Luxury Comforters What makes a comforter luxurious? We think 100% Hungarian or Polish white goose down surrounded by 354 thread count German sateen cotton ticking is incredibly luxurious, warm and comfy. Plus our down comforters have luxuriously high fill powers, which means they feel light as a feather but are just as warm as heavier blankets. To learn more about down, fill power and other important things to know about down; take a look at our down information page. We also have comforters with down-alternative filling as well as wool, which provides balanced thermal insulation and is naturally hypoallergenic.
