So far so good. Haha. Really easy to put together, if you follow directions and look at the photos. Last two directions should be a two person job, but it can be done by one. I did it myself  Mattress is firm and heavy. I got a queen size. Make sure you have the top side up, so the futon can fold the mattress. There’s a sticker on it to help. Haven’t tried sleeping on it yet. Tried opening and closing the bed a few times. I would suggest two people because of weight of mattress. On the queen size model the back of futon is lager than the seat (as photo shows). Wasn’t expecting it to be so much larger. So far I am very happy with my purchase!
