I built the storage step using my own measurements as it's designed for adults. It is used for reaching the very highest shelves in my floor-to-ceiling wardrobe system.
It was my first project using my jigsaw and am very happy with how it turned out.
I added some rubber non-slip mats stuck down so no one goes flying when stretching for clothes!
Have a look at my blog for more pictures and information.
