If you want to know if the natural filling or synthetic best suits your duvet, the first step is to determine the ideal weight and warmth for you. You still don't understand concepts like "grams per square meter" or "index from 1 to 6" well, do you? Here are some clarifications that should help you find your way toward your goals.
Details on Grammage and Heat Index
-The weight of the duvet lining, expressed in grams per square meter, is called grammage. Additionally, it provides information about the temperature gauge of this item. There is a wide range of available grammages, from 175gr/m2 for the lightest duvets to 500gr/m2 for the warmest duvets.
The weight of the duvet has an effect on the perceived amount of heat, and thus on the index. Keep in mind that weight varies, and even if some sleepers will not be disturbed by a heavy duvet, others will not be able to fall asleep if they feel "wrapped up" by it.
-Heat index: as we said above, it depends on the weight of the bedding, so you can adapt it to the season and your preferred sleeping environment. The usual range for the index of temperature is from 1 to 4, while some stores may use a larger scale, up to 6 for extreme heat. You can choose between a duvet with a mild temperature, medium or high, depending on the situation.
For those concerned about the environment (and their electricity bills), the heat index is crucial; switching to a warmer coat is preferable to increasing heating.

Which duvet to choose for this season?
Whether it is the light cut of summer
The tempered duvets and light (with a heat index of 1-2) are ideal for summer months or if you keep your bedroom at over 22 degrees Fahrenheit year-round. They are also a good choice if you tend to overheat and sweat easily.
The warm duvet for autumn or spring
During shoulder seasons (autumn and spring), when it is not quite cold enough to take out your winter duvet from storage and not quite warm enough for the summer version, opt for a pair of warm mittens with a heat index of 3 or 4. Similarly, if your room stays cool year-round, or if your room is sufficiently heated but you still feel cold, a mid-season duvet can be a must-have in your decor all year round.
The very warm duvet for winter
To combat the winter cold, opt for warm gloves with a heat index of 5 or 6. Those who like to sleep in a cool room or cold room will feel right at home in such a space, while those who stay cold even wrapped in a blanket appreciate the warmth.
Different weights for natural and synthetic fills
You know there are two types of fillings: natural and synthetic. Natural fillings are more expensive, but they last longer. Another distinction is that a synthetic filling will make a synthetic duvet significantly heavier at an equivalent heat index.
Similarly, a natural duvet is less bulky (but still keeps you warm) when its down content (relative to feather content) is higher.
You can expect a grammage of about 180 g/m2 for a summer duvet composed of 90% down and 270 g/m2 for a winter version of the same design. It is recommended to use 300 to 450 g/m2 of synthetic insulation in winter and 200 to 250 g/m2 in summer for the same level of thermal insulation.

Here is another clever design by the 4-season duvet creators: the thermostatic duvet. Temperature regulation at bed is crucial for restorative sleep. Thus, these duvet models must be able to adapt to your body and room temperature to offer you unparalleled support during your sleep.
Dodo is the place where you can get your hands on the filling fiber, which was developed after many years of study. The cuffs are made of microcapsules and tiny strands of silicone that fight moisture while helping the body maintain a constant core temperature.
