01 Details +
The Sensoire mulberry silk duvet is handmade with 100% Grade 6A double-cocoon, long-strand mulberry silk and finished with neat box quilting. Light and breathable, it keeps you cool in summer and cosy in winter without the weight of down. With proper care, it can last for 15 to 20 years.
The Silk Fill
100% Grade 6A double-cocoon mulberry silk, spun by two silkworms together so it is plumper and more resilient than single-cocoon silk. Hand-drawn into long strands and layered by hand, then box-quilted in even squares so it holds its loft and never clumps or shifts into cold spots. Breathable, temperature-regulating, hypoallergenic and dust-mite free.
The Cotton Shell
The silk is held in an 80s (80-count) pure cotton sateen shell at 400 thread count, white with white piping, in a classic 4-over-1 weave with an elegant drape and soft sheen. Use a duvet cover to protect the silk and keep it fresh. Eight or more ties help secure the duvet inside its cover.

03 Duvet care +
The silk contains Sericin, a natural protein that resists allergens and discourages microbial growth. Water and high heat break these protections down and make the silk clump, so the duvet itself is never washed. Always sleep with a duvet cover over it and wash only the cover.
- Always use a duvet cover and wash the cover, not the duvet
- Never machine wash, soak or tumble dry the silk duvet
- Air the duvet in gentle sunlight 1 to 2 times a year
- Do not bleach or wring the silk
- Spot clean small marks with cold water, do not soak
- Keep the silk away from high heat
- Air the duvet outdoors to refresh its loft
- For a deep clean, use a specialist silk dry cleaner
Grade 6A Fill
Double-Cocoon Silk
Loft that holds, season after season.
Double-cocoon mulberry silk forms when two silkworms spin one cocoon together. Its naturally intertwined filaments are thicker and more resilient than single-cocoon silk, helping the fill stay plump and recover its shape over time. More body, lasting loft and consistent warmth.
Up to 1,200 Metres
Long-Strand Mulberry Silk
One unbroken thread, never a cold gap.
Mulberry silk filaments can reach up to 1,200 metres. Our long-strand silk is drawn by hand into continuous sheets, forming a soft, breathable web that stays evenly arranged instead of separating or clumping. The result is light warmth that moulds gently to the body and stays in place.
80-Count Pure Cotton
Pure Cotton Sateen Shell
A shell as quiet as the silk inside.
The casing is woven from 80s long-staple cotton at 400 thread count, with a smooth sateen finish. Breathable and cool against the skin, it has a soft, fluid drape and stays quiet as you move. The pure cotton feel is finished with clean white piping along the edge.
Square Box Quilting
Square Quilting
Every box holds the silk in place.
A neat grid of square quilting finishes the duvet, with each line guided by hand at the sewing machine. Every square holds the silk evenly in place, giving the duvet a clean, tailored finish and consistent warmth from corner to corner.
Lasts 15 to 20 Years
Made by Hand
Hand-pulled, hand-layered, made to last.
Each layer of silk floss is stretched and cross-laid by hand so the fill keeps an even loft and does not shift into cold spots. The silk is laid by hand, and every quilting line is guided by hand at the machine. With proper care, a Sensoire silk duvet can last for 15 to 20 years.
Dust-Mite & Allergy Resistant
Clean by Nature
Pure protection, gentle on skin.
Mulberry silk protects you while you sleep. Its natural Sericin protein resists dust mites, mould and microbes, so the fill stays fresh and hygienic year after year. Naturally hypoallergenic and gentle on reactive skin, silk also carries almost no static, so nothing clings and nothing irritates. Cleanliness woven in by nature, not added by chemicals.
From the Journal
How a Sensoire Silk Duvet Is Made
A silk duvet looks quiet and simple: a pale shell, a soft outline, a light layer resting over the body. What shapes its feel, its even loft and the way it holds together lies inside.
Eight steps, from hand-stretched long-strand mulberry silk to cross-layering, shell selection and final inspection.
Read the journal →What The Fibre Does
A Fibre That Releases Heat
Where The Moisture Goes
Your body gives off heat and moisture all night. Dense synthetics hold both against the skin, and that trapped damp is what wakes you feeling muggy.
Silk works the other way. Its pores draw moisture in, around 30% of the fibre's own weight, then release it through those same openings. The surface returns to feeling dry instead of holding the damp against your skin.

