It's just okay.  A couple of slats pulled off the fabric belts when putting the heavy, awkward king mattress on.  Then a few days after assembly, a knob on the footboard broke when my 13 year old grabbed onto it.  It now rattles and wobbles.  Overall it wasn't difficult to assemble, took under an hour with two people.  It's not super solid, but it's sturdy enough, no noises when moving around in bed.  I'm happy enough with it for now, but I don't think it will stand the test of time in the long run.
