With a simple push of a button, you have the flexibility to sit or stand and effortlessly adjust from one to the other at a rate of 1.2” per second, while a programmable keypad remembers your favorite positions. It comes with furniture feet. Locking casters are sold separately to add mobility and/or increase the overall height by two inches. The sturdy desktop - with a 220-pound weight capacity - can easily support solid-wood desktops, plus your computer and monitors, heavier equipment, paperwork, and more. An anti-collision mechanism prevents you from accidentally lowering the desk on top of objects underneath or raising it into objects above. A wide selection of Stand Up Desk Store accessories, which include a pencil drawer, privacy panel, keyboard and/or mouse tray, monitor mounts and monitors stands, plus cord and power management, let you fully customize your adjustable height desk for optimum productivity.
