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 of organic cotton. Wool fibers are approximately 1.5 inches high and weigh 33 ounces per square yard. This is a wonderful alternative to sheepskin. It is 100 percent organic and the softness is unmatched. Place the Happy Lamb Fleece between your mattress and fitted sheet, no straps needed. It is very therapeutic for anyone who has to spend a long time in bed. It is incredibly healing, breathable and great for circulation. Spot Clean Only.
