This mat is fine for what I need it for to keep my office chair running smooth and protect my rug. It is not very thick plastic so I’ll be interested to see how many years it will last but because of the price I could buy three before I would pay the price of the more expensive priced thicker mats so that’s worth it to me!
Didn't even rate the one star I gave it. This is not strong enough to roll a chair on. There are depressions in it after sitting on the chair for a while. Do not recommend this product.
