A monitor arm is a device used to hold a computer monitor and attach it to a table or wall. Allows the user to adjust the height, angle and distance of the monitor for optimum viewing comfort and ergonomics. A monitor arm typically consists of a base that attaches to a desk or wall, an arm that extends outward, and a mounting plate that attaches to the monitor. Monitor arms are a favorite of those who spend long hours in front of a computer and want to reduce stress on their neck, shoulders and back. They are also useful for saving desk space and creating a more organized and tidy workspace.
