A lift-pad assembly of adjustable height for use on a swing arm of a vehicle lift comprises a platform for contacting and at least partially supporting an undersurface of the vehicle, the platform being vertically adjustable in position while remaining horizontal by mounting it on the arm by means of pivotable support linkages the pivot axes of which are at the vertices of a parallelogram. Vertical positions for the platform other than fully up or fully down are provided by bars which can be interposed at will between the platform and a lower base support by operation of one or more slideable plates.
