I was a little up set. This pad slides on carpet and I have to keep pulling it back. We purchaser 2 chairs two days apart The first one was wonderful that is why we went back for the other. This chair squeaks it is uncomfortable it sounds like it is going to break. One of the wheels was broke so we had to get another one I don't want to have to go thru that again.
I am 200 lbs and have a five roller desk chair on mid pile carpeting. My last desk mat started cracking after 2 months and I threw it away after 4 months. This new mat is thicker and heavier than the others I have seen and has not cracked in the month I have had it. I hope it lasts.
