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.
Super first class seats are the most complex, folding flat
to 180° for sleeping and featuring infinitely adjustable
headrests, footrests, and seatbacks. At a cost of $250,000
to $300,000 per seat - and a spec sheet of 5,000 parts -
designers must carefully consider how each component
contributes to the overall design. To facilitate smooth and
quiet operation, engineers incorporate various linear motion
components into their seat designs.
