Leather terminology can be confusing because 'grade', 'grain' and 'finish' describe different things. Understanding the basics makes it easier to compare leather sofas without relying on labels alone.

Top grain leather
Top grain refers to leather taken from the upper layer of the hide. Depending on the finishing process, it can range from highly natural-looking to more uniform in appearance.
Do not treat 'top grain' as a complete quality description by itself. The finish and construction still matter.
Full grain leather
Full grain leather retains the natural grain of the hide with minimal alteration to the surface. Natural variations and markings may remain visible.
This makes each hide visually distinctive. With suitable care, the surface can develop character over time.
Corrected grain leather
Corrected grain leather has been mechanically or chemically treated to create a more uniform surface. Pigmentation or other finishing processes may be used to achieve a consistent appearance.
It can be practical and visually consistent, but the final feel depends on the specific finish.
Grain is not the same as finish
This distinction is important. Full grain and corrected grain describe how the hide's surface is treated or retained, while aniline and semi-aniline describe finishing/dye characteristics.
When comparing two sofas, ask the retailer to explain both the leather construction and the finish.
What should you ask before buying?
- What part of the hide is being used?
- How much of the natural grain remains?
- What surface finish has been applied?
- How does the finish affect cleaning and maintenance?
- Is the leather used on all contact areas or only selected areas?
