Great quality.  As others wrote in their reviews instructions can be a bit better.  I am in construction and did assemble the bed in about 3 hours.  The issue is that there are about 5 different instruction manuals.  You will have to find them all in different boxes and figure out on you own what to build first.  Overall I am happy with the bed.  Rated that each bed can hold 750 lbs and I believe it.  My wife, 3 kids and I tested it and bed seamed very solid, like we were not even on.  All 5 of us are about 550 lbs, but you get the point.
