Ideal for babies who suffer from allergies or are in need of extra orthopedic support, the Baby Steps Blended Latex Crib Mattress features a blended latex core and an unbleached, untreated cotton cover. Latex is an excellent choice because it conforms to the body, providing superior support and pressure point relief. In addition, latex is naturally hypoallergenic and resistant to mold, mildew, and dust mites. This mattress is also available with a layer of quilted Pure Grow Wool™ and organic cotton.
