2-STAGE MATTRESS: The convertible Dri-Tec Performance Mattress is a 2-stage lightweight, convertible mattress that grows with your baby. The infant side of the mattress is made with a safe and firm surface, while the toddler side is softer and more responsive to support your baby's growth. BREATHABLE AND COMFORTABLE: The Dri-Tec, moisture-wicking cover, and breathable mesh sides allow for maximum airflow in and around the mattress for your child. HEALTHY SLEEP: A night of peaceful sleep awaits your little boy or girl. The noiseless and waterproof mattress cover protects the crib mattress from stains and fluids for a clean and healthy sleep environment. EASY TO CLEAN: Machine wash the cover on a cold, gentle cycle and then tumble dry on low heat to ensure it stays fresh and lasts for years to come.
