A duvet is a type of bedding or bed covering, similar to a quilt or a comforter. It is a soft, flat, cloth bag filled with down, feathers, wool, or a synthetic material. Like a big, flat pillow (the size of a whole bed), a duvet is protected by a duvet cover. If we compare a duvet to a pillow, then we can think of the duvet cover as the big pillowcase. This removable cover allows you to change the appearance of your comforter or quilt bedding easily, adding variety to your room design from time to time, simply by switching from one duvet cover to another duvet cover. A duvet cover can also be removed and washed, to ease the chore of whashing an entire thick bed covering everytime you want to freshen it up a bit. ... The images in this gallery, then, are designed specifically to fit the dimensions of a duvet cover for beds of different sizes: King, Queen, Full, or Twin. Just choose your size and order. ...
