Abstract
The back support is constructed from a back brace of elastic material which carries a gel pad and an air bladder. The brace supports the pad against lower back of the user in firm engagement. The air bladder is juxtaposed and generally co-extensive with the pattern containing the gel-like material. The air bladder has three individually inflatable chambers so that the user may adjust the pressure exerted on the pad and hence the support of the lower back. The gel pad may also contain a heating element to electrically heat the gel-like material. A rheostat may be provided for regulation of the heat.
