IMO he gets a recliner thats it for reclining anything else. You need to decide where you are putting the TV. I would plan it on the stair wall but without pictures hard to know. I think all that will fit is a sectional with the long side along the right wall and a short side dividing that space from the DR a bit. Or a longer style sofa with the recliner on one side and either a matching one on the other or one more chair on that side . An easy way to figure furniture size and placement is to draw the room to scale on graph paper then look at furniture and mark all measurements down then come home and cut out the furniture to scale on cardboard and play with the pieces keeping in mind 36” min walkways . But I do think the TV has to have a home first since in a FR it is the focal point .

Thank you! I was planning on putting the tv on the stair wall so we have the right wall to put furniture on that’s away from the doorway that is next to the stairs. The house isn’t built yet so I only have drawings to go off of, I wish I had pictures! I’m not worried about the reclining loveseat, but the recliner has to stay. We bought it 2 years ago from Lazyboy before we knew we were building so it has a ton of life left and he loves it.

Recliner in the corner by the sliding doors angled toward the tv on the stair wall. Sectional with the long back on the right wall, facing the tv and the short back facing the sliders. Even better, make the sectional with a chaise on the dining room side. He in his recliner and You on your chaise. The kids can have the rest of the sofa!

Here is scale sketch. Each square is one square foot. 84” long x 38” deep sofa max. Recliner on angle on dining end so reclining is easy. No other reclining pieces please. A demilune table with lamp 30” wide will work at window. Max 72” long TV console 18” deep max for TV Wall.

Yes Flo has the recliner and sofa in the position I mention above. I think this is your best bet. I think if you want to maximize seating as you say you could do some small scaled chairs, likely armless slipper style chairs in front of window side by side with a "drink table" between. You must be careful with what goes in front of that window keeping it low because you are low on windows/light in the space. Not knowing your style or color choices just showing you what I mean by a slipper chair and a drink table

A bench in front of windows could work too.

This one is 50” but because sides angle up it works under window.

Thank you Flo for the scale drawing! That was helpful to see how the pieces filled the space. I like the idea of a bench but I don't see anyone actually using it. A comfortable small chair maybe. We are a relaxed bunch and use the living room as a lounge and watch TV type room.
