First off, let me say that anything would be better than the 4 inch futon mattress I slept on for the last 6 months. I could feel the metal bars underneath me. But even with my low expectations, I was impressed immediately upon tearing off the plastic. It was so thick, heavy and seemed fairly well made. I had to really struggle to move it on my futon frame by myself. 24 hours later it has fluffed up to 9 inches, I imagine it will fluff up another inch in the next 24 hours but even if it doesn't, I had my first good night's sleep in six months, could feel nothing but pillowy softness (but not too soft) below me. Now, futon's are notorious for being uncomfortable and my envy of those with a pillow top mattress has not been overcome, but this futon mattress is to sum it up in one word- COMFY.
