Constructing this furniture is more labor intensive than you would think since all the screws don't line up properly. 
Having someone come to your home to assemble is not an option.  But the biggest issue is they ship you 2 right sided sofas so you can't even make the configuration pictured in their online catalog!  Why would that not be clear at time of purchase and delivery!?  To save shipping and production costs?  Ridiculous corporate decision.
