The gas spring suspension comprises a gas-tight container capable of longitudinal expansion and contraction and on which the seat is supported, a valve system for connecting the container selectively to a compressed gas source or to exhaust to raise or lower the vehicle seat, a telescopically slidable coupling connected at one end to one end of the gas spring and including a detent which locks the slidable parts of the coupling together at a selected relative position corresponding to a selected vehicle seat height and a mechanical spring coupling connected between the other end of the slidable coupling and the other end of the gas spring, the spring coupling being expandible and contractable between end stops which thereby limit the resilient expansion and contraction of the gas spring, at any selected seat height, means for releasing the detent prior to operation of the valve system, and means fo automatically terminating the inlet of compressed gas into the gas spring in response to the slidable coupling becoming fully extended.
