I was enormously impressed by -- of all things -- the assembly instructions.  All the parts were numbered and clearly pictured in a way that made it easy and clear to quickly see what end of what piece went where and interfaced with what end of what other piece. No time wasted with head scratching.  Also, they thoughtfully included a small ratchet wrench, rather than just an Allen wrench, which sped up the job nicely.  Also, something that I have never seen before, but really liked, was that they included "extra screws" that we ended up not needing, but the thought was really nice.  A couple of the parts were incorrectly numbered, and one part was missing its assembly numbers entirely, but it didn't matter because the images provided in the instructions were so clear.  And the end result was a bed that looks FAR nicer and FAR more sturdy than the price would suggest.  We ordered a mattress with it, and that was more plush and comfortable than we'd expected for the price.
