Abstract
A variable height desktop workstation system that includes a base, a variable height platform, a lift mechanism, and a secondary force assist device is provided. The lift mechanism is configured to move the variable height platform within a range of motion between a fully lowered position and a raised position. The lift mechanism comprises a plurality of articulated members and has a lower raising force leverage in a lower part of the range of motion and a higher raising force leverage in an upper part of the range of motion. The secondary force assist device is configured to provide an additional force to the lift mechanism directed to the variable height platform in an upward direction from the fully lowered position towards the raised position only in the lower part of the range of motion so as to compensate for the lower raising force leverage of the lift mechanism.
