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:
“Would it not be worth while to discover nature in Milton? be native to the universe? I, too, love Concord best, but I am glad when I discover, in oceans and wildernesses far away, the material of a million Concords: indeed, I am lost, unless I discover them.”
—Henry David Thoreau (1817–1862)
“I do not deny the existence of material substance merely because I have no notion of it, but because the notion of it is inconsistent, or in other words, because it is repugnant that there should be a notion of it.”
—George Berkeley (1685–1753)
“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.”
