Linear Guide Systems Streamline Aircraft Seat Assembly and Operation

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.
