Sferra’s down collection presents various options of white goose down fill power: Buxton (600+ European), Somerset (700+ Polish), Cardigan (800+ Siberian), and Snowdon (900+ Canadian). 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. With a weight and a loft for everyone, one will be just right for you! Duvets offered in Light, Medium and Heavy. All duvets feature a baffle box construction and are finished with a decorative piped edge. All duvets have corner loops for a balanced overall experience once the duvet is encased within a cover.
Most down comforters can be washed in the washing machine. We recommend using cold water and the gentle cycle, and using a gentle detergent such as our Down Wash. Dry cleaning should be done by an experienced dry cleaner who is familiar with down. Down pillows should be spot cleaned. To extend the life of your down pillows, we recommend using pillow protectors.
