Based on the behavior of cats, who feel stability and comfort by entering a sheltered space, the Korean designers selected the shape of the box. The design searches for balance between the straight line from the square and the curved line of the circle. The result is a modular system that works with special Neodymium magnets coated with PVC, to prevent from sliding. The structures are made in powdercoated steel and birch plywood with a water-based finish that comes in white, jasmine or black.
