ABSTRACT:
Disclosed is a portable seat and carrying case, combined in a single article of manufacture. The seat-case comprises first and second side wall members hinged to each other and rotatable between a closed, case-fashion position and an open, seat-fashion position. The side wall members are identical. Each identical side wall member comprises at each side thereof a pair of outwardly directed, concentric circular bearing surfaces, one being formed outside a projection and the other inside a recess. The projecting bearing surface of one side matches the recessed bearing surface of the other side of each of the side wall members, and, when coupled to each other, they form a hinged connection therebetween. A bottom member forms part of and rotatably supports the side wall members in their coupled position.
