ABSTRACT:
A flexible seat cushion, such as a wheelchair cushion, has an upper surface with a support contour for establishing relatively less pressure on skin adjacent to the bony prominences of the person's pelvic area and relatively more pressure on skin covering adjacent tissue masses. A support member is attached to the rear corner of the cushion. The support member has relatively less flexibility than the seat cushion. The support member is retained to a longitudinal and/or transverse side of the cushion to cause the support member to resist deformation of the support contour from contact with the pelvic area of the person when seated on the seat cushion. Connector member may be connected to the support member to extend along longitudinal and/or transverse sides of the cushion to deform and thereby adjust the support contour for better support of the pelvic area.
