Got some floor mats from SOS a few days ago and I need some advice. They came boxed with some other goodies and were folded in order to fit in the box. They are both deformed and I'm unsure of what to do to flatten them. I tried leaving them out in the sun on a hot day for about five hours and then put a box weighing appx. 30lbs on them to no avail. Any other suggestions are welcome and greatly appreciated!
