Nice product at 25% of the cost of other chair mats. I got what I paid for. It works but slides on carpet alittle. I have to re-lay it daily. It does hold up to chair pressure and does work. Annoyed that it moves but wasn't going to spend $70 just for something that claims not to move on carpet.
I bought this online but I never would have bought it if I would have seen it first. It seems much too thin and the cleats are way too shallow for even my 3/4" carpet.
