I needed new mat and this seemed the right one. However when I put my chair on it and tried to roll in to reach my foot pedal I felt the chair was going to put a hole in it since it was thinner then what I found out I should have bought.
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!
