The 3 in 1 ladder, dolly, and seating system is a portable, device that can function as a set of stairs, a ladder, a seating area, and a cargo dolly. It is a four wheeled dolly, or a two-handle hand truck with two wheels in front, and can extend to become a ladder or various types of stairs, including steps for sitting. It is constructed from durable aluminum, or another appropriate material. The device can convert into a set of stairs with removable guardrails, or a smaller set of stairs that can be used as seating with foldable backrests. It can be manufactured with an umbrella holder and an optional canopy tent.
