There's nothing more natural than childbirth, and the Babyletto Coco Core Air Crib Mattress helps you bring your baby into a naturally safe home. This innovative mattress relies on natural materials to construct a sleeping surface for your little one. Its inner core is made with coconut husk fibers that are coated in natural, hypoallergenic latex and surrounded by thin layers of polyester batting and covered in a cotton-modacrylic outer core. This produces a lofty, firm, and environmentally sustainable construction perfect for your baby's crib. Free of glues, dyes, chemical flame retardants, foam, vinyl, allergens, phthalates, PFCs, synthetic latex, and off-gassing materials, this nontoxic mattress gives you confidence that your baby is safely supported all night, every night. Without the use of animal byproducts, the vegan mattress will also help you rest easy, knowing that your child's nursery is conscientiously constructed. And because the mattress and cover are designed to breathe easily beneath a sleeping infant, they help prevent overheating and reduce the risk of SIDS. The water-repellent cover keeps baby from soaking down through the mattress, making it simple to keep baby's nursery clean and healthy.
