ERGONOMIC COMFORT: Give your body and mind a break from sedentary work with the push of a button. Bush Business Furniture's Move 40 Electric Height Adjustable Standing Desk is a perfect way to build an ergonomic workspace without the high-end price tag. EFFORTLESS ADJUSTABILITY: Three stage units lift the 48W x 24D sit-stand desk anywhere from 28 to 48 inches at a speed of 1.25 inches per second. Four programmable presets save your favorite heights so you can change positions without missing a beat. SEAMLESS INTEGRATION: A variety of finishes with a black or silver base allow you to choose the perfect look for your workplace. The electric desk plugs into a standard outlet so it can be used in any setting, from an open floor plan to a private office. BUILT TO LAST: The ergonomic desk's thermally fused laminate work surface resists cosmetic damage like scratches and stains to endure years of use in a busy professional setting. A welded 16-gauge steel base allows the desktop to support up to 176 pounds. TESTING AND WARRANTY: This height adjustable desk has been rigorously tested to meet or exceed ANSI/BIFMA quality standards for safety, durability, and performance and is backed by the Bush Business Furniture 5 Year Manufacturer's Warranty.
