I bought this mattress almost two months ago for my futon (used as a bed) and it's great. It's firm, but not hard- it definitely molds to your body, but offers plenty of support. It doesn't seem to compact-at least not yet- but I make sure to rotate and flip it as I sleep in the same position each night. I have it in a protective dustmite cover, so I don't care about the actual color of the cover, but I remember thinking it was a disgusting color that couldn't possibly go with anyone's decor (I got the Cedar color). Plan on buying a cover if you're using it as a couch. The smell others mentioned is definitely there; it reminds me a little of cedar although that's not quite it, but it's not bothersome. It's gotten less strong over time, and it never really bothered me at all. My only complaints are that, of course, it doesn't loft up to the promised 8 inches, and it's a little short for my frame- being tall, this is a little irritating since the frame is already a little short. All in all though, a good buy and one that I hope will last for years.
