Go from sitting to standing, with one smooth motion

With a simple squeeze of a paddle, you can easily switch your position to sitting or standing, to keep a balanced level of movement. The workstation features a pneumatic spring arm that provides effortless movement - you simply raise or lower the platform with one squeeze of the lever. You can adjust the standing desk to match your exact height requirements, with a height adjustment range of 15.7" (399 mm).
