A duvet that can be used all year round because it is fluffy and warm in the winter and cool in the summer. If you take proper care of it, it can be used for a long time, so you can use it as a partner for a comfortable sleep. It’s expensive and you don’t have to replace it often, so you’ll definitely want to choose your favorite duvet. Therefore, an expert explains how to choose a duvet and introduces recommended products. We also evaluate.
Advantages of a duvet. Comfortable and easy to care for all year round. And long life
Duvets are made by utilizing the excellent characteristics of waterfowl down grown in regions with extreme temperature differences, and have advantages not found in cotton duvets. Let’s sort out the benefits.

Warmth and moisture wicking properties of down keep you comfortable all year round
Human beings have a sleeping environment in which they feel comfortable when they go to bed. This is a condition where the temperature is around 33 degrees Celsius and the humidity is below 50%. Down, which is used as stuffing for duvets, maintains a comfortable bed environment throughout the year through the “curl phenomenon” that traps and releases heat depending on the temperature and humidity. In addition, it is rich in “draping properties” that wrap around the body and fit, so the duvet does not slip even when you toss and turn, and it is also lightweight.
Duvets are also easy to maintain. Dry in the shade, avoiding direct sunlight. In addition, it is a good idea to occasionally roll up the futon into small pieces to exchange the air contained in the down. When sweat or sebum adheres to the down, it weakens its ability to regulate temperature and breathability, so if the cover or side fabric is very dirty, have it cleaned by a duvet specialist. Also, as a point to note about the storage method, avoid using a futon compression bag, as it will damage the down, and put it in the storage bag that comes with it at the time of purchase. It is said that duvets can be used for 10 years or more if properly cared for.
How to choose a duvet. The origin of the down is the most important. Check down power and sewing
The superiority or inferiority of duvet quality largely depends on the origin and type of down. You can see how much the quality has been improved by the manufacturing process and the manufacturing method of the side fabric, so let’s check it first.

Predict the strength of the curl phenomenon from the origin and type of down
The origin and type of down filling have the greatest impact on the quality of duvets. Basically, down from waterfowl raised in areas with extreme temperature differences is of good quality, and the above-mentioned curl phenomenon is stronger. Eider duck, which is produced in the vicinity of Ireland, is the most expensive type of high-quality production area.

For this reason, the highest grade down that is compatible with the Japanese housing environment is white mother goose down harvested in Poland. Mother goose down from Hungary, Russia, France, Canada, and China is the second most expensive. Down can be harvested from both ducks and geese, but larger gooses produce more down than ducks. Goose is better because each feather is larger and can create a wider layer of air and has a wider range of temperature control. It also has the advantage of making the duvet lighter because it requires less filling.

It can be said that the stronger the curling phenomenon of down, the more functional it is, but the manufacturer does not disclose the strength of the curling phenomenon. Therefore, down power (dp), which indicates how much volume per gram of feathers is, can also be used as an indicator of heat retention. The higher the number, the larger the swelling and the higher the heat retention. As a guideline, 350dp is enough, and if it exceeds 400dp, it will be quite voluminous.
No matter how good the quality of the down is, it is light and has excellent heat retention and breathability. The heat retention power of the can’t be utilized, and deterioration may be accelerated. For this reason, it is common for duvets to have a quilting process on the side fabric to prevent the down from being unevenly distributed.

The main types of quilting are three-dimensional quilting, in which a partition called a gusset is placed between the outer and lining fabrics, and gussets that are different horizontally and vertically between the outer and lining fabrics (2). There are two types of quilts: layered quilts, and facing quilts, in which the outer and lining fabrics are sewn together. Double-layer quilts are more expensive, but of the three, they are the easiest to keep down down from becoming uneven and increase heat retention. It is said that high-quality down that is well quilted and properly maintained will maintain its drape for 20 years.
In order to take advantage of the characteristics of feathers, it is better to use a material with excellent moisture wicking properties for the side fabric. The side fabric is 100% cotton, which is of higher quality than blended materials such as cotton and polyester. In particular, those made of thin and long cotton thread are more functional. Sea Island cotton, Giza cotton (Egyptian extra-long cotton), Xinjiang cotton, and Indian cotton are thin, have good moisture absorption, and can be sewn finely, so the down does not blow out easily.
