Abstract
A butterfly chair, capable of rapid assembly, includes (a) a framework that includes two U-shaped members, the first having a lower cross piece and two first legs that project upwardly and forwardly, and the second having a lower cross piece and two second legs that project upwardly and rearwardly, (b) pivots interconnecting the first and second legs at two locations, so that the members may swivel between collapsed and extended positions, (c) the legs restrained against collapse in said extended positions, and (d) the upper terminals of the legs being hook shaped for loose reception in pockets of a flexible sheet providing a seat and backrest.

In a folding knock-down chair construction adapting the chair to rapid assembly, the combination comprising:
- (a) a framework that includes two U-shaped members, the first having a lower cross piece and two first legs that project upwardly and forwardly, and the second having a lower cross piece and two second legs that project upwardly and rearwardly,
- (b) pivots interconnecting the first and second legs at two locations, so that said members may swivel between collapsed and extended positions,
- (c) means restraining collapse of the legs in said extended position, and
- (d) the upper terminals of said legs being hook shaped and loosely and conformingly received in corner pockets of a flexible sheet providing a seat and backrest, and
- (e) the upper hook shaped terminals of the second legs extending in offset relation to, and mounted to rotate freely about, longitudinal axes that are defined by said second legs, so as to rotate and thereby conform the backrest to the configuration of the sitter.
