Frontcannon Posted January 12, 2011 Share Posted January 12, 2011 You seen those ergonomic chairs? The ones that you virtually kneel on but maintain an upright body position? They are supposed to be excellent for backs. Sitting absolutely straight (~ 90°) is actually worse for backs than sitting leaned back.
