12-inch King Mattress Five Layer Foam Zoned Support Japanese Crafted Wave Knit Cover

Japanese manufacturing philosophy runs through every layer of this king mattress, from the precisely selected foam stack to the black-and-white wave knit cover drawn from traditional ink pattern aesthetics. Five engineered foam layers work together to deliver zoned ergonomic support across shoulders, hips, and lower back while the high-density base resists sagging over years of use. The result is a mattress that handles both comfort and longevity without compromise — a pairing that defines the best of Japanese industrial craft.
