After doing extensive futon/transitional couch research, I decided to trust all the good reviews and get this futon. It has exceeded our expectations! The frame wasn't difficult to put together, two people got it done in about an hour or so. We were a initially concerned that the mattress would be flat since it came so tightly rolled up, but man, does it plump up once you free it from it's plastic wrap! It definitely is a fully reinforced, spring mattress...and very comfortable! Finally, we have a guest bed we don't have to use a million pads and comforters to make sleepable. My ONLY gripe is that the frame is a bit difficult to transition up and down with only one person. But other than that, we're extremely happy with it!
