Abstract
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 assembly on which is supported an elongate pad. The base assembly 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 two different distances above that horizontal surface by switching ends of the top portion with respect to the ends of the bottom portion.
