The inner workings of a down duvet explained.

Goose down can be found on the chest and stomach of the goose. The down is hidden underneath a layer of feathers that acts as a waterproof barrier. This layer protects the down from water, which allows air to become trapped between the down particles. The down particles, made out of little bifurcations, hold on to that air.


The down particles that hold onto air create a layer of insulation, that holds on to the body temperature of the goose when she’s in the water, in snow and everywhere in between. It is therefore not the down particles that are warm, but rather a network of air and down particles that hold onto body temperature. And it works the same way with humans, so you’re really sleeping in a cocoon of your own warmth.


This means that a heavier duvet doesn’t necessarily mean it’s a warmer duvet. The bigger the down particles, the less of them you need to fill a duvet. Bigger down particles can also hold on to more air, as they have more bifurcations which creates a better layer of insulation. A lighter weight duvet can thus be warmer than a heavy one.


It is therefore important to know whether you’re a hot or a cold sleeper, because no one enjoys waking up in a sweat! If you get cold easily, you’ll need a better layer of isolation that can hold on to your body heat well. If you tend to run hot you’ll need a duvet that allows some body heat to escape.

Fja-Oeyen has been making different types of duvets in different sizes for over 60 years, and our classics never disappoint! Are you a fan of our cassette system or our channel system? Not exactly sure what the difference is? Fear not, we’d love to dive into the specifics!


The differences between the two systems become apparent during daily maintenance and washing. 


A duvet can last a lifetime if it’s properly taken care of. One of the most important things in duvet maintenance is air. Down particles have the smallest ramifications that hold onto air. This creates a barrier that insulates and traps your body temperature and keeps you warm at night. That’s why it’s important to shake your duvet daily, so the down particles can absorb air.

This is only possible with a channel duvet, as in a cassette duvet the down particles are trapped in fields. A channel duvet can absorb 2 to 3 times more air! 


If you know you won’t be shaking your duvet daily, then a cassette duvet might be just right for you!


Shaking your duvet also allows the dirty down particles to slide down, making room for the clean ones at the top of the duvet. This of course is only possible with a channel duvet. Because the down particles are trapped in fields in a cassette duvet, they always come into contact with the same body parts which makes them dirty faster.


When a duvet is professionally washed, the down and cover are taken apart and washed separately before everything is put back together when it’s clean. The cover can be reused as only a small amount of stitching needs to be taken out. This is different with the cover of a cassette duvet, which has a lot more stitching resulting in the cover being destroyed when it gets washed.
