I don't understand all the whinny cry babies that complained about how hard it was to assemble these chairs. I had them both together in less than an hour.  If I didn't keep dropping the bolts it  would have taken less time.  The only problem I had was the print on the instructions was way too small for me so I had to wear 2 pair of glasses.  That cost you a star. The chairs are great, comfortable and seem plenty sturdy enough for my 225lbs.
