The Kensington Modular Platform With SmartFit System is a great way to improve the ergonomic comfort of your workstation. The adjustable platforms allow it to fit any size desk space; use all three platforms for a large mousing area or remove one if you want to fit just your keyboard. The low-profile articulating arm features height and tilt adjustments, and can be fully rotated. The keyboard wrist rest allows for even greater comfort during extended sessions. As one of Kensington's SmartFit system products, the modular system has a color-coded window that allows you to adjust it to your unique SmartFit comfort color.
