Could you have the new couch and loveseat facing each other? That's popular way to place seating. Without seeing more of the living room, and what else you have in there, it's hard to say. A nice rug between the two in that arrangement would be a great way to soften the room. Do you have the new pieces picked out?

Please post two more photos - take one with your back to the windows and take one with your back to the bar stools.

People really don't like sitting in a loveseat with someone else. It's too confining and "close". You're much better with 2 swivel chairs flanking the sofa so everyone is comfortable and also can watch tv if they wish.

That was my thought also, have a chair flanking the couch on either end instead of the love seat. The room will look less crowded and you'll actually have more seating. However, the TV would have to go over the fireplace, which unfortunately seems like the logical place to put it, unless there is enough space on either side of the fireplace, which there doesn't seem to be. Looking at your overall space, a glass and metal coffee table would make the room look more spacious, and would also show more of the carpet. I hope your new furniture will have more graceful lines and a smaller silhouette to better fit this space.

If the TV has to go above the fireplace, you might want to look at the down-and-out-mount or other similar wall mounts that are height adjustable.

Or sofa opposite fireplace, 2 chairs on window side, tv where it is over console?

I would keep the TV where it is, but lower. Put a longer sofa under the window with one swivel chair next to it and the fireplace and the other around the base of the stairs. Thin of an ottoman instead of a coffee table so one could out their feet up and still function like a coffee table.

You could a to scale drawing (1 inch equals 1 foot) with the measurements of the walls openings, door, window and fireplace. Then cut out rectangles the size of furniture you want in the space. Post the drawing for more feedback.

I would put tv in corner between window and fireplace at slight angle. It’s up too high and floating in nowhere.

Put the sofa in front of the window facing the TV, pulled a little closer to the fireplace than the loveseat in your original post. Put the two chairs facing the sofa and equal distance from the fireplace. Get a coffee table big enough for all seats to use it.
