Disappointed after set up this bed. It looks very good, but sleeps lousy. The screw design is awkward, I can not imaging those engineers design such terrible connections. Furthermore, several screws' male and female are not workable. You can imaging I was shouting and cursing when I set up this terrible bed. Each time when I turn, it makes noises. American customers are really on weak side. Spending of $300-400 should really give you a sturdy and luxious   bed in Asia countries.
Sigh!
