Beautiful design, but a horror for one person to put together!  It took me all day with lots of sweat and aching muscles.  There were more than enough parts in one or two envelopes and not enough in one critical envelope.  Toward the end, I didn't care if anything matched or not, but once everything was mostly in place, I loaded the mattress and it was wonderful.  If this was my design, I would put the little "lips" or "tabs" that keep the mattress on the platform at the head and foot of the platform rather than in the middle, which rubs my legs when I start to get off of the bed.  Uncomfy!  I was not able to adjust the tips at the end of the slats so they would match the holes in the rails.  (Easier to show than to explain).  Some of the screws don't match the threads in the receiving holes.  Not enough screws in the "E" bag.  Once I was as done as I was going to get, and the bed made, it was lovely.
