Diana Armchair
Designer:
Shinsaku Miyamoto
Diana Armchair by Ritzwell, designed by Shinsaku Miyamoto, reflects a calm and considered approach to seating inspired by Japanese sensibilities. Its gently curved back and arm frame create a sense of enclosure, while the solid walnut structure is partially wrapped in leather to soften the visual weight of the wood. The leather is kept close to its natural tone, allowing the richness of the walnut grain to remain central to the piece’s quiet, balanced character.
