good if you sleep alone, Terrible if you don't! It sways too much. You feel every movement or motion your partner (or little kids) make. The frame is not solid in the sense that it will not move. The type of mattress on top does not make a difference in the motion. It is easy to put together it is a nice simple design; that allows for lots of storage, but it does not provide the adequate structure as a bed -what it's designed for- I'm putting my mattress on the floor.. it's like sleeping on a train going over terrain, not solid.
