I don't think it is going to last very long. It is too flexible to withstand the weight of a 195 pound person without the chair casters leaving a deep impression. It will eventually crack and splinter and chunks will pop out and it will then have to be replaced again...just like the last one.
What a waste. I ordered this to allow my desk chair to move easier around my office space. What I got was a patch of plastic that is worse for chair rollers than the carpet. Way too soft for using a chair. They should market this as a large clear yoga mat maybe then it'd be accurate.
It was flat when I bought it so that made it very easy to lay on the floor. It has stayed flat and has not curled like previous mats. This is an excellent mat.
