Abstract: A computer workstation extension designed to be used with a variety of different desks, tables and counters. The extension includes a rectangular-shaped planar member. Formed or attached to one end of the planar member is a longitudinally aligned overlapping lip member designed to be placed over the top surface of the desk, table or counter. In the preferred embodiment, a recessed space is formed over the lip member which is designed to receive a mouse pad. During use, the top surface of the planar member and the mouse pad are aligned and registered to form a flat, continuous work surface. The planar member is adjustably attached to the edge of the desk, table or counter by two single or bi-directional clamps located on the bottom surface of the planar member. The bi-directional clamps enable the extension to attach to different sized and shaped edges.
