What is a "step ladder"?

A step ladder is a portable ladder with steps, often designed for tasks that require reaching higher places, like cleaning or fixing items. It typically has a small platform at the top for stability and a set of steps for easy climbing. Step ladders are commonly made of lightweight materials, such as aluminum or fiberglass, and are equipped with a safety rail or locking mechanism to prevent accidental folding. They are used for indoor and outdoor tasks where a tall, stable platform is needed but where a full-size ladder would be impractical.
