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. A cushion is also referred to as a bolster, hassock, headrest and a sham. Cushions and rugs can be used temporarily outside to soften a hard ground.
