The chair mat is exactly what I was looking for. It is heavy enough to stay in place and my chair rolls smoothly. I recommend it to anyone that wants to protect their carpet.
My mat was and is great. The only thing I want to mention the delivery came a day early (no problem here). However the delivery man ignored the large sign at our front entrance which we DO NOT USE and left the mat there anyway. I caught him before he left and showed him the sign asking anyone to STOP - PLEASE DELIVER ANY PACKAGES TO OTHER SIDE OF HOME. He did speak English but was clearly not from the U.S. Just wanted to let you know. Otherwise everything was great.
Good value. Chair mat was shipped flat not rolled up as other reviewers fought with. The shipping label peeled off cleanly. Relieved be using it right away.
This mat won't unroll and was rolled up with the carpet spikes on the outside. So I ripped my hand open trying to just unroll it and now a week later it still won't lay flat. Put a heat gun to it today to try to get it to lay flat with little luck. More than likely I will have replace it and just throw this one away.
I saw several reviews that said their mat was rolled up in a box. Ours was delivered flat with no box. It was only a little bent because the delivery person left it leaning on a wall and was easy to flatten it out again. It's worked great so far.
