Very high quality; very strong (I weigh north of 240, and there is no flex in either the primary or trundle bed); straight forward assembly process; All parts present and fit exactly, and good step by step instructions.
Two hints, though: 1 - Don't try to assemble with the small hex head wrench they provide -- get an inexpensive tool set (Home Depot or Loews) that includes a hand held driver and the hex head driver bits; 2- (VERY IMPORTANT) - The slats for both beds are metal and they "clip in" between the side rails, and then you insert "holders" that keep them permanently in place. DO NOT FULLY TIGHTEN THE RAILS UNTIL YOU HAVE THEM ALL INSERTED AND LOCKED IN. Otherwise you may bust something, and it may be your finger!! They snap in very easily, setting the holding clips is also easy, and THEN tighten the whole bed up.
