For thousands of years, humans have rested on the ground using variations of a squat, cross-legged or a kneeling position. And despite the availability of chairs and things to sit on, sitting on the floor is still common in many cultures. According to reports, many English-speaking people refer to floor sitting as "Indian style," though it's also known as "Turkish style." In Korea, it's called "Yangban style" -- named after the traditional ruling class. While in Japan, the formal way to sit is called "seiza," which involves sitting on the heels with the knees resting on the floor.
