The MouseBean® Hand Rest is designed to provide support, protection and comfort when using a mouse. Following detailed research into the causes of mouse-induced wrist pain, the MouseBean® Hand Rest tackles the problem by applying sound ergonomic principles, stylish product design and engineering.The MouseBean® Hand Rest elevates the forearm to maintain a straight wrist. This reduces stress on the tendons where they run through the carpal tunnel. Overuse of the hand and fingers when the wrist is bent can lead to tenosynovitis (inflammation of the covering of the tendons), a painful condition affecting the forearm. Resting the forearm on the desktop can become increasingly uncomfortable.