Before You Buy
Silk Duvet, Answered
What is double-cocoon (doupion) mulberry silk?
Double-cocoon, or doupion, silk forms when two silkworms spin a single cocoon together. The filaments intertwine into a thicker, more resilient floss than ordinary single-cocoon silk, giving the fill more loft, more spring and a longer life. It is a premium grade of mulberry silk fill.
What is the difference between long-strand and short-strand silk fill?
Short-strand fill is made from shorter lengths of silk floss, which can shift, clump and leave thinner, cooler areas over time. Mulberry silk filaments can reach up to 1,200 metres; this describes the filament length, not the size of a finished sheet of filling. Our long-strand silk is drawn into continuous sheets and layered by hand to form an even, breathable web that stays in place.
What is the shell made of, and can I add a duvet cover?
The shell is 80s pure cotton sateen at 400 thread count, breathable, soft and quiet, finished with white piping, with a short concealed opening so you can inspect the silk inside. We recommend always using a washable duvet cover, fastened at the corners, so the silk stays in place and rarely needs cleaning.
Will the silk shift or bunch inside the duvet?
No. This duvet is finished with square box quilting, a neat grid of stitched compartments that hold the silk in place. Each box keeps the fill evenly spread, so it will not migrate to one side or leave thin cold spots, for consistent warmth from corner to corner.
Is this duvet really handmade, and where is it made?
Yes, entirely by hand, in Suzhou, China, the historic home of mulberry silk, where the fibre has been reeled and woven for centuries. This duvet is made by a long-standing partner to our specification: whole double cocoons are sorted by hand, boiled in spring water with plant ash rather than chemical degumming agents, opened by hand into silk caps, dried in soft daylight, then stretched by four artisans into layer after layer of continuous silk and held inside the 80s cotton sateen shell with square box quilting, every line guided by hand at the machine. No machine-shredded floss, no bleaching. Each finished duvet is checked before it leaves, and any fault in the making is covered by our 14-day returns.
Does box quilting work against long-strand silk?
No, the two do different jobs. The long strands are what stop the fill breaking down into clumps and thin spots. The quilting is what stops the whole sheet sliding around inside the shell. On short-fibre duvets the boxes carry all of that load, so they have to be small and tightly sewn. Here the silk already holds together as one continuous web, and the square quilting simply anchors it, which is why the boxes stay generous and the loft stays even across them.
Is a silk duvet good for hot sleepers?
Yes. Silk is naturally breathable and temperature-regulating; it wicks moisture and releases heat instead of trapping it, so you sleep warm without overheating. The lightweight summer weight (180 g/m²) suits hot sleepers and warmer bedrooms especially well.
Is silk hypoallergenic and safe for allergies or asthma?
Yes. Mulberry silk is naturally hypoallergenic and resists dust mites, mould and mildew. It also contains sericin, a natural protein associated with fewer allergic reactions. Our fill is certified to OEKO-TEX Standard 100, tested free from harmful substances, so it is gentle on sensitive skin.
How warm is it, and which weight should I choose?
Sensoire comes in three weights plus a four-season set. The summer weight (180 g/m²) is light and cool for warm nights; the mid-season weight (320 g/m²) carries you through spring, autumn and milder winters; the winter weight (500 g/m²) is made for cold bedrooms. The four-season set pairs the 180 and 320 duvets, which tie together into a 500 g/m² winter layer. Choose by the temperature of your bedroom rather than the season alone. Sizes run from 140x200 cm to 260x240 cm.
What tog do these weights correspond to?
Silk is measured by fill density in g/m², also written gsm, rather than by tog. As a close equivalent, Summer 180 g/m² is about 2.5 to 4.5 tog, Mid-season 320 g/m² about 6 to 9 tog, Winter 500 g/m² about 10 to 13 tog, and the Four-season pair tied together about 12 to 13.5 tog. Treat those figures as a guide for comparison, not a specification. Tog measures insulation on its own and says nothing about how a fibre handles moisture, which is why two duvets rated at the same tog can feel very different by morning.
Can two of us sleep under different weights in the same bed?
