A cushion is a soft bag of some ornamental material, usually stuffed with wool, hair, feathers, polyester staple fiber, non-woven material, cotton, or even paper torn into fragments.
It may be used for sitting or kneeling upon, or to soften the hardness or angularity of a chair or couch.
They can be placed on sunloungers and used to prevent annoyances from moist grass and biting insects.
The cushion is a very ancient article of furniture; the inventories of the contents of palaces and great houses in the early Middle Ages constantly made mention of them.
Cushions were then often of great size, covered with leather, and firm enough to serve as a seat, but the steady tendency of all furniture has been to grow smaller with time.
