Not sure which duvet fits? We've design a quiz to help! 

Filled with double-cocoon mulberry silk, the top grade of silk, and handmade by four skilled artisans for each piece, this mulberry silk-filled duvet insert stands as a beacon of luxury. With the inherent characteristics of silk, the duvet insert is supremely soft, smooth, and excels in temperature regulation.


  • Fill: 100% Double Cocoon Long-Strand mulberry Silk, the highest grade of silk with the fluffiest and smoothest texture
  • Shell: GOTS certified Organic Cotton, featuring a natural white glow and a 300 thread count in a sateen weave
  • Differs from the Mulberry Silk-filled Duvet Insert with Luxe Cotton Shell only in the shell material. A Luxe Long-Staple Cotton Shell offers a softer and silkier texture, while an Organic Cotton Shell provides a crisper and more sustainable alternative
  • Tack stitch to enhance fill stability while preserving the duvet's smooth and fluffy texture
  • Three loops on each side of the insert for securing with a duvet cover
  • Handmade by skilled artisans with decades of experience, each fill is hand-stretched from silk cocoons and professionally layered to ensure a smooth and even distribution
  • Shell and fill both surpass the strictest Class I OEKO-TEX® Standard 100 certification, tested and proven free of harmful chemicals
  • Strongly recommended for use with a duvet cover
  • Sun-curing recommended for regular maintenance 
  • Professional dry clean
  • Spot clean if necessary

Aeptom Duvet Shop

A duvet is not just a source of comfort. It is an essential element in achieving quality sleep and addressing sleep challenges. This video explores the materials and designs behind Aeptom duvets and provides an in-depth comparison based on cooling effects, warmth, softness, and weight to help you make an informed decision. Sleep better with Aeptom!

Inside the Silk Standard

At Aeptom, raw material quality and transparency are not marketing points. They are how we take responsibility for what goes into every duvet. This brought us to Tongxiang, China, a city with over a thousand years of silk history. The favorable local climate allows silkworms to spin stronger, more even cocoons. Generations of artisans have refined silk cultivation and craft over centuries, and that knowledge was preserved and evolved alongside technology. When your foundation runs that deep, quality is already rooted in the material.

Inside the Making

Good silk is the foundation. Good technique brings it to life. While silk sourcing has evolved with technology, the making of our Mulberry Silk Filled Duvet is still a story of traditional craft. Every very layer hand-stretched, every web carefully built, every duvet inspected before it reaches you. In an industry full of myths, our goal is to stay truthful and transparent.

Customer Review

"The real thing is as divine as the product description on the website. Excellent workmanship and quality. I bought the light weight one, since it’s for Florida. Very happy I found Aeptom via google search."

Mulberry Silk Duvet Insert

Oh Boy! This insert is exactly what I’ve been looking for. I sleep hot and couldn’t find a comfortable cooling blanket until now. Combined with percale bed sheets and duvet cover, my search is finally over. Thank you!

This duvet is wonderful. I love the drape, the weight and the gentle warmth. It isn't a cloying, sweaty warmth, but cozy and so comfortable.

Make everyday luxurious

I LOVE my new duvet insert! I was ready to upgrade from a longtime comforter to a real duvet, and when doing research I saw most were filled with polyester. I wanted one filled with natural material and I’m so glad that I decided to invest in this silk duvet. It’s so soft and luxurious while also being the perfect temperature (I live in Chicago and bought in the summer. Looking forward to seeing how it does in winter). We spend so much time in our beds so it was important to me to create a space I loved. Definitely recommend!

Amazing product

I am thrilled with the silk duvet insert. The quality is well beyond my expectations. I have a competitor’s $3000 insert and Aeptom’s is just as nice. A bargain for quality like this is difficult to find,

Love love love!

I purchased the lightweight duvet as a replacement for one I ruined trying to clean after spilling my morning latte (DRY CLEAN ONLY). As a hot/sweaty sleeper, the silk filling is a lifesaver! I’m so much more comfortable than with down or other fibers again. And the price is right!

Soft and Fluffy

I was searching for a duvet insert that wasn't filled with down or polyester and I’m very happy I stumbled upon Aeptom. I’m in love with the quality and marshmallowy softness. The lightest weight ended up being perfect for warmth without overheating during the night.

Had high hopes and it’s even better than expected

I was a bit skeptical at the price and the return policy but boy is this a high quality product. I replaced a $250 comforter from another well known brand and the quality of the Aeptom comforter is a whole different tier. Couldn’t be happier.

Perfect duvet

I couldn’t love it anymore than I do. I bought King lightweight duvet and it’s perfect for 50 degree nights as well as 75. It’s not at all heavy but seems to lay perfectly no matter what position I am in.
I bought a bamboo duvet cover to protect and it feels better than luxury hotel bedding.

So Soft

I love it!! I am a hot sleeper, and the All Season is definitely still a little much for me while it's 80F out, so I've stored it away for now to use it once it's cooler in a few weeks. I will definitely be looking to purchase a Summer one next year in time for the hotter season.
