The rug needs to have at least the front feet of the sectional on it. Looks fine to me the way it is.

Does it need to be a table? Could a live-edge shelf be used instead? It would echo the natural tree form of the coat rack and that silver finish would look just beautiful with glowing wood.

Shirley, I probably found the lamp on Wayfair by filtering for buffet lamps. That said, I don't know what exact size you need, but you can figure it by measuring from the top of your console to a point about 3/4 the height of the mirror and look at buffet lamps that are close to that measurement. Then put something shorter and squatter on the other side to balance the lamp.

I'd suggest you get a slim console for the TV 12"- 15" at most and definitely get a smaller coffee table or skip it altogether and add a side table. I've created a mock up of your space to help you visualize this better. I also think you could move the bookcase to the corner by the window and move one of your accent chairs to create a window seat. Might make a nice reading corner.
