"Sit down" is one of the first sentences that is learned studying the English language, as if sitting were the easiest thing in the world. Many people, before taking a seat in a chair, observe how it is made and touch the material of which it is composed, if only they like it, sit down (provided that the chair is comfortable), otherwise change the chair. A chair is not a chair, but the mood created by sitting on it or just admiring it.
