Gas-spring riser arrives fully assembled and holds a monitor plus laptop.
Take your sit-stand setup out of the box and put it straight to work. This portable gas-spring standing desk converter arrives fully assembled, with a 31.25 x 21.25 in / 795 x 540 mm tabletop that fits a monitor up to 32 in / 81 cm and a laptop side by side.
The gas spring moves the surface between sitting and standing through a 2.16-16.14 in / 55-410 mm height range and carries up to 22 lb / 10 kg. The scratch and stain resistant tabletop stands up to daily use, and a mobile device tray keeps phones and tablets in view while you work.
MDF and steel construction keeps the riser sturdy at a portable size, and it sits on an existing desk in a home, office, or dorm — no furniture replacement required. If you would rather adjust at a button press, the SE91 portable electric standing desk converter steps up in the same family. Backed by a 1-year limited manufacturer's warranty, parts only, a 30-day RMA, and US-based phone support at +1-972-423-5015.
