This mat is very thin and would only work on hard surfaces to prevent scraches on floor. I tried to use it over carpet and the wheels on my office chair made indentions in the mat and went thru to carpet.
We have 3/4 carpet and chair rolls fine. Minor wheel indentations but chair sinks much less than thinner mat. Only issue is that after a week of placing heavy weights around the edges they still curl up about half an inch--just enough to stub a toe or catch a wheel if it rolls off the edge.
I’m very pleased with the mat. It is certainly helping to save my laminate hardwood floor. I’d be ecstatic if it was 6 inches longer but I am very happy with it. The product descriptions were a huge help in deciding what would work best. Thank you Staples!
