As it is thin chair wheels sink in at take a "set " which can make it initially hard to roll the chair. I suspect this will lead to it breaking down (they all do) faster needing earlier replacement. It is a nice size. The thicker (and more expensive) ones were much bigger.
I'm using the chair mats in my sewing room which has berber carpet. I'm hoping these will hold up better than ones I've purchased in the past. The old ones cracked and chunks broke out of them after just a few months of use. These are really smooth and easy to clean and chairs roll really nice on them.
The product is ok but all the floor mats seem to be the same standard size... I could use a larger one and putting two together just jams up the rollers on the chair when I try to move over the gap. Maybe because it's on carpet but then again if it were just another three feet longer it would be no problem.
This product is literally saving my wood floors from damage by my desk chair. The chair rolls easilly over it's surface and the mat feels good under foot. The size accommodates the rolling area of the chair perfectly. The only thing that I would wish to change about the product would be if it was clear rather than somewhat opaque. I would like to see through to my wood floor beneath. But I do not know if such a mat can be made and still retain the positive features mentioned above if it was clear and not opaque.
