I am very happy with this sofa sleeper, but know a couple of things going in.\r\n1. Rumors of this sleeper being VERY firm are NOT exaggerated. I was hopeful that they were, but this sleeper is very firm (hard?!). But I was prepared after reading reviews to have to add a topper, which I have, and it has worked out great. We won't be using this as a sleeper regularly, so this is not a deal breaker for us. If you need to open and close this regularly, adding a topper may be a pain.\r\n2. The good news is, assembly is pretty easy. Really you only need to add the arms, which we did easily by laying it on its side, sliding the arms on, and flipping it and using the weight of the thing to firmly secure the arms. The bad news is, it is really heavy! I have stairs up to my house, and they only sent one delivery guy, who left it at the bottom of the stairs (with my help to get it up the curb!) not even on my porch. I had to wait for my husband to get home. We unboxed it and painstakingly brought it up using those "magic" straps. Fortunately it did not rain, but have a tarp handy or two very strong people to immediately take it inside! Or better yet, I think that you can pay extra and have it brought to a room of your choice. It is not hard after that, but definitely takes two.\r\nI really love the layout of the sleeper. I have tall guests and many sleepers have obstructions for taller people, or flimsy mattresses and cost much more. I think the firm mattress here will be good in the long run. I do not want a flimsy mushy sofa, since that is mostly how we will be using it.\r\n\r\nAlso, someone mentioned that the head part goes down lower than the rest of the bed (See my pics) but we did not find it annoying using a regular pillow. And finally, as someone else noted, the box is flimsy and arrived banged up, but it was packaged well and not damaged.
