What is a "stair"?
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.

What is a "stair"?
A stair is a single step in a staircase, designed to provide a surface for people to step on when moving between different levels. Each stair consists of a tread, which is the horizontal part that people walk on, and a riser, which is the vertical part that connects one tread to the next. Stairs can vary in height and depth, depending on the design of the staircase and the building's requirements. They are essential for accessibility, allowing movement between floors in homes, offices, and public spaces. The design and construction of stairs are important for ensuring safety and comfort during use.
