Well, it would seem as though one of the 4 back pieces is out of place...I noticed it first thing, and with the way my deck is set up, it’s the first thing I see when I walk out. Also, I understand that it is a foldable chair, but there is a lot of give to it.  When you get it or out, the two main pieces move an inch or so..and you notice it. I’ve tightened things up, but...nothing changes. 
On the positive side, it came earlier than expected, straightforward instructions and when you look at the chair from the front or back, it looks great. But, again, you look at it from the side..and you see the piece out of place. Honestly , the photo doesn’t do it justice. I can see it from my dining room table...actually, the more I see it, the more it annoys me!  
Be kind to one another.
