I am very happy with my new carpet chair mat. I had one before but after many years it finally wore out. If this one eventually wears out I will replace it with the same thing. It is the perfect size for me.
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.
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.
