I bought this for the primary bed at my boyfriends house. It was nice to have something thicker than the old futon mattress he had, but I also ordered the 10 inch, gave it a "week to expand from packaging" like the box said, and turns out it is only an 8-inch. So check it when you recieve it if you pay for extra thickness. It's average, nothing i would rave about but it would be good for a guest futon mattress. I would definitely order something more supporting though if i were to do it over again...it's VERY soft.
