I’ve had this about 2 1/2 months and it has already cracked in 3 places. Has divots where the wheels of my chair sit so my chair no longer rolls along the top.
I never expected such a change with getting a Chair Mat. This one is wonderful. I have ample room to get in and out of my chair and slide under my desk. It grips the carpet just right and has not dented as I have heard in some reviews. There is a tiny marking but it has no bearing. It came flat which was a great relief from what I have heard could have happened. I highly recommend this Chair Mat.
