I believe in your earlier post I had recommended for you to put the sofas adjacent like the last photo you have here. That is the best configuration so the vents in the back wall can easily have space and the chairs can be moved and people walk in easier.

I'd try one large ottoman coffee table for ll the seating.

Yes, a much larger area rug with some interest.

What will you hang over the swivel chairs, it needs something large to balance the dark wall of the TV.

walls tbd 🤪

Why do you need a rug on top of the carpet? A much bigger coffee table/ottoman will better fill the space. That carpet
seems a trip hazard.

I have a rug on top of carpet for added color/graphics in my room. What is the big black hole to the left of the fireplace? That needs attention.

Yes that is a suncken area painted black where the tv goes.

It's amazing how certain visuals from a computer or phone screen can look warped. Definitely did not see that niche where the TV is. Paint that a warm wood tone or white. It WILL absolutely bring more unity to the rest of the room and as well, add depth to this living area.

What about a large round rug that would accommodate the angle in the wall…

10 foot diameter on Wayfair. I don’t know what size you would really need here. It might not be possible to find.
