Modular cushion construction with foamed base
First Claim
1. A shaped base made from expanded foam having(a) a substantially flat rear portion to accommodate a pad for supporting the buttocks of a user,(b) a raised front portion having a central pommel to separate the legs and side edges which define curved depressed leg areas adjacent to the pommel to place loads on the legs of the user, the depressed leg areas being angularly inclined in a diverging direction toward the front of the base to position the user, and(c) an angularly inclined stepdown section connecting the flat rear portion and the raised front portion to provide a transition which minimizes deformation of the soft tissues of the user which are positioned above this part of the base,(d) said rear portion extending from the back edge of the base to the stepdown section and completely across the base from side-to-side, said rear portion being of substantially uniform thickness throughout.

Abstract
A modular cushion comprising a shaped base which has a flat rear portion and a raised front portion with angularly directed valleys and a raised pommel to direct weight to the thighs and in combination with a resilient pad positioned on the flat portion of the base to relieve pressure on the ischial and trochanters and in combination with a cover having a non-skid undersurface and a portion of the top being two-way stretchable. The resilient pad may be of inflatable cells having a pyramidal shape with a flattened top. A U-shaped restraining member may be positioned at the front of the base with upwardly projecting sides to retain the legs of the user.
