Received two boxes on the same day, the bigger of the two was a bit worse for wear. Unboxing revealed that the main part of the sofa was a little bent, but we were able to fix it. 
I can’t stress enough how important it is to put it together loosely and then finish tightening after the fact. 
In total it took about 1.5 to 2 hours to our together and it was relatively easy once you figured out the basic assembly instructions. 
I’ll update later when I’ve been able to us the set more frequently. It’s headed to storage for the winter.
