We have a rainy day here so I've been playing....beginning to think maybe less IS more: I moved the other two prints and put them on the walls beside the FP. I am warming up to this now; maybe I was used to having four prints, and now that they are still in the room, it maintains the continuity I was used to. And......back to the chairs; a pair of these PB chairs has been hiding in the recesses of our CL: Pottery Barn Calais chair in leather They are almost brand new so not exactly a fire sale price; they are asking $500 for the pair. I think that's a little high, but assuming the price was right, do you think they would finish things off well? Or should I leave well enough alone? I'd purchase them only if they are more comfortable than what I have, and I won't know that until I see them. I can't test the link until I post, but in case it doesn't show the right one, the CL chairs are brown leather with espresso stain legs. I still really like the sconces but wonder if this is just as nice in some ways. I am now looking at my FP and wondering if the sconces would look good on either side of my mirror! But, no worries, that will have to wait for another day, lol!

A couple of bean bag chairs for teens and all the game stuff in a low TV cabinets where the TV is hung low enough for that height of chair or a small sofa / bed to use for sleepovers along one wall.

That's immensely helpful. Your home has both angled and square corners for traffic flow. A bit of a challenge but not insurmountable. Cool couch set, wish I had room for something similar. I wouldn't worry about the "mess." Fairly typical of folks trying to figure out furniture arrangement. Be sure to take that into account though, the kinds of uses you will have for the space . . . and storage needs. I personally would want some type of bookshelves and/or storage cupboards in that cutout wall space next to the fireplace. I would for certain change the position of the beige armchairs, they look like what we call "time out" chairs for our kids, places you have to sit when you are not allowed to interact with the rest of the group. I can't see anyone willingly choosing to sit in them . . . . YMMV, I am an extrovert . . .

Have you considered modifying and enlarging the pony wall? Pre-wire it for the TV and get rid of the e-center entirely. Put the two loungers on swivel bases. That will give you a lot more flexibility with the furniture arrangement and two focal points. Here's an example, but yours could be larger and higher if need be to get TV at the right height for viewing.
