Duvet
A duvet is a type of bedding used as a blanket, on a bed. They are normally made of a cotton cover, filled with feathers and down or man-made fibres such as polyester, microfibre and hollowfibre. They are soft and comfortable, and keeps the person who's under it warm when sleeping. Additional bed throws (sometimes called a 'snug') may be added in the autumn/fall to add an extra layer of warmth.
