Abstract
A seating system for a wheelchair including a base member and fluid pad. The base member has forward and rearward sections respectively supporting the user's thighs and buttocks. The rearward section supporting the user's buttocks includes a depressed, seating well with front and rear upper surfaces. The fluid pad has a front-to-rear, center seal and a transverse seal dividing the pad into four pouches. The transverse seal crosses the center seal substantially closer to the rear of the pad than to the front and substantially midway across the seating well. In use, the pad is positioned on the base member wherein the user's thighs and front of the user's buttocks are supported on the forward pouches which, in turn, are positioned over the forward section of the base member and the front portion of the seating well of the base member. The remaining, rear portion of the user's buttocks is supported on the rear pouches over the rear portion of the base member.
