For every work day, students go to school to study and listen to the what teachers are saying sitting on the chair. It's not good for students to sit on the woody hard uncomfortable chair everyday for so many hours. As an example of my own experience, almost every school that I have attended have a hard chair for students. My butt hurts through the day. What I think the should do it to provide chair with soft seat for students to sit on. This action would improve a lot of the comfortableness for students who sits for a long time.
