The relax armrest is our most popular armrest.  This is a 2 dimensional armrest which swings from left to right and also extends in and out.  The arm can be set at different heights but once it is set, it stays level and does not bounce up and down.  This arm is typically used on the non dominant arm and is ideal for stabilizing a mirror or just stabilizing your arm to take the pressure off of the shoulders, neck, upper back, and arms. The relax armrest is also used on the dominant hand often.
