Stairs are a series of steps that allow people to move between different levels of a building or structure. They can be made from various materials, such as wood, metal, or concrete, and are designed to provide safe and easy access. Stairs can be found in homes, offices, and public places, and they often include handrails for support. There are different types of stairs, including straight, spiral, and curved designs. Each type serves a specific purpose and can vary in size and shape. Stairs are an essential part of architecture and are often considered in the design of buildings to ensure functionality and safety.
