Recently received the order. The delivery men were kind enough to bring to the 6th floor where our apartment is — couldn't imagine having to do that myself. The couches were pretty easy to assemble, as it essentially comes already put together. All you have to do is screw in the back support and the four legs. Took maybe an hour total. 

I'm writing this the day we put it together, so I don't really have an opinion yet on the quality of the couches themselves. But so far so good. I have high hopes!
