I LOVE these chairs! They were easy to put together, took just a few minutes each (i think in total for all 4 it was maybe 40 minutes?). I will say, that using the allen wrench provided make it difficult to make sure you get the bolts perfectly tight (had to grab the set out of the tool-box to make sure the chairs weren't wobbly). One of the chairs had arrived cracked, but thanks to Wayfair's amazing customer service, I was made whole in no time. 
Ultimately, once I had put them all together, they look gorgeous. So classy and elegant, but even better, they are EXTREMELY comfortable to sit in. I am extremely excited about these Chairs. I was able to work at my dining room table for a few hours without feeling uncomfortable, and we even had company over and got many compliments. I would definitely not hesitate to recommend these chairs at all!
