This rainbow stack may look familiar, but it's fun for adults, too. Inspired by the iconic children's toy, Vancouver-based Cumulus Project created Mound of Rounds, a colorful stack of cushions on a wheeled platform. Unstack for extra seating or a pillow to rest your head, and the platform doubles as a low table.
