Who it fits

Key specs explained

Size: King (104"x92")

This dimension provides extra surface area compared to standard Queen bedding. The additional width ensures the comforter drapes evenly over larger mattresses without hanging too short. You benefit from full coverage that stays in place during movement. When shopping, verify your duvet cover matches these exact inches to avoid fit issues or exposed mattress edges.

Fill Weight: 150 GSM (2.1 lbs)

Grams per square meter indicates the density of the silk filling. At 150 GSM, this insert offers light insulation suitable for warmer seasons or climate-controlled rooms. It is significantly lighter than weighted blankets, which typically exceed 15 pounds. This low density allows for breathability while still providing a gentle, hugging sensation without overheating.

Fill Material: 100% long-strand mulberry silk

Long-strand silk fibers create a smooth, durable filling that resists clumping over time. This material naturally regulates temperature by wicking moisture away from your body. Unlike synthetic fills, it remains breathable and hypoallergenic. You get a soft, luxurious feel that conforms to your shape, making it ideal for sensitive skin or those who prefer natural fibers.

Cover Material: 100% premium cotton

The cotton shell provides a breathable barrier that enhances the comforter's natural temperature regulation. It feels soft against your skin and allows air circulation to prevent heat buildup. This material is easy to care for when paired with a duvet cover. It complements the silk filling by adding a layer of gentle structure and durability for nightly use.

Certifications: OEKO-TEX Standard 100 Class I

This certification verifies the fabric is free from harmful chemicals and safe for direct skin contact. Class I specifically targets products for infants and sensitive individuals, ensuring rigorous testing standards. You can trust the materials are non-toxic and eco-friendly. This standard provides peace of mind regarding health and safety, distinguishing it from uncertified synthetic alternatives.

Design and build details

The listing specifies a 100% cotton shell enclosing 100% long-strand mulberry silk. This construction creates a breathable barrier that keeps the delicate fill in place while allowing air to circulate. The fabric choice suggests a focus on temperature regulation, which aligns with its Spring/Fall warmth rating. You get a smooth surface that feels soft against the skin, while the cotton cover offers durability and ease of care when paired with a duvet cover.

Dimensions are listed as King (104"x92"). This width provides ample coverage for larger beds, ensuring the comforter drapes evenly without exposing the mattress edges. The total weight is approximately 6.7 pounds, with 2.1 pounds of silk fill. This distribution supports the mild warmth level intended for transitional seasons. The thickness is noted as 0.99 inches, indicating a flat, lightweight profile rather than a bulky puff.

Design features include eight anchor loops to secure the insert inside a duvet cover, preventing shifting during sleep. A side zipper allows you to inspect the silk authenticity, a practical detail for verifying quality. The listing notes OEKO-TEX Standard 100 Class I certification, confirming the materials are free from harmful chemicals. These elements combine to create a product designed for longevity and safe, comfortable use in moderate climates.

Setup and everyday use guide

You place this comforter inside a duvet cover to use it. The listing includes eight anchor loops designed to secure the insert. These loops attach to the cover’s interior ties. This setup prevents the silk fill from shifting during your sleep cycle. A side zipper is also present. You can use this opening to inspect the mulberry silk authenticity if needed. The product weighs about six pounds in total. This includes the 2.1 pounds of long-strand silk filling. The cotton shell adds the remaining weight. You should select a high-quality breathable duvet cover. This protects the cotton shell and preserves the soft feel. Daily care requires avoiding machine washing. The listing recommends dry cleaning or gently air drying in indirect sunlight. This maintenance approach helps the comforter last longer. The spring and fall warmth level suits mild summer weather with air conditioning. You will likely use this insert during transitional seasons. It may be too cool for deep winter months. The OEKO-TEX Standard 100 Class I certification ensures the materials are free from harmful chemicals. This makes the bedding safe for sensitive skin. You benefit from a hypoallergenic sleep environment. The precision tailoring suggests the stitching holds up well over time. You do not need to worry about the fill bunching up. The design keeps the silk evenly distributed. This setup process is straightforward. You simply insert the comforter and secure the loops. The zipper allows for easy access if you need to check the fill. This practical design supports long-term use.

Before You Buy This Silk Comforter

You need a duvet cover to use this insert. The listing does not include one. Choose a breathable cotton cover to match the comforter’s temperature regulation. Check that your cover has interior ties or loops. This product includes eight anchor loops for secure attachment. Verify your mattress size matches the King dimensions of 104 by 92 inches. Smaller sizes are available if needed. Care requires dry cleaning or gentle air drying. Avoid machine washing to protect the silk fill. This item fits the spring and fall warmth category. It is lighter than weighted blankets. It suits those who prefer natural fibers over synthetic fills. Compare its 150 GSM fill weight against other options.
