Frequently asked questions
What fill power should I look for in a goose down comforter?
Fill power measures the loft and insulating ability of down. For a Cal King comforter, 600-650 fill power is good for general use, while 700+ offers premium warmth and fluffiness. Higher fill power provides more warmth with less weight.
Are goose down comforters hypoallergenic?
Goose down itself isn't hypoallergenic, but many comforters are treated or encased in allergen-proof covers. Look for RDS-certified products that are washed to remove dust and allergens. Some owners with mild allergies tolerate them well.
How often should I wash a goose down comforter?
Most manufacturers recommend washing every 1-2 years, or if the comforter becomes soiled. Use a mild detergent and dry on low heat with wool dryer balls to restore loft. Always follow care instructions to avoid damage.
What is the best material for the outer shell?
Cotton shells with a thread count between 233 and 300 offer a good balance of softness and down-proofing. Higher thread counts prevent feather poking and are quieter. Organic cotton is preferred for environmental reasons.
Can I use a duvet cover with a goose down comforter?
Yes, a duvet cover protects the comforter and extends its life. Look for comforters with corner loops or ties to secure the cover. A cover also makes cleaning easier, as you only need to wash the cover more frequently.
