give this mat 3 stars its ok not very durable over carpet chair likes to sink in on the mat have to pull yourself to get out of your sink hole.....but overall nice mat.
Does not work on carpet up to 3/4" thick as advertised. Product is too soft and my chair leaves imprints. Additionally it will not stay in place. Had it 2 days and decided to order a polycarbonate pad from a different vendor.
My previous one of this model lasted ten years before the plastic began to harden and break apart under the usual spot where the wheels were which was pretty good value.The chair rolls easily.
Perfect size for my space. The pad material is turning out to be softer than I hoped because the casters are leaving imprints. The chair rolls very nicely on the pad and I needed that on my carpet.
Too early to tell but it is already showing depressions from the weight of the chair (and me) resting on it. I don't remember that on the one it replaced which I had for over ten years.
