Abstract
A portable, fold-up sports chair includes fabric seat and back portions, attached to and extending between a lightweight, collapsible tubular frame. The transverse frame members are hinged to allow the chair to be folded into a compact bundle for transportation or storage. Straps attached to the underside of the legs help prevent the chair legs from penetrating or sinking when used on a soft surface such as sand. The angle of the seat back is adjustable by means of straps which also serve as arm rests when the chair is in use.
