ABSTRACT:
A collapsible keyboard support tray has folding legs. The legs have risers to enable adjustment of the deck to a height so that the hinged tray depends at an approximate negative 25.degree.. The deck has a height to support a wrist pad at just below the user's wrist to enable typing with a zero degree angle from the wrist to the forearm. The user adjusts his chair to create a 90.degree. angle from his forearm to his upper arm during typing.
