Demko Organic Coir Mattress ExtraLuxe C | Extra Firm Vegan Tencel GOTS Organic Cotton

The Organic Coir Mattress is engineered for individuals who demand extreme firmness without compromise. Constructed entirely from organic coir fibre with two thin layers of latex, it stands as one of the firmest sleep surfaces available on the market today. This mattress is specifically designed to provide unyielding skeletal support, making it the ideal solution for those who find conventional mattresses too soft and require a stable, rigid foundation for their spinal health.

At its core is densely packed organic coir — a natural fibre derived from coconut husks — renowned for its durability, breathability, and exceptional load‑bearing strength. This robust structure maintains a perfectly level plane throughout the night, even for heavier sleepers, ensuring consistent spinal alignment without sinking, dipping, or compression. The addition of a thin layer of organic latex on both the top and bottom enhances comfort while preserving the mattress’s uncompromising firmness.

This stable, non‑sinking design also promotes an open‑airway sleeping position and prevents the muscular strain associated with surface sagging, making it a reliable long‑term choice for anyone needing a truly rigid sleep surface.

To complement its robust core, the mattress offers two premium cover options tailored to individual health priorities. The Vegan Cover utilises advanced probiotic technology to maintain a sterile, allergen‑free environment, while the Organic Cover features GOTS‑certified Merino wool for superior temperature regulation. Both systems enhance airflow, ensuring that even with its dense construction, the mattress remains cool, breathable, and fresh.
