Which duvet do sleep experts recommend?

Sleep experts look for breathability, low weight, temperature regulation, OEKO-TEX® and NOMITE. For most people, an all-season down duvet, vegan Primaloft Bio, is suitable.

In short: Sleep experts look for five criteria in duvets: breathability, low weight, temperature regulation, freedom from harmful substances (OEKO-TEX® Standard 100), and suitability for allergy sufferers (NOMITE). For most people, an all-season duvet with 90% or 100% Class I down meets these criteria best; Primaloft Bio is a very good vegan alternative.

Criteria from sleep experts for the right duvet

Which duvet is best for you? The answer depends on several factors – but there are clear criteria for what can help a duvet contribute to a good night's sleep.

What does sleep research say?

The sleep environment – temperature, light, and bedding – has a noticeable impact on sleep quality. Sleep experts often recommend a rather cool bedroom of around 16 to 19 °C. The duvet plays an important role here: it should retain your body heat without letting you overheat.

Natural down – proven for breathability and temperature regulation

Natural down is considered particularly breathable and good at regulating temperature. The reason is its three-dimensional structure: the fine down fibers trap a lot of air, thus retaining heat and allowing moisture to escape. High-quality synthetic fibers such as Primaloft Bio come close, but do not quite achieve the natural climate of down.

The most important criteria according to experts

Breathability: The duvet must be able to absorb and release moisture
Weight: Duvets that are too heavy restrict your freedom of movement while you sleep
Temperature regulation: Ideally, a duvet should adapt to your body temperature
Freedom from harmful substances: OEKO-TEX Standard 100 is the minimum requirement
Suitability for allergy sufferers: NOMITE certificate for house dust allergy sufferers

Our recommendation based on these criteria

For most people, an all-season duvet with 90% or 100% Class I natural down is a very good choice. It meets all the criteria mentioned above and offers the most natural sleeping experience. If you are vegan or have allergies, Primaloft Bio is a very good alternative – it comes closest to down in all relevant respects.

All Traumwelt duvets and pillows are OEKO-TEX® Standard 100 certified, with down products additionally certified by NOMITE and DOWNPASS – manufactured by German manufacturing partners.

Frequently asked questions

How heavy is a good all-season duvet?
The fill weight is the deciding factor. A Traumwelt all-season duvet in 135 × 200 cm has 624 g of fill with 90% down or 560 g with 100% down – thanks to a fill power of approx. 750 cuin, this is sufficient for normally tempered bedrooms.

What room temperature do sleep experts recommend?
A rather cool bedroom of around 16 to 19 °C is often recommended. If your bedroom is warmer than that, choose a lighter warmth class – see the details in the guide Warmth Classes & Fill Weights.

What is the best duvet for allergy sufferers?
For house dust allergy sufferers, a duvet with a NOMITE-certified cover – this applies to all Traumwelt down duvets. If you react to down itself, choose a vegan Primaloft Bio duvet. Find out more in the guide House Dust Allergy & Bedding.
