Picking the right duvet

Where and when? We recommend that you purchase both a summer and a winter duvet since very few bedrooms maintain the same temperature all year round. Many of us still have only one “all-year duvet” even if there are more and more of those who are lucky to have several duvets to choose among. Because of the modest amounts of fill they have, summer duvets are relatively cheap to buy. Nevertheless, you can also “do the full Monty” and go on a little dream journey – with a wonderful silk duvet.

How big should the duvet be? To be able to tuck in your body and, in particular, your feet well, the duvet must be at least 30 cm longer than you and at least 30 cm wider than your chest. If you are considering a double duvet to share with your partner, you need to match your needs with theirs before you make the purchase. It won’t do you any good if your partner is sweating while you’re so cold that your teeth are chattering. If you can reach an agreement, you should go for a double duvet that is at least as wide as the bed.

How about content? To determine a duvet’s thermal comfort, just take a look at its fill power. Fill power is an expression of down’s insulating power and thereby of its quality. High fill power indicates that the fill is light, fluffy and provides good insulation. It may sound illogical that a good quality duvet should contain air, but if you put large, flat feathers into a duvet, it becomes heavy and uncomfortable – before it gets warm. Duvets should therefore be fluffy and elastic enough to be able to retain air and thereby body heat as they would otherwise require far more fill. This can be compared with building insulation where, for example, mineral wool is particularly well-suited to preventing heat from escaping outside. Eider down has the best insulating power followed by goose down and finally by duck down. But take a look at the product label because “duck down, fill power 10” denotes a better quality than “goose down, fill power 8”.

And the shell? The shell is available in different qualities, from the always popular cotton cambric to cotton batiste, cotton sateen and silk, all of which are down-proof and Oeko-Tex-labelled. What you opt for is up to you as it depends on range, taste and discretion. And then there is also the price.

And also remember… the product marks! And by this we mean the information you get from the duvet’s labels. Check if the duvet is labelled “Oeko-Tex Class 1”, which means that it does not contain any residual chemicals. Check for a “Nomite” label if you are allergic to house dust mites (Nomite is your guarantee that house dust mites cannot penetrate the shell.) Check for a “Downafresh” if it makes a difference to you that the down has been washed and dried in accordance with strict international rules and can therefore not contain any microorganisms and viruses.
