An apparatus for positioning items such as an electronic display, a keyboard, and/or a work surface. The apparatus includes a movement mechanism that provides multiple tilt positions for one or more displays supported by the apparatus. In some cases the movement mechanism enables adjustment of the display(s) between a generally horizontal viewing configuration and a generally declining viewing configuration. In some cases the apparatus includes a keyboard tray and a display mount coupled to a riser adapted to support an electronic display. The riser may be movable with respect to an operator or support member between a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.
