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
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.
The mats I purchased are much thicker than previous ones we purchased. Hopefully won't crack like previous ones. Remember look for the thickness of mats before choosing by price!
