Great bed for the money. I am a 63yo woman without an engineering degree and put this bed together in 35 minutes easily. I highly recommend using an allen wrench drill bit to fit the 24, yes, twenty-four, bolts that hold the frame together.  Using the short allen wrenches provided would easily add an hour to the process. I also recommend a soft mallet to pound in the plastic 'buttons' that attach the slats to the frame. a Pros: the pieces were all there, unbroken and fit together. Cons: this is not a bed that could be taken apart easily for frequent moves. The slats attach with plastic compression "pegs" and will not stand being pulled out of the frame.
