A down comforter is a wonderfully soft, warm, light quilt, filled with down from waterfowl like geese or ducks. Its breathable insulation means that a down comforter can be warm in winter and cool enough for summer. When investing in a down comforter there are a few things to consider to ensure you’ve made a good choice that will suit your needs.

The first consideration is the down itself. Down feathers come from the fluffy undercoat and do not have a central quill. Because down is naturally curly, clusters of down form insulated pockets that hold in heat while allowing air to pass, or the body to breathe. Down from adult birds is larger and forms better clusters. Down clusters are separated by baffles sewn into the quilt, to keep the down properly distributed.

Down comforter packaging might only advertise the weight of the fill. This isn’t necessarily a good indication of the warmth or quality of the down comforter. A down comforter can be filled with many different types of down. A less expensive down comforter might have down mixed with feathers. Top feathers add to weight, yet have a hard central quill, are flat, and detract from the softness and insulation properties of down.

The fill power rating of a down comforter is a much better indicator of quality. Fill power describes the expansion properties of one ounce of down in cubic inches. In other words, if the type of down used is from adult birds, one ounce, when fluffed, will loft and expand to fill a larger cubic space than one ounce of smaller down. The higher the fill power, the warmer and fluffier the down comforter.

For people who require an electric blanket or several warm blankets, a fill power rating of 600 indicates a very warm, high quality, down comforter. For those with naturally warm blood who toss blankets aside, lower fill powers will suit better and be less expensive. However, a down comforter with a very low fill power will not be fluffy, and will not have good insulation properties.

The other major consideration when buying a down comforter is the quilt’s thread count. A low thread count allows down to escape through tiny holes in the weave of the fabric. Higher thread counts mean more tightly woven fabrics that will keep the down contained. Material with a high thread count might also allow the down comforter to be washed in a large, commercial machine per manufacturer’s instructions.

Finally, a down comforter is smaller than a bedspread or blanket. A down comforter packaged as a “Queen” will cover a Queen mattress, but will only drape over the mattress’ sides a few inches or so. If you’d like the down comforter to drape further, you’ll have to buy a larger comforter. If you have a King bed, this isn’t possible, but a dust ruffle might help. Remember too, that a California King bed is longer but narrower than a Standard King.

Though a quality down comforter is more expensive than a blanket, it is also something you will enjoy each and every night when you slip into bed. A good quality down comforter should last years, giving you a solid return on your investment.
