Down may be composed of whole down clusters, fibers, or plumes (small feathers). “Loft” may refer to the percentage of whole down clusters in the mix, and a higher loft makes the down more resilient and better at containing warmth. [2] X Research source Goose down is more voluminous than duck down, and it is generally more expensive and considered to be finer and more luxurious. [3] X Research source
If you’re looking for a synthetic, squeeze the fiberfill between your thumb and forefinger: if it rubs together smoothly and feels slightly slick, it will be less likely to clump in the long run. [4] X Research source In addition to being hypoallergenic, duvets with synthetic alternatives may be the right choice if you’re maintaining a vegan household. [5] X Research source
Sewn-through construction binds the top and bottom layers of the duvet together in a box pattern, which keeps the fill from shifting within the insert. [9] X Research source Baffle or baffle-box construction utilizes strips of fabric within the duvet to keep the fill from shifting while permitting greater fluffiness or loft relative to sewn-through construction. [10] X Research source Channel construction holds the fill within parallel seams or “channels,” which allows you to move it to different parts of the duvet, such as towards your feet, if you prefer. (If you sleep with a partner, this type of construction permits each sleeper to adjust the fill to his or her preference. ) Gusseted duvets have fabric “walls” around the sides to increase the loft of the fill. They may have either baffle-box or sewn-through construction. [11] X Research source
The material of the duvet should match the material of the sheets in terms of quality, to avoid friction occurring with the duvet.
