We're very happy with this bunk bed.  It was fairly easy to put together, even with a couple mislabeled pieces.  The slats are pretty weak, so I cut some 2x4's instead.  I then bought a couple plywood boards and cut them to fit snugly on top of the 2x4's.  Now it's very sturdy and the bottom bunk is able to hold my weight (240lbs).  I'm sure this will be in our family for a long time
