Throw pillows have taken their name from their random places on the sofas or on the beds. They are randomly thrown over the sofa to enhance the beauty or for decoration purposes, so they are thrown cushions or pillows. To cover the sofa from dirt or dust, a piece of cloth is usually spread over it. This piece of cloth is kind of thrown over the sofa, which makes it a throw cover. Throw pillows are also a sort of covering on the sofa.
