I see. I wasn't sure where the other door way was. Yes, I think two sofas and two armchairs would work. The problem with sectionals is that they really don't seat as many people as you would think, because adults generally like to have their own "space" and no one wants to sit in the corner or the middle. Ideally you would want the walk way from the the door to the sun room door clear. But because of the off center placement of the fire place and your need to seat larger groups, you may have to bend the rules a bit. How about scooting the window sofa up a bit, to get a more centered arrangement? Sofa tables and consoles are great to stash ottomans underneath for extra casual seating. How would something like this work for you? It will comfortably seat six adults, eight snugly and nine if you count the ottoman as a casual perch. When shopping for sofas, look for a bench seats. They're a little easier to smush people onto because they don't have any cracks.

One idea might be to add a very short wall on the left as you enter the living room so the opening to the living room is the same width as the entry ... and, by doing that you could put wall to wall built ins on that end of the living area, with or without a tv, and still create two separate sitting areas. I don't understand the "bar" against the solid wall behind the pantry and refrigerator. If you changed the pantry to a "butler's pantry" with a pass thru window, that would have made more sense. Is your "bar" a cabinet something built in? Have you considered either closing or narrowing the door between dining and living room and/or creating your pass thru bar there with your piano in the adjoining corner adjacent to the fireplace near the dining room wall? https://www.decorpad.com/search/butler-pantry-pass-through

So this is a sofa with a chaise. Is this your furniture or the previous owner's furniture? You're right to be concerned about blocking the walkway. I don't see that giving the long wall over to the TV is the right call for this space. Are you prepared to think outside the box for this room? What is the dimension of the room?

well, you've succeeded. are you satisfied with the result? I think I would move the TV to the long wall closest to the woodstove -- an electrician can easily move your cable wiring if that's the limiting issue. Then you can put the loveseat facing it on the other long wall, and the two recliners on either side, angled in. Then the space can also serve for conversation a bit, and at least one person can keep warm by the stove. You'll probably find you can then put a long console under the TV, and probably can fit side tables between each recliner and the loveseat.
