The char mat is working fine thus far. I have had it for about 2-3 weeks. There is a 1 year warranty so I expect it to last at least that long. I see no reason why it would not last at least a year. It seems thick enough
Mat is good but getting it unrolled and laid was difficult. Too bad it is shipped rolled. The other mat I ordered previously for Berber carpets was delivered by a Staples driver and it was unrolled and was much easier to deal with.
My office chair sinks into the mat so the mat is not as firm as I expected. I bought it because of the shape and size that would fit into my office and desk.
