Claim 6:
7. The apparatus of claim 1, wherein:
the actuator comprises a threaded rod that is rotatably mounted and vertically fixed in the post between an upper rotational bearing contained in the upper portion of the frame and a lower rotational bearing contained in a lower portion of the frame;
the actuator member is operably attached to the threaded rod and the work surface so that rotation of the threaded rod between the upper rotational bearing and the lower rotational bearing with the motor causes the vertical movements of the work surface within the range of movement; and
the actuator member comprises threads that are operable with corresponding threads of the threaded rod to
cause the vertical movements of the work surface when the threaded rod is rotated,
stabilize the work surface during the vertical movements, and
maintain a vertical position of the work surface at each height of the plurality of different work surface heights when the threaded rod is not rotated.
