When your delicate little one finally arrives in the world, trust LA Baby's Two in One Organic Cotton Orthopedic Mattress to keep him or her safe and comfortable. It's constructed with multiple layers of soft, safe, 100% organic cotton that's pure and trustworthy, with no chemical foams or fillers. It's reversible, adjusting to your growing baby's needs. One side has the extra firm support recommended for newborns, while the other side provides additional padding for comfort when your baby becomes a heavier, and more dynamic, toddler. That strong support comes from a core made of 260 coils of heavy duty 15 1/2-gauge tempered steel surrounded by a border of 6-gauge steel rods for even greater support and strength. It's so tough the mattress comes with a 25-year warranty, and it's flame retardant, meeting all applicable safety standards, including the strict requirements of the California Bureau of Home Furnishings.
