Demko Organic Coir Mattress Deluxe C | Medium Firm Vegan Tencel Cover

The Demko Organic Coir Mattress DeLuxe C is crafted for sleepers who want a naturally supportive, breathable mattress with a balanced medium–firm feel. Built around a resilient organic coir fibre core and cushioned with organic latex, it delivers stable spinal alignment while maintaining gentle surface comfort.

This organic mattress offers a feel between medium and firm. On a solid plank base, it provides firm support; on a flexible slatted base, it feels closer to medium‑firm. For a true medium feel, we recommend our DeLuxe B mattress.

The organic coir core — derived from coconut husks — provides natural spring, durability, and long‑lasting structural integrity. Its non‑sinking, evenly supportive design keeps the body level throughout the night, reducing pressure on the spine and preventing the dips or compression common in synthetic foam or spring mattresses. The surrounding layers of organic latex add comfort and pressure relief without compromising stability.

The coir’s naturally open structure enhances airflow, helping maintain a cool, fresh sleep environment. This breathability is complemented by your choice of two premium covers. The Vegan Cover uses advanced probiotic technology to create a naturally clean, allergen‑reducing surface, while the Organic Cover features GOTS‑certified cotton and wool for superior moisture regulation and temperature balance.

Ideal for sleepers seeking a supportive, breathable mattress with a balanced medium–firm feel, the Demko Organic Coir Mattress DeLuxe C offers pure materials, thoughtful engineering, and long‑lasting comfort — a stable foundation for restorative sleep.
