A workstation for use in a healthcare facility, the workstation comprising:
(a) a work surface having a top surface and a bottom surface, the work
surface having means for carrying healthcare equipment;
(b) a pedestal for supporting said work surface, said pedestal being
vertically adjustable so as to adjust the work surface between a standing position
and a sitting position;
(c) a movable base for supporting said pedestal; and
(d) a counterbalance attached to the bottom surface of the work surface,
said counterbalance counterbalancing weight of the healthcare equipment carried

Wacker discloses a modular work station having a dual column construction with a
separately adjustable work surface supported on each column. Each of the columns
utilizes a tubular telescoping construction and can provide as many as three individual
modes of adjustable movement to the work surface, including lift, tilt, and horizontal back
and forth movements. The lift and tilt functions are preferably provided by motor driven
linear actuators mounted within the telescoping column with appropriate controls to prevent
contact between adjacent work surfaces when one or both of the surfaces is also provided
with back and forth sliding movement. As shown in Figures 1 and 2, adjustable work table
10 comprises a base 12, a pair of vertical columns 14, 16, and a table top 18, 20 carried
