Now that you've returned to your chair, try and feel the way in which the pieces of the chair affect your back.
If you've just sat down, you're probably near something like a 90° angle.
Sitting upright against the chair puts both forward (from the chair's back) and downward (from gravity) pressure on your spine. Over the course of this sentence or paragraph or class, you may have noticed yourself sliding downwards and forwards until your spine is curved into the chair, due to these two pressures.
