That's the trick with samba stairs: the tread depth is normal, but the staircase is shorter—simply because the unused part on the side of the other foot is left out, so structurally only every two steps use one tread depth. This means the staircase indicates which foot you have to start with; otherwise, you walk it normally, almost as usual, so it also feels safe. Of course, the slope feels steeper. For very small children and elderly people who do not (any longer) take the steps alternately, it is uncomfortable. You can carry a flat-screen TV up or down, and even a small sofa. Dishwashers, washing machines, and unassembled rustic cabinets are better left out. And if you have hip problems, you don’t carry sacks of flour there. In apartments, they are popular for sleeping lofts because, even when slightly hungover (or carrying a vacuum cleaner), they are significantly safer to walk than ladders, despite almost the same space consumption.
