NUTRITIONAL INSTITUTETM Organic Futons have nothing in common with the typical futons made by other manufacturers. That's because our futons are ultra-comfortable (NOT uncomfortable like most futons) and they're completely natural and chemical-free . The secret that makes our futons so comfortable lies in the two-inch natural rubber core, which is surrounded by multiple layers of 100 percent organic carded-cotton batting. It has an organic cotton cover that is quilted with wool, which lends flame-retardant and dust-mite-repellent properties, not to mention luxurious comfort. Use it as a sofa, a mattress or both!
