Are Katzkin interiors 100% leather?

Virtually all mid-market cars have leather-trimmed seats, which means that part of the seat is covered with leather and part is covered with high-quality synthetic material.

Katzkin leather content reflects the leather content provided by the car
manufacturer, which normally includes full leather seating surfaces in the
front seats and a combination of leather and synthetic materials in the rear
seating areas. We use only premium automotive leathers and synthetics, which
are designed to meet or exceed the quality of the leather interior option
offered by the manufacturer.
