Feather pillows are soft bedding items filled with feathers, typically from ducks or geese. They provide a plush and comfortable sleeping surface, allowing for good support and a cozy feel. The natural materials used in feather pillows can help regulate temperature, making them suitable for various climates. These pillows are often adjustable, allowing users to add or remove filling to achieve their desired loft and firmness. Feather pillows are generally more affordable than down pillows, which are filled with the softer undercoating of birds. Regular fluffing and proper care can extend their lifespan and maintain comfort.
