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 most premium grade of silk
  • Shell: Luxe Long-Staple Cotton with a 330 thread count and a sateen weave. Buttery smooth and extra soft  
  • Differs from the Mulberry Silk-filled Duvet Insert with Organic 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 daily 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.

Optimal comfort

Through the years I have tried many different kinds of comforters especially for the summer months and the mulberry silk insert from Aeptom is the top choice as it truly regulates temperature and I am able to sleep soundly for 6 or 7 hours without waking up during the night. The insert feels luxurious and the quality is top notch. Compared cost to other brands and this was a winner all around. I feel refreshed and fully rested each morning!

Sleeping like a baby!

I have tried many sheets, bamboo linen percale and cotton. I always stayed away from silk as in my mind. It would be too slippery if you will. However, I was terribly wrong.. These are the most comfortable sheets I have ever laid on. They kept me cool at night and yet warm at the same time (I sleep with AC on 64).

Perfect Luxury Comfort – Worth Every Penny

I couldn’t be happier with this duvet insert. From the first night, I noticed how incredibly soft, light, and comfortable it is. It has the perfect balance of warmth without feeling heavy or making me overheat. The mulberry silk filling feels luxurious, and the cotton shell is smooth, breathable, and high quality.

The craftsmanship is outstanding, and it gives my bed a true hotel-quality feel. It stays fluffy, drapes beautifully, and has made a noticeable difference in my sleep quality. Every night feels more relaxing and comfortable.

I spent a lot of time looking for the right duvet, and I’m so glad I chose this one. It exceeded my expectations in every way. I highly recommend it to anyone looking for premium quality and exceptional comfort. Definitely a five-star product!

Finally found the perfect duvet insert

Could not be happier with my purchase. The promises made were kept. The insert is beautifully crafted and feels amazing. I purchased the light weight as I am a very hot sleeper but it still gives me the weight I like in a duvet. Highly recommend.

Quite nice!

This is a lovely comforter.. As well, the diver cover. I kind of like it with the crease marks still in it. I slide a little bit when sitting on the edge.. have a knee replacement so movement of the foot on that leg when putting on socks is a bit tricky. What temperature to iron on after a washing?

Great products, even better service

Incredibly Happy!!

I had never heard of this brand or Millbury silk duvet insert, so is taking a chance here. I’ve used down alternative because I tend to sleep hot and wind up sweating. I’ve been using it now for two weeks and have had the best nights sleep I’ve had in a while. It feels so luxurious you and I love how it doesn’t clump. Very impressed with the quality and how beautifully it came packaged.

Best ever

I honestly think Aeptom makes the best silk duvets. I bought the organic cotton one a few years ago and absolutely loved it. This year, I wanted something a little lighter but wasn’t sure which shell option to choose (they didn't have these options before). Customer support was amazing. They explained the differences clearly and didn’t try to push me into anything, which I really appreciated. I ended up going with the luxe cotton version in lightweight, and it’s even better than I expected. It’s so soft and fluffy, and I think I like it even more than the organic cotton one. Will definitely be ordering more!
