Elements of bedding

Name(s)	Image	Description
Bed skirt (also bed ruffle, dust ruffle or valance)		A decorative piece used to cover the boxspring and legs of the bed. It fits between the mattress and boxspring and hangs to or almost to the floor.
Bedspread (also bedcover)		A bed cover, often decorative, with sides that go to or near the floor. Protects bedding, including pillows, during daytime from dust or other contamination. This does not require a bed skirt, and was particularly popular in North America after World War II. May be removed at night and, if wanted, replaced by a coverlet
Blanket		A woven cloth covering used for warmth.
Bolster		A long, narrow and commonly cylindrical pillow filled with down or feathers. Used for decoration or lumbar support when lying against the headboard.
Boudoir pillows (or breakfast pillows)		Small rectangular decorative throw pillows.
Comforter		A bed cover, used like a blanket, that is filled with batting and is not exceptionally fluffy. It is usually reversible and machine-washable. Comforters are usually paired with a bed skirt to form a complete ensemble, as the comforter's sides only go about halfway to the floor. It differs from a quilt in that the layers of a comforter are not quilted together. (Also see "duvet").
Coverlet		Style of bedspread used before the 20th century in America. It usually does not reach to the floor, and does not cover the pillows.
Duvet		A soft flat bag traditionally filled with down or feathers, or a combination of both, and used like a blanket. Usually not as thin as a comforter, but may be referred to as a "down comforter".
Duvet cover		A decorative and protective covering for a duvet. Most duvet covers have a button or tie closure at one end. Australians use the term doona coverrather than "duvet cover". Usually 70-130GSM solid /printed microfiber or 200-300TC solid /printe cotton
European pillow (or Continental pillow)		A Euro or Continental pillow—a large square pillow—is a decorative pillow that sits back against the headboard. These are often placed behind the standard size pillow shams as a backdrop, or on top of standard pillows as a coordinated set with a duvet cover.
European sham (or Euro sham or Continental sham)		a decorative pillow covering which fits a large 29” × 29” pillow
Feather bed		feathers contained within a fabric shell that lies on top of a mattress as a mattress topper. The featherbed will normally have elastic straps or even have a fitted sheet on it so that it fits over a mattress and stays in place.
Flat sheet (or top sheet)		The flat sheet is tucked in around the mattress over the fitted sheet with the fourth side, at the head of the bed, undone. Some duvet or comforter sets do not include a top sheet; the duvet/comforter has a cotton bottom that replaces the sheet.
Fitted sheet		This is the bottom sheet used to fit tightly over a mattress. Fitted sheets are available in a variety of pocket depths, which refers to the thickness of the mattress. Standard North American pocket size is 7 to 9 inches. Deep pocket corners are usually 10 to 13 inches. Extra deep pocket corners are very generous in size, and range from 14” to as much as 22” and used for extraordinarily high/deep mattresses.
Mattress pad Also known as a mattress topper, or underpad.		This is used above the mattress and beneath a bottom sheet to add comfort.
Mattress protector		This is used immediately above a mattress to protect the mattress. Some also protect the sleeper from allergens.
Neck roll		Small cylindrical decorative throw pillows; used for cervical vertebrae support or pure decoration.Neck rolls typically do not have an opening such as a zipper; they are usually sewn closed, although some designs have an integrated opening at the ends.
Pillow shams		Decorative coverings for pillows, often designed with trims, ruffles, flanges, or cording. Shams are normally placed behind the pillows used to sleep on, which would be covered with regular pillowcases.
Quilt		Quilts are types of blankets that sandwich batting between two layers of cloth, and then stitch through all of the layers to hold them together. Patchwork quilts piece together multiple pieces of fabric to make one of the outer layers of cloth.
Sleeping pillow		The medium-sized rectangular pillow that you lay one's head on when sleeping. A sleeping pillow can come in many sizes such as standard (20" × 26"), Queen (20" × 30"), or King (20" × 36") and differing firmness for back, stomach or side sleeping.
Throw pillow		A decorative pillow that comes in numerous shapes and sizes.
