Assembly was difficult and I believe because what was sent was improperly prepared before. The two holes you see on the arms were supposed to be on the back of the couch for the provided two prong head board like cushions. I had to create my own holes aka cut into my couch. Now each arm has two random holes as a result. Additionally, the covers don’t fit properly. I love this couch but the negligence with preparing before sending made putting it together incredibly frustrating.
