Down pillows are soft, fluffy pillows filled with the soft undercoating of feathers from ducks or geese. They provide excellent support and comfort, making them popular choices for many sleepers. The natural insulation of down helps regulate temperature, keeping you warm in winter and cool in summer. These pillows come in various firmness levels, catering to different sleeping positions. Down pillows are often covered with cotton or other breathable fabrics, enhancing their comfort. However, they may require special care, such as dry cleaning, to maintain their shape and longevity.
