Nappa leather seats are covered with premium leather from the skins of calves, kids, or lambs. Nappa leather seats can be constructed of full-grain or top-grain leather. No definitive test exists for Nappa leather, though it’s generally understood to be uncorrected, supple, and high-quality.

Leatherette seats are covered in a synthetic textile that mimics the look and feel of leather. They lack natural leather seats’ suppleness but are more scratch-resistant and require less maintenance.

Automotive leather seats are covered in an upholstery made from animal hides (mostly cowhide) that’s been tanned and coated for color and protection from wear and tear.
