ABSTRACT:
Variably adjustable chair (100) having adjustable arms for optimal positioning by a user to attain greater comfort and operation with reduced stresses and tensions. Each adjustable arm assembly (198) and (199) includes keyboard supports (195) and (196) and auxiliary supports (145) and (146). Keyboard supports are for use with keyboard sections. Right and left keyboard sections (200) and (300) are divided for independent right- and left-hand actuation. More specifically, a standard computer keyboard, QWERTY keyboard layout, with a numeric data pad, is divided at an optimum location for normal left-and right-hand usage. Each keyboard section includes keys which are optimally positioned for natural orientation actuation by an operator's thumb. Wherein, each adjustable arm assembly and each keyboard section is ergonomically designed for an operator's natural arm-hand-wrist contours for optimal use and comfort with reduced stresses and tensions.
