Quick answer: which duvet filling is right for you?
Choose goose down for the lightest, warmest feel (best for cold sleepers), Australian wool for all-season temperature regulation (great for hot, cold and allergy-prone sleepers), mulberry silk for the coolest, lightest option (best for hot sleepers and summer), or a down & feather blend for warmth at a friendlier price. All of our fillings are natural and, with proper care, last 10–20 years.
| Filling | Warmth | Best for | Care |
|---|---|---|---|
| Goose down | Warmest, lightest | Cold sleepers who want cloud-like warmth | Dry clean |
| Australian wool | All-season, adaptive | Hot, cold & variable sleepers; allergy-prone | Spot clean / air |
| Mulberry silk | Coolest, lightweight | Hot sleepers & summer | Machine washable |
| Down & feather | Warm, a touch heavier | Value seekers wanting natural warmth | Dry clean / spot clean |
Goose down is the gold standard for warmth-to-weight — it traps body heat in lofted clusters, so a down duvet feels light yet exceptionally warm. Quality is measured in fill power: higher numbers (550 up to 850) mean more warmth for less weight. Best for cold sleepers and Canadian winters. Explore our goose down duvets, including the 850 fill power Glucksburg.
Wool is the all-season all-rounder. It naturally regulates temperature — wicking moisture and releasing heat when you're warm, insulating when you're cool — so it suits hot, cold and variable sleepers alike. It's also naturally hypoallergenic and dust-mite resistant. See the Natural Home Australian Wool Duvet.
Mulberry silk is the coolest natural filling — it drapes close to the body, wicks moisture, and breathes, making it ideal for hot sleepers and warm months. Our Dreamtime Mulberry Silk Duvet is even machine washable. Browse all silk bedding.
A down-and-feather blend delivers natural warmth at a more accessible price. Feather adds weight and support while down adds loft. Our lightweight down feather blanket is a great layering option.
Which duvet filling is warmest? Goose down — especially a higher fill power like 850 — gives the most warmth for the least weight.
Which filling is best for hot sleepers? Mulberry silk is the coolest, with Australian wool a close second thanks to its temperature regulation.
Which filling is best for allergies? Wool is naturally hypoallergenic and dust-mite resistant; our goose down is also washed for purity to be hypoallergenic.
How long does each filling last? With a duvet cover and proper care, all of our natural fillings last 10–20 years.
