it works but it already has an indentation after 2 weeks of using it. All chairmats are over priced but at least with this one you can protect the carpet and not spend too much
I've started replacing all of our chair mats with this one because it can handle the weight and constant pressure from even the heaviest user. We bought the thinner and less expensive chair mats that were made for the type of carpet in our office and they would crack and crumble within weeks especially for the bigger men in the office. I've purchased 7 of these and haven't had any complaints since I bought the first one almost 2 years ago. The initial cost seems high but I am no longer replacing the same chair mats every couple of months.
