The assembly of the couch was very simple and easy to do on your own. 

The legs were installed into the armrests not the actual couch.  (Usually they are screwed to the bottom of the couch.) However it seems like the weight will hold evenly.  

The back and the armrests (sides) easily slide into the metal racks already installed. Very easy assembly. As Gad comfort goes, this couch is one of those that will put you to sleep, it is very plush.
