I would pick a darker or medium brown from your floor. I love darker brown myself.

Lovely floors and space!

Dark/medium dark brown (not reddish brown)

Interesting you chose a tressel table torreykm, I was thinking the way the fixture is hung I wondered if there was a banquet on that wall.

I think a combo of paint to coordinate with the cabinets and wainscoting, and a wood stained top would be great. It's a more casual space so I think a very formal dining suite would be out of place.

Darker brown. I have just finished doing a facelift to my bathroom and when I changed the wall color to a color similar to yours, and painted the mirror white, I stopped before going further. My vanity has a white top and a dark brown bottom. Further, the baskets in the white shelves have dark brown webbing. It all looks really good together. I love the dark brown, white, and grey/green/blue combo.

I also liked these walnut ones from room and board:

I love those walnut pieces for your room. A little unexpected and not as cottagey looking as the painted pieces (although your room is so pretty, you probably can't go wrong).
