Mat is too thin too soft and does not have beveled edges. It is of much lower quality than the previous one I bought at Staples. Chair sits in depressions and will not roll around easily.
I really appreciate that this product was delivered quickly and was delivered FLAT not rolled up. When they are rilled up it can be a pain to get them relax flat on the floor.
Did not work on my commercial carpet with no pad. The bumps that go against the carpet were too large. When I rolled on the mat it was similar to rolling on a cobblestone road. Took it back. Very disappointing. Recommend you carefully consider the thickness of your carpet.
