The main unit has scratches on the surface, noticeable when held up to the light. I used it under a futon from last June, but I'm selling it because I need to use it with multiple people. The C-type mat is unused. I personally think it's in good condition, but it is a used item, so please be aware of this and consider purchasing it.
