This innovative desk provides accessibility with the luxury of a very generous surface area. An easy-to-turn hand crank raises and lowers the height of the work surface, providing a wide range of heights appropriate for wheelchair users (from 27 - 39 inches). This desk provides excellent knee clearance and a surface area so large it can easily accommodate multiple computer monitors and a printer. Please specify whether you'd like the return (the desk's shorter segment) to your right or left. Two-Year Warranty.
