Top grain leather is leather from the uppermost layer of a hide. It is the highest quality part of the hide.

Pigmented Leather is any top grain leather to which a clear topcoat and pigments have been applied. The pigments are what usually give the shiny even top color to the leather. The leather may or may not be aniline dyed. Sometimes the pigments (color) are applied to a base crust of a different color and in this case the leather in not dyed all the way through. Leather is usually pigmented to give it durability and hide its natural blemishes. Pigmented leathers are easy to maintain and have maximum resistance to wear, soiling, and fading from light.

Non-Pigmented leather is leather to which no pigments have been applied. These are usually hides of the very best quality and have been aniline dyed for color.

Pure Aniline is top grain leather that is dyed for color without any pigments applied. These hides will exhibit some natural characteristics such as healed scars, scratches, neck and belly wrinkles. Expect color variation from the swatch to the actual leather, due to the fact leather is a natural product and will absorb dye differently within the hide and from hide to hide. This leather will develop a rich patina over time and will fade with prolonged exposure to sunlight.

Protected aniline leather is a top grain leather that is dyed for color and then receives pigment to ensure color consistency. Without pigment a protected leather is not color consistent. The pigment also ensures fade resistance and helps the leather wear over time. A clear water based topcoat is applied for additional protection. The natural imperfections of the hide are also less noticeable. Hides average 50-55 square feet. Protected Aniline Leathers are easy to maintain and have maximum resistance to wear, soiling, and fading from light.

Semi-Aniline leather is pure aniline leather that has a small amount of pigment or clear finish thus allowing the natural characteristics of the hide to still show through while offering some of the benefits of color consistency and increased wear ability.

The ILD rating tells if the material is soft or hard. The higher the ILD rating, the firmer the foam will be.
