Used a few times for camping. I don't think there are any stains or scratches, but there is some smoke odor. It will be shipped in a plastic bag, so please be aware of this. Wrinkles should not be a concern if you inflate it with air, but Since it is a used item, please refrain from purchasing if you are sensitive to such things.
