This is your basic floor mat. For the price I got it for (50%) off I can't complain too much. But for being a guy and spend a lot of time in my chair at home doing work it shouldn't have floor dimples in a matt. Could be a little thicker. This would be a good matt for a smaller person like a kid.
So far so good but I think I would have preferred a heavier duty product. The mats are solving my problem - I no longer get my chair stuck on the carpet and my carpet is free of the dents and abuse my chair caused. I hope the mats can stand up to the wear and tear over the years. I did know I was getting an economical mat - it fit the budget and was the right size for the job.
