The mat is doing its job but it could be thicker; it bends under the rolling office chair legs and I am not sure how long it will hold before cracking thru.
The mat is about the same thickness as what I previously had. It tends to indent as I roll across it. I will have to remember to order a thicker mat next time. My last mat eventually cracked and I will be throwing it out. I don't expect much from the new one this review is on. My carpet is a short pile carpet.
