The gas pressure spring is a pneumatic spring in the best quality class. Gas under high pressure generates the required spring force. The cylinder and the freely movable piston have an integrated damping mechanism and thus allow a smooth up and down lifting. Due to the conical plug-in connection, the gas pressure spring can be used for almost all common office chairs/executive chairs - especially for continuous load and higher load. The gas pressure spring is very easy to install, has a long service life and a maximum load capacity of 180kg.
