Few questions cause as much debate in bedrooms as this one: Do you need two duvets in a double bed, or is one large one enough? Anyone who looks into double bed duvets will quickly realize that it is about more than just looks. It is about how warm you feel, undisturbed sleep – and quite practically, which bedding you will need afterwards. We have compiled the most important arguments for you.
In short: For most couples, two duvets are the better choice – but only if their warmth preferences differ or one person is a restless sleeper. If you sleep similarly warm and quietly, one large duvet is cozier. In the end, the duvet alone is not the deciding factor, but rather the combination of duvet size, bed width and bedding quality.
Two duvets: the option for undisturbed sleep
Two separate duvets are the most common solution in German-speaking countries – for good reason. The most important advantage: Everyone has their own warmth preference. While one person may start sweating under a light duvet at a room temperature of 18 °C, the other may still feel cold even in winter. With two duvets, everyone can choose the warmth rating that suits them without compromise.
The second advantage is at least as important: If you toss and turn at night, you won't pull the duvet away from your partner. Restless sleepers benefit noticeably from this, as every nightly awakening interrupts the sleep cycle. You can read more about how the combination of duvet, bedding and room climate affects sleep in our guide to the right bed climate.
There are also several hygienic advantages: Two smaller duvet covers are much easier to wash in a standard household washing machine than a large 200x200 cover, which fills the drum on its own. And if only one person catches a cold, only one set needs to go into the wash.
The disadvantage: A gap forms between the two duvets through which cool air can enter. If this bothers you, place the duvets slightly overlapping or choose two 155x220 cm duvets instead of 135x200 cm – the extra width closes the gap almost completely.
One large duvet: closeness instead of a dividing line
The shared duvet – usually 200x200 cm or 200x220 cm – has its own strengths. It creates a continuous, seamless bed appearance without a gap, and many couples simply find it cozier. You also save time when making the bed: one cover instead of two.
It works best when both partners have similar warmth preferences and sleep quietly. If needs differ greatly, it quickly becomes a compromise that leaves neither person completely satisfied. A practical tip: For a 200x200 duvet, you will also need a mattress or bed frame of corresponding width, otherwise the duvet will hang down on one side. We explain in detail which dimensions are intended for what in our guide to bedding sizes.

The right bedding for your decision
Whether one or two duvets: The material also determines how warm it gets under the duvet. This is because the bedding is the layer that lies directly on your skin.
For those who feel cold, Flannel bedding is the classic answer: With around 160 g/m² and a very high fluffiness, it reliably retains body heat – biberna invented this quality in 1968 and still offers it in original quality today. It becomes even softer and gentler with Melange Flannel, our further development of the Flannel quality.
Those who sweat easily, on the other hand, should opt for TENCEL with its high moisture absorption or smooth, cool Mako Satin. And this is exactly where the often overlooked advantage of the two-duvet solution lies: You can combine different materials. One side Flannel, one side TENCEL – both can sleep in the way that suits them best. You can find an overview of all qualities in our bedding collection.
Specifically, this means: Those who feel cold should choose the biberna Fine Flannel bedding (0006722) from approx. €49.95 or the even fluffier biberna Melange Flannel bedding (0840500) from approx. €49.95. Those who sweat should choose the biberna Tencel bedding (0470500) from approx. €49.95 – it regulates moisture and is washable at 40 °C. For the second set or guest bed, the Castell Fine Flannel bedding in Sapphire (0030988) from approx. €25.95 is sufficient.

Frequently Asked Questions
What size do I need for two duvets in a double bed?
The standard is 135x200 cm per person. Those who are taller or want to close the gap in the middle should choose 155x220 cm. Make sure that the bedding fits the duvet size exactly.
Is one large duvet less hygienic?
No, but it is less practical to wash: A 200x200 cover takes up an entire drum. Wash it alone and with enough space so that it gets properly clean.
Can I combine duvets of different warmth ratings?
Yes, this is one of the biggest advantages of two duvets. It will still look harmonious if you choose the same bedding color and only vary the filling or material.
Are two duvets also worth it in a 140 cm wide bed?
Yes, but with smaller duvets. Two 135x200 cm duvets will hang significantly over both sides of a 140 cm bed. In this case, either a shared duvet or a narrower duvet size is the better solution.
Our conclusion: Two duvets are the more comfortable choice for most couples – especially if their warmth preferences differ. The large duvet remains a great option for everyone who sleeps similarly and values a seamless bed appearance. Whichever option you choose: With the right quality directly from the manufacturer, you cannot go wrong in either case.
