I bought one of these for my desk chair a few years ago and it has held up well so I bought another one when I got a new recliner so I wouldn't mess up the carpet. It was the perfect size. I cut off the "lip" or whatever it's called but in hindsight I should've left it because I have stuff around my recliner for books and things and that lip would've also protected the carpet and made it easier to clean. Oh well. Lesson learned.
The mat is saving my carpet. It makes rolling around on my movable stool much easier. It enables me to do my job which is giving Massage Therapy treatments. Love it!
This is the worst carpet chair mat. There were no identifying tags on the mat. I have a flat pile carpet I think chair kept getting stuck in the divots I would have to raise my bottom and pull the chair out of the divots to be able to move it. Retrieved my old mat and put it back with cracks and all.
