Curious to see how the mat wears over time. I just bought two of them and it solves the problem of the chair wheels rubbing on my wood floor. I did not give it five stars since I have not had it long. It seems durable enough and it does not look too bad either. If it keeps my wood floor from being ruined then I recommend this product. It was reasonably priced. So far I'm happy with this product :0)
I am using this in my home office. I have it on a deeper carpet than the product recommends but it works ok. It doesn't slide and my chair rolls better on it than on the carpet. It's not the best rolling surface but I am on a tight budget and it was a great price. All of the other similar mats (or even smaller ones) were MUCH more expensive and I didn't see the need for paying so much more. This isn't the best thing since sliced bread but it works for me and my situation.
I have a 1/4" pile carpet and the casters from my desk chair sink into the mat and make it difficult to move the chair. That is precisely what I was trying to avoid by buying the mat!
