A support contour of a cushion, such as a wheelchair cushion, defines relief areas at locations adjacent to skin covering the ischial tuberosities, the greater trochanters and the coccyx and sacrum of a person sitting on the support contour. Support areas of the support contour transfer force into the pelvic area adjacent to skin covering tissue masses on opposite lateral sides of the posterior buttocks and beneath the proximal thighs of the person. Greater clearance is also provided in the perineal area. Risks of pressure ulcers from pressure and shear forces on bony prominences is reduced while providing support at the broader areas without bony prominences in such a manner to encourage postural alignment. The risks of skin breakdown perineal are diminished.

A flexible support structure of a seat cushion, such as a wheelchair cushion, has an upper surface with a support contour having relief areas for establishing relatively less pressure on skin adjacent to bony prominences of a user's pelvis and having a support area for establishing relatively more pressure on skin covering a tissue mass spaced from the bony prominences. A slit is formed in the rear corner of the support structure and an insertion member is inserted into the slit to change a position of the support area to thereby adjust the support contour for better support of the pelvic area. A cover encases the support structure to resist outward deformation of the support structure. The cover has an extension portion that expands the cover at the rear corner to increase a dimension of the cover to encase an increase dimension of the corner caused by the insertion of the insertion member.

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.
