Abstract
A portable back rest adapted to be detachably mounted onto stadium bleacher seats and the like. The back rest is formed of a single piece of flexible material and comprises a back panel, a pair of side panels hingeably connected thereto, and front and rear locking elements adapted to securely grip the bleacher seat. In its transport configuration, the side panels fold inwardly into close proximity with the back panel, thereby forming a compact readily portable unit.
