Enhances ergonomic positioning of your hand, wrist and arm for better support and more comfortable mouse use. This wrist rest is unique because the nonstick pads on the base allow it to glide along a desktop with the mouse to provide continuous alignment that keeps the arm at a neutral angle. Conform padding material provides soft support and the wrist rest helps reduce the risk of repetitive strain and carpal tunnel injuries. The included SmartFit size chart helps you find your personal comfort color. To ensure a proper fit, simply switch the interchangeable inserts in the wrist rest to match your color. Conform wrist rest is compatible with all mice and ambidextrous for right or left handed use.
