When airline passengers travel in coach class, expectations are fairly low with regard to comfort. For example, most seats only offer two positions: straight for takeoff and landing, and a slight recline for the journey. Coach seats are relatively simple and lightweight structures compared to their more sophisticated counterparts in business class, first class, and super first class. Whereas a coach seat weighs approximately 100 pounds, seats in higher classes weigh 200 to 300 pounds each, depending on their features.
