A backrest for a chair comprising a frame, a membrane and a back support member. The membrane, at least a portion of which is transparent, is attached to the frame and has a first body-contacting surface and an opposite second surface. The back support member is attached to the frame and has a support surface. At least a portion of the support surface contacts the second surface of the membrane, and at least a portion of the back support member is visible through the membrane from the first body-contacting surface thereof. In another aspect, a backrest for a chair comprises a frame having a pair of side members, wherein each of the side members has a lower section and an upper section. The upper section extends rearwardly and outwardly from the lower section so as to form a bowed section therewith. A flexible membrane is attached to and extends between the side members, and has a bowed section corresponding to the bowed section of the side members. The membrane has a first body-contacting surface and an opposite second surface.
