Being productive and healthy at work can be tough but beneficial! With our S5 manually adjustable desk frames, you can attach your own desktop surface and use the hand crank to raise your desktop from 27 to 46-inches tall. The ultra-quiet system will not disturb other people, and is easy to adjust. A power source not required, so you can place it anywhere in the office or home without taking up an outlet. The frame expands from 43 to 63-inches long, but make sure to measure your own desktop surface to ensure a proper fit— desktop surface not included. We carry a full line of standing desks, standing desk frames, desk surfaces, and desk risers to set on top of a regular desk, as well as a wide variety of fitness products.
