"down pillow"の定義と意味

What is a "down pillow"?

A down pillow is a type of pillow filled with the soft feathers from the underbelly of ducks or geese, known as down feathers. These pillows are known for being soft, lightweight, and comfortable, providing gentle support for the head and neck during sleep. Down pillows are often chosen for their ability to mold to the shape of the head, offering a plush and cozy feel. They are typically more expensive than synthetic pillows and may require special care, such as dry cleaning, to maintain their softness and durability.
