The invention is a keyboard tray which is formed from two relatively shallow molded bodies united along a periphery thereof to define an internal relatively flat chamber in which is slidable a mouse tray. The mouse tray can project outwardly of the chamber through either of opposite side edges of the keyboard tray. The mouse tray carries a projection which limits sliding movement of the mouse tray in its opposite directions. A rigid block of wood is secured in a recess portion of the keyboard tray to afford rigidity thereto and provide frictional purchase for screws which secure the keyboard to a keyboard tray mounting or support arm.
