Ideal for babies who suffer from allergies or are in need of extra orthopedic support, the Baby Steps Latex Quilted Crib Mattress features a 100% pure latex core with a layer of organic cotton and wool quilted to an organic 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.
