As the days grow shorter and temperatures drop, our sleep patterns change as well. We go to bed earlier, pull the blanket up higher, and seek closeness with our partner. This isn\u2019t just about coziness. Physical closeness is soothing, provides warmth, and can even affect the quality of our sleep. <\/p>\n\n\n\n
At the same time, many couples are familiar with that little nightly tug-of-war: one person rolls over, taking the blanket with them, and the other is suddenly left out in the cold. This rarely has anything to do with thoughtlessness. Most of the time, the blanket is simply too small for two. <\/p>\n\n\n\n
The 220 x 240 cm<\/strong> comforter solves this problem. It is sized so that two people can fit comfortably under it together, even if they move around in their sleep. <\/p>\n\n\n\n For a long time, it was assumed that couples sleep better on their own. People who sleep next to someone else move around more and are disturbed more often. However, a research team led by sleep researcher Henning Johannes Drews of the University Medical Center Schleswig-Holstein in Kiel came to a surprising conclusion. <\/p>\n\n\n\n For the study, twelve young couples spent several nights in a sleep lab, sometimes alone and sometimes together. In addition to their body movements, their brain waves, breathing, and heart activity were also recorded. While the participants did indeed move slightly more when they were together, this did not result in poorer sleep. The REM phases\u2014that is, dream sleep\u2014were actually longer and less frequently interrupted when the participants slept together.<\/strong><\/p>\n\n\n\n REM sleep plays an important role in processing emotions and experiences. Researchers therefore suspect that sleeping together may contribute to greater emotional balance. In addition, the study showed that the couples\u2019 sleep patterns became more similar to one another, and this trend was stronger the closer the relationship was perceived to be. Since only a small number of couples were studied, the results cannot be generalized. However, they do offer an intriguing insight into why closeness feels so good at night. <\/p>\n\n\n\n Our bodies themselves provide part of the explanation. When we are touched or have physical contact, our bodies release the hormone oxytocin<\/strong>. It has a calming effect, reduces stress, and thus makes it easier to fall asleep. You can read more about this in our article \u201cOxytocin\u2014How the \u2018Cuddle Hormone\u2019 Promotes Restful Sleep<\/a>.\u201d <\/p>\n\n\n\n Then there\u2019s the issue of warmth. Sleep specialists recommend a bedroom temperature between about 16 and 19 degrees, since the body needs to cool down slightly at night to sleep soundly. Under a shared blanket, two people keep each other warm. There\u2019s no gap in the middle for cold air to seep through, and cold feet<\/a> are forgotten more quickly. This way, you can combine a cool bedroom with a cozy, warm bed. <\/p>\n\n\n\n A representative survey conducted by YouGov in the spring of 2026 on behalf of the online retailer Galaxus shows just how differently couples in Europe sleep. While in Italy and France about four out of five couples sleep under a shared blanket, in Germany three out of five couples prefer separate blankets<\/strong>. Nevertheless, Germans see the closeness and cuddling as the biggest advantage of sharing a bed. <\/p>\n\n\n\n One detail from the survey is particularly revealing: In France, where sharing a blanket is the norm, one in four people gets annoyed by someone stealing the blanket. This shows what often causes the \u201cpartner blanket\u201d to fail\u2014not the idea itself, but the size. So if you want to share a blanket, you shouldn\u2019t skimp on the size. <\/p>\n\n\n\n The 220 x 240 cm comforter is 220 cm wide and 240 cm long<\/strong>. In stores, you\u2019ll often find the same size listed as a 240 x 220 cm duvet<\/em>. It\u2019s common to list the dimensions as width by length, but not every manufacturer uses this convention consistently. Checking the product description will quickly clear things up. <\/p>\n\n\n\n The generous length has a pleasant side effect: Even tall people have plenty of room and won’t have their feet hanging off the edge when they stretch out. You can find an overview of all standard sizes on our duvet<\/a> page.<\/p>\n\n\n\n The 220 x 240 cm comforter is best suited for double beds that are 160, 180, or 200 cm wide<\/strong>. On narrower beds, it hangs slightly further over the sides, which many couples find comfortable because neither person ends up without a comforter when they roll over. For a bed that\u2019s 140 cm wide, however, this size is usually too large. In this case, a 200 x 200 cm comforter is the better choice. <\/p>\n\n\n\n Since two people share a blanket and keep each other warm, a double blanket often feels warmer than a single blanket of the same warmth rating. If you tend to sweat easily at night, you\u2019re better off choosing a slightly lighter option.
