The Scandinavian Sleep Method: Why Couples Sleep Better With Two Duvets

Half past one in the morning. The duvet has gone. Not partially, not a bit askew, gone, wrapped around a person who is sleeping beautifully and has no idea any of this is happening. You are lying there in the cold air doing the maths on how long until the alarm.

It is one of the most common complaints about sharing a bed. In our 2026 UK Sleep Survey, 33% of people who share or have shared a bed named duvet hogging as one of the things they find most annoying, and 23% said their partner gives off too much heat. Both have the same fix you can try, and Scandinavians have been using it for generations.

The Scandinavian sleep method is a sleeping arrangement where a couple shares one bed but uses two separate duvets instead of one shared duvet. Each person picks their own size, tog rating, and filling. You still share the bed, the pillow talk, and the goodnight. You simply stop sharing the covers.

It also goes by the Scandi sleep method, though “method” rather oversells it. In Sweden, Norway, and Denmark, and in Germany and Austria too, two duvets on a double bed are simply how a bed gets made. Hotels do it as standard. Nobody there thinks of it as a hack.

The name caught on in the UK and US in late 2023, after Swedish content creator Cecilia Blomdahl, who lives on the Arctic island of Svalbard, showed how she and her partner make their bed. It went round the internet, acquired a name, and became a trend, which is a slightly funny fate for something Scandinavians have done for as long as anyone can remember. Double-size duvet covers are reportedly quite hard to buy over there.

It comes down to three things. None of them are complicated, which is exactly why it works so well:

Your body cools down to fall asleep. Sleep onset and a drop in core temperature happen together, which is part of why a hot bedroom is such a common cause of a broken night. Warm skin is a different matter. Warming the skin increases blood flow near the surface so heat can escape, and in one small study, gently warming the skin reduced the time it took people to fall asleep by about a quarter, roughly 3 minutes.

What that means in a shared bed is that you and your partner may genuinely need different things. One of you needs to shed heat. The other has cold feet and wants to warm up. A single shared duvet cannot do both. Two duvets can, because you each choose your own tog.

Our guide to the best temperature for sleep goes into the numbers, and if you are the one who is always freezing, why you get cold at night is worth a read.

You can starfish. You can curl up. You can stick one leg out, which is a legitimate thermoregulation strategy and not a personality flaw. None of it drags the covers off the person beside you.

This is the part that makes the Scandinavian method different from the alternatives. You are not moving to the spare room, and you are not buying a second bed. You are staying exactly where you are and removing one point of friction.

Honest answer: no one has tested it directly. There is no study comparing couples with one duvet against couples with two, so anyone quoting you a percentage improvement has got it from somewhere other than the research.

What we do have is good evidence about the things it targets. A review of bed-sharing research across couples, parents and children, siblings and pet owners found something that fits this rather neatly. Across the board, people reported sleeping better when sharing a bed, even though the objective measurements were generally worse, with more awakenings. The authors pointed to movement and heat as the main things working against sleep in a shared bed.

Therefore, the bit couples love about sharing a bed—being close to someone—is not the bit causing the trouble. The trouble is heat and movement. Two duvets sort out both and leave the good part completely alone. The theory is sound, the proof is missing, and your own bed is the only laboratory that matters here. Give it a fortnight and see how you get on.

There really is not much to it. Get the sizing right, and the rest looks after itself:

• Two single duvets, whatever size your bed is: A single duvet each works on a double, a king and a super king. You want a little overlap in the middle so there is no cold gap between you.
• Pick your own tog: This is the whole point, so use it. Hot sleepers want something light; cold sleepers want more. Our duvet buying guide runs through tog ratings and fillings.
• Sort your pillow out while you are at it: Side sleepers need more loft than back sleepers, and a pillow that suits your position does more for neck ache than any amount of duvet admin.
• Deal with the look: Let the two duvets meet in the middle, or throw a large blanket or bedspread over the top during the day, and the bed looks entirely normal.
• Keep the cuddling: Share one duvet while you talk, read, or watch something, then roll back under your own when it is time to actually sleep.
• Give it two weeks: The first couple of nights will feel odd for the same reason any change to your bed does. Judge it on how you feel in the afternoons rather than how novel it feels at eleven at night.

If you fancy taking the theme further, our Scandi bedroom ideas cover the calm, pared-back look that goes with it, and bedroom ideas for couples have more for a shared room.

It is not the right answer for everyone, and there are a few genuine catches:

• Small beds make it tricky: On a double or smaller, two duvets can feel bulky. Two narrower singles with slight overlap usually solve it, though a larger bed works better.
• Cuddling takes more effort: Not impossible, just less automatic. Couples who like falling asleep tangled up tend to miss it, so this one is worth being honest about between you.
• More laundry: Two duvet covers instead of one to pile in the washer.
• Making the bed takes longer: A little, yes, though we are talking seconds rather than minutes. Fold each duvet in half and lay them side by side, which is how it is done in Scandinavia, and the bed looks perfectly tidy.
• It will not fix everything: Snoring, mismatched schedules, a sagging mattress, and a partner who fidgets are all still there in the morning. Two duvets solve temperature and covers, and that is the honest limit of it.
