Our organic wool puddle pads use our certified organic wool which is carded and certified organic during this processing by Oregon Tilth. It is then felted at a west coast felting mill. This pad naturally resists liquids to protect your mattress. No polyurethane or other synthetic backing is put on our wool. Our puddle pads are not quite as soft as our Wool Moisture pads but the price is a bit better. Both pads are from the United States. Adult sizes have elastic straps and all are machine hand wash cycle or delicate cycle or hand wash only since we oversize ours to allow for the shrinkage; hang dry - not in direct sunlight .
