Material
Airline seats are designed to be lightweight, but at the same time strong and fire resistant, while also taking into account passenger comfort. A typical design is an aluminium frame with blocks of urethane foam attached to it. In some cases a layer of fire-resistant fabric, for instance Kevlar, goes over this, and at the top is a layer of cloth or leather.
Leather seats are more costly than traditional cloth seats. Even so, several airlines, including some low cost carriers, choose leather not only to present a more "luxurious" product, but also because such seats are easier to clean and prevent spilt liquids from soaking through to the padding.

Famous quotes containing the word material:
“It is not stressful circumstances, as such, that do harm to children. Rather, it is the quality of their interpersonal relationships and their transactions with the wider social and material environment that lead to behavioral, emotional, and physical health problems. If stress matters, it is in terms of how it influences the relationships that are important to the child.”
—Felton Earls (20th century)
“So in accepting the leading of the sentiments, it is not what we believe concerning the immortality of the soul, or the like, but the universal impulse to believe, that is the material circumstance, and is the principal fact in this history of the globe.”
—Ralph Waldo Emerson (1803–1882)
“We soon saw, as he saw, that he was not to be pardoned or rescued by men. That would have been to disarm him, to restore to him a material weapon, a Sharp’s rifle, when he had taken up the sword of the spirit,—the sword with which he has really won his greatest and most memorable victories. Now he has not laid aside the sword of the spirit, for he is pure spirit himself, and his sword is pure spirit also.”
—Henry David Thoreau (1817–1862)
