ABSTRACT:
A foldable chair comprising a pair of front legs, a pair of rear legs, and linkage systems interconnecting the legs. The chair is characterized in that each linkage system consists of a pair of compass-like frame members and a respective pair of crosswise extending link arms. The linkage system is designed so that when the chair is in its folded position it forms into a compact package whereby the legs extend in close parallel relative positions.
