Abstract
An active arm support is provided for a chair which takes the weight of the arms and forearms off the shoulders, back and neck of the user while typing so as to support the arms of a typist in the same manner that a chair supports the body. The active arm support provides full arm and forearm support and is vertically adjustable and laterally adjustable and pivots horizontally and vertically while fully supporting the entire forearm. A hinge with a variable spring provides an assisted vertical lift while fully supporting the entire forearm. The presently disclosed active arm support releases the upper trapezius muscles from efforts to support the arms and forearms to provide relaxation in the neck and shoulders of the user, while actually performing typing and other tasks.
