Abstract: A chair assembly has a seat set, two front multi-connectors, two rear multi-connectors, two front leg members and two rear leg members. The seat set has two transverse bars and two longitudinal bars. Each of the front and rear multi-connectors is mounted between adjacent transverse bar and longitudinal bar. The front leg members are mounted respectively on the front multi-connectors. The rear leg members are mounted respectively on the rear multi-connectors. The front multi-connectors and the rear multi-connectors connect the seat set, the front leg members and the rear leg members together without forming tenons and mortises on the front and rear leg members, which simplifies manufacturing process of the chair assembly.
