Handcrafted in San Francisco from layers of pure organic cotton layers encased in an organic cotton fabric shell, the Organic Cotton Shiki Futon Mattress delivers the most traditional Japanese floor-sleeping experience available—free from wool, foam, synthetic fibers. Dense, breathable, and genuinely grounded, this is a mattress built around what's in it as much as what isn't. The Organic Cotton Shiki Futon excels at keeping the spine in a neutral, well-supported position throughout the night. For stomach sleepers, the firm, stable surface prevents the hips from dipping and the lower back from arching—one of the most common causes of morning discomfort. Back sleepers benefit from the even, unyielding support that keeps the shoulders open and the lumbar region properly aligned. Cotton absorbs moisture and holds onto it, therefore compresses more easily then our shiki futons with wool.

If you are a side sleeper or weigh more than 145 lbs, a more structured sleep surface will serve you better. We recommend exploring the Latex and Wool Shikibuton or the Latex and PLA Shikibuton for additional pressure relief and long-term structural support.

Choose from a 3-inch profile for a firm, minimalist feel that's true to the original Shikibuton tradition, or a 5-inch option for a touch more cushion while still maintaining that clean, supportive foundation. Both are available in standard futon sizes with your choice of organic or natural cotton cover.
