Via thisnext I've found this wonderful furniture at Etsy. The seller says that each piece is treated with a layer of rubber, which make them really special, and also suitable for outdoor use. I'd love to have them in my garden!
At ModernFront you can see many other items (dressoir, sofa, ...), and each of them is available in many different and funny colors. They're expensive, but they really seem to be worth it.
