Abstract

An article of furniture, such as a chair, including a free-swinging seat and a free-swinging backrest. The chair includes a seat and backrest coupled to a chair frame, where the chair frame includes first and second laterally spaced apart components. The first and second components each have a floor strut and a pair of legs that may be arranged in a substantially triangular configuration for supporting the seat. The chair also includes a coupling device, which may include a spring element, coupled to the legs and configured to allow forward movement of the seat and backward movement of the backrest, where movement of the seat and backrest may occur independently of one another. In some embodiments, the maximum movement of the seat and backrest may be limited by restricting movement of the coupling device.
