Bought this on sale for $399 from Staples, and it has helped my posture and back pain immensely! Offering 50% off of what I got it for. Recently got an extra monitor for my computer so I had to get a wider desk. Adjustable to your height, easy to move (has wheels), and in perfect condition. The ability to work standing up for part of the day has changed my life! Highly recommend trying these out.
