A wrist rest is a supportive cushion designed to help maintain a comfortable position for the wrists while typing or using a mouse. Typically made from materials like foam, gel, or memory foam, wrist rests can reduce strain and fatigue during long periods of computer use. They are often placed in front of a keyboard or mouse to provide a stable surface for the wrists. Using a wrist rest can promote better ergonomics, which is important for preventing repetitive strain injuries such as carpal tunnel syndrome. Many people find that wrist rests improve their overall comfort and productivity while working at a computer.
