Configured slots in which the upper ends of the gas springs position provide for minimal manual positioning effort and a linear counterbalance throughout the entire range of vertical adjustment. An arm bent at an angle of 120.degree. overcomes the traditional interference of the load with movement of the arm beyond 45.degree..
