A 'blanket' is a type of
bedding, generally speaking a large, rectangular piece of cloth, intended to keep the user warm, especially while
sleeping. Blankets are distinguished from
sheets by their thickness and purpose; the thickest sheet is still thinner than the lightest blanket, because blankets are for warmth, while sheets are for hygiene, comfort and aesthetics. Blankets are subdivided into many types, including
quilts,
duvets, and
comforters, depending on their thickness, construction and/or fill material.
Electric blankets are heated by
electricity. Blankets were traditionally made of
wool because of wool's warmth, breathability and natural fire-retardant properties, while sheets were made of
cotton or
linen, which are less irritating to the skin. These days,
synthetic fibers are frequently used for both. Throw blankets are smaller blankets, often in decorative colors and patterns, that can be used for extra warmth outside of bed.
Etymology
There is speculation that the name blanket is derived from Edmund Blanket, a 14th century clothier and wool merchant and
Member of Parliament from
Bristol, who is buried in
St Stephen's Church, Bristol.

Blankets may also be used on the
ground for a
picnic or other places where people want to sit in a grassy or muddy area without soiling their clothing. Discardable blankets have been designed for this purpose, although their inherent wastefulness is a chief concern of several environmental groups.
Use in firefighting
Specialized blankets may be used by
firefighters to protect furnishings from water damage during firefighting. Firefighters often wear specialized variants of the fire blanket to protect themselves as well. The term can also be used to refer to air/liquid foam coverings sprayed on liquid fuel fires — a ''foam blanket''.
Use in moving of household goods
Thick quilted and durable blankets are used as protective covers and cushioning when furnishings are moved.
Use in horse care
A warming coat for a horse is called a ''
horse blanket'', intended to prevent the development of a shaggy winter coat of hair. A small ''
saddle blanket'', protects the horse's skin from chafing by the pressure points of a
saddle.
