ABSTRACT:
A lower back support comprising two elongated cylindrical tubular members composed of polyurethane foam and held in side-by-side relation in proper position against a user's back by an elongated flexible strap support which permits a limited rolling action of the members against the back. The strap extends loosely through one member, and then loosely through the other from opposite ends, then forming a loop of adjustable size passing under the user's arms and around the back of the neck. VELCRO-type fabric strips on the strap form a connection of adjustable length.
