A contoured seat generally includes a seat surface for supporting the thighs and buttocks of a sitter and a back surface for supporting the lower back of a sitter. Defined by the seat surface are a pair of bilateral, spaced protrusions that are positioned to extend into piriformis musculature of the sitter. Preferably, the seat surface is inclined at a 5° to 15°, and more preferably a 7.5°, angle to induce forward pelvic tilt in conjunction with lower lumbar support of a forward angle of the back surface. The seat and back surfaces may define a sacral-coccyx pocket that has a depth that varies, along its proximal-distal path to allow for sacral stabilization. The sacral-coccyx pocket preferably is relatively narrow and deep proximally and flares as it extends in the distal direction. A reinforcing ridge may extend across a top edge of the sacral-coccyx pocket to provide additional support.

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 wheelchair seat cushion has multi-density regions. The cushion assembly may have a region having a stiffer, higher density proximate the front of the seat cushion assembly beneath the user's thighs to assist the user in exiting the wheelchair.
