even with a low pile carpet this mat buckles and doesn't stay flat due to the weight of my chair. Not only is the mat now warped and unreturnable it was actually easier to push my chair over the carpet then the mat.
I was looking for a smaller mat and the size of this is what I wanted but I do find it to be very thin (compared to others) and the office chair doesn't roll as freely on it as some of the other thicker ones. But it's working out ok.
This chair pad is the thinnest I have owned chair wheels sink into the plastic which makes my chair hard to move and the mat moves on my carpet. I have never had that happen before. I will have to buy a new pad of much better quality. I would not recommend it to others.
The first chair pad/mat was not thick enough nor did it have deep enough teeth for my carpet. I was able to return it for a full refund and the store ordered the better one which was delivered to my home. It is perfect! My desk chair rolls around on it just fine and it does not move on the carpet. Great product!
