An adjustable keyboard support is disclosed constituted by a rear housing that pivotally supports one end of a parallel link mechanism. A front housing is carried by the other end of the parallel link mechanism, and pivotally supports a keyboard mounting plate. The parallel link mechanism permits upward and downward movement of the keyboard mounting plate without change in the tilt of that plate. A gas cylinder mechanism coupled to the front housing changes the vertical position of the same, and a slide plate adjustment mechanism provides forward and backward movement of the keyboard mounting plate.
