Counting sheep isn't the most effective way to achieve a good night's sleep, especially when you're not even old enough to count; but you can still ensure your little one gets the sleep she or he needs, with the Babyletto Pure Core Crib Mattress. This mattress is both well constructed and constructed well, giving you peace of mind while your baby gains peace of body. This innovative mattress relies on laminated thin layers of polyester and air to construct a lofty and firm sleeping surface, as recommended for crib mattresses by the American Academy of Pediatrics. And the accompanying mattress cover is constructed to breathe easily beneath a sleeping infant to help prevent overheating and reduce the risk of SIDS. Also designed to resist dust mites and other allergens, using natural, nontoxic materials - this mattress and cover set is free of glues, dyes, chemical flame retardants, foam, vinyl, allergens, phthalates, PFCs, synthetic latex, and off-gassing materials, giving you confidence that your baby is safely supported all night, every night. Nothing gives a parent more peace of mind than the knowledge of their baby's security, but you'll also rest easy knowing that your child's nursery is conscientiously constructed. Without the use of animal byproducts, the vegan mattress is also entirely recyclable.
