Abstract

A small-sized, ultra-lightweight chair that collapses into a small diameter bundle for easy storage or carrying by hand, in a bag or case, on one's back, or in a backpack, and the like. The chair comprises a front scissor-linkage and a rear scissor-linkage, which are laterally-inwardly foldable to provide for the collapsible nature of the chair. The front and rear scissor-linkages are interconnected by a crossed pair of cords, one pair connecting the scissor-linkages on one lateral side of the chair and the other X-shaped cords connecting the scissor-linkages on the other lateral side of the chair. The scissor-linkages are made of light-weight, rigid slats, the upper ends of the slats of which mount a rectangular piece of fabric for providing the seat proper upon which one sits. The lower ends of the slats of the front scissor-linkage are coupled to the lower ends of the slats of the rear scissor-linkage by a pair of folding braces, one brace for each lateral side of the chair.
