The present invention relates to a hydraulic piston arrangement, preferably for use with reclinable and/or height-adjustable chairs. The seat (2) of the chair is acted on by a rod (8) which is connected to a piston (15). The piston is located in a liquid-filled space (16, 17) within at least one half (17) of which a compressible means (20) is arranged. In order to be able to adjust the device, the liquid communicates via a conduit (18) within which an adjustable valve (19) is provided. |
