Frequently asked questions

What size duvet is 108 x 98 inches?

A 108 x 98 duvet is typically a California King size, but it may also fit an oversized king or specific custom beds. Always check your bed dimensions and duvet cover size.

What fill power should I look for in a duvet?

Fill power indicates the loft and insulating ability of down. For a duvet, 600-700 fill power is good for moderate warmth, while 700+ provides more warmth without weight.

Are down alternative duvets better than down?

Down alternative duvets are synthetic, hypoallergenic, and easier to wash, but may not last as long as down. Down offers better breathability and longevity but requires professional cleaning.

How do I care for a duvet?

Most duvets are machine washable on a gentle cycle, but some down duvets require dry cleaning. Use a duvet cover to protect it and wash the cover regularly.

What is OEKO-TEX certification?

OEKO-TEX Standard 100 certifies that textiles are tested for harmful substances, ensuring the duvet is safe for sensitive skin and free from chemicals.

The verdict

For most people, the Brooklyn Bedding Down Duvet offers the best all-around balance of warmth, quality, and durability. If you sleep hot, the Buffy Breeze Duvet is an excellent cooling alternative. Budget-conscious shoppers should consider the Casper Down Duvet for its reliable construction at a slightly lower price.
