All of our crib mattresses are made with the purest ingredients we could find. We use wool processed organically so that you know there are no extraneous chemicals or fibers (most "organic" wool is processed in plants that process other fibers, so it gets chemicals and fibers in it. To know for sure, you would need to get and actual test result from a lab that tested their CARDED wool). The rubber is also tested for toxic vocs at a third party lab. We do not use ANY synthetic, nondisclosed hidden fibers as our competitors do. We want you to have total purity. Beware of so called certifications. Organic has to be 95% pure to be called organic, Green Guard allows even more contaminants and chemicals.
