A cushion is a soft bag of some ornamental material, stuffed with wool, hair, feathers, polyester staple fiber, non-woven material, 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.
Cushions and rugs can be used temporarily outside to soften a hard ground. They can be placed on sunloungers and used to prevent annoyances from moist grass and biting insects. Some dialects of English use this word to refer to throw pillows as well.
