Sofas are what I have in my sitting room, couches are what other people have in their living rooms and lounges (these people also tend to have other hateful things like television cabinets disguised as Victorian bureaus) or what one lays on at the doctor's or psychiatrist's office in order to be examined.
settee which is what it is. but out of them two i say sofa
Both function the same way but i would prefer to sit on a Sofa..........
