ARMSTSL transforms a desktop into a standing desk

Adjust the height with one smooth motion

Moving between sitting and standing throughout your work day brings many health benefits, from increased circulation to reduced fatigue. The sit-stand workstation makes it easy to change your position throughout the day.

Change the height of your work surface, effortlessly, with a full 22" (560 mm) of vertical extension. You simply squeeze the lever at the side, and then move the workstation up or down smoothly, using pneumatic technology. Its straight up-and-down movement saves space and provides a stable platform as it moves, with no fear of tipping. 

Plus, there are no preset levels, so you can find the precise height you need to work most comfortably. It also offers a counterbalance feature, so you can adjust the tension according to the weight of your monitors, to raise or lower the work surface with ease.

ARMSTSL is sized to fit easily on your desktop

Sized to fit your needs

The sit-stand workstation is conveniently sized for easy integration into your workspace. It’s large enough (35.4” wide) to hold two 24” monitors, yet small enough to fit on most desks or other surfaces. Whether you work in an office setting, cubicle, or home office, the sit-stand workstation sits easily on your desk or work surface, and even works well for corner desks. It works well on a variety of surfaces that are 24” or deeper. The work surface supports a weight capacity of 28.1 lb. (12.7 kg).

The desktop workstation also features a large keyboard tray, with plenty of room for personal items like your phone.

Easy setup

The sit-stand desktop workstation comes fully assembled so you’ll be up and running quickly. It also includes cable management to keep your cables organized and out of sight.

The ARMSTSL is backed by a StarTech.com 2-year warranty and free lifetime technical support.
