Chairs are very nice and I really like your table!

I wouldn't put a chair there, that would seem a little awkwardly out of place. But I agree the wall does need something. I'd probably go with matching cabinets on either side of the fireplace. Or maybe a tall plant for a little bit of greenery.  I do think  the room is crying out for a rug. A rug would  take less emphasis off of that bare wall because your eye would go to the rug and break up the bare floor to the bare wall.  I'm not bothered by  the TV above the fireplace. The room is to live in not for a magazine picture. People do watch TV

Similar: 1940's. bent arm chair. Nice find, even if you can't find another, have yous professionally refurbished. You always find something from the era to relate to it. Or, buy these for $3200.00:

I would do a similar style chair in the blue/gray from the rug
