I have read through the comments posted and I'm very amazed at how productive your followers are. Always looking for compromise, would it be possible to to face the two- seater couch toward the three-seater? I know it puts the two-seater back to the kitchen area but it would pull in the living area to one room. The sunroom behind seems to scream do something with me ( if only to make it a kids playroom). One or two chairs of smaller scale might be added to the open end of the couches. Or a low, wide bookcase that would feel like a faux divider and would add storage. Back to back bookcases would add heft and double the storage.

Rug looks good. Don't get rid of your coffee table. Just slightly sand the top and pick an antique white or light grey paint with primer already in it and give it 2 coats. It will come up great. wouldn't take long to do. Add a tray with candles and small artificial plant, *& would look great. Good luck.

If you like round rug then go round rug. Will suit your gorgeous chair. Just make it large enough for legs of sofa and chair to sit on.

Hi, I would do a bigger lounge rug, one that extends to the base of or under couch but stopes similar to current in other directions. I’m not a fan of dining rugs as diff to keep clean and get fouled by chairs. I think you need to look at the dining room furniture, both the varying styles and placement, it does not appear cohesive. At moment putting a rug under table could help bring the attention to that area. Changing or moving the other furniture and dressing table may help that too.
