This is the Retro Moon Bay Bentwood Dining Chair. (Also known as the Crescent-Back Bentwood Chair, it is a derivative of the Sonett / TON style.) It is a modern retro reissue of classic bentwood furniture, continuing the Sonett family’s steam-bending craftsmanship while incorporating a crescent-shaped backrest design that better conforms to the human body. This is not an original TON model, but rather a modern manufacturer’s retro-inspired innovation in bentwood craftsmanship. While retaining the core steam-bending technology, the backrest has been redesigned into a crescent shape that better suits contemporary aesthetics. Compared to the TON 14/18 chairs, its backrest offers a more enveloping feel, with a style leaning toward warm, rustic vintage rather than the elegant, airy vibe of a Viennese café.
