Just placed it on the carpet last week to replace one that I had for many years... This new one is a good size but it looks like it may not be as thick as I would have hoped. On that note I am concerned how long it will last. Just the weight of the chair and not a very heavy chair has caused dents in the mat...let's see what happens when I sit my chair and use the mat.
The carpet under my chair had to be cleaned constantly due to the rolling of the chair. The Staples Carpet Chair Mat solved my problem. The carpet is clean and the chair rolls so much easier. Fantastic buy.
