This is it – the most recognized foam crib mattress by name in America. The Classica I was designed with your littlest one in mind, providing an extra firm, safe, and comfortable sleep environment for your baby. The 5” thick foam is CertiPUR-US® certified for quality and is extra firm to provide the necessary support for baby’s proper development. The foam is covered by an easy-to-clean mattress cover, which is triple-layered reinforced, waterproof, hypoallergenic, and tear-resistant. Additional features include strong cloth binding seams for mattress longevity and durability. While multiple side eyelet vents help increased airflow throughout the mattress. Parents will appreciate the Classica I’s lightweight, square-cornered design, which fits snuggle inside all standard-size American cribs and toddler beds. Like all Colgate products, the Classica I is GREENGUARD ® Gold certified, CPSIA compliant, and compliant with all federal and state flammability requirements, without the use of fire retardant chemicals. Your Classica 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.
