I have already 4 of these and use them for more then office use.My little dog also loves them for the noise it makes when he runs on them overall a great buy and very good quality.G.J
I replaced the previous pad because it had cracked in many places under the chair. The new pad seems thinner than the last one so I expect it will fail sooner.
Chair mat sinks into the carpet further than I thought it would so therefore it makes it difficult to move smoothly over it.... . I will replace it with another kind of chair mat. I would not recommend it for low pile carpet.
