Frequently asked questions
What makes a duvet feel 'soft as down'?
Softness comes from fluffy materials like microfiber, down, or a down-alternative blend with high fill power. Baffle-box construction helps maintain loft and prevents fill from shifting.
Is down alternative as soft as real down?
Premium down alternatives, especially microfiber or TENCEL-filled ones, can feel very similar. Many owners report they can't tell the difference, and down alternatives are hypoallergenic and more affordable.
What certifications should I look for in a soft duvet?
Look for OEKO-TEX Standard 100 (no harmful chemicals), GOTS (organic cotton), or Downpass/RDS (ethical down). These ensure softness and quality without toxins.
How do I keep my duvet fluffy?
Fluff it daily, use a duvet cover, and wash every few months with a down-safe detergent. Dry with tennis balls to restore loft.
What is the best fill for a soft duvet?
Ethically sourced goose down with 700+ fill power or a high-quality down alternative like microfiber or TENCEL blend. Both offer cloud-like softness.
