Our dual-stage crib mattress adapts as your baby grows, with an extra-firm side for infants and a plush side for toddlers. Made in the USA of eco-friendly and hypoallergenic materials, it's GREENGUARD Gold certified and free from VOCs, with no off-gassing or toxic emissions. It features an organic cotton cover that's water repellent and machine washable. The breathable design helps regulate temperature, and around the entire mattress perimeter is a 2” firm-edge guard to support little ones as they begin standing. Perfect for all standard cribs and toddler beds, including every Oeuf design.
