Imagine you are in a special room where people talk about important things. There are chairs for everyone to sit on, but there is one special chair called a faldstool. The faldstool is smaller than the other chairs and it can be moved around easily. It also has a cushion on top for more comfort.
When someone important like a king or a queen comes into the room, they don't sit on a regular chair. They sit on the faldstool because it is a symbol of power and authority. It shows that they are special and everyone else should listen to what they have to say.
So, a faldstool is a fancy chair that only very important people can sit on. It helps them feel more powerful and respected in a room full of people.
