a processor linked to the memory device and the drive mechanism and controlling the drive mechanism to move the worktop to different positions; and
a user interface supported by the worktop, the interface including an upper surface and a lower surface that face upwardly and downwardly, respectively, the interface further including at least one sensor for sensing contact with the upper and lower surfaces, respectively, the interface linked to the processor, the processor programmed to perform the steps of;
(i) while the worktop is in the first sitting position;
(a) upon sensing a quick upward double activation of the user interface, controlling the drive mechanism to move the worktop from the first sitting position to the first standing position; and
(b) upon sensing a prolonged single upward activation of the user interface, controlling the drive mechanism to move the worktop upward from the first sitting position toward the first standing position and continuing to drive the worktop upward as long as the prolonged single upward activation persists.
