Frequently asked questions
What fill power should I look for in a down duvet?
Fill power measures loft and insulating ability. For a full bed, 600-700 fill power is ideal for all-season use. Higher than 700 is warmer and lighter but more expensive. Lower than 600 may feel heavy and less warm.
How do I choose the right warmth level?
Consider your bedroom temperature and personal sleep temperature. Lightweight is for hot sleepers or summer, midweight for all-season, and heavyweight for cold climates. Many duvets offer multiple warmth options.
Are down duvets hypoallergenic?
Most quality down duvets are processed to remove allergens, but they may still bother severe allergy sufferers. Look for 'hypoallergenic' labels or consider down alternative duvets if you have allergies.
How do I care for a down duvet?
Machine wash in cold water on gentle cycle, using a down-specific detergent. Tumble dry on low heat with dryer balls to restore loft. Dry cleaning is also an option, but may reduce lifespan.
What certifications matter for down duvets?
Downpass or Responsible Down Standard (RDS) ensure ethical sourcing. OEKO-TEX Standard 100 certifies no harmful chemicals. Organic cotton shells indicate fewer pesticides.
