Organic sleep presents you with one of the only petro-chemical free futons available today. The Pure Comfort organic mattress is made with 100% certified organic cotton, virgin wool and 733 pocketed steel coils. We rated this mattress as extra soft. This fabulous supportive and comfortable natural mattress is my personal favorite as it is made with organic cotton toppers and contains no petro-based foam. This futon mattress has 733 individually pocketed coils that are each 3 inches in height. The height and construction of these coils help you sleep stronger and longer. Marshall's encased coils practically eliminate motion transfer, and its fortified recycled steel springs and long-lasting fabric provide overall surface consistency and improved weight distribution. These coils are surrounded by 100% pure American virgin wool. Wool is super strong, it 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. The crimp in the wool adds springs and bounce to this organic mattress. The capacity to absorb makes wool a "temperature regulator" making it cool in the summer and warm in the winter. The wool is topped with USDA certified organic cotton giving this futon mattress a superior surface for you and your guests. The Pure Comfort organic mattress is ideal for everyday use in any room of your home. You and your guests will sit and sleep well knowing they are contributing to the health and welfare of all Americans. This mattress is perfect for bedrooms, quest rooms, home office, dorm rooms and all living areas.
