When I originally read the description I could of swore it said 6" of foam, with memory foam on top. It was really more like 4" with the smallest amount of memory foam. I didn't sleep in it, but my friend did and he said it was decent, but I did also put a folded king sized down mattress pad on it. He also said it was super narrow; he actually rolled off it a couple times. I thought it would have been a little bigger than it was. Assembly was pretty easy, except for one of the wooden slats was already cracked when I opened it, and another had bird poop on it randomly. I'll probably end up using the pad when camping. If I decide to get another one, it'll be at least a full size, sit higher, and have a better mattress.
