Give your favorite duvet cover a fresh new fill with this must-have plush insert. Ideal for those with allergies, this down-alternative design is made from hypoallergenic microfiber polyester that won't cause sneezing or irritate the skin. A baffle-box construction allows for an even distribution of fill, so that this piece is equally warm all over without bunching. It's an all-season design that can be used year-round. And a neutral white hue means it effortlessly blends with any cover without showing through. It's even machine-washable for quick and easy cleaning – and it's perfect for any bedroom.
