Have you tried Anthropologie?

Anthropologie has this kinds of bohemian furniture - not as nice but relativey inexpensive.

The other option is to have a chair done by a local upholstery shop. I had a vintage chair from the 1920's with carved wood frame redone in a very contemporary fabric.

Anything with color will be custom. I walked through a large mid/high end furniture showroom a few weeks ago and everything was white, grey or beige.

I would look for nice used chairs on your local Craigslist, Next door, FB market place, or similar, and have them reupholstered in whatever fabric you like.

I will check out Anthropologie.

I might have to go the reupholstery route.  

I found this actual fabric on Etsy, but it's pretty steep. The only color I have in my living/dining combo is the the rug under the table.  I think it could handle two bold chairs.

Nothing about the photo says this space could handle a mulit-color Zebra stripe. Do you have any art in those colors? That might make a difference. Go with a b/w Zebra print or remove the rug. The solid blue in the chair pairs nicely.

My pictures won't do the space justice or show true scale.  Ceiling starts at 9ft and rises to 20 ft.  I don't have anything in the room except the dining table, buffet, and rug.  So the space is very empty.

Is the table not centered under the light fixture? And it's hung way too high. It should be about four feet above the table. The table needs to rotated 90 degrees in that long space. Place a couple of armchairs and maybe a game table or something under the arch window. Make use of that space.

Get a much larger rug that complements the Dining room rug and center it in the Living room. Place your conversational seating on it, a sofa and two club chairs and a coffee table.

Instead of those new chairs, get some slipcovers for your two captain's chairs. That soft blue velvet in the chair you like would be perfect here. Use the same or similar color elsewhere in the room. If you want drapes, they would be perfect in the same blue.

And plants, a nice tall plant in the corner by the small window would bring some additional life and softness. Smaller ones on each side of the front door in raised pot or urns.
