Abstract: A motor driven vertically adjustable work surface or desk which is optimized to support a substantial load of equipment cantilevered toward the front of the surface. The work surface is supported by a pair of motor driven telescoping legs having internal rolling bearings and rack and pinion drive arranged to eliminate sliding friction and maintain smooth motion. The telescoping legs are mounted toward the rear of the work surface and supported on a base or wall so as to provide maximum clearance under the front of the desk to accommodate wheelchairs and the like.
