When looking at chairs, keep in mind that armrests should only used while reading or resting between typing sessions, not while actually typing or using your mouse.  If you do decide to purchase a chair with armrests, make sure that they're adjustable, broad, cushioned, and comfortable. While sitting, you should be able to independently adjust the height of the armrests and move them closer together or further apart. Be sure that the armrests are short enough to allow you to get in close enough to the keyboard and mouse and don't hit the front edge of the desk. Some chairs offer the added convenience of being able to easily move the arms out of the way when they're not being used.

If your existing armrests are hard and unforgiving, an easy fix is to add the comfort of soft cushioned Gel Armrest Covers for instant relief.
