Finding the right duvet inner for every season
Understanding TOG Rating: How warmth is measured
TOG, short for Thermal Overall Grade, measures insulation, not weight or thickness. It is why a light goose down duvet can outperform a heavier synthetic one, and why the higher the TOG, the warmer the night's sleep.
Find where you fall on the scale, and let that be your starting point.
Understanding Fill: Choosing what's right for you
From lightweight microfibre to fine goose down, the fill inside your duvet determines its warmth, weight and feel. Here's what sets each apart, so you can choose with confidence.
Microfibre
Microfibre
Fine synthetic fibres that mimic down's softness and loft at a fraction of the price. Hypoallergenic, washable at home, and free of animalproducts.
Allergies, children, guest rooms, vegan households.
Feather & goose down
Feather & goose down
Feathers give structure, down traps the air that keeps you warm. The result is light, warm and breathable, and it lasts for years with the right care. Ethically sourced. Cold sleepers, luxury buyers, gifts.
Hungarian goose down
Hungarian goose down
The most warmth for the least weight. The percentage on the label, 40% or 90%, is how much of the fill is pure down rather than feather; higher means lighter and warmer. Buying once, properly.
Australian wool
Australian wool
Regulates temperature rather than only insulating, so it stays comfortable across seasons. Naturally resists dust mites. Heavier, and it needs gentle care.
Natural-fibre and all-season sleepers.
When to replace your inner
A good-quality duvet inner can last for many years with the right care. As a general guide, consider replacing your duvet every 5–10 years, or sooner if it has lost its loft, warmth or ability to distribute filling evenly. Regular airing and following the manufacturer's cleaning instructions can help extend its life.
Understanding Fill: Choosing what's right for you
A little care goes a long way. The right washing and drying approach keeps your duvet inner fresh, fluffed and performing at its best, whatever fill you've chosen.
Washing and care by fill type
Every fill behaves a little differently in the wash. Knowing what's inside your duvet is the first step to keeping it clean and in good condition for years to come.
Microfibre & cotton-rich
Microfibre & cotton-rich
Machine washable. Gentle cycle, cool or lukewarm water, mild liquid detergent, tumble dry low with dryer balls. Two or three times a year is plenty.
Feather & down
Feather & down
Dry cleaning is safest. If you wash at home: gentle cycle, cool water, a down-specific detergent, and tumble low with dryer balls until completely dry. Avoid top-loaders with agitators. Once every year or two.
Wool

Cold gentle or wool cycle, then line dry straight away — never wring or twist it. Dry cleaning is recommended for most wool inners.
