The Stone Garden sofa is a backrest sofa that embodies the philosophy of the Stone Garden collection. The proportions of the newly introduced backrest have been carefully designed so as not to disturb the horizontal orientation that defines traditional Japanese space. Set at a height averaging more than 100 mm lower than those of our standard sofas, the backrest stands out as one of the product’s most distinctive features. To ensure structural integrity, the sofa has been reimagined with a wooden-frame core. Upon this foundation, layers of urethane and feather are balanced to recreate the soft, enveloping comfort and subtle resilience that are intrinsic to Stone Garden. This piece reveals its full character when paired with futon mattresses or tatami. By introducing the spatial principles inherent in tatami modules as a new layer in contemporary architectural space, it creates living areas that feel at once grounded, open, and expansive.
