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 lb, seats in higher classes weigh 200 to 300 lb each, depending on their features. We examine the most important technical factors to consider when selecting linear guides for seating applications.
