Don't write off fabric just yet. You could use microsuede, Crypton, or any of the newer indoor/outdoor fabrics available now. My DD chucked a whole bowl of tomato soup on one of my pale blue microsuede chairs and I swear it cleaned up perfectly. I think softer lines, and fabric, would bring some balance to the angularity of your room. I love the artwork and might think about pulling some color from the painting next to the stairs into said fabric. I know and love your kitchen from the KB. Nice to see you over here. looking forward to seeing more! :-)

Your place looks really rustic, reminds me of our old ski house. What do the legs on your table look like? I don't like your first chair option for your place. Depending on the table legs I think the last two chairs might be a good option. I like the turquoise stool in either that or a cream color. I like the idea of the dark stained legs because of the nice contrast they give to the pine in the house.

We have had these dining room chairs for about 20 years and they are starting to fall apart. Can anyone please help me choose some new ones? Looking for something casual and comfortable. As you can see we have a lot of black, stained wood, and white in the space.

It looks like you have enough room to pull the sectional toward the fireplace quite a bit. Even though that doesn't give you more floor space in the dining room, it would give the table and chairs more breathing room without being so close to the back of the sofa. A sleeker table and chairs, as posted by Patricia, would also make the space seem more spacious. Instead of a matching console or china cabinet, I'd think about either a color or something to match the wall color (or just light, like the walls). If you do a large piece like you have now, I'd do light. A long, low console could be any color, but with the wood floors and similarly colored tile, a contrasting color might be nice. If you did a lower console or buffet where the china cabinet is now with a large piece of art over it, in the view from the area of the green chairs that doorway to the kitchen would frame the view to the art instead of the wood cabinet you see now. It's a pretty home!
