Ritzwell, a Japanese manufacturer of upholstered furniture, has been associated with superior quality materials, the highest level of craftsmanship and research since 1992. The company’s production facility is based in Fukuoka (on the northern coast of Kyushu); it has three showrooms in Tokyo, Osaka and Fukuoka, and a worldwide distribution network. Its Italian hub is in Milan.

Ritzwell designs are based on organic modernism that combines a balanced, simple form with all the beauty and grace of the materials. Each piece goes through a feedback cycle of evaluation and redesign, examining both utility and aesthetics, and emerges stripped of extraneous elements to leave only the fascination of Ritzwell furniture that grows more beautiful with time. The more you use it, the more the shape of the backrest, the smoothness of the leather, even the wrinkles, remember your body and mold to it, changing over the years to grow ever closer.
