Viscoelastic memory foam is renowned for cradling the contours of your body. Mouse Wrist Pillow® provides a large resting space with maximum support for your wrist at the computer to promote neutral, ergonomic positioning and relieve discomfort. Memory foam is temperature- and pressure-sensitive and also hypoallergenic so as not to irritate the skin. LYCRA® covering keeps the wrist rest soft over time by repelling sweat and dirt. The black mousing platform on this item is non-glossy to ensure best performance with optical mice.
