Frequently asked questions
What does 15 tog mean in a duvet?
Tog measures thermal insulation; 15 tog is the highest common rating, ideal for cold winter bedrooms. Higher tog means more warmth, but materials and fill also affect actual warmth.
Is a 15 tog duvet too warm for everyone?
Not necessarily; it's designed for cold sleepers or unheated rooms. If you sleep hot, consider a lower tog or a breathable down duvet with cooling properties.
How long does a down duvet last?
With proper care, a quality down duvet can last 10-15 years. Air it regularly, wash every 3-5 years, and use a duvet cover for protection.
Can I wash a 15 tog down duvet at home?
Yes, but check the care label. Most down duvets are machine washable on gentle cycle with wool wash, then tumble dry low with clean tennis balls to restore fluffiness.
What fill power should I look for?
Fill power of 600-800+ indicates quality down. Higher fill power (e.g., 700+) means more loft and warmth with less weight, leading to better insulation and durability.
The verdict
The Slumber Down White Goose Down Duvet 15 Tog is our overall winner for its premium materials and certifications. For versatile year-round use, consider the Silentnight All-Season Duvet, while hot sleepers should opt for the Charisma Cooling Duvet for better temperature regulation.
