Bush Business Furniture's Move 40 Height Adjustable Standing Desk is a perfect way to build an ergonomic workspace without the high-end price tag. Give your body and mind a break from sedentary work and enjoy a healthier, more productive office with the push of a button. Three stage units lift the 48W x 24D desktop anywhere from 28 to 48 inches at a speed of 1.25 inches per second so you can change positions without missing a beat. The Adjustable Desk also features an Anti-Collision Sensor that stops movement up or down if an object is detected. Available in your choice of five finishes, the durable thermally fused laminate work surface resists scratches and stains while a welded 16 gauge steel base allows the desktop to support up to 176 pounds. This Sit-Stand Desk is tested to meet ANSI/BIFMA standards for safety and performance and is backed by a 5 Year Manufacturer's Warranty.
