Abstract: A wrist rest assembly for use along the front edge of a device to be operated by a person's hands or fingers, such as in front of a computer keyboard, including an elongate base on which is supported an elongate pad comprising a layer of gel within the covering. The pad has sufficient thickness between its top and bottom surfaces and width between its edges to afford supporting a users wrists on said top surface with a portion of the layer of gel beneath and conforming to the supported wrists and to afford significant motion of the top surface of the pad with the supported wrists relative to the bottom surface in a plane generally parallel to the upper surface of the base. The base has a top portion supporting the pad, a bottom portion adapted to be supported on a horizontal surface; and structure that allows the top portion to be supported on the bottom portion with the top surface of the pad at a predetermined one of several different distances above that horizontal surface.
