Our Down and Feather inserts are well filled and covered with natural cotton down-proof cover. The higher the % of down the smoother the feel and more expensive they become. We strongly recommend buying an insert 2″ bigger than the cover , so that the corners will be well filled. They are available in most sizes, and shapes (round, neck rolls, hearts, and rectangles). Unfortunately, due to limited space on the web site, we list only our most popular sizes. If you need anything else e-mail us (contact us) or call 305-634-3415 (9am to 4pm est.).
