This was my first mat for home use. It came rolled up but that wasn't a problem. In several moments it was straight. The only small issue I have is that it moves on the floor. Otherwise for the money it's great!!
In 6 months or less the mat will get brittle crack crumble and need to be replaced. But it is better than trying to use my chair on a rug without it. There has to be a better way to make the product last. I have purchased enough of them that I should have bought stock in the company to get rich.
