I believe other posters said to install the bottom cushions first, and I could not agree more! So much easier!
Only 4 stars because some of the bolts did not sit level when I screwed them in, and one of the bottom cushions the wooden hole broke so I couldnt get the screw to stay in. I was a little bit distracted so start to finish was about 3 hours to assemble by myself. 
Love the adjustable feet on the bottom of every piece to even the chair out. The seat cushions are a little too firm, but this is for our eat-in kitchen so I dont anticipate sitting there for long periods of time.
