This product did not work in our home. We have a low tight pile carpet and our chair wheels are not being supported by this model chair mat. It may be sufficient for a commercial pile carpet.
I got a little more than a years usage before the mat started cracking and had to be replaced. It would be helpful if the mat was at least a quarter inch thicker.
Hoe this will be the best chair at. Previous ones normally did not last very long before they cracked / broke to pieces. This seemed to be a good value for the money and it was not folded up. It has a one year guarantee so I'll be curious to see if it indeed lasts that long. If it does it will most definitely be a first.
