How do I choose the right Down Duvet Insert weight?

The Down Duvet Insert is available in three weight options: Lightweight — ideal if you run warm or live in a mild climate. Midweight — balanced for most climates and seasons. Ultra-weight — the coziest and warmest option for cold climates or chillier sleepers. Choose the weight based on your preferred temperature. And, remember, with our 30-Night Guarantee, you can trial your selection.

Why is the Down Duvet Insert larger than the Duvet Cover?

The insert is intentionally sized just a bit larger so that it fills out the cover and gives a plush, fluffy look. This sizing helps the duvet drape nicely and avoids a flat, undersized look.

What’s the difference between Down and Down Alternative?

Our triple-washed mix of down and feathers provides a classic, lofty, plush feel with superior warmth-to-weight ratio. Down Alternative offers a hypoallergenic option: it’s typically lighter, easier to care for, and better suited for sleepers with allergies.

What is the Down Duvet Insert shell made of?

The outer shell is crafted from the highest-quality, 100% organic cotton with a percale weave that is naturally down-proof, resisting poke through of features, while still allowing breathability and comfort.

Is the down used in the insert sustainable?

Yes. The down is sourced from U.S. farms and is IDS-certified, meaning the down and feathers are inspected to ensure compliance with ethical standards (no live-plucking or force-feeding).

How do I care for the Down Duvet Insert?

The Down Duvet Insert is machine-washable. Use a gentle, cold wash cycle and a mild detergent. Tumble-dry on low heat until completely dry (you may need more than one drying cycle to restore loft). To speed up the drying process, add a few wool dryer balls.

Will the down stay evenly distributed over time?

Yes. Thanks to our unique baffle-box construction design, the down remains evenly distributed inside the insert, even after extended use or movement.

How often to wash:
You don’t need to wash your duvets often — we recommend once every season. Washing your duvet cover regularly will ensure the insert stays cleaner and will prolong its lifespan.

To speed up drying:
Our duvet inserts are delightfully large and have incredible loft, which means they’ll take a few dryer cycles to dry completely. Toss a few wool dryer balls in the dryer to help speed things up and keep them feeling fluffy.
