The surface fabric of comforters can be anything to fit any decor style, but typically they are fully washable. Ready-made duvet covers are usually constructed of a washable fabric, but may require pressing after each cleaning. Custom-made duvet covers may require dry-cleaning.
Comforters fall over the sides and end of the bed an equal amount and are long enough at the head of the bed to cover pillows. There is no need to purchase sleeping pillows and extra pillows for the decorative shams as is typical with the use of duvets and covers. Time is saved by not having decorative pillows to remove and store at night and replace each morning. Sleeping pillows are exposed with the use of duvet and covers, wrinkles and all.
A comforter may have an attached bed-skirt and extra-large comforters may not require bed-skirts at all, whereas duvets and covers require bed-skirts to conceal the box springs and legs.
Comforters cover the mattress and pillows so the bed linen is not exposed during the day as it is with a duvet and cover. The day-to-day reality of mismatched linen is not a problem with comforters.
A comforter is quilted. The outer layers of fabric and inner layer of filler are joined with stitching lines that often follow the pattern of the fabric. This quilting creates design and texture on the comforter, as well as prevents the layers from shifting and separating. Duvet covers are flat, with no dimensional stitching.
Comforters are a traditional style of bed-covering and are well suited to a period or classic style of decor but, depending on the fabric and quilting pattern, may fit contemporary interiors as well. Duvets and covers tend to be found in modern, contemporary design plans rather than classic decors.
