Perhaps I just got a unit that slipped past QA, but the assembly on this was a nightmare.  The back of the unit didn't come with pilot holes, so I had to drill some in myself for the 10+ screws needed to fit the back on.  Putting in the drawers, for one person, was a complete PITA too.  I have put together many pieces of furniture before, and I'd have to say that I would never put a unit like this together again unless someone paid me to do it.  Total assembly time was over an hour.
