The design creates valuable extra space by allowing you to position your mouse conveniently under the desk shelf. Key Features: 360° Rotating Wrist Rest: The fashionable mouse pad wrist support features a smooth 360-degree rotation. It is engineered to elevate your wrist to an optimal height, reducing strain.

Durable & Adjustable Construction: Built with a robust combination of metal carbon steel and ABS materials, complemented by memory foam padding, this wrist rest tray ensures long-lasting durability and comfort.

Ergonomic Positioning: By lowering the mouse to the height of your chair's armrest, this support tray promotes a more natural arm and wrist posture, significantly improving overall computing comfort. Note: The red lubricant present in the platform hole is an environmentally friendly substance applied to minimize friction between the clip and the platform, ensuring smooth adjustment and operation.
