<p>An office-type chair has with a base (16), a seat-back arrangement (11) including a seat assembly (12) which is vertically tiltable relative to the base (16) and a back assembly (13) which is vertically tiltable relative to both the seat assembly (12) and base (16), and a tilet control mechanism (21) operatively coupled between the base (16) and the seat-back arrangement (11) for permitting the back assembly (13) and seat assembly (12) to be respectively rearwardly and downwardly tilted away from an upright position in a synchronous but differential rate. A front tilt control device (77, 97) is associated with and interconnected with the tilt control mechanism (21) for permitting the seat and back assemblies (12,13) to be synchronously and nondifferentially tilted away forwardly away from the upright position. <IMAGE></p> |
