I just received this yesterday now. So it has been 14hrs since I assembled but see the backseat are already and its very uncomfortable. My back hurts sitting on it. I'm so disappointed I'm even regretting right now. Please, those who are willing to buy this sofa, don't waste your money on this couch. I'm so unhappy  with the purchase. If there was a way to to return it. I would have returned it within 3hrs of assembling
