Just wanted to mention that the problem of removing the labels which is mentioned in the reviews for just about every chair mat I looked at seems to have been fixed now (July 2014). We ordered 2 and both labels came off easily. Seems like Staples at least paid attention to the comments. As far as this particular product we are pleased. It seems sturdy and of appropriate thickness/strength. It arrived flat. The little cleats on the down side that keep it from moving around on our previous model were sharp and murderous - very hard to handle the mat without getting numerous stabby pokes. On this particular model the cleats are less sharp and it was easy to wrestle the mat to its destination without personal injury. Much appreciated!
The mat seems to do what is supposed to do. I do see some dimples the chair has made on this mat not sure what the longevity of it will be time will tell
The carpet mat is great and makes rolling a lot easier. It also helps the wheels roll and not get stuck. I was told the carpet mat keeps the wheels from getting stuck on the carpet and keeps the wheels from breaking. I am very happy that the chair rolls the wheels don't break and the carpet is protected.
