A support for a CRT monitor provides translational movement for the monitor in two perpendicular directions. The support is on rollers for movement over a horizontal surface, and includes telescoping arms for movement in a first direction. One of the arms enters an elongate guide channel mountable on the surface and includes rollers for rolling along a vertical wall of the channel so that the support moves in a second direction perpendicular to the first. The channel includes a cover and end walls.
