My friend Emily spotted this fantastic radiator-chair, a one-of-a-kind sculpture from Von Thiel and Co. at a shop in Toronto. At CDN$1,490, it's a little pricier than you might want to spend on a chair that probably won't be all that comfortable for protracted use (Emily assures me it was great for a short sit-down, though!), but it's a better world that has this radiator-cum-chair in it.
(Thanks, Emily!)
