Organic sleep presents to you the Perfect Comfort futon mattress. The heart of this mattress is wool, with 100% certified organic cotton and 4 inches of firm soy-based foam. This futon mattress is rated firm. We combine 3 ingredients to make this firm and supportive mattress: long fiber staple organic cotton, American grown virgin wool and eco-friendly bio-flex hybrid soy foam in a high density. This extra-firm firm density eco-friendly soybean-based foam has greater support factors, enhanced "hand" and tactile properties, Excellent Tear/Tensile strength plus Supreme cell integrity for longer life. The benefits of wool in a mattress are many, wool can be bent back on itself more than 20,000 times without breaking, compared to about 3,000 times for cotton and 2,000 times for silk therefore it is resistant to tearing and helps add years of life to your mattress. Wool is also hygroscopic fiber; it takes up moisture in vapor form. Tiny pores in the epicuticle make the fiber semi-permeable, allowing vapor to pass through to the heart of the fiber. Wool can easily absorb up to 30% of its weight in moisture without feeling damp or clammy. The crimp in the wool adds springs and bounce to this futon mattress. The capacity to absorb makes wool a "temperature regulator" is most beneficial in any mattress. This futon mattress is suggested for every day sitting and sleeping with a platform bed or convertible futon sofa bed. The Perfect comfort futon mattress is ideal for everyday use in any room of your home where you require firm support. This mattress is perfect for bedrooms, quest rooms, home office, dorm rooms and all living areas.
