Demko Organic Coir Mattress Deluxe B Dual Firmness | Medium Firm Vegan Tencel Cover

The Demko Organic Coir Mattress DeLuxe B is crafted for sleepers who want natural support with a balanced, medium‑firm feel — plus the flexibility of two firmness levels in one mattress. Its thoughtful construction blends organic coir fibre with organic latex to create a stable, breathable, and long‑lasting sleep surface.

Balanced Comfort and Dual Firmness. Enjoy medium‑firm support with this organic mattress, crafted to align your body naturally while delivering lasting comfort. Flip it over to experience two distinct firmness levels and discover your ideal sleep surface.

At the core of the DeLuxe B is resilient organic coir, derived from coconut husks. This naturally springy, non‑sinking material keeps the spine level throughout the night, reducing pressure points and preventing the dips or compression common in synthetic foam or spring mattresses. The surrounding layers of organic latex add gentle cushioning without compromising stability, creating a harmonious balance between firmness and comfort.

The coir’s open, airy structure enhances ventilation, helping maintain a cool, fresh sleep environment. This breathability is complemented by your choice of two premium covers. The Vegan Tencel Cover — shown on your product page — uses advanced probiotic technology to create a naturally clean, allergen‑reducing surface. The Organic Wool Cover option offers GOTS‑certified cotton and wool for superior moisture regulation and temperature balance.

Ideal for sleepers who want natural materials, medium‑firm support, and the versatility of dual firmness, the Demko Organic Coir Mattress DeLuxe B offers a pure, adaptable foundation for restorative sleep
