Works okay I guess but dents very easily. therefore sliding back and forth is really not possible. Would probably work on flat carpet but I bought it since it said it was for carpet up to 3/4" thick. This carpet is not even 1/2".
I bought this as a replacement for the previous one which cracked and failed after one year. I think the plastic dries out and then it's no good. But I needed it so I got another. One thing to beware of: the cleats on the bottom are VERY SHARP and will rip and tear your skin. Try to get someone to help you carry it. I was bleeding in several places after moving it.
I bought the chair mat to replace one that was larger and had yellowed over the years. The size is smaller which is fine for the chair that I have. The only complaint I have is that because the mat is slightly thinner than the one I replaced and so the chair wheels leave an indentation on the mat after sitting on it and sometimes a little difficult to move. Otherwise appearance and quality is fine for the price.
How could I get excited about a floor mat? But this is exactly what I ordered and I'm very happy with it. If you need a floor mat for a hard floor this will work for you.
