Demko Organic Coir Mattress Proluxe C | Firm Vegan Tencel GOTS Organic Cotton

The Demko Organic Coir Mattress Proluxe C is crafted for sleepers who want firm, natural support with the flexibility to fine‑tune their comfort over time. Designed with a modular 5‑layer structure, it offers a stable, breathable, and adaptable sleep surface made entirely from certified organic materials.

Crafted with three layers of GOLS‑certified organic latex and two layers of breathable GOTS‑certified coir fibre, this mattress offers a firm, balanced feel. Slightly softer than the Proluxe B, its modular 5‑layer construction allows you to rearrange the layers to fine‑tune firmness, making it a practical solution for evolving comfort preferences.

The coir layers — derived from coconut husks — provide natural rigidity, durability, and excellent load‑bearing strength. Their non‑sinking structure keeps the spine level throughout the night, preventing dips and compression. The GOLS‑certified latex layers add responsive cushioning while maintaining the mattress’s firm, supportive character.

This naturally ventilated design promotes airflow through every layer, helping maintain a cool, fresh sleep environment. Your choice of premium covers further enhances breathability. 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 adults seeking firm, organic support with the ability to personalise firmness, the Demko Organic Coir Mattress Proluxe C delivers pure materials, structural stability, and long‑lasting comfort — a mattress that adapts as your needs evolve.
