Which Sheep's Wool Duvet Is Suitable for People with Allergies?

Yes, a sheep's wool duvet can be suitable for people with allergies, provided that both the filling and the cover are carefully chosen. We recommend choosing a duvet with a pure virgin wool filling tested for harmful substances, a certified organic cotton cover and the ability to wash it at 30 °C on a wool cycle.

The reason lies in the sleeping climate: wool absorbs moisture produced by the body during sleep and then releases it back into the air. The filling therefore stays drier, while dust mites need the opposite, namely a warm and humid environment. Wool duvets are therefore considered hypoallergenic: wool fibres are naturally resistant to dust mites, mould and bacteria.

In brief

• Wool can absorb up to 30% of its weight in moisture without feeling wet.
• Dust mites dislike wool because of its breathability, which helps the filling stay drier.
• The cover is just as important as the filling. Certified organic cotton is particularly suitable when it is close to the skin.
• A wool duvet that can be washed at 30 °C on a wool cycle is easier to maintain.
• When choosing a natural duvet, it is preferable to avoid polyester and synthetic fibres.

Why does wool make the environment less favourable for dust mites?

Dust mites thrive particularly well in warm and humid environments. Wool, on the other hand, naturally absorbs moisture produced by the body during the night and gradually releases it back into the air.

Wool can absorb up to 30% of its weight in moisture without feeling damp. Thanks to its breathability, it helps maintain a drier and more comfortable sleeping climate.

This natural moisture regulation is one reason why wool is often considered particularly suitable for people who are sensitive to dust mites. The less humid the environment, the less favourable it is for dust mites.

The cover also plays an important role

The filling is not the only element to consider. The duvet cover is the layer surrounding the filling and is therefore the material closest to your skin.

Zizzz wool duvets use a certified organic cotton cover. The Swisswool filling is covered with a very fine cotton batiste that is soft and smooth to the touch and does not feel scratchy. The duvets are also designed without synthetic-fibre covers.

Five criteria for choosing a wool duvet suitable for allergy sufferers

Which Zizzz wool duvet should you choose?

Zizzz adult Swisswool duvets are available in different filling weights to suit different bedroom temperatures and sleeping preferences. The 4 Seasons model has a 290 g/m² filling, while the Winter model has a 460 g/m² filling. Both are filled with Swisswool and made in Switzerland.

Swisswool is made from 88% pure virgin Swiss sheep's wool and 12% plant fibres. The plant fibres reinforce the wool and make the filling machine washable. Wool naturally absorbs and releases moisture, helping to regulate body temperature during the night.

4 Seasons duvet, 290 g/m²

The 290 g/m² 4 Seasons duvet is suitable for most people and can be used throughout the year. It is a versatile choice for bedrooms with moderate temperatures.

If you tend to sweat during the night, however, a lighter duvet may be preferable in order to limit excess heat and humidity.

Winter duvet, 460 g/m²

The 460 g/m² Winter duvet is thicker and is better suited to cold bedrooms, less-heated rooms or people who tend to feel cold at night.

What about children?

The same principle applies to children's duvets: a breathable filling that naturally regulates moisture can help create a comfortable sleeping climate. Zizzz also offers a Swisswool children's duvet in 100x135 cm. It has a 290 g/m² filling, is suitable for year-round use and can be machine washed at 30 °C on a wool cycle.

Adult Zizzz wool duvets are made in Switzerland, in the canton of Schwyz.

To complete a natural sleeping environment, you can also discover our Swisswool wool pillows. Wool pillows are breathable, help regulate body temperature and are naturally resistant to dust mites, mould and mildew.

Care: what really matters for allergy sufferers

A wool duvet generally does not need to be washed very often. It is preferable to air it regularly, for example once a month, to refresh the filling naturally.

Avoid beating the duvet forcefully or vacuuming it. If washing is necessary, Swisswool duvets can be washed at 30 °C using a wool cycle and a suitable wool detergent. Avoid using a tumble dryer and do not dry the duvet directly in the sun.

For people with allergies, the duvet cover and bed linen also play an important role. They are directly in contact with the skin and can be washed more frequently than the duvet itself.

When is a wool duvet not the right choice?

A genuine wool allergy is different from a dust mite allergy. If you know that you react to wool itself, a wool duvet will obviously not be the right choice.

Some people who believe they are sensitive to wool may instead be reacting to substances used during processing. In this case, it may be worth choosing wool that has been tested for harmful substances and combined with an organic cotton cover.

A wool duvet is not a medical device and does not replace advice from a doctor or allergist. Its benefit is rather that it creates a breathable sleeping environment with good moisture regulation, which is less favourable to dust mites.

At Zizzz, our duvets can be tried for 30 nights with free delivery. If the duvet is not right for you, you can return it during this period.

FAQ: wool duvets and allergies

Is a sheep's wool duvet suitable for people with allergies?

Yes. Wool duvets are considered hypoallergenic because wool fibres are naturally resistant to dust mites, mould and bacteria. For people with allergies, it is preferable to choose wool tested for harmful substances and a certified organic cotton cover.

Why don't dust mites like wool?

Dust mites thrive in warm and humid environments. Wool can absorb up to 30% of its weight in moisture and gradually release it back into the air. Thanks to its breathability, wool stays drier and creates an environment that is less favourable to dust mites.

Wool or down for a dust mite allergy?

Wool naturally regulates moisture and helps keep the filling drier. Down and feathers can retain dust and particles. For someone sensitive to dust mites, wool is therefore often an interesting choice.

Can you wash a wool duvet?

Yes. A Swisswool wool duvet can be machine washed at 30 °C using a wool cycle and a suitable wool detergent. Avoid using a tumble dryer and do not dry the duvet directly in the sun.

What filling weight should allergy sufferers choose?

A filling weight suited to the bedroom temperature is preferable. The 290 g/m² 4 Seasons model is suitable for most people and can be used throughout the year. The 460 g/m² Winter model is intended for cold bedrooms or people who tend to feel cold. A duvet that is too warm can increase sweating and humidity.

Does a sheep's wool duvet feel scratchy?

No. Swisswool is covered with very fine cotton batiste that is soft and smooth to the touch. The duvet therefore has a soft outer layer that prevents direct contact with the wool fibres.

What is Swisswool made of?

Swisswool is made from 88% pure virgin Swiss sheep's wool and 12% plant fibres. This combination creates a natural, breathable filling that can be machine washed on a wool cycle.
