Comfortable

Comfortable is an adjective used to describe something that provides ease or relief, physically or mentally. It can refer to a state of comfort—being free from pain or distress—or to an environment, object, or situation that promotes ease of use, relaxation, and well-being. Examples include a comfortable chair, a comfortable temperature, or a comfortable living arrangement.

The word derives from Middle English and Old French confort, from Late Latin confortabilis, from confortare "to strengthen," from con- "with" + fortis "strong."

Usage emphasizes ease, suitability, and lack of discomfort. It can describe tangible attributes like fit, padding, or climate, as well as intangible ones like familiarity or security. The term is often preferred over "cozy" in formal contexts, while "cozy" emphasizes warmth and snugness.

In design, engineering, and ergonomics, comfort is a key objective. Designers assess comfort through user feedback and, when relevant, objective measures such as seating support, thermal conditions, posture, and ease of operation. Comfort can vary by individual factors including body size, posture, clothing, and climate.
