love the dining room table and chairs! i like your cofee table choice but you have a lot of black and white and square/rectangle shapes going on so maybe something round in wood like the in style modern table would arm up the space.

What I want to show with this picture are two things, firstly the bar stools and bench as they relate to your table and chairs. The black looking the goods like Jo P suggested. The second is actually a bit of a disagreement with Jo about different timbers. That's something I used to think too but lately I've been seeing different types of timber combined to good effect, like the redder table and chairs here, although I can still understand if this example looks meh to some. Where the timber combos really work is when there are more combined. So if your floor and table legs are different coloured timber and don't really click then introducing a third timber can give you an analogous colour combo with the timbers which works with the contrasting or complementary elements.

I should add, the odd placement of the mustard chair shows where the L shaped couch would go to, if it's off the opposite wall by about a foot.

They are very nice. Where did you see/find these photos originally? Can you contact the person who posted these photos and ask them where they got these tables from? Otherwise I suggest doing a Google search for small round tables and see what appears. You could be lucky and find them online as you search through furniture web sites. Good luck :)
