All of us like having our feet up when we sit in the sofa. Sometimes we curl up with our legs on the sofa, sometimes we put our feet on the sofa table. Very rarely does anyone sit on the sofa like polite people do, with our feet on the floor.

It just isn’t comfortable! Maybe there’s something physiological and evolutionary behind this, or maybe it’s just me, but I really don’t like sitting with my feet far below me. Even on my desk chair, I often find myself with both legs curled up on the chair in some shape.
