King size organic cotton down feather comforter is machine washable. Can use it year round on bed , it has a light feel to it not heavy. The down feathers are light fill and no quills are poking out and stabbing you while you sleep. Perfect amount of down fill for the person who wants a light weight comforter. I have a queen bed but I ordered the king size so I can have over hang on my bed. Bonus for me it comes in a really nice cotton storage zipper carrying case. 5 stars Wayfair! I recommend this for lovely topping for any bed.
