A stair is a series of steps designed to connect two levels within a building, allowing individuals to move from one floor to another. Typically enclosed within the structure, stairs consist of horizontal surfaces called treads for stepping on and vertical sections known as risers that support the treads. They can vary in design, including straight, curved, or spiral configurations, depending on the layout and space available. Stairs are essential for accessibility and can be constructed from a range of materials, such as wood, metal, or concrete, providing both functionality and aesthetic appeal in the interior design of a building.
