Scandinavian couples worked something out generations ago: sharing a bed does not have to mean sharing a duvet. The Scandinavian sleep method is having a moment in the UK, and its bigger sibling, the so-called sleep divorce, is losing its stigma too. Here is how both work, what each one actually fixes, and the problem neither can solve.
Quick answer: The Scandinavian sleep method means one bed, two single duvets, so each partner controls their own warmth and nobody's duvet gets stolen at 3 am. It fixes duvet hogging and temperature arguments overnight, costs almost nothing, and you can start tonight. A sleep divorce, sleeping in separate beds or rooms, is the stronger remedy for snoring or completely clashing schedules, and sleep scientists increasingly treat it as a practical choice rather than a relationship failure. Neither fixes a partner's tossing and turning travelling through the mattress; that is a motion isolation problem, and it is solved by pocket springs, not bedding.
What is the Scandinavian sleep method?
The Scandinavian sleep method is the practice of sharing one bed but using two separate single duvets instead of one shared double. It is the default way couples sleep across much of Norway, Denmark and Sweden, which is why hotel beds there routinely come made up with two single duvets folded side by side. Each partner picks their own duvet weight, wraps or kicks off as they please, and the nightly tug-of-war simply has no rope.
Why do couples sleep with two duvets?
Because most duvet arguments are really temperature arguments. Two people rarely run at the same warmth: one sleeps hot, one cold, one wants the winter duvet in October and the other holds out until December. A shared duvet forces a compromise that suits neither, and every roll-over by one sleeper tugs at the other. Separate duvets end the hogging, let a hot sleeper pair a light summer duvet with a partner's warmer one all year round, and remove one of the two big ways partners wake each other. The Sleep Foundation notes that sleeping with a partner is linked to feelings of security and better subjective rest, so keeping the shared bed while separating the bedding keeps the good part of co-sleeping and drops the worst part.
How do you set up the Scandinavian sleep method in the UK?
Two UK single duvets (135 x 200 cm) sit side by side almost perfectly on a king size bed, which is the classic setup; on a UK double they overlap a little more, and on a super king there is room to spare. Choose each duvet's warmth independently, make the bed by folding each duvet in half lengthways side by side, hotel-style, or lay them flat and overlapping, and use a single large throw or bedspread on top if you want a made-bed look for daytime. There is nothing else to it, which is rather the point.
What is a sleep divorce, and is it bad for a relationship?
A sleep divorce means partners sleeping separately, in twin beds or in different rooms, as a deliberate choice rather than a drift. The name is unhelpfully dramatic: the research picture collected by the Sleep Foundation suggests couples who choose it usually do so to protect sleep, not to escape each other, with snoring and incompatible schedules the two biggest drivers, and many report better rest and less resentment as a result. The honest framing is that it is a strong remedy with real trade-offs, less incidental closeness and a step most couples prefer not to need, which is why the two-duvet method is the better first move for everything except noise.
If snoring is what is driving you to separate rooms, treat the snoring before splitting the household: our guide on how to stop snoring covers the fixes with evidence behind them, from sleep position to when a GP should be involved.
What does neither method fix?
Movement through the mattress. Two duvets do nothing about a partner who turns over forty times a night, and even separate duvets on a bouncy open-coil bed will transmit every turn; if that is the true culprit, couples end up blaming the duvet or fleeing to the spare room when the mattress was the problem all along. Motion isolation is a construction question: individually wrapped pocket springs absorb movement at the spring where it happens instead of passing it across the bed, and memory foam above them damps what is left.
That is the strength of a pocket sprung and memory foam build, and it is worth checking before any furniture-rearranging: our best mattress for couples guide covers the full decision, and every model in our hybrid mattress range uses tall premium pocket springs with open-cell memory foam. The 5000 Lux Elite goes furthest, with 5000 springs in two layers for the best motion isolation in the range, which is exactly the spec a light sleeper sharing with a restless one should look at.

Which should you try first?
Work up the ladder from the cheapest fix. Start with the two-duvet method for temperature and hogging, since it costs a spare duvet and one night's experiment. If broken sleep continues, ask what is actually waking you: movement points at the mattress, noise points at the snoring guide and only then at separate rooms, and clashing schedules can often be softened with the routines in our guide to staying asleep all night. A full sleep divorce is the right answer for some couples, but it is the last rung, not the first.
Scandinavian sleep method FAQs
Why do Norwegians have two duvets?
Tradition and pragmatism: across Norway, Denmark and Sweden, couples habitually sleep under a single duvet each, and hotels make beds up that way by default. Each sleeper controls their own warmth, nobody loses the duvet in the night, and the shared bed stays shared.
What size duvets do you need for the Scandinavian sleep method?
Two UK singles (135 x 200 cm) on a king size or larger bed is the standard setup. On a smaller double the two singles overlap more but still work. Choose each duvet's warmth independently; mixing a light and a warm duvet on one bed is the whole point.
Is a sleep divorce a sign of a failing relationship?
No. Couples who choose to sleep separately usually do it to protect their sleep from snoring or clashing schedules, and many report less resentment and better rest as a result. It is a practical remedy with trade-offs, which is why gentler fixes such as separate duvets, snoring treatment or a motion-isolating mattress are worth trying first.
Does the Scandinavian sleep method stop a partner's tossing and turning?
No. Separate duvets fix temperature and duvet hogging, but movement travels through the mattress itself. That is solved by individually wrapped pocket springs, which absorb each movement where it happens; a bed with poor motion isolation will transmit turns whatever the bedding arrangement.
