This is a good size for my space but it slides around on the carpet so I have to constantly reposition it. It claims it is for high pile carpet but the "spikes" on the underside are barely more than small bumps and serve absolutely no purpose. I also have issues with the wheels on my chair getting stuck in the slight indentations (the material is not thick/hard enough). I will keep it because I do not want to hassle with getting it back to a store for a return but I definitely would not purchase again nor would I recommend it to anyone else.
what can i say -- its a chair mat. now my chair does not dig holes in my carpet and glides aroud nicely. i suppose good quality -- but it says for high pile but my carpet is thicker that this mat allows for. anyway its a good mat.
