PREMIUM SILK DUVET

Silk Bedding 140x220: Perfect for Winter

If you’re looking for the perfect silk bedding of 140x220 cm for winter, the OPSUNDBAY Silk Winter Duvet Extra Long - 140 x 220 cm is an excellent choice. Crafted with the highest quality materials, this extra-long silk duvet provides warmth and comfort during the coldest months. Whether you’re new to silk bedding or familiar with its unique benefits, OPSUNDBAY’s silk sets offer unmatched comfort, style, and functionality.

Why Choose Silk Bedding?

Silk is renowned for its natural temperature-regulating properties. When it’s cold outside, silk bedding keeps you warm; when it’s warm, it helps you stay cool. Silk’s unique breathability and moisture-wicking abilities set it apart from materials like cotton, as it doesn’t retain moisture, leaving your skin dry and comfortable throughout the night.

With our silk bedding in 140x220 cm, you get a beautiful and luxurious product and a hypoallergenic set that’s gentle on your skin—a great choice for those with sensitive skin or allergies.

Benefits of an Extra Long Silk Duvet

Our Extra Long Silk Winter Duvet isn’t just designed for length but for warmth as well. It combines the finest 100% long-fibre mulberry silk with a dense filling for maximum comfort on cold nights. The 220 cm length provides ample room for those who want extra space to snuggle.

Here are some of the top reasons to choose silk bedding from OPSUNDBAY:

  • Temperature Regulation: Silk helps manage your body temperature, keeping you from overheating or feeling too cold.
  • Hypoallergenic and Antibacterial: Naturally resistant to dust mites and mould, silk is ideal for allergy sufferers.
  • Softness and Comfort: Silk’s smooth surface minimizes friction on your skin and hair, which may help reduce tangles and frizz.

Caring for Your Silk Bedding

Although silk bedding is often considered delicate, it’s easy to maintain with the proper care. Using a mild silk detergent, our 140x220 cm silk bedding is machine washable on a low-temperature cycle (30 degrees). To extend the lifespan of your silk duvet, allow it to air dry, as silk dries quickly and naturally.
