Benches have historically served as common seating when chairs were reserved for those of higher status. Benches can be made of wood, metal, stone or synthetic materials and range in styles from those with backs and arms to backless styles that can be sat on from either side. Benches are used both indoors and outdoors in various settings like parks, gardens, scenic overlooks, and indoor spaces like churches, schools and courthouses. Specialized benches include picnic tables, church pews, punishment benches and courting benches.
