These comforters are made in the USA. They have a 50/50 polyester cotton shell and are filled with 100% polyester. Machine Washable and dry on low or you can dry clean them. These are quilted so the fiber inside does not shift. I have washed mine repeatedly and never had any issues. I put the dry cycle on the permanent press setting and I take it out as soon as it is dried and spread it out on my bed and I have never had to iron my comforter.
Queen King measures 90 x 108 inches so it can tuck in on the sides be long enough to cover the pillow. These are made for hard Wood Sided Waterbeds.
