A great option for moms looking to offer an organic product but still looking for waterproofing. Our quilted play yard mattress pad is made with a surface layer of 100% organically grow Cotton with an allergy barrier that is a soft knit fabric backed with ultra thin breathable, waterproof polyurethane membrane. Specially designed patented safety stay on corners and extra deep sides keep this mattress pad in place at all times, no matter how thick the mattress. The mattress pad has an envelope design that wraps around the bottom of the play pen mattress that prevents it from coming off. There are no attachment or straps that come with the product. You can never have too many mattress pads, so keep several in your linen closet. It is sized to allow for shrinkage and the full skirt is designed for a snug fit. Machine wash and dry. The OE Blended Standard applies to products that use a blend of organic and non‐organic cotton or other fibers, and contain a minimum of 5% organic cotton. The OE Blended requires that the organic cotton is grown on certified farms and sets criteria for proper handling and tracking of the organic cotton through all steps of textile processing.
