This desk converter works out of the box on top of your existing desk. The powerful electric motor adjusts the height from 6" up to 19.25." The spacious tabletop measures 48.5," and the keyboard tray measures 35.5" across so you can use the keyboard and mouse side-by-side, two monitors, a laptop, a tablet, and more. Increase your efficiency by adding a dual monitor mount to this desk to free up even more space.
