Let me start by saying I have purchased many assembly items from Wayfair over the last few years. I usually laugh at the "hard to assemble " reviews. Literally I have a garage full of tools and can whip out a complex lawn chair in less then twenty on my own. These.... not so much. I did purchase the open box set so it could be my fate but it took a hammer and a crow bar to get the first chair assembled. Two of us. Over an hour later....
Once together they are nice. I hope they hold up as long as the last set I am replacing with these ( last set was fifteen years ). They are low to the ground. They are short but for a patio with a fire pit they are comfy to snuggle down into.  Just be prepared to work for it!
