This is a wonderful piece that will let my office double as a guest room. The assembly instructions were clear and all of the parts were in the box and undamaged. The bed was easy to assemble. I assembled the piece by myself, but it would be easier with 2 people. One person can unfold the bed and it closes easily. The mattress is remarkably comfortable! The bed comes in 3 pieces: the main cabinet, the base and the rolling drawer. The main cabinet is quite heavy.  I would recommend that you pay to have it delivered to the room where the bed will be. I also recommend that you place a teflon slider under each of the adjustment screw feet, especially on carpet. If you ever need to pull the whole unit away from the wall, this will make it a lot easier.
