I am not sure one why review said it took her “engineer” husband to put one together in 45 minutes. I probably put both of these together in 30 minutes and I’m just a teachermom. Yes I agree with another reviewer about how they label the parts different, one sticker was on the front when others where on the back. I had no issues on my holes lining up correctly so I guess I got lucky. But honestly, these chairs are comfy and put the perfect touch on my porch. Couldn’t be happier.
