A suspension system having a four bar linkage system including an angled arm for adjustable and positionable vertical and horizontal support of a video monitor or the like. A weight counterbalance adjustment mechanism adjustably compensates for various weights of a load held by the angled arm. Gas springs provide for vertical support of the angled arm. 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..
