Arrived a day earlier than scheduled.   One box was badly damaged but headboard was okay.  Took 2 people 2 hours to put together.  Quality is good.  Looks great.  Slats are 4” apart and manufacturer had confirmed by phone that they would be 3” as is the requirement for all boxed mattresses.  Will have to purchase box spring or bunkie board for extra support.  That is why 4 not 5 stars.
