A bed canopy is a decorative fabric structure that hangs over a bed, often supported by posts or a frame. Traditionally, canopies were used to provide privacy and warmth, especially in large, drafty rooms. Today, they serve mainly as a stylish addition to bedroom decor, creating a cozy and inviting atmosphere. Canopies can be made from various materials, including cotton, linen, or sheer fabrics, and come in different styles, such as four-poster or mosquito netting. They can also be used to enhance the aesthetic of a room, adding color and texture while providing a sense of enclosure and comfort.
