The Complete Wool Bedding Set contains all-season bedding pieces that are filled with Climate Beneficial Wool batting and covered in 100% certified organic cotton fabric. Batting is a layer, or sheet, of wool that provides a stable filling that doesn't move inside the comforter. Enjoy the natural benefits of wool bedding for better, more comfortable sleep. Each wool bedding set includes a comforter, mattress topper, and pillows. Our Wool Comforter can be used with a duvet, comforter cover, or alone. Knotted approximately every nine inches, the comforter provides easy temperature regulation in any weather for improved sleep. The mattress topper, approximately 2.5 inches thick, provides you with added comfort along with the natural benefits of wool. It is knotted approximately every nine inches with elastic straps to secure it. The Wool Bedding Sets also include 1-2 wool pillows, sized appropriately for your set. Each of our wool pillows features wool batting that compresses about 1/3 of the original loft, providing firm support and gentle cushioning.
