An adjustable keyboard support, for holding keyboards for computer terminals, drawing boards, digitizing pads and similar items, comprising a support frame which is pivotally mounted below the top surface of a terminal support stand. The support frame has spaced extendable and retractable side members, each side member having a rear member and front member. Each front member is slidably mounted on a rear member. Each rear member is pivotally attached at its rear end to the terminal support stand. A lever extends between a forward part of the terminal support stand and an intermediate position on a forward member, for each side member. Extension of the support frame swings the levers around and forward, the front members first moving down further extension causing the front member to move up as continued swinging of the levers occurs. In a further embodiment, the support provides a moveable keyboard carriage. The carriage may be vertically elevated and angularly inclined with respect to the support frames; suitably positioned levers facilitate the motion.
