ABSTRACT:
A chair assembly consists of a seat, a back, one or more leg members and a mounting plate. The seat, back and leg members are removably mounted to the mounting plate, for allowing such components to be removed and replaced as desired. The back includes a mounting arm, the end of which is pivotably connected to the mounting plate. A spring is interposed between the mounting arm and the plate, for biasing the back to an upright position. Each leg member includes an upper mounting portion, mounted to the plate by threaded fasteners such as screws or the like. The plate includes an upper surface which engages a lower surface defined by the seat. Threaded fasteners are employed to mount the seat to the mounting plate. The major components of the chair are thus removably mounted to the mounting plate, for providing modular assembly and facilitating ease in replacing some or all of the components of the chair.
