The Philosopher says: your average chair has four legs (or one leg with a branched base, but let us not speak of office furniture), which really makes it a special case of the ideal Table. Tables are for setting things on; chairs are for sitting in. Should their different purposes not be reflected in different appearances? Well, exactly. The shape of the Spring chair is obviously related to the human body: more than anything else, you sit down in its lap. And a very welcoming lap it is.
