Leather comes from many different sources. Some are obvious, such as cattle, sheep and pigs, and some not so obvious, such as stingrays and ostriches. However, it is how leather is processed that determines which of three main categories it falls into aniline, semi-aniline, and protected or pigmented leather. Advantages: Aniline leather is comfortable and soft to the touch. Since it retains all the unique markings and characteristics of the hide, each piece is different from any other one. Disadvantages: Since it is not protected, aniline leather can be stained easily. It is not recommended for use in furniture for young families or in high traffic areas for that reason. Advantages: While it retains the uniqueness of aniline leather, semi-aniline leather has more consistent color and is more resistant to stains. It can stand up to tougher conditions and isn’t damaged as easily. Pieces upholstered in semi-aniline leather might also be a bit less expensive. Disadvantages: The markings are not as apparent and therefore the piece does not have a unique appeal that aniline leather does. If you are a fan of the more natural-looking aniline leather, then this is not for you. Protected leather has variations in the surface coating, but by adding it as part of the process the manufacturer has more control over the properties of the leather. The coating also adds more resistance to scuffing or fading. Advantages: Protected or pigmented leather is easy to maintain and stands up to different conditions and uses. There are different levels of protection, and you should be able to find a type that fits your needs best. Disadvantages: This type of leather does not have the uniqueness of aniline leather and looks less natural. It can be hard to tell one kind of grain apart from the other because the surface is coated and embossed.
