The patio sofa is a great purchase and very happy with it.  The reason for the 4 stars is because the directions were missing 2 pages.  These were the critical pages to connect the back to the sides and bottom.  With trial and error and studying the pictures on Wayfair, we guessed at how to build it.  It's not intuitive.  Probably took us about 30 minutes longer than it would have if we had the missing pages.  But it's now sturdy and beautiful on our porch,
