Certofied Scaffold works.

When Safety truly matters, you must trust the sense and judgement of two qualified engineers. Seeing the need to refill a water bottle to further their needs in another part of the yard, these two have mastered the techniques of balance by evenly distributing weight and height to their utmost. Task was accomplished, both were able to get up and down without harm--probably because in our family prayer, all who love them asked that no harm and danger might befall. Hey, if it works, it works.
