Semi-aniline leather is a little bit more hardy than aniline leather because its surface has been treated with a light coat that contains some pigment and this makes it more soil and stain resistant.
Advantages: While it retains the uniqueness of aniline leather, semi-aniline leather has more consistent color and is more resistant to stains.
Disadvantages: The markings are not as apparent, and therefore less unique than aniline leather.
