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.
