The chairmat is adequate for the job. It is not as thick as it could be so my office chair wheels have made permanent grooves where they sit. I don't find it easy to roll on and I thought it was expensive for what I got. I didn't want to pay anymore money so I got the cheapest one they had.
I have bought the old ones you sold but over time you have made them cheaper and less thick . I would have brought it back as junk but I cannot find the receipt. I am goinh to [...] and grt a piece of hardboard..
I can't really say anything about this product because I haven't had it very long. the last time I bought this product was five years ago. I have berber carpet and a light weight office chair. at this time it seems ok.
