Chevrolet: 2006 Monte SS

Does anyone know why some used 2006 Monte Carlo SS cars state leather
surface seats and cloth rear?

Is there a such thing as putting leather on just the surface of a car seat
and not the entire seat is made of leather?

I have an 07 Malibu SS with "Leather surfaces", but the center of the
seats are perforated material...not leather. The only parts of the
seats that are leather are the surroundings
