You’ll never look at an old cardboard box the same way again once you’ve seen what the creative geniuses at Ideacarton can do with it. Their latest cool design is the Navrik-Classic chair, which is handmade from corrugated cardboard. Far stronger and sturdier that it looks, it is a fine example of the Scandinavian philosophy of minimal fuss and maximum comfort. Use is as a statement piece on its own, or buy several as an alternative to traditional dining chairs. Around £97.
