If you’ve ever shopped for a leather sofa or chair online, you’ve undoubtedly come across the term “aniline” before, probably as “full-aniline” or “semi-aniline” describing the leather upholstery on a piece of furniture. While whatever store you were perusing undoubtedly tried to sell you on its form of aniline leather, whether full- or semi-, as superior one, it probably didn’t tell you why it was better, or what "aniline" even means.

If this situation sounds all too familiar, fret not, as this guide will explain just what you need to know about aniline leather.

What is aniline leather?

Aniline leather — sometimes referred to as full-aniline or pure-aniline leather — is top-grain leather that has been dyed with a translucent, pigment-free dye after the tanning process. This type of dye, known as an aniline dye, improves the appearance of the leather but does not alter its color or hide its blemishes — in fact, it enhances them, allowing natural features of the hide like scars to show through. Because of this, only the highest-quality hides with very few markings are selected to undergo the full-aniline process. The dye used also offers some protection against spills, but not a ton.

What is semi-aniline leather?

Semi-aniline leather also undergoes a dyeing process post-tanning, but a more rigorous one than the treatment undertaken by full-aniline leather. The dye used for semi-aniline leather is pigmented, resulting in uniform color throughout the final hide (along with the option for funkier colors that don’t occur naturally in cattle). This more opaque and colorful dye effectively negates any blemishes in the natural hide, allowing for cheaper, more marred hides to be used. In addition to this color treatment, semi-aniline leather also receives an additional protective top coat that protects it from scratches, sunlight and other wear.

Which is better: aniline or semi-aniline leather?

So, which is better for your leather chair or sofa, aniline or semi-aniline leather? Neither is strictly better than the other, as they each offer their own pros and cons, depending on your needs.

Aniline leather is beautiful. Because its dye is translucent, the natural beauty of the leather is allowed to shine through. This natural appearance is a big reason why a lot of people like leather to begin with, and aniline leather will also develop a better patina over time than semi-aniline. Another benefit of aniline leather is that it feels better against the skin.

Aniline leather is softer because it’s less treated than semi-aniline leather, making for a more comfortable upholstery.

Aniline leather is fragile. It will fade in the sun, will stain easily from liquids, can be scratched with only a fingernail and can even dry out if not properly cared for. It requires far more regular maintenance than semi-aniline, and because of the high-quality hides used, it often (but not always) tends to be more expensive.

Semi-aniline leather is far more durable. Because of its protective coating, this leather is resistant to scratches, spills, stains and sun damage, making it a lot more hardwearing and meaning it requires considerably less maintenance. Naturally, this often makes semi-aniline leather the more practical choice for those with kids and pets. But that coating has its downsides, too.

Semi-aniline lacks the buttery softness of aniline leather because there’s more between you and the leather itself. It can feel a bit more artificial (though it is still made with real full-grain leather).

Semi-aniline leather looks less interesting. Purists also tend to dislike the uniform colors seen in semi-aniline leather, feeling it lacks the character and natural beauty seen in aniline leather.

At the end of the day, you'll just have to decide which is more important to you: the natural feel and beauty of full-aniline leather, or the carefree durability of semi-aniline leather. To help you decide, have a look below at some examples of furniture upholstered in each.

Full-Aniline Leather Sofa

Chairs don't get any better-looking than this, and with aniline leather upholstery, it will just get more beautiful as it patinas.
