excellent bed. Seems sturdy and like the the stairs as opposed to a ladder. 
Instructions were very good. However a couple of pieces weren't mark right. Not a big deal as you could tell from the picture the right number. Hardware sorted good. No extra wood dolls so be careful not to break them.  Installed by myself, did need my wife to left twin on top but that was it. Took about 4hours to complete.  Overall very satisfied.
