Questions About Our Duvets

What is the difference between wool, down and synthetics?

Down and synthetics are primarily insulators - they keep the body hot and don't release heat. During the night, these insulators raise our body temperature, which makes us feel hot. So, we either wake up fully or toss and turn to cool off. If you ever woke up feeling sweaty, this is likely why.

Wool is not just an insulator; it also acts as a temperature regulator. Wool naturally absorbs and releases moisture to either cool or warm your body. You get warm quickly when you sleep in wool, but thanks to the fabric’s exceptional breathability, you do not overheat.

What are the advantages of a Zizzz duvet with Swisswool?

Our Duvets with Swisswool are light and airy. They provide a very comfortable sleeping climate all year round. The unique temperature regulating qualities of wool will help you to wake up fresh every morning.

Wool is a naturally hypoallergenic, highly- breathable and it doesn't attract dust. Down and feather tend to attract dust and dirt, as well as dust mites. Dust mites do not like wool because of the way wool breathes. The wool in the duvet stays drier than other fillings. The lower the humidity, the less comfortable the environment for dust mites.

Our duvet is also machine-washable.

Is a duvet with Swisswool itchy?

No, the Swisswool itself is not itchy. On top of that our Swisswool is covered with a very fine, fair-trade cotton batiste. It has a very soft and smooth feel

Can I wash my Zizzz Swisswool duvet?

Yes, you can wash a Zizzz Swisswool duvet in your washing machine with absolutely no problem. Just be sure to use the wool program and a wool detergent.

The only thing you should not do is using a dryer. Wool doesn’t like that.

How do I care for my Swisswool down to last longer?

Airing and shaking your down regularly will keep it in good condition. As we sweat during our sleep, this simple gesture will allow you to eliminate the moisture accumulated during the night. Your bed will not become a space for various bacteria. It will also help the feathers to keep their shape longer.

Do you have different weights?

We offer 2 different weights for our woolen duvets. Most of our duvets are stuffed with wool at the rate of 290 grams per square meter. This is the average weight for a down and is ideal all year round for the majority of people who live in a house with central heating. It is only on hot summer days when you sleep with nothing on you that down is useless.

We also offer 2 duvets padded of 460g / m2 in sizes 160x210cm and 200x210cm, which is ideal for cold interiors as well as cold winter periods, or simply for very chilly people.

Do you have different sizes?

For adults, we currently have eight sizes and two different weights:

For children, we have two available sizes:

What size of down should I choose to fit my bed?

In addition to the size of the bed, there are two other factors to consider. First, the desired fallout on each side of the bed and secondly the size and the movements of the sleepers.

We recommend you,

-a 140x200 cm down for a single bed of 80x200 cm, 90x200 cm, and 140x200 cm,

-a larger down 160x210 cm (Swiss standard size) for a single bed of 80x200 cm, 90x200 cm, and 140x200 cm for more comfort,

-a down of 200x210 cm for a double bed of 120x190-200 cm, if you want to avoid a big fall on the sides of your bed,

-two 160x210 cm duvets for a 120x190-200 cm double bed, if your partner pulls the duvet down on his side during the night and you want to have your own down,

-a down of 240x240 cm for a double bed of 140x190-200cm, if you want your down to leave you a large extent.

What is the difference between a duck down and a goose down?

Downs stuffed with goose feathers are more expensive because they are taken from mature geese and therefore required a longer breeding time. Thus, the goose feathers have higher warming properties than those of duck. At an equivalent weight, the goose down will be warmer than duck down, but it will also be lighter.

The origin of the feathers is a crucial criteria because food and environment will determine the quality of the down. The better the quality, the greater the interconnection between the feathers. This will ensure optimal thermal quality.

So, in the end, the most important thing does not lie in the differences between the goose or duck feathers but in the choice of a high quality down like we produce.
