Abstract
An inflatable bladder supports the body of a person and relieves pressure on a portion of the body not engaging the bladder. The bladder has at least one rear chamber adapted to receive and maintain a first charge of fluid. At least one front chamber supports the legs of the person and has two support legs. The support legs are spaced apart from each other to form a channel between the support legs. The channel is sized and shaped for placement beneath a portion of the body to relieve pressure on the portion. The front chamber is adapted to receive and maintain a second charge of fluid separately from the rear chamber.
