Deluxe pillows feature attractive Certified Organic Cotton European Damask outer fabric that is durable and soft. The wool fill comes from healthy, organically raised living sheep that enjoy a stress-free life of organic food, clean environment, and good health. The resulting fleeces are sorted and washed with only hot water and vegetable-based soaps (no detergents, chemicals, or chlorine bleach, resulting in wool fibers that are strong and springy). Then these fibers are carded in a chemical-free certified organic carding facility. Other manufacturers cannot guarantee wool purity as they send their wool to be carded at regular carding facilities.
