Came well packaged and I was able to assemble it in maybe 15 minutes max.  I was most impressed with the ratchet tool they provided which made the assembly go so much faster.  Note, the box is very heavy and you'll likely need two people to move it or some sort of hand truck.  Also, one of the joints of assembly was very snug and I had to use a rubber mallet to connect the two pieces.  If you don't have a rubber mallet, you can use a towel and something like a hammer.  Altogether, the bed is super high quality and very very nice looking!
