Tulsa Public Schools / Elementary and middle school's chairs are dangerous to kids backs.
After many years of going to schools in Tulsa Public School District, and many other schools, I have notice it's chairs. The chairs of schools are very cheap and simple design, very dangerous for kids backs too. Students are made to sit hours in classrooms, sitting in chairs that aren't comfortable. They may not notice it, but I pay much attention to my surroundings.
Schools needs better chairs!
