ABSTRACT:
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 performs 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.
