I'd give this a 4.5 if I could.  I really love the bed.  It's much more attractive than I thought it would be.  Assembly was straight forward and I managed it by myself.  The only problem was connecting the head and footboards to the side rails.  The hex wrenches included didn't fit.  Luckily, I have my own tools and was able to put it all together.    I previously thought that the bed platform was only to raise the mattress.  Little did I know that this platform actually makes the mattress so much more comfortable.  The slats include a bit of a spring once assembled and it gives the mattress just the right amount of additional softness.  I'm a fan.
