if i'm going to pay for a couch in any context, i'm going to be particular enough to make sure i can lie flat on it, which means i need 70" worth of cushions, given that i'm a hair under 70" tall. but i also need the structure to be well under 80", preferably closer to 75". i'm looking for very thin arm rests, which is difficult to find for cheap.

so, i think i want a more expensive couch and i'm better off buying it second hand for cheap and then paying for somebody to move it than i am buying a less expensive couch new.
