Q: What does fill power mean in down comforters and pillows?
A: Fill power is a measurement of efficiency; the higher the fill power number, the better the down and the greater the insulating value. The fill power measurement represents the number of cubic inches filled by an ounce of down.
Fill power is directly related to the size of the down cluster. Large down clusters occupy more space than smaller down clusters. The higher the fill power, the larger the clusters, and thus, the more air that is trapped between the clusters. The trapped air is what gives down its insulating properties.

The size of the bird and the climate in which it lives, determines the size of its down cluster. The colder the climate, the larger the down cluster required to keep the bird warm. For example, it is colder in Canada than it is in Hungary. Therefore, the birds need larger down clusters in Canada to stay warm.
We carry luxury bedding from Scandia Down. Now that we are wrapping up this holiday season, it’s time to think about more practical matters: cold winter nights. Even though our Pacific northwest days are slowing getting longer again, we’ve got three months of winter ahead. Scandia Down is what gets me through the winter: it doesn’t really matter how dark or gloomy it is outside as long as I know I can curl up inside a warm bed.
And stay tuned for our White Sale, coming up in the new year. Details soon…
