The Computer Arm Rest is a great addition for keyboard use as well. Two units can be installed one on each side of the keyboard to give complete support to forearms.
The weight of the forearm is distributed over a large area. This reduces localized pressure on the wrist and eliminates the constant strain on muscles in the neck, arms and shoulders that so many computer users experience. Behind its simplicity, the pad hides a few useful tricks. It can be adjusted to the desired position and while the forearm is placed on top of the padlocks itself in place.
It allows for stability when using a mouse. When not in use it can be turned completely sideways allowing an easy access to the chair. An interesting feature of the pad is that the pad can be easily lifted and completely removed.
