(I'm not making this a regular thing, don't worry).
I used to say sitting room, but like settee, at some point I switched over to living room. I'm a Londoner, but had a Midlands mum.
Following on from the other post, I think if you say settee, you probably say sitting room. If you say sofa, you probably say living room or sitting room . Lounge definitely goes with couch.
Which term do you use, what region are you in/from? I'm not counting front room, because that's a separate thing imo. The front room is the good room, or "the parlour" if you're posh.
