. Feature: Made of high-quality material, durable, firm and stable for us to use. It can be easily attached to a computer desk. 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 the pad locks itself in place. The armrest is extremely portable and installs simply and quickly. It can be disassembled in seconds and can easily be carried in a briefcase or computer bag.
