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.
