The finest shiki futon The Futon Shop makes, our Japanese Style Wool and Natural Latex Shiki Futon is where centuries-old sleeping wisdom meets American craftsmanship — Free of foam, synthetic fibers, and chemical flame retardants. At its heart is a Dunlop latex core that works with your body, gently supporting your hips, shoulders, and thighs in any sleep position while keeping your spine in healthy alignment — Surrounding the latex core is a layer of natural virgin wool that breathes, naturally regulates your body temperature through every season, and gently relaxes tense muscles to ease you into a deeper, more peaceful sleep. Every ingredient was chosen with your well-being in mind — no synthetic fibers, no chemical flame retardants, just honest natural materials that have stood the test of time and that even the most chemically sensitive sleepers can trust. Handcrafted stitch by stitch by skilled artisans in the USA, this mattress reflects The Futon Shop's deep commitment to quality, longevity, and a genuinely healthier home.
