SmartMotion's Forearm Tray gives its owners the opportunity to rest their forearms while typing. It clamps on to the desk, providing a seven-degree angle on which to rest one’s arms. This alleviates tension from the hands through the upper body.
The tray requires a 27" opening under the desk to clamp it on. Also, it requires a desk area less than two inches thick to apply the clamps.
For those who sit close to their desk, do a great deal of typing and need the forearm support this provides it is an excellent tool.
