Assembly took less than an hour and was very simple.  The frame is very sturdy.  The only reason for 4 stars is the size of the wood posts on the ends are underwhelming and make the proportions seem off for a King Size frame but other than that it is a very nice bed frame.  I love that it's open and you can see through it.  It makes my very small bedroom appear to be much larger.  This is exactly what I was looking for to achieve my farm house bedroom.  We are in the process of painting so these are not the greatest pictures.
