Abstract
A wrist rest (1) of specially designed height and other characteristics is provided for reducing strain on the wrists and hands of a keyboard operator or a similar user of computer accessories. The rest (1) is made to be placed in front of the keyboard or accessory being used, and may be designed to have a particular firmness for comfort. In some embodiments the rest has two foam rubber layers (20,30) about 3/4 inch thick total; the bottom surface has no "skin", to prevent the rest from slipping, while the upper surface has a smooth covering (10) so hands may slide around easily and comfortably. In order to allow rests designed for a normal keyboard to be adapted for use with an especially long keyboard, or with an accessory like a mousepad (4), one embodiment (3) of the invention has contours (101) which can interlock with similar contours (100) on an extension pad (2); these contours are also designed to be easily and inexpensively manufactured.
