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! :-)

I'm sorry, but the strong colors of the stripe fight with the rug. I think the eye will keep going back and forth between the two. So far I haven't liked any of the fabrics shown; none seems like just the right solution. I would keep looking. Call me crazy but I suddenly had a vision of an ice blue background with stylized cream flowers for the chairs. The flowers would be fairly large, with vining stems running between them. This pictures shows the opposite, cream background and blue flowers, that also would work. <div><a href='[https://www.houzz.com/photos/kitchen-remodel-southwestern-dining-room-phoenix-phvw-vp~3846944[(https://www.houzz.com/photos/kitchen-remodel-southwestern-dining-room-phoenix-phvw-vp~3846944)' target='_blank'><img src='https://st.hzcdn.com/simgs/de813a23018a6b69_8-9605/southwestern-dining-room.jpg' alt='' border=0 width='500' height='324' nopin='nopin' ondragstart='return false;' onselectstart='return false;' oncontextmenu='return false;'/></a></div><div style='color:#444;'><small><a style="text-decoration:none;color:#444;" href="https://www.houzz.com/user/mtsolem"; target="_blank">Photo by Marianne Solem</a> - <a style="text-decoration:none;color:#444;" href="[https://www.houzz.com/photos/dining-room-ideas-phbr0-bp~t_722"[(https://www.houzz.com/photos/dining-room-ideas-phbr0-bp~t_722-room-ideas-phbr0-bp~t_722); target="_blank">Search dining room design ideas</a></small></div> <div><a href='[https://www.houzz.com/photos/kitchen-remodel-southwestern-dining-room-phoenix-phvw-vp~3846944[(https://www.houzz.com/photos/kitchen-remodel-southwestern-dining-room-phoenix-phvw-vp~3846944)' target='_blank'><img src='https://st.hzcdn.com/simgs/de813a23018a6b69_8-9605/southwestern-dining-room.jpg' alt='' border=0 width='500' height='324' nopin='nopin' ondragstart='return false;' onselectstart='return false;' oncontextmenu='return false;'/></a></div><div style='color:#444;'><small><a style="text-decoration:none;color:#444;" href="https://www.houzz.com/user/mtsolem"; target="_blank">Photo by Marianne Solem</a> - <a style="text-decoration:none;color:#444;" href="[https://www.houzz.com/photos/dining-room-ideas-phbr0-bp~t_722"[(https://www.houzz.com/photos/dining-room-ideas-phbr0-bp~t_722-room-ideas-phbr0-bp~t_722); target="_blank">Search dining room design ideas</a></small></div> <div><a href='https://www.houzz.com/photos/kitchen-remodel-southwestern-dining-room-phoenix-phvw-vp~3846944' target='_blank'><img src='https://st.hzcdn.com/simgs/de813a23018a6b69_8-9605/southwestern-dining-room.jpg' alt='' border=0 width='500' height='324' nopin='nopin' ondragstart='return false;' onselectstart='return false;' oncontextmenu='return false;'/></a></div><div style='color:#444;'><small><a style="text-decoration:none;color:#444;" href="https://www.houzz.com/user/mtsolem" target="_blank">Photo by Marianne Solem</a> - <a style="text-decoration:none;color:#444;" href="https://www.houzz.com/photos/dining-room-ideas-phbr0-bp~t_722" target="_blank">Search dining room design ideas</a></small></div>

This is so much easier when you provide us with all the naturally coordinating fabrics so that we know we're in your price range. https://www.fabric.com/find?brands-and-designers=magnolia-home-fashions&colorfamily=blue-and-white I would have started with a rug first, but now that you have your draperies being fabricated, I would select #4 for the seats on your chairs. I wouldn't place an area rug on top of that thick carpet. I would recommend the carpet be replaced with hardsurface flooring and then an area rug selected. Since your fabric design is a batik style, I would two tone your wall paint. Here are some computer generated paint colors that coordinate with the fabric.

I'd use a finished, top grain leather myself, probably in the green/sage family, everything wipes off it and it's classic for a Chippendale chair. You can do those slip seats yourself, they're not hard though you will want to have an electric staple gun. If you go fabric, Crypton or Sunbrella Performance fabrics are soap and water cleanable.
