A cushion is a padding or a smaller version of a pillow that is a bag filled with foam, feathers, cotton or soft fabric and is used mainly as a back rest while sitting. A cushion is also used as a shoulder rest, travel cushion or pillow or just for decorative purposes. Cushions are more popular on chairs, sofas, cars rather than on beds. Although cushions are used on beds as well, they are used in addition to pillows or throws.
Cushions are available in different materials, designs and sizes. Cushions also come plain as just a bag of soft fabric and can be decorated using cushion covers.
