REDUCE WRIST STRESS - Our specially designed support pads are excellent for long periods of typing or internet browsing. The memory foam wrist rest conforms to the curves of your hand, helping to reduce wrist pressure that can lead to repetitive motion problems. DIMENSIONS - Keyboard Wrist Rest: 17.12 x 3.34 x 0.98 inches (approx. 43.5 x 8.5 x 2.5 cm), Mouse Wrist Rest: 9.84 x 9.05 x 0.98 inches (approx. 25 x 23 x 2.5 cm). The keyboard wrist rest fits all types of keyboards. ERGONOMIC DESIGN - Features a special wave pattern support to help alleviate wrist fatigue and relieve pain from long hours of typing. MEMORY FOAM - Memory foam molds to your hand in response to heat and pressure, evenly distributing body weight. It then returns to its original shape when pressure is removed. In addition to preventing shocks, these properties make memory foam very comfortable. NON-SLIP MATERIAL - The non-slip rubber base provides a firm grip, preventing the keyboard pads and mouse from unwanted sliding or movement. Double adhesive and hand-pressed edges ensure flat, smooth edges that won't roll or crack.
