Which duvet for which season?
Summer duvets
These are duvets that are often filled with cooling materials or less filling weight is used. This makes you sweat less and sleep more comfortably.
Winter duvets
Are duvets that are suitable for the cold season. In the case of down and feather duvets, those with a higher inner or outer bar are usually used. In general, a higher filling weight is used for winter duvets, so the duvet is significantly warmer than other duvets.
4-season duvets
This is two duvets that can be connected together if necessary, but can also be disconnected again. This is usually done by means of a snap fastener or small ribbon, in the case of down duvets often by connecting buttons. One duvet is a summer duvet, the other is a transitional or all-season duvet. Connected together, the duvet can be used as a winter duvet. This duvet is suitable for people who do not want to have several duvets.

What is a heat class?
When it comes to buying a duvet, quality and comfort are key, and it's easy to get confused by terms like "duvet warmth rating", but this is actually a really useful one guide to find the right duvet for you.
While the "warmth class" does not refer to the quality of the duvet, it does give an indication of the warmth of the material, which ultimately affects the comfort of the duvet refers, depending on what you prefer. Here's our short "Duvet Warmth Rating Explained" guide to finding the right duvet for you.
Duvet warmth class explained
A heat class rating can range from 2 to 5. At the lower end of the scale are lighter duvets that are mostly used in the summer months, while the higher ones are much better insulated and are typically winter duvets.
The most commonly purchased warmth class duvets are between 3 and 4 um to guarantee warmth, especially during the long and cold winters in Germany. Some people prefer two duvets - warmth class 2 for summer and either class 3 or 4 for winter.
If you want a year-round solution, there is the option to buy an all-season duvet. These are two duvets that clip together to provide the perfect solution for year-round use. You can take out a duvet in the summer when you get too hot and then add another one in the winter. The All Season Duvet is a Warmth Class 2 duvet with snaps attached to a Transitional & Winter Duvet giving you three duvet options in one.
Weight doesn't mean warmth!
We encourage you to do your own research before investing in a duvet set as you are looking for the warmth that suits you and quality that will last for many years. When it comes to warmth ratings it is about it mostly a matter of personal preference and the level of warmth you prefer.
Typically, a 100% down duvet, such as our Hungarian goose down duvet or our European duck down duvet, is much lighter than a feather or synthetic down duvet, as it has a higher degree of warmth and consequently less filling is required to achieve a high warmth class. This makes the duvet feel lighter on the body, but offers excellent warmth with no cold spots.
Of course, your budget is an important factor here, as natural down and feather fillings will be a more expensive option than unnatural fillings.
Worth knowing
A thermal class rating is not only influenced by the type of fabric or filling, but also whether a cooling fabric is used for the cover and the fabric used for the outer cover.
High quality duvet fillings such as goose and duck down provide excellent insulation and retain heat very well. High-quality synthetic brands such as Dacron® and Comforel® trap more air and therefore retain their warmth compared to other cheaper synthetic alternatives.
Natural 100% cotton duvet covers offer extra breathability, whereas microfiber or polyester duvet covers tend to cause heat build-up and therefore less effective at dissipating moisture.
Everything you need to know about thread count:
The higher the thread count of the duvet cover, the softer the feel. Thread count refers to the number of threads per square inch of fabric. The higher the thread count, the more threads per square inch and the finer and softer each thread feels.
Standard duvets with feather rich content or Dacron® Comforel® filling are made in a fabric with a thread count of 233 thread count. The higher quality down and premium synthetic options use a 300 thread count to ensure the best possible result for the desired product and to achieve unparalleled softness.
Everything you need to know about filling performance:
The fill power can range from 300 to 900 and above. The most common down products have a rating of 400 to 500, but these are considered to be of poor quality as they come from immature geese and ducks and are therefore made from smaller tufts of down. When shopping for a quality down fill jacket, you should look for a fill power of at least 550. A jacket of this caliber will be both warmer and more comfortable.
For example, a fill level of 600 down means that one kilo of down can cover 600 cubic meters. In this process, the down is placed in a Plexiglas cylinder and lightly compressed with a weight.
