[Improved Ergonomic Design]: Univo Colors wrist rest is made of premium Memory Foam fiber, which is resilient and not easy to deform. The soft, smooth and breathable technical surface material is gentle to the skin, without the abrasions and rashes that may appear on plastic and vinyl surfaces. The height and thickness of the upgraded version support your hands and wrists at the correct angle to reduce pain and fatigue caused by long-term repetitive movements [Massage Beads Enhance Comfort]: This upgraded version of the wrist rest has a new bumpy massage bead design, which fits the wrist better, avoids prolonged use of stuffiness, and is more comfortable than ordinary flat wrist rests.
