ABSTRACT:
A portable seat pad of the seat and back element type said back element having an inflatable bladder removably mounted for adjustment vertically along the outer side thereof. The back element is sufficiently rigid along its peripheral edges for making it self-supporting but the body portion is sufficiently flexible so that the force of the bladder deforms the body to form a lumbar support in the body portion. The adjustment is preferably accomplished by a hooked and napped loop tape means mounted on the outer side of the back element and on the inner surface of the bladder. Further, a cover is provided to cover the outer surface of the back and assist in holding the bladder in place. Preferably hooked and napped loop means secures the cover to the back.
