Mobile computer workstations must be sufficiently large in order to be stable, but small enough to be easily maneuverable through a work place. A vertically-adjustable mobile computer workstation of the present disclosure includes a pole rotatably attached to a base supported by a plurality of rotatable members. The pole includes a first arm rotatably attached to a second arm. A computer support is attached to the second arm and is moveable between a sitting user position and a standing user position, at least in part, by pivoting the arms of the pole with respect to one another and the moveable base.
