of lighter body portions. Medical overlay pad (A') includes a main support section (32) and a secondary support section (30) of shorter foam springs D. Foam springs (B') of main section (32) support at a higher level than foam springs (D) of secondary support section (30). This allows pressure to be reduced on the lower extremities, such as the heel, during prolonged bed rest as well as on upper torso.

Abstract: A foam pillow has two main support surfaces on opposing sides thereof. One surface includes convolutions defining a relatively flat profile and the other surface includes longitudinal ribs of arcuate cross-section, which define a curved profile having at least two prominent lobes of differing heights and a central trough. The pillow is particularly adapted for support of a person's head in the trough, with the user's neck received on one of the lobes. Reversal of the lobes permits variation in the amount of neck support. The ribs comprise spherical ridges and have circular channels separating their bases to provide a heat and moisture dissipation function. The curved support surface may include cross-hatching at various intervals to provide extra dispersion of pressure.
