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.
