As other reviewers have stated, simple set-up with removal from the box and two pins in the side and they are ready to use!  I am very happy with the quality and feel as if these will hold up well.  I did find these chairs for $25 cheaper AFTER I had ordered them from WayFair, so I was a bit disappointed about that.  I got these on sale from WayFair, but could have gotten them even cheaper if I had looked more.
