My First Mattress is no ordinary bed. Our innovative design with duo-layered construction fits your child's needs from infancy into childhood and is suitable for newborns and children up to 5 years old. The mattress has two layers of foam; high density foam and a layer of memory foam. We've combined the needs of both infants and toddlers into one mattress that meets safety standards of a crib mattress, but can also transition to a toddler bed as your child grows. Simply flip the mattress over depending on your needs. Removable and washable cover. Hypoallergenic; prevents allergens from clinging to the mattress. For infants, use the firm high-density foam side that will provide your baby with the support they need. Mattress meets safety standards as defined by the CPSC and American Society for Testing and Materials crib mattresses. The square corners provide a snug fit in your crib. When your child becomes a toddler, simply flip the mattress over to the memory foam side and use in their toddler bed. The comfortable memory foam layer contours to the body for even weight distribution.
