given that you have small children and may need to change the chairs in the foreseeable future, i would recommend the ingolf chairs from ikea (http://www.ikea.com/us/en/catalog/products/30125923/#/30125923). they are solid wood and affordable. i wouldn't combine styles or finishes since you already have two finishes in the dining room, so one more is more than enough. then, i would concentrate on adding some color to the room with some vintage pottery or glass.

Your dining table and credenza are great, but I'd mix the materials. I think there's just too much woodiness. The Madeleine metal chairs are a great idea.

Here is what the OP is talking about: http://www.restorationhardware.com/catalog/product/product.jsp?productId=prod1860430&categoryId=cat1830094

I have a similar table and dining room set up. I also have 4 small kids who over the years have destroyed a few sets of cheap chairs. My latest solution, which has held up nicely for the last few years, is a collection of queen anne style vintage chairs. They are all slightly different, picked up at garage sales, the flea market, thrift stores and even on the side of the road! Each for around $15 or less. I have covered the seat of each chair in the same Marimekko coated fabric that is easily wiped. I am so happy with them. If one breaks it is easy to replace, I just keep a spare roll of fabric for extra chairs.

I like the idea of tying in the cane, but I'd try to also get some fabric going on, so I'd find two upholstered chairs.

I think those white molded "s" chairs would work great here and would be easy to clean. Another thought is getting a mixed set of vintage Goodform or other office chairs in various colors, even mixing in some with wheels. Nothing holds up better than those old chairs and you can find them cheap.

I think a bench on one side, arm chairs on the end and armless chairs in that same style on the other side would be cute

My parents had teak Windsor chairs that came with their dining room table from the time I was an infant until well into when I was in college. They were then inherited by my cousin, who subsequently passed them along to me. With a little bit of Murphy's Oil and/or some hydrating wood cleaner once a quarter or every other month, they've lasted almost thirty years through kids, dogs, moves...everything. If you invest in some quality wood that you love, you won't be replacing it every couple of years and I think you'll thank yourself (and save money) in the long run.

I am a firm believer that big wood tables look best with molded plastic or fiberglass chairs.

You can find some affordable options on amazon that you won't feel guilty about your kids being rough on.

Would you consider an upholstered parson's chair? You could get slip covers for every day use, and have a nicer fabric underneath for special occasions. You could also get some arm chairs for the heads. I like the Leighton, Colette, and Miles chairs from Crate and Barrel. Something in a yellow-ish tan or cream would tie in with the credenza I think.

In all honesty, those Madeleine chairs look very uncomfortable!

I do like the Vintage French Cane Back Chairs, but having something you could throw in the wash would be good (which you can't do with that seat), and I am not sure if I care for the wood finish. On my monitor, the burnt oak finish reads very cool and greenish, which I'm not sure if it would really compliment the credenza.

Just my .02

I wouldn't mix in another wood finish. I'd choose either metal or fabric for the adults and trip traps for the kids in fun colors.

Get a mix of different Windsor style chairs.

I think metals would be great in this situation. They're as heavy duty as you can get. Your dining room has such a richness to it that I think plastics would be too much of a style contrast. A chrome and leather combo might be nice if you're not willing to go all aluminum.

If metals are too industrial and/or masculine for you, maybe the scoop side chair at C&B would be nice. I love whites and woods together.

We also have only one dining place at our house, and I found some awesome chrome cantilever chairs with woven leather seats for a steal on craigslist. They're comfortable, durable, beautiful and were inexpensive enough I'm not going to freak if my kids dirty them up. On either end of the table, I have taller dining chairs with washable slipcovers.

Being a (mature) student in an unfurnished rental with little cash to spare, I've gone for a budget option that looks really good. I bought 2 cheap, solid wood chairs from Ikea at about £12 each, and picked up the rest in charity (thrift) shops, free on Gumtree (Craigslist) and one off the street. Cleaned then up and painted them. I bought a tin of bright blue washable paint to paint my bed, but there was so much left over I managed to paint all the chairs the same shade. They look great around my plain old pine dining table and cost very little to make.

I have been through cheap plastic Ikea chairs and vintage, painted rattan chairs with fabric covered seats in Mod Green Pod fabric. It's impossible to keep fabric seat covers clean. I've finally settled on Eames-inspired molded plastic side chairs and two armchairs and have been pleased with the look with my dark-stained rustic, x-base table and with the ease of cleaning.

first thought was u.s. navy surplus chairs in silver metal, something with a classic line. dwr has the 111 red ones on sale this week & those also would look nice in the space.

check these out...soho dining chairs from i.o. metro (upholstered in grey or taupe with wooden legs)...slipcovered parsons chair from ballard designs...vapor chair from cb2 (clear plastic with chrome legs)...joe chair from cb2 (upholstered in grey tweed with polished nickel legs)...erland chair from ikea (white plastic with chrome legs)...i have been looking for chairs for some time myself. I am 5'4'' and most chair seats are too high for me, but this may not be a problem for you. all the chairs i listed are great looking and also comfortable for both me an my husband.
