ABSTRACT:
A portable back and arm support device for use on a bleacher-type bench seat which incorporates a simple back support and two arm supports hingedly connected to the back support. Each arm support may be folded inward so that each arm support is in a parallel relationship with the back support as well as with each other in a tight, transportable arrangement, or each arm support may be folded outward in its operation position so that each arm support is in a somewhat perpendicular relationship with the back support. Each arm support contains a unique fulcruming arrangement which allows the arm supports to constrict, thereby attaching to, or "grasping" onto a bench-type seat by fastening to the mere edges of such bench-type seat.
