With a removable, machine-washable, certified organic cotton encasement and PLA batting, this MADE SAFE® certified pillow ensures fresh, clean comfort. PLA is a plant-based synthetic fiber, and Naturepedic formulates this style exclusively from non-GMO sugarcane. The fiber is both resilient and moisture-wicking for reliable support and a cool, comfy sleep. Best of all, there is no polyurethane foam, no polyester fill, and no chemical flame retardants!
