The Colgate Eco Classica III is an expertly engineered dual-firmness crib mattress, packed with 6” of eco-friendlier foam made with sustainable plant oils. The extra firm side is engineered to provide the firmness infants need for proper support and development, while the less firm side provides – when the time comes — the comfort toddlers prefer. This is all wrapped snugly inside an ultra-soft certified organic cotton cover, which is waterproof-backed to ensure the mattress stays dry while baby’s skin remains closest to organic cotton. The Eco Classica III is designed to last throughout the infant and toddler years, with inverted seams to ensure mattress durability. Like all Colgate mattresses, the Colgate Eco Classica III 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 Eco Classica III 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.
