Comforters are a type of bedding designed for warmth and comfort. They're essentially large, quilted blankets filled with down, feathers, or synthetic materials. Comforters are typically larger than regular blankets, offering full coverage for a bed. They're often used as the top layer of bedding, placed over sheets and blankets. Comforters are known for their softness, warmth, and ability to add a decorative element to a bedroom.
