I Love the fact that it is machine washable, and can be either line dried, or dried in the dryer. "Not sure how line drying would work, since my mom purchased the 25 lb one, for my 20 year old severely autistic son." The poly-fill does come through, and pill all over the blanket, but I do not mind. My son has been sleeping much better with this weighted blanket. After 20 year's, it is a "God send!" Thank You for making our lives a little easier.
