This ladder has two rungs about 30 cm apart and the frame extends half a foot higher. The frame is a single high bend tube with less flex that folds out and the main pivot feels solid. Each step is a whole. The tread supports are flimsy but seem solid enough. I stood up and felt that my weight wasn't burdening him. The only weak point is the weak safety lock. It's just a small flat piece of metal that you twist as you set up the ladder, and it attaches at one end to the top step support. It doesn't take long to move, so don't make noise when climbing the stairs.
