When two become one: the simple day bed made of birch plywood can grow, depending on how it is stacked. The Swiss design label blueroom offers a single bed called Bed no1, which, if combined with another single bed and a ladder, a guardrail, and four foot bracings, can be turned into a loft bed. You can not only change the bed’s appearance, but also combine different colors, such as natural wood, white, rose, rouge, lime or bleu, to create a unique color experience. Kids can turn the bed into a castle or a ship in their imagination, and when they are teenagers they can turn the two single beds into a spacious couch. Bed no1’s stable workmanship and clever design makes it especially durable and sustainable.
