A canopy bed is a type of bed characterized by its four posts, one at each corner, that extend above the mattress. These posts can support a fabric draping, creating a cozy and enclosed sleeping space. Canopy beds are often made from wood or metal and can vary in style from traditional to modern designs. Historically, canopy beds were used for privacy and warmth, especially in large, drafty rooms. Today, they are popular in bedrooms for their aesthetic appeal and can be found in various styles, including those inspired by Victorian or modern decor.
