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.
The last one was very durable. I really saved the carpet under the desk. I hope this one holds up as well. It seems very "strong" & was easy enought to handle & roll in transport. It seems to fit very well. Thanks.
The chair mat is just what we needed to replace one that was 11 years old. Also it was at a fare price. I am sitting in a chair in that is on the mat in front of our computer. A smart purchase.
