The TLSB chair is a scrollback chair whose name is an acronym for Triangular-Legged Scroll-Back, highlighting its unique design in which the back pillars, crosspiece, and rear legs are arranged in a triangle, and a rattan-covered seat frame is fixed on top of it. This innovative structure, which was conceived to ensure efficient material use and rigidity, has made the chair even lighter, evolving it into an easy- touse furniture item that can be lifted with one hand. While boldly modifying the structure itself, we have retained and refined the original elements such as the central stay and scrolls, resulting in a design that feels like a fusion of classic and modern, Western and Eastern. The small seat, slightly high curved backrest, and unique appearance, which imparts a sense of volume, still feel fresh even after 150 years.
