Abstract
Disclosed is a unitary foam seat cushion (10) that is configured and arranged to eliminate contact pressure on the rectal, perineal and genital regions of a person seated on the seat cushion without subjecting the perineal region to substantial stress or tension. The seat cushion includes a base (12) and two upwardly projecting elongate support members (16 and 18). The support members are of an arcuate (upwardly extending convex) cross-sectional geometry and are positioned in parallel spaced apart relationship for support of the ischia and thighs. Located between the support members is a channel (14) that extends downwardly into the seat cushion to form a void that prevents exertion of contact pressure on the rectal, perineal and genital areas. The portions (30 and 32) of the support members nearest the knees of a seated person taper downwardly for improved weight distribution and comfort of a person seated on the seat cushion.
