A 31.5 by 15.7 inch desktop riser with pneumatic lift from 4.5 to 20 inches holds dual monitors up to 33 lbs and a syncing keyboard tray up to 4.4 lbs
This VIVO desk riser converts an existing desk into a sit-stand workstation with a 4.5 to 20 inch height range. The single pneumatic spring lifts the 31.5 by 15.7 inch top surface straight up so dual monitors or a laptop combination stay level. A synchronized keyboard tray measuring 31.3 by 11.8 inches rises with the desktop for ergonomic typing posture.
The grey steel frame supports 33 lbs on the desktop and 4.4 lbs on the removable keyboard tray whose centre section narrows to 10.5 inches. Base dimensions of 30 by 16 inches keep the footprint compact while the lift mechanism operates with a simple squeeze handle. No external power is required and the tray can be removed instantly when extra clearance is needed.
The patented lift-assist mechanism maintains smooth motion through repeated sit-stand cycles without motor wear or electrical failure. Steel construction resists scratches and holds the rated 33 lb desktop load continuously during long work sessions. The manual pneumatic spring delivers consistent force across the full 4.5 to 20 inch range so the workstation height stays stable once locked.

Attach the keyboard tray brackets to the main frame using the supplied bolts, then secure the gas-spring cylinder; the step most people miss is tightening the cylinder lock-nut before the first lift, otherwise the 4.5 to 20 inch range will not hold position.
The single pneumatic spring is the only wear item; after thousands of cycles it can lose pressure, causing the 33 lb desktop to drift downward.
The spring is rated for 33 lbs on the top surface and 4.4 lbs on the keyboard tray; exceeding either limit makes the 4.5 to 20 inch adjustment stiff or uneven.
