Maintains a neutral physiological position: Bridges the height gap between the arm and the desk, preventing excessive wrist extension or lateral deviation and reducing the risk of nerve compression within the carpal tunnel.
Relieves fatigue from unsupported posture: Provides continuous support, preventing muscle soreness and stiffness caused by prolonged periods of holding the arm in mid-air.
Distributes contact pressure: Uses cushioning materials-such as memory foam or gel-to prevent direct pressure on bony prominences (like the ulnar styloid process), thereby avoiding ischemia or inflammation.
Assists with posture correction: Serves as a visual and tactile reference to remind users to maintain a proper operating posture, lowering the risk of developing "mouse hand" (carpal tunnel syndrome).
