Abstract
A frame for a desk to support a work surface for height adjustment of the work surface. The frame includes a base frame consisting of a pair of vertical members which are generally parallel, co-extensive and transversely spaced. The vertical members of the base frame receive a pair of vertical members of a height adjustable sub frame. A rotatably driven first shaft causes vertical movement of an associated pair of vertical members on one side of the desk while vertical movement is transferred to the other side of the desk by a second shaft having gears which engage a rack gear on each of the vertical members of the sub-frame.
