Frequently asked questions
What momme weight should I look for in a mulberry silk duvet?
Momme weight indicates silk density; 19-22 momme is standard for year-round use, while 25+ momme is heavier and more durable. Lower momme (under 19) is lighter but less durable.
How do I clean a mulberry silk duvet?
Most high-end silk duvets require dry cleaning to maintain fill integrity. Some budget-friendly options are machine washable on gentle cycle with cold water and mild detergent. Always check the care label.
Are mulberry silk duvets hypoallergenic?
Yes, 100% mulberry silk is naturally hypoallergenic and resistant to dust mites, mold, and mildew. Many duvets also have OEKO-TEX certification, ensuring no harmful chemicals.
Can I use a silk duvet without a cover?
It's recommended to use a duvet cover to protect the silk fill and extend its lifespan. Silk duvets are often machine washable only with a cover, and the cover itself may need special care.
What is the difference between silk duvet and silk-filled comforter?
Both are often used interchangeably, but a duvet typically refers to a removable cover, while a comforter is a standalone bed covering. In practice, silk duvets are inserts that require a cover, while some silk comforters have a sewn-in cover.
