Diana 3 seater Sofa
Designer:
Shinsaku Miyamoto
The Diana Sofa by Shinsaku Miyamoto is defined by a gently curved back and arm frame that evokes a sense of Japanese tranquility and restraint. Crafted from solid walnut, the structure is partially wrapped in leather, softening the tactile experience while highlighting the wood’s natural grain and warmth. The leather is finished in a tone close to its natural hue, harmonizing with the depth of the walnut.
