These are the Milli Chairs designed by Duffy London. They were inspired by millipedes. They cost $2,350 apiece or $3,900/pair. For reference, $2,350 is more money than I will pay for all the furniture I will ever buy in my entire life. You know what this couch cost? The price of a cell phone call to ask a friend if I could borrow his truck after I spotted it by the side of the road.
Keep going for several shots of the possibilities when you buy two.
