Densely woven wool from organically raised sheep is as soft as a favorite blanket. The natural water resistant properties of the wool will keep your mattress protected from moisture yet continue to allow air flow through your bed. You will sleep wonderfully as the wool allows for air flow and an added layer of comfort below you. As a mattress pad it will fit nicely beneath sheets and since it is all natural from organically raised sheep it will most likely not be a skin irritant and be as comfortable and as soft as cotton. Can be ordered as small as a crib sized or as large as a California King.
