We're pretty much starting over from scratch in this room, so we have an opportunity to change the layout from its current configuration, which looks like this
We could add another chair, like in the drawing below, but then the best seats in the room would be the side chairs. I'd rather get comfy on the couch.
We briefly considered a love seat instead of two chairs, but this actually limited our seating even further because really, only one person can comfortably sit on a love seat. It also still leaves one of us eating our dinner lying down.
That brought us to putting the sofa directly across from the TV.
As you can see, that's not going to work either. The sofa would block all the traffic flow in and out of the room, and the two chairs would probably look weird blocking the TV like that.
Finally, we arrived at the "TV over the Fireplace" solution.
We were reluctant to put a TV over our only fireplace in the house, but as you can see, it really does give us plenty of seating and allows for the best flow of traffic.
Have you done it in your own home?
