Thank you for your interest in our project. I contacted the owners regarding where they purchased the chairs. They purchased them in 2011 - along with the sofa - at Design Within Reach. They are the "Raleigh" armchairs and sofa with a "Beige Wool" fabric. They looked at the DWR website and saw that the fabric names may have changed. The one that is closest to the "Beige Wool" now looks to be "Tumbleweed" - so you should check on that.
You guys did a great job, Allen Construction! It's beautiful! I wish we had somebody like you for our mid-century modern whole-house renovation. *sigh*
