The designer versions of this chair will cost you a pretty penny (well for frugal folks like me) at ~$650 a chair. I've spied these at Home Goods on a good day and ebay offers a plethora of them every so often but
Updated with Suzie's response (for anyone considering the Macau chair from Ballard): "Awww, thanks for featuring my dining room! OOhh, I actually purchased the chairs for a little less than $200 each with coupon codes. You know I loves me some codes! The chairs are surprisingly comfy! They are a lot tougher and stronger than I expected them to be as well. The cushions are more off-white than stark white as shown in the photo above, but the whole process was a biatch. They kept sending me chairs with paint chipped off and scratches, so I had to call and get the damaged chairs picked up by UPS (no charge) and then new chairs sent. I think I sent back a total of 4 chairs! But, for all the trouble, they actually sent me a $150 gift certificate so it all balanced out! Let me know if you have any other questions. I can take a close up photo if you'd like!"
Thanks for the helpful input, S!!
