This water-repellent mattress pad is made from 100% organic cotton. On the back side, the mattress pad has a layer of non-food natural cellulose, this material is used in the manufacture of baby diapers. It works like this: when a liquid accidentally falls on the bed, it penetrates the cotton fabric of the mattress pad, but the cellulose layer does not allow the liquid to pass onto the bed. Your bed will be ecological, clean and dry. Such a cover creates a breathable layer between the bed and the sleeper's body, that is, no matter how synthetic your bed or blanket is, the natural coating prevents the "thermos effect", you will not have to sweat in bed and your sleep will be comfortable.
