What Is the Importance of a 2-Stage Design in Sealy Crib Mattresses?
A 2-stage design in Sealy crib mattresses refers to a dual firmness construction that provides distinct sleeping surfaces for infants and toddlers. One side is firmer, designed to support the developing bodies of infants, while the other side is softer and more comfortable for toddlers transitioning to a larger sleep surface.
According to the American Academy of Pediatrics, a firm sleep surface is crucial for reducing the risk of Sudden Infant Death Syndrome (SIDS) and promoting safe sleep practices (AAP, 2022). The 2-stage design offered by Sealy mattresses aligns with these safety recommendations by ensuring that the infant side provides adequate support while maintaining a safe sleeping environment.
