Crafted from organic cotton and premium Naturepedic foam, our lightweight mattress provides healthful support from birth through the toddler years. The 2-in-1 design pairs a firm side that's ideal for newborns with a more cushioned side that's just right for older children, its lighter weight allowing for quicker and easier bedding changes. Waterproof upholstery and a washable organic-cotton cover ensure easy care and lasting comfort.
