This is pure delight. Imagine a soft lambswool sheepskin but minus the skin. Introducing a sustainable lambswool made by weaving the organic Merino wool into a backing or organic cotton. Wool fibers are approximately 1.5" high. This is a wonderful alternative to sheepskin, it is 100% organic and the softness is unmatched. Place the Happy Lamb Fleece on top of your mattress. Small sizes are great for traveling away from home. It is very therapeutic for anyone who has to spend a long time in bed (i.e. bed sores) and can be helpful for people dealing with fibromyalgia. It is incredibly healing, breathable and great for circulation.
