Made from flexible, soft, and supportive memory foam. This computer keyboard wrist rest is crafted from dense foam that slowly rebounds, providing comfortable touch and long-lasting wrist support without deformation. The non-slip PU rubber backing offers reliable and unwavering support, no matter how fast you type. The advanced base remains non-slip even after washing and is widely compatible with tabletops made of glass, plastic, wood, and metal. The ergonomic shape and massage grooves provide excellent wrist support and pain relief. Unlike silicone, memory foam has slow rebound properties for superior ergonomic wrist support. Thanks to the massage hole design, you can give yourself a wrist massage anytime by simply rubbing your wrist quickly on the long keyboard wrist rest.
