A stable lifting structure of a lifting desk contains: a first tube and a second tube movably fitted with the first tube so as to form a movable desk leg. The first tube includes a base, and the second tube includes a limitation sleeve. A movable cylinder is accommodated in the movable desk leg so that a body of the movable cylinder is locked on the first tube, and a column of the movable cylinder is connected on the second tube and is driven to expend or retract by an abutting plate and a pull cable. The first tube includes a slidable sleeve, and an inner diameter of the slidable sleeve corresponds to an outer diameter of the second tube. The slidable sleeve includes multiple recesses, a roll peg is accommodated in each recess, and each roll peg partially exposes outside the second tube via each recess.

A height adjustment system includes a first controller to control a first drive assembly of an adjustable desk frame and a second controller to control a second drive assembly of an adjustable monitor mount. The first controller is communicatively coupled to the second controller to synchronize activation of the first controller and the second controller such that an adjustment of a height of the desk frame causes a corresponding adjustment of a viewing height of the monitor mount and an adjustment of the viewing height of the monitor mount causes a corresponding adjustment of the height of the desk.

An apparatus for positioning an electronic display is described. The apparatus can be combined with an existing work surface to provide a multi-position workstation. In some cases, the apparatus includes a mounting portion configured to support an electronic display and a keyboard. The mounting portion may be movable with respect to the work surface between multiple positions, including for example, a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.

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.
