Imagine falling asleep under a pure silk duvet. A pure silk duvet is naturally hypoallergenic, moulds to the contours of your body and regulates your heat through it's unique layering of silk floss.
LEARN MOREA silk-filled duvet offers a luxurious sleep experience thanks to its breathable, hypoallergenic, and temperature-regulating properties. But the outer casing—either cotton or silk—can significantly affect how the duvet feels and performs. Here's how they compare:
1. Breathability & Temperature Regulation Both silk and high-quality cotton are breathable, but silk has the edge in natural temperature regulation. A silk case enhances the duvet's ability to wick away moisture and maintain an even temperature, ideal for hot sleepers or those in warmer climates. A cotton case, is also breathable but more absorbent, making it require more frequent cleaning.
2. Feel & Comfort A silk casing delivers unmatched lightness, softness and a smooth, almost frictionless touch against the skin—perfect for those who enjoy a luxurious, cool-to-the-touch sleep surface. Cotton, while soft in premium weaves like sateen or percale, has a different texture—more matte and slightly crisper. If you prefer a more natural, slightly firmer feel, a cotton case may be your choice but it won't drape over your body as well and could cause cold air gaps.
3. Durability & Maintenance Cotton is generally easier to care for. A cotton-covered silk duvet is more durable, while a silk-cased duvet typically requires more delicate handling—usually dry cleaning or spot cleaning only. For busy households, cotton offers more convenience.
4. Allergen Resistance Silk is naturally hypoallergenic and resistant to dust mites, mould, and mildew. A silk casing enhances these benefits throughout the entire duvet. However, a cotton cover still maintains most of the hypoallergenic advantages due to the silk filling.
5. Aesthetic & Luxury Appeal Silk undeniably looks and feels more luxurious and is significantly lighter. A silk-cased duvet brings elegance to any bedroom with its natural sheen and drape.
Which Should You Choose? If you're seeking the ultimate in luxury, softness, and thermoregulation, a silk-filled duvet with a silk case is ideal. For those who prioritise ease of care, durability, and a more classic touch, a cotton case is a practical and still highly comfortable choice. Both offer excellent benefits—your lifestyle and preferences will guide the best fit for you.
We use only the finest layers of Mulberry silk in a Silkweb duvet. A standard autumn weight duvet consists of more than 200 silk layers. Each layer is carefully stretched and placed by hand to provide easier airflow. Silk also has a natural ability to help regulate temperature. Because of this body heat is retained during the winter and released during the warmer months.
Manufactured in China, our silk duvets are made in a factory that has been awarded the OEKO-TEX Standard 100 certification. This ensures that our duvets are made from natural products that do not contain any harmful chemicals or substances.
The best quality silk is cultivated Mulberry silk. When silk worms are fed on mulberry leaves they produce the best quality silk which is naturally pure white, round, strong, smooth and produces long fibres necessary for the best silk duvets. Tussah silk is wild silk that has not been fed on mulberry leafs and is naturally brown and coarse. Because, it is brown, manufacturers tend to bleach the silk to try and make it look nice, hence a strong smell and the fibres will not be long.
Choose from either a silk cased duvet which has is fully hypoallergenic, drapes beautiful over your body and is really lightweight or a cotton cased duvet which is more durable and cheaper but still uses the same silk floss filling.
We offer 3 weights of duvet, a summer weight which is ideal for those warm summer evenings, an autumn weight which is our most popular and for most people is the year round answer but also a winter weight which is a summer weight and an autumn weight duvet which can be combined together.
Our summer weight duvets are 2-4.5tog and our autumn weight duvets are 6-9 tog.
Getting the correct weight for a duvet is very subjective and changes from person to person, but a silk duvet really helps in getting the correct temperature for your sleep as the layers of silk help to regulate the airflow and heat to your body.
Yes, if you wish to be really toasty in the winter you can combine a summer weight duvet with an autumn weight duvet so that you get a combination winter weight duvet. This will be equivalent to an 11 tog duvet. To combine, you simply use the button and loop system on the duvets to button the duvets together. Buttons and loops are located around the edge of the duvet at each corner and midway between each button on the sides and top and bottom.
A premium hand-made silk duvet is made by layering silk across a frame in a criss-cross pattern and then attaching to the case with threads. The best way to clean a silk duvet is to let it air in the sun for a coupe of hours. As silk will wick away moisture from a duvet and hence keep it dry and free from mites, it needs an occasional natural airing. We also recognise that a duvet can get stained. That is one reason why we chose silk as a case as it inhibits more stain resistance than cotton which naturally absorbs the stain and will then look dirty, whereas silk cases will stay cleaner for longer and maintain their beautiful sheen. If you do need to clean our duvets we do NOT recommend washing but rather localised cleaning with warm soapy water which should remove most marks.