Yes, and it is usually the simplest answer when one of you runs warm and the other runs cold. Put two single duvets on one bed, each in its own weight, for example Summer 180 g/m² for the warm sleeper and Mid-season 320 g/m² for the cooler one. It is the ordinary arrangement across Scandinavia. A shared bedspread laid over the top keeps the bed looking whole by day.
I am switching from a down duvet. What changes?
Three things, mostly. There are no quills, so nothing works its way through the shell and pricks you in the night. The fill does not drift, so you will not wake to everything gathered at one end and a cold gap at the other. And silk sits closer: the same warmth arrives as a thinner layer that follows your shoulders rather than doming above them. What does not change is the cover. Dress it as you would any duvet, and wash the cover rather than the duvet.
Can I wash a silk duvet in the machine?
No. Never machine wash or tumble dry the silk fill, as water and agitation mat the fibres, degrade the silk and shorten its life. Protect it with a washable duvet cover and wash only the cover. The silk itself needs only airing and the occasional spot clean.
How do I care for and freshen my silk duvet?
Air the duvet outdoors in gentle sunlight for about an hour on each side, once or twice a year, to refresh the fill's loft. Spot-clean small marks with a little cold water, without soaking the silk. For a deeper clean, use a dry cleaner experienced in caring for silk duvets. Protected by a washable duvet cover, the duvet itself rarely needs cleaning.
My new duvet has a faint smell. Is that normal?
Yes, and it is harmless. A faint natural scent comes from sericin, the silk's own protein, not from any chemical treatment. Air the duvet for a few days and it fades, usually within a couple of weeks.
Does it have corner ties, and which duvet cover size do I need?
Yes. There are ties at each corner and eight or more around the duvet in total, so it stays put inside your cover instead of sliding down through the night. For the cover, match the duvet size or go a centimetre or two larger. A much larger cover lets the duvet travel; a smaller one flattens the loft at the edges. Sizes run 135 x 200, 140 x 200, 155 x 220, 160 x 210, 200 x 200, 200 x 220, 240 x 220 and 260 x 240 cm, so most standard covers have a direct match.
Which duvet cover should I use, and does the cover change how cool it sleeps?
It changes it more than most people expect. Heat and moisture leaving the duvet have to pass through the cover, so a cover that breathes lets the silk do its work, and one that does not can leave you in a pocket of heat under the very same duvet. Choose a breathable cover in a natural or plant-based fibre: linen, silk, our bamboo lyocell, cotton percale or cotton sateen. Avoid polyester, microfibre and polycotton, which hold heat and damp against you. If a duvet that felt cool on its own suddenly feels warm, look at the cover first. A cover also keeps the silk clean and the duvet in place, held by ties at each corner and eight or more around the edge.
How do I store the duvet out of season?
Air it first, then store it dry. Give it an hour each side in gentle sunlight, let it cool, and fold it loosely into the satin storage bag it arrived in, which keeps dust off without sealing the silk in. Keep it in a dry cupboard away from heat, damp and direct light. It can be pressed down a little to save space, by up to about 40% of its full loft, but never vacuum-packed flat: long-strand silk holds its loft because the layers are stretched open, and months of full compression flatten them. When the season turns, shake it out and hang it for an afternoon and the loft returns. The 4 Seasons pair makes this simple, since one layer is always in use and only the other is stored.

This product cannot be washed, but the quality is excellent. A duvet cover is essential. When I first received it, I had to let it air out for a while….

I was a little skeptical at first since this was my first time buying a silk duvet, but it turned out to be much better than I expected. The design is simple but still looks elegant and high-end. The fabric feels amazing. It’s really soft, comfortable, and breathable. Best of all, I don’t feel hot under it at night. Really happy with this purchase so far!

Really like this product. Very light & soft and not too warm. Great for Spring and Fall
Kinga K. –
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!

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.
Auz Amélie –
The quality of this silk duvet is truly outstanding. The more I sleep with it, the more comfortable it feels, soft, lightweight, and perfectly gentle against the skin. It gives such a cozy and luxurious sleep experience. The seller is also wonderful to work with, always responsive and helpful whether it’s about customization or general questions. Highly recommended!
