I bought this mat for the low price to use in my home office. It is thin and meant for low pile carpet. I have a very old high/low carpet in that room and it works just fine. I think in time the chair will leave "dents" because the mat is very thin. But for the price it is a very fair value
This mat slides all over with the chair. Do not like it at all. Should have bought the more expensive one with the little tabs that dig into the rug to hold it.
