It is perfect on our carpet. It seems to have a little give to it which is nice. It also stays in place so I am not constantly down on my knees fixing it.
The only problem with the chair mat is that my chair will leave indentations because the carpet is too thick; my computer is in the living room; our house is completely carpeted a heavier dense loop carpet. I couldn't find a mat that would cover that type.
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.
