Nominated as a finalist for the “Healthiest Crib Mattress” in the Cribsie Awards, the Natural I uses absolutely no metals and plastics in its innovative design. Instead, this 5” thick crib mattress features natural and renewable component materials, coir fiber made from coconut shell husks, bonding from an all-natural latex, and natural cotton cushioning layers. These unique components are wrapped inside a ulta-soft, certified organic cotton cover. Along with being ecologically-friendlier, the cover is waterproof, tear-resistant, and hypoallergenic. Like all Colgate mattresses, the Natural I is GREENGUARD ® Gold certified, CertiPUR-US ® certified, CPSIA compliant, and compliant with all federal and state flammability requirements – without the use of fire retardant chemicals. Your Natural I is proudly handcrafted in the USA by Colgate, The Crib Mattress Specialist®, a family-owned and operated business dedicated to baby’s safety since 1955.
