Backless Sectionals, Yes or No?

 We've been running into images of sectionals with backless sections lately and have to ask if they appeal to you? Most of the time a client requests, or we suggest, a sectional sofa it is purely for function - LOTS OF SEATING! (Ok, or a man designing his man cave where bigger is always better. hehe) So, what gives?! Would you choose to add a massive sectional to your home, and then turn around and choose one that doesn't provide maximum space for cozy snuggles and movie-watching goodness?

I do like this room, and don't mind the sectional in here, but I'm not sure what that corner unit is good for other than perhaps keeping a nice and open line of sight into the seating area...

I would hate to be the person stuck sitting without a back on this sectional, unless I was looking to work my core muscles...

So, what are you thoughts? Backless sectionals, in your opinion are they are YES or NO?
