ABSTRACT:
A folding chair is formed of an integral tensile structure having eight articulated compression members with inner ends transfixed by a central ring. The outer ends of the compression members are joined by cables and a concave fabric seat to hold the chair in a usable position, one cable being released to collapse and fold the chair. To maintain the orientation of the ring on unfolding the chair, the inner ends of two compression members have engaged teeth formed thereon.
