Frequently asked questions
What is the ideal fill power for a goose down duvet?
Fill power measures the loft and insulation efficiency. For a super king duvet, 700 to 800 fill power is considered excellent, offering good warmth without excessive weight. Higher fill power (800+) provides more loft and is lighter, but often comes at a premium.
What does the Responsible Down Standard (RDS) certify?
RDS certification ensures that down and feathers come from animals that have not been subjected to unnecessary harm. It verifies ethical sourcing from geese and ducks, including no live-plucking or force-feeding. Look for RDS logos on packaging.
Can a super king goose down duvet be machine washed?
Many duvets can be machine washed on a gentle cycle using a mild detergent, but always check the care label. Most require professional dry cleaning for best longevity. Frequent washing can reduce loft; using a duvet cover protects it.
What is the best tog rating for a goose down duvet?
Tog rating indicates thermal insulation; higher togs are warmer. For year-round comfort, many opt for a 9 tog medium, or an all-seasons set with separate summer (4.5) and winter (13.5) layers. Personal preference and room temperature matter.
How do I choose between a goose down and duck down duvet?
Goose down generally has higher fill power and larger clusters, offering better loft and insulation for the same weight. Duck down is more affordable but may be less warm and have a slightly stronger odor. Both are quality options when certified.
