Let your mattress breathe. We designed our Coconut Coir Mattress Pad to be the ideal base for mattresses on surfaces lacking airflow. With durable, long-lasting, natural coconut fibers, lightly mixed with GOLS-certified organic latex, the breathable pad allows air to flow underneath your mattress. Not enough airflow under your mattress can cause moisture to build up, especially in humid locations. Our pad supports mattresses of all weights and sizes. And its flexible nature means it fits with adjustable bases.
