Collection: Coconut Coir

Coconut coir is one of the most effective natural materials for supporting a breathable, low-tox sleep system. Made from the fibrous husk of coconuts, it creates a firm, springy layer that lifts your mattress, keeps air moving underneath, and helps manage moisture in ways solid boards and synthetic foams simply can’t. Whether you’re drawn to Japanese-inspired floor setups or classic bed frames, coir adds a quietly powerful layer of support and ventilation.

In mattresses, coconut coir is often used as a stabilizing, naturally resilient core that complements the comfort of cotton, wool, and latex. When you choose a coir-based design from our mattress collection or upgrade to options in the natural mattress lineup, you get a firmer, more grounded feel with better airflow through the center of the bed. The result is a supportive coir mattress that stays drier and more temperature-balanced, especially in humid climates or on solid surfaces.

Under the mattress, coconut coir truly shines in foundations and bed rugs that sit between your sleep surface and the floor or platform. A coconut coir mattress foundation or low-profile coir insert helps distribute weight evenly while letting air move freely under the bed, and our natural coir bed rugs are perfect for floor setups or solid bases that need extra ventilation. These pieces are especially helpful for futon-style beds, shikibutons, and natural fiber mattresses that perform best with consistent airflow underneath.

Coconut coir layers also pair beautifully with minimalist, low-to-the-ground designs. If you’re building a Japanese-inspired sleep system, combining a breathable coir base with floor bed setups or incorporating it beneath tatami mats and platforms helps keep the underside of your mattress or shikibuton drier, fresher, and less prone to trapped humidity. Over time, this natural ventilation can play a key role in maintaining both comfort and longevity for cotton and wool-rich sleep surfaces.
