Abstract
Abstract A wrist rest is disclosed for use with a keyboard. The wrist rest includes a bladder for holding a fluid, a pump operatively connected to the bladder for selectively filling the bladder with fluid and a valve for selectively releasing fluid from the bladder. The bladder preferably includes two elongate lobes interconnected by an isthmus. The lobes are shaped so that the perimeter of a horizontal cross-section through one of the elongate lobes is substantially elliptical in shape.
