I've been low-grade fixated on the idea of vintage Ikea kids furniture ever since I found the "Kid Size" exhibition organized by the Vitra Design Museum. I've been keeping an eye out for any pieces to turn up for sale. Thanks to Ikea's built-in disposability and lack of preciousness, not much seems to have survived. Oh, and also, I'm drunk and looking for my keys under the streetlight; Ikea didn't build a store outside Scandinavia before the 1970s, so the only way you'd probably ever even get a chance of finding vintage stuff is to go thrifting in Sweden itself.
Or to find someone who did. The incredible, simple, red-painted, bent beech table and chairs set above was designed for Ikea by Karin Mobring in 1963. It's featured in Vitra's Kid Size collection and exhibition, and Etienne, the incredible Dutch dealer behind Mid Mod Design, has one available right now. With extra chairs. And if you're not shipping them to the US, they don't even seem that expensive.
