We have tried for 2 months to get this mat to lay flat with no luck. We’ve put heavy objects on it and everything. Now we have to buy a new mat as this one is unusable.
I believe the label on the mat said for medium carpet which is what I had. But my chair wheels would immediately put a visible dent in the pad and prevent the chair from easily rolling around. Maybe this pad would work on a hard surface floor but I can't imagine any scenario where it would work on carpet.
