When the package showed up it looked like it had been unboxed and repacked a couple times. We soon found why: clearly, this sofa had been at least partially assembled before. And it had probably been returned at least once, because we realized the set contained two left armrests instead of left and right ones. Both armrests look the same, but the holes for the bolts are not at the same position. After debating wether to repack the whole thing to return it, or trying to fix it, I decided to drill new holes and put my own bolts to attach the armrest. The built quality if this sofa is dismal, however I can't compare with others, they may all be similar, I don't know. Holes for bolts don't line up properly, bolts are poorly machined, and it's a pain to tighten them with the tiny and cheap Allen key they provide. Metal structure looks sturdy enough but is poorly welded. Typical chinese c r a p .
