Questions about our down duvets

Mann und Kind unter einem Zizzz Duvet


What is a down duvet? How are down duvets different from synthetic or wool duvets?

A down duvet is a type of duvet filled with the soft, fluffy clusters taken from the underside of geese or ducks. Down is known for its lightness, warmth, and fluffiness. Synthetic duvets, on the other hand, are made from man-made, artificial materials, while wool duvets are made from natural wool fibers, usually those of sheep, lamas, camels or alpacas.

What are the benefits of using a down duvet?

The benefits of down duvets include their natural insulating properties, lightness, and fluffiness. If properly cared for, down duvets can also last for many years.

Down duvets are warmer, softer and lighter than synthetic or wool duvets. Unlike feathers, down is voluminous in shape and does not have a hard stem or quill. Down is found on the belly area of geese and ducks, beneath the feathers, and serves to keep the animals warm in winter and cool in summer. The structure of a down cluster is similar to that of a snowflake. The individual down clusters are negatively charged and arranged in a radial pattern, which means they are always spaced apart. The insulating power is generated by the air cushions between the individual down flakes. These air cushions provide the space in which down can trap moisture and transport it away to the outside, away from your body.

Whom are down duvets best suited for?

Down duvets are best suited for individuals who are looking for a lightweight and fluffy duvet which provides exceptional warmth and insulation. Down is a natural and luxurious material that provides a high level of loft, which means that down duvets can offer excellent warmth without feeling heavy or bulky. Down duvets are also known for their ability to fit the sleeper's body.

Down duvets may not be the best option for people who tend to sleep hot, as they can trap heat and cause the sleeper to overheat.

Where does high-quality down come from?

High-quality down typically comes from the underbelly of geese or ducks, where the down clusters are the largest and the most insulating. The best down is usually sourced from mature birds, which naturally have larger and more mature down clusters.

The country of origin can also be an important factor in determining the quality of the down. For example, down from countries with colder climates, such as Canada, Iceland, and Eastern Europe, is generally considered to be of higher quality, as the birds are exposed to harsher conditions. This leads the animals to grow denser and more insulating down clusters.

Finally, down's quality also depends on the processing methods used, such as how the down is washed and sterilized. The standards set by industry certifications, such as DownPass or the Responsible Down Standard (RDS), also play an important role. These certifications ensure that the down is ethically and sustainably sourced, and that the birds are treated humanely throughout the entire supply chain.

Our goose and duck down is sourced from Eastern Europe. All of our down duvets and pillows are DownPass certified.

How warm are down duvets? Can they be used all throughout the year?

Down duvets are known for being excellent insulators, which make them suitable for all seasons. Down duvets are warmer than wool duvets. How warm a down duvet is depends on its fill power and weight. Higher fill power and weight indicate a warmer duvet.

Are down duvets hypoallergenic?

Down duvets are not inherently hypoallergenic, as some people may be allergic to the proteins in the down feathers. However, high-quality down duvets are often treated to remove allergens and dust particles.

At Zizzz, our down duvets are NoMite certified. The cotton case our duvet comes in is woven so densely that it is difficult for mites to enter it, making it great for asthma and dust allergy sufferers.

How do I keep my down duvet in good condition?

To care for your down duvet, you should fluff it daily to keep its loft and prevent any clumps from forming. Down duvets should be washed and dried in commercial-size machines or professionally dry cleaned. Avoid using fabric softeners or bleach, as these can damage the down clusters.

Can down duvets be used with a duvet cover?

Yes, you should absolutely use a duvet cover with your down duvet to protect it from dirt, stains and general wear and tear.

At Zizzz, we offer breathable duvet covers made from certified organic cotton. 

Are down duvets more expensive than other types of duvets?

Down duvets can be more expensive than synthetic duvets, but the price depends on factors like the down's quality, the manufacturing process and country of manufacture. 

At Zizzz, we keep our prices down by selling our products online and thereby eliminating middlemen and wholesalers, thereby keeping a Swiss or German-made down duvet affordable for our customers. 

What is the difference between fill power and fill weight in a down duvet?

Fill power refers to the loftiness and insulating properties of the down clusters, while fill weight refers to the total weight of the down used in the duvet. As stated above, higher fill power and weight indicate that the duvet is warmer and more luxurious.

Do you have different weights?

The weight of our down duvets depends on the product's size. For example, the filling of our duck down duvet in the size 160x210 weighs 600 g.

Do down duvets have a smell? If so, how do I get rid of it?

Some down duvets may have a slight odor due to the natural oils in the down feathers. To get rid of the smell, air out the duvet for a few days or use a natural odor absorber like baking soda.

What size duvet should I choose to fit my bed?

In addition to the size of the bed, there are two other factors to consider. First, how much of the duvet you want to fall out on each side of the bed and secondly how much you or you and your partner move around at night.

We recommend the following:

  • for a single bed of 80x200 cm, 90x200 cm, and 140x200 cm, we recommend a 140x200 cm duvet
  • for more comfort in a single bed of 80x200 cm, 90x200 cm, and 140x200 cm, we recommend a larger duvet, as in160x210 cm (Swiss standard size)
  • if you don't want your duvet to hang on the floor next to your bed, a duvet of 200x210 cm for a double bed of 120x190-200 cm
  • two 160x210 cm duvets for a 120x190 cm or 120x200 cm double bed, if your partner pulls the duvet down on his side during the night and you want to have your own duvet
  • a 240x240 cm size duvet for a double bed of 140x190 or 140x200cm, if you want your duvet to cover or even envelop you under all circumstances
