You just bought the new office chair you've been wanting. Congratulations! It will provide you with years comfort. But don't forget about a Chair Mat. Chair Mats protect floors or carpeting from undue wear and unsightly caster marks, not to mention the occasional coffee spills. They also make it effortless to shift around your workspace. Instead of skootching around, now you can glide around. Once you have one, you'll never want to be without it.
