This mat is doing everything I need it to do. It’s on gym flooring that’s on Hardwood floor. It doesn’t crease or crack under my chair on wheels, I move smoothly over it. I can roll my under desk treadmill over it easily so I can go from sitting to walking seamlessly. It came flat so I didn’t have to unroll it or deal with curled up edges, and it does not smell (as so many reviews of similar products complained about!)
