A pair of upper lateral wing frame portions extend from the upper section of the central portion, and a pair of lower lateral wing frame portions extend from the lower section of the central portion. The unitary cushion is shaped to fit over the frame and comprises, a generally rectangularly shaped central cushioned portion having upper and lower sections, a pair of upper lateral cushioned wing portions extending from the upper section of the cushioned central portion and a pair of lower lateral cushioned wing portions extending from the lower section of the cushioned central portion. The pairs of upper lateral wing frame portions and lateral cushioned wing portions, provide bracing to the left and right sides of the person's upper torso in a substantially upright position. The pairs of lower lateral frame wing portions and the upper lateral cushioned wing portions, prevent rotation of the person's pelvis.
