A naturally liquid resistant felted wool pad to keep your twin xl mattress protected! Made with untreated organically processed wool from new zealand and felted using strictly water. Great for keeping your mattress extra safe from most kinds of liquids or stains. If one is breast feeding or going through menupausal temperature irregularities this pad works especially well by itself. The puddle pad is thicker and less soft than the moisture pad due to it being slightly less felted. It is also more economically priced. Although the wool used is not certified organic, we have found the wool to be of equivalent purity to certified organic wool. Minimal washing is needed due to the natural bacterial and mold resistance of wool. Machine wash on delicate and hang dry. Clean only when absolutely neccessary. Add 1/4 cup of vinegar to the load to increase softeness. This pad features natural elastic straps to hold it in place on the bed. We do recommend using this pad in conjunction with our organic cotton quilted pad for ultimate protection and ease of use (the organic cotton quilted pad would absorb the liquid and is machine wash and dry). It would go on top of the moisture pad but still under the fitted sheet(so the order would be from botton to top: mattress, moisture pad, cotton pad, and then fitted sheet). Made here at our San Diego, CA Facility. Ships within 1-2 business days.
