The Bed by Henri de Toulouse-Lautrec depicts two people under a blanket
A blanket is a type of bedding, generally speaking, a large 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.
Blankets are generally used 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.
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. Nowadays, 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. Blankets are sometimes used as comfort objects by small children.
The term arose from the generalization of a specific fabric called Blanket fabric, a heavily napped woolen weave pioneered by Thomas Blanket (Blanquette), a Flemish weaver who lived in Bristol, England in the 14th century. Earlier usage of the term is possible through its derivation from the French word for white, blanc.

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. Temporary blankets have been designed for this purpose, although their inherent wastefulness is a chief concern of several environmental groups.
