This mat for under my desk chair is incredible and necessary to keep me productive at my laptop. An excellent way to help save the rug as well. I would recommend this to anyone who has a floor or floor covering which they seek to keep in good condition.
I've only had the Low Pile Carpet Chair Mat Lip by Quill Brand for a few weeks but so far it works pretty well. I've had difficulty in the past with chair mats because my carpet is a bit thicker and the mats seem to crack and fall apart. We'll see if this one holds up.
