ABSTRACT:
A self-releveling, height adjustable, hydraulically operated desk and a hydraulic circuit therefor are disclosed in which the desk top is supported for vertical movement upon master and slave rephasing cylinders connected in series. The desk top may be releveled by extending the cylinders to their limits of extension. The desk and circuit may include a height adjustable monitor support. The monitor support may also be supported for vertical movement upon master and slave rephasing cylinders for self-releveling. The hydraulic circuit includes check valves to prevent the desk top and the monitor support from being raised with respect to the supporting structure except upon activation of the hydraulic pump.
