Variable height platform device

A variable height workstation system includes a base, a variable height platform, a lift mechanism, and a sensor arrangement. 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 sensor arrangement is operatively connected to the variable height platform. The sensor arrangement is configured to sense the position and movement of a user on, above and around the variable height platform for outputting data to determine how the user is positioned on, above and around the variable height platform in comparison to a predetermined target position.
