Firstly, I absolutely love this set! Shipment went great and looks just as I expected from the pictures. It brightened up our kitchen and the storage space under the seats is extremely convenient. This would fit about 6 or 7 adults. Assembly took us a bit under 4 hours total with a team of 3 people (father and 2 daughters) none having much experience with building too many things.
I want to share my measurements
