I think a sectional might fill the space more. That's kind of what I have going on right now in my living room. (Pictured below...don't mind my dog) Although, I did separate my sectional and put one in front of the windows and the other right across and the 2 chairs facing the fireplace and liked the set up. (2 pictures below) Hopefully that helps out a little and gives you some ideas.

I like what you have. The furniture has room to breathe. The only question is why is there no seating opposite the pair of chairs? I envision a wood rocking chair that doesn't take up visual weight but balances the other furniture.

I think I'd get a larger (8 or 9 ft) sofa that faces the tv, then put your existing sofa facing the blue chairs. That gives you plenty of seating, and the proportions will feel better. So, essentially, you'll be creating a U-shaped conversation area, with the largest seating facing the FP/TV.

Love what you have and definitely a keeper. I do think that you need another piece and that’s why I agree with Sabrina. Smart idea but honestly you can also add a chaise, a bench....

Thanks everyone for the comments so far. Two things to mention:

1. If we keep the couch I am planning to add another side chair to the left of the couch (view from second photo).

2. Directly behind me in the second photo is the entryway and front door. I'm hesitant to do anything too bulky on that side as a result.

Yes, another chair to the left of the couch as you mentioned would be fine.

We are very much "feet up" people. Instead of using a large ottoman, we have smaller hassocks on legs. Lower and smaller than an ottoman, and light enough to easily move around between chairs as needed. Also very popular with my young granddaughters as low chairs. The slightly wider low hassock often gets used at the same time by DH and me. Pouffs would work too.

i would add a piece like this opposite the blue chairs

I feel like the scale of the blue chairs look so big in comparison to the sofa.

I was going to also say that I would use your current couch across from those wonderful blue chairs... in that room, that couch kind of looks like a love seat scale and I think it would look fabulous across from those chairs. Then get a larger scale sofa for your main, tv viewing sofa and you are left with abundant seating that looks appropriate for the scale of the beautiful room.

You have amazing taste. You Totally have a flair for this stuff. I would leave it up to you. Really!! Your good!
