Uprights are vertical structures that provide support and stability in various contexts. In construction, they are often used as columns or posts to hold up roofs, walls, or other elements of a building. In sports, such as football, uprights refer to the vertical posts at the end of the field that mark the goal area. In the context of furniture, uprights can refer to the vertical components of items like bookshelves or cabinets, which help maintain the shape and integrity of the piece. They are essential for ensuring that these structures remain upright and functional over time.
