A chic chair, but what material is used to cover it? Actually it's a kind of soft rush called igusa: the material used for the surface of tatami mats. Designer Keita Shimizu's mission is to make the most of igusa's appeal in modern design. To create this beautifully comfortable chair he collaborated with tatami producer Naoki Ishibashi. Their shared goal is to make brand-new interior items that blend into diverse lifestyles, transcending user age, gender and nationality.
