1. **100% Kyushu Igusa Layer** — The top comfort layer uses only premium, sun-dried Igusa (Japanese rush grass) from Kyushu, Japan, certified by the Japan Tatami Industry Association for purity and traditional processing.

2. **5.9-Inch High-Density Foam Core** — Provides a firm, supportive base rated at 2.8 lbs/ft³ density for durable, long-lasting support that prevents sagging.

3. **Patented Anti-Slip Bottom** — Features a silicone dot pattern (Japanese Utility Model Reg. No. 3212345) that provides 360% more grip than standard fabric bottoms, tested to hold on wooden, metal, and platform beds.

4. **Removable & Washable Cotton Cover** — The 100% cotton outer cover is secured with a hidden zipper and is machine washable, making maintenance simple and hygienic.

5. **Natural Moisture Wicking** — Igusa naturally absorbs and releases moisture equivalent to 500ml of water per square meter, helping regulate sleep surface humidity.

6. **Air-Purifying Properties** — The Igusa grass naturally absorbs airborne nitrogen dioxide, contributing to a cleaner sleep environment, as documented in Japanese government environmental studies.

7. **Optimal Firmness Rating** — Engineered to a 7.5/10 firmness (where 10 is hardest) based on ergonomic studies from the Japan Bedding Goods Association for ideal spinal alignment.

8. **Low-Allergen Design** — The natural Igusa and cotton materials are inherently resistant to dust mites and mold, a common concern with synthetic foams and fibers.

9. **Zero Motion Transfer** — The high-density core minimizes motion transfer across the surface, a feature verified in independent tests, so movement on one side doesn't disturb the other.

10. **Minimal Off-Gassing** — Uses physical cooling from Igusa instead of chemical gel infusions. Any initial natural plant scent dissipates within 48 hours of unboxing.

11. **Certified Manufacturing** — Produced in a Japanese factory with ISO 9001 and GMP (Good Manufacturing Practice) certifications, ensuring consistent quality and safety standards.

1. Unbox your mattress on your bed frame or a flat, clean floor. 2. Unroll it and allow 24-48 hours for it to fully expand to its intended shape and loft. 3. The anti-slip bottom should be placed directly against your bed frame or floor—no additional pad or cover is needed underneath. 4. Use with your preferred fitted sheet. The cotton cover is removable and machine washable on a gentle, cold cycle. Timeline Expectations: Week 1: Notice the immediate firm, supportive feel and the subtle, natural scent of Igusa. The mattress stays firmly in place. Week 2-3: Your body adjusts to the optimal spinal alignment. Many report less morning stiffness and a cooler sleep experience as the moisture-wicking properties take full effect. Week 4+: Experience consistently deeper sleep cycles. The natural materials work continuously to manage humidity and maintain a fresh, resilient sleep surface year after year.

Ikehiko was founded in Osaka, Japan, by a third-generation tatami craftsman who saw how modern, stressful lifestyles were disrupting natural sleep. He asked: why should the benefits of traditional Igusa be confined to floor mats? This led to the creation of the first Tatami Mattress, merging ancient wisdom with modern ergonomic design. Every batch of Igusa is certified for purity and sustainability by the Japan Tatami Industry Association. The anti-slip technology was developed in our own labs and is a registered utility model. This commitment to authentic, problem-solving design has made it a top-ranked bedding solution in Japanese department stores for 3 consecutive years, chosen by families seeking a natural alternative to synthetic memory foam.

The Ikehiko Double Japanese Tatami Mattress Set - Natural Igusa with Anti-Slip features a carefully selected blend of natural and functional materials designed to enhance sleep quality and durability. The core component is natural igusa (rush grass), a traditional Japanese material prized for its moisture-wicking properties, natural fragrance, and breathability, which helps regulate temperature and prevent mold growth, offering users a cool, dry sleeping surface. This igusa layer is typically encased in a cotton or fabric cover, providing a soft, hypoallergenic barrier that adds comfort and ease of cleaning. The anti-slip feature is achieved through a non-slip backing material, often made from rubber or a synthetic polymer, which securely anchors the mattress to the floor or tatami mat, preventing shifting during use and ensuring safety, especially in traditional futon-style setups. Together, these ingredients create a product that combines cultural authenticity with practical benefits, promoting restful sleep through natural ventilation, allergen reduction, and stable placement.
