The design of the 3M Wrist Rest was derived from medical technology: the gel from pressure relief cushions for wheelchairs and hospital beds and the fabric from medical tapes and bandages. Each material brings unique qualities to the finished product. The firm gel conforms but then quickly returns to its original shape, while the non-woven fabric is low friction, gentle to skin, highly conformable and reduces heat and moisture build-up.This height-adjustable gel pad encourages neutral wrist position. Exclusive gel filling and non-woven fabric provides soothing, comfortable support. It is available for keyboard or mouse or for keyboard and mouse.
