Stairways designed for regular ascent and descent necessitate a vertical component between each tread, commonly referred to as a riser. This structural element forms the back of the step and defines the height of each individual step. A typical example includes staircases in homes and commercial buildings where consistent step height is crucial for safe and comfortable movement.
The presence of risers contributes significantly to the structural integrity and safety of a staircase. They provide essential support to the treads and prevent objects or feet from slipping through the gaps. Historically, risers have been a standard feature in stair construction, reflecting their importance in ensuring reliable and predictable footing. Uniform riser height is crucial for preventing trips and falls, particularly for individuals with mobility challenges or those unfamiliar with the staircase. Moreover, risers contribute to the aesthetic appeal of a staircase by creating a clean, finished appearance.
