Abstract

A leg assembly for a chair includes four legs, a pair of lateral beams each interconnected between two of the four legs, and a pair of transverse beams interconnected between the lateral beams. A seat cushion is mounted on the transverse beams and has a plurality of nuts attached to an underside thereof. Each lateral beam includes two spaced tubes extending therefrom toward the other lateral beam, each tube having a first transverse bore defined therethrough. Each transverse beam includes two reduced ends each having a second transverse bore defined therethrough. The reduced ends of each transverse beam are respectively received in two aligned tubes respectively on the lateral beams, and a plurality of bolts are extended through the aligned first and second bores and then engaged with the associated nuts mounted on the seat cushion.

Claims
