This is definitely a large sofa however it can be set up as a corner piece or a straight sofa. It is super comfortable and the cushions are very thick and plush. The back cushions are not attached which is not a big deal as they are full and puffy and more or less stay in place. I find the back to be low but for what I want it for it is just fine. Also when I sit up straight the back hits me in just the right spot to feel good and supported. It has very deep seats and I actually sit up higher than I did on my old standard sized couch. For me modular sofas are the way to go. I must say that this sofa is of great quality. The throw pillows are very comfy as well. I would buy this again and would also recommend it to anyone else in need of a longer sofa. All of my friends and family were very impressed by it. Great price too!!!
