I purchased this chairmat because it is just the right thickness and durable. I had one before and it is holding up well . I needed another for my husband's computer. It rolls over easily and didn't crack.
I've had this item in my house for a week. It still has bumps that have not flattened. I also have it on carpet. The little teeth on the bottom do not stay in the carpet. My chair is on wheels and I've had to move the mat every 2 days to put it back in place. Because it moves the chair wheels get stuck if I move forward too much I can't get the chair to roll back.
I had gone to the store in person to shop for mats and couldn't find what I needed then decided to shop online and found exactly what I wanted. Easy from start to finish. Thank you!
It has been in place only a few days but I find mat dimples just with the unburdened weight of a wood desk chair. Mat is workable but I believe mat of soft material. Mat sits on very low pile Berber rug.
