One of the most important uses of natural down and feathers today is in the bedding sector: quilts, pillows and toppers provide warmth and hygrothermal comfort during sleep, as during the night the body expels moisture, the feather absorbs it and returns it to the environment: a characteristic, the latter, that differentiates them from synthetic quilts. Quilts, as well as duvets, pillows and down toppers, are easy to wash, require little maintenance and take up very little space because they can be pressed without losing their characteristics year after year.
