Wonderful seating set! Easy to assemble, but time consuming. All the bolts are the same so that’s easy. No deciding which one to use. Unfortunately they are fine thread and Allen head. It took me an hour and a half to assemble it all, but almost all that time is sitting down turning the Allen wrench over and over again. If you have a power screwdriver and an Allen bit, use it. I only had a drill and it was too big to get close to the sides and use in the bolts. Even though it says two people recommended, I did it by myself just fine. Sure, another person to hold a piece in place would be easier, but it really wasn’t a problem alone. 
It’s really a great, sturdy set at a great price!! We love it!!
