Abstract
A seating system for wheelchairs and other applications. The seating system includes a base member with an upper surface and a fluid pad positioned on the upper surface. The upper surface is preferably contoured and dimensioned to have areas corresponding to the user's ischial tuberosities and coccyx as well as the user's femurs including trochanters. The fluid pad in the preferred embodiment is one piece and has at least three separate and distinct pouches filled with fluid. Each pouch includes seals to contain the fluid in each pouch and to isolate and prevent fluid communication with the fluid in the other two pouches. Each pouch of the pad is then respectively positioned on the upper surface of the base member under the user's ischial tuberosities and coccyx. In this manner, each of the user's ischial tuberosities and coccyx is thereby supported on its own separate and distinct fluid pouch.
