Abstract
Abstract The keyboard Foreman Wrist Rest is a solitary cushioned, rigid platform that positions the hands and wrists ergonomically in front of the keyboard. The lateral extensions of this solitary platform support the arms in a manner that minimizes damage to the vital structures of the wrists and reduces shoulder fatigue. The basic unit is attached to a rigid sheet which rests upon the workstation, upon which the keyboard, plus central processing unit, and/or monitor are placed. A second embodiment includes a keyboard platform which extends from the basic unit, that can be detached from the workstation proper.
