Abstract
Abstract A device for supporting a keyboard user's wrists while typing-or entering data at a keyboard is disclosed. The wrist supporting device includes a flexible tubular member fastened, with blind fasteners, to a tray on which keyboard rests. The top surface of the tubular member is positioned horizontally, in normally fixed relation above and along the front edge of the keyboard. The tubular member is made from a flexible material such as conventional polyurethane or vinyl tubing, that allows the top surface of the member to flex toward the top edge of the keyboard when the user's wrists are resting on the member.
