UPDATE: We realized that the loveseat arms wouldn’t go on because they had the exact same brackets as the couch, not locking mates. We stripped and rebuilt the front panel and supports, and confirmed that the loveseat was knowingly made with several bad 
/twisted pieces of wood. There’s no way a quality check was ever done in the factory. 

I really wanted to love this living room set. We spent 5 hours trying to get the arms to fit onto the brackets and eventually gave up on the loveseat. Several parts of it looked like it was made with bad pieces of wood - the front panel of the loveseat was very warped and one of the interior supports was made with a split piece of wood. The sofa cushions had bunched fabric. All of the cushions were hard. I would not recommend this for a tv room sofa.
