Our Endura Light Memory Foam Cushion is on the firmer side and consists of high-density visco-elastic memory foam, a breakthrough in foam technology. Covered in a great fabric, CoolMax, which amongst other advantages, it’s soft on the skin, breathable, durable, and assists to keep the pillow moisture-free. Our quality memory foam is temperature-sensitive. In very cold temperatures, this product initially, is a lot firmer. Once the foam has been exposed to a person’s body heat and room temperature, it will become more supportive and supple.
