Abstract: A desk unit incorporating a concealed pull-out keyboard well includes a work surface and a concealed keyboard platform mounted under a work surface. The work surface can have an apron on the lower front surface that conceals the keyboard platform. A movable section of the work surface at a front edge thereof is movable in a path that extends downwardly and under the front edge of the keyboard tray and then rearwardly under the keyboard tray, where the movable section can be stored or removed from the desk unit. When the movable section is thus positioned, the keyboard can be used or extended for use. This desk construction can be employed in a corner mounted desk, wherein the keyboard tray is mounted at an angle under a corner in the desk, or the invention can be employed in a conventional desk having a work surface with a straight front edge.
