Title: what a backache!
Review: Maybe I just got a "lemon" but after a couple weeks, this futon was very flat in the middle where I slept, so that I could feel the my frame's wooden slats underneath. The sides were still fluffy, so it was very concave and I ended up with a backache... I tried flipping it, etc., but it was hopeless so I went back to the old futon that this was meant to replace.
