What is Full Grain or Corrected Grain Leather?

Leather is a highly desirable furniture upholstery material, priced for its durability and comfort.  The ultimate symbol of natural beauty and ultimate luxury.

Comparison between Corrected Grain and Full Grain

What is the difference between corrected grain and full grain is a FAQ and we would like to tell you. As these are the two most popular types of leathers used for upholstery.

Let’s look at Corrected-grain leather:

Corrected grain leather is also referred to as CG leather. Over years scars and markings will appear on the skin as the animal is exposed to the African field.  Tanneries try to get rid of these markings with the following process: Firstly deep holes and marks are filled with a leather filler.  The top layer of the skin then gets shaved away to get rid of all remaining marks.  The leather is now without any markings, but it is also stripped of its natural grain.  Big heated metal plates are used to emboss a grainy print on the leather.  After the leather has gone through this process it is called corrected grain as opposed to full grain leather which has not gone through this process.  It looks uniform due to the fact that most of the natural grain has been removed and it is given a semi-aniline coated finish or more often, pigmented dye (protective dye).

Of course, not all leather is created equal.

Full-grain leather:

This is the most natural, most durable and most expensive leather used for high-end upholstery.  Full-grain leather has only been dyed in a drum and has no pigmentation on top. The removal of the animals’ hair leaves the leather with its natural grain, marks and scars visible. Full-grain leather is usually treated with transparent vegetable dye called “aniline” or dyed and then coated called “semi-aniline”. This finishing process helps to protect the colour and make leather suitable for the manufacturing of furniture and other products. The appearance of full-grain leather is very natural and alive, but it is slightly less colourfast and stain-resistant than semi-analine leather.
