ABSTRACT:
A contour chair, mounted for powered articulation on a pedestal, which includes a plurality of transversely aligned flexible containers disposed over the support surface thereof, each container communicating across a corresponding check valve with a common manifold. The other end of the manifold is connected to a pressurized source of water whereby an even distribution of surface pressure is achieved in the support surface of the chair. To provide for retention of a person seated in the chair during the articulation thereof on the pedestal, there is included on the back support area thereof a neck brace adjustable to accommodate various sized torsos. Included further with the chair are two arm rests, one provided with the requisite control buttons for articulating the chair, and the other being hinged to allow convenient ingress and egress onto the chair.
