Meet the Wristocat: a wrist support device that suspends your hand and wrist with magnetic levitation, reducing stress on it as you use your mouse, keyboard, and other input devices. Just put it behind your input device and rest your palm on it.
Wristocat keeps your wrist straight and comfortable. It adapts to your every movement as you work. Wristocat is designed for coders, office workers, and anyone in between. More information is available here.
