Leather grades, and what you are actually being sold
No category in a Foshan showroom carries as much loose language as leather. Six terms cover everything, and the gap between two of them is a factor of five in price.
A salesperson says genuine leather and means it — the phrase is technically true of material that is 20% leather dust and 80% polyurethane. This is not usually deception; it is an industry vocabulary that has drifted, and buyers who do not know the vocabulary buy the wrong thing at the right price.
Here is the ladder, from top to bottom.
The six terms
Full grain is the outer surface of the hide with the grain intact, unsanded. It shows the animal's marks, develops a patina and lasts decades. It is the most expensive and the least uniform, which is why volume furniture rarely uses it.
Top grain is the same outer layer with the surface sanded and a finish applied to even out defects. Almost all quality upholstery leather is top grain. It is durable, consistent and takes colour well.
Split leather is the lower layer left after the top is separated. It has no natural grain, so a grain is embossed and a coating applied. It is real leather and it is much weaker; used on sides and backs it is fine, used on seats it cracks.
Bonded leather is leather fibre and dust bonded with polyurethane onto a backing. It is 10–20% leather by content and it delaminates, usually within two to four years. It should not be sold as leather and frequently is.
PU and faux leather are polyurethane on a fabric backing, with no leather content. Good PU is a legitimate material — consistent, cleanable, animal-free — and modern grades perform well. It is only a problem when it is priced as leather.
Microfibre leather is a high-grade synthetic that outperforms split and bonded in abrasion and tear, and increasingly appears in mid-price Chinese sofas. Worth knowing about rather than dismissing.
Half-leather, and why the price looked good
The standard Foshan construction for mid-price sofas is leather where you touch, PU where you do not — top grain on the seat, back and inside arms, matched PU on the outside back and sides. It is a sensible way to hit a price, it is used worldwide, and it is completely acceptable if you know you are buying it.
It becomes a problem in two ways. First when it is sold as full leather, and second when the split point is drawn too tight — a sofa where only the seat cushions are leather and everything else is PU will look mismatched within two years, because leather and PU age differently.
Ask directly: which panels are leather and which are not? Then write the answer into the specification, panel by panel. A factory that answers this clearly is telling you something good about itself.
Testing a hide in the showroom
Look at the back. Real leather has a suede-like fibrous reverse. Bonded and PU have a woven fabric backing, visible if you can see a cut edge or the underside of a cushion.
Press with a thumb. Real leather wrinkles finely around the pressure point and springs back. PU stays smooth or creases in a single fold.
Feel the temperature. Leather warms to the hand in a few seconds; synthetics stay cool longer.
Look at the edges of the panels. Real hide has slight variation in thickness and grain between panels. Perfect uniformity across a large sofa is a sign of a roll, not a herd.
Ask for a cutting. Any serious supplier will give you a 10 cm square sample. Take it home, and if the order is large, have it tested.
Specifying leather properly
Name the grade, the thickness in millimetres — 1.2–1.4 mm is normal for upholstery — the finish type, the colour reference and the panel map. Add the tannery if the supplier will name it, because leather quality tracks the tannery more than the sofa factory.
For projects, specify abrasion and colourfastness requirements and ask for test reports. For any market with chemical restrictions, ask about chromium VI, which has caused recalls in Europe and is a genuine risk with low-cost hides.
And attach the cutting to the signed sample record. Colour language does not survive translation; a physical swatch does.
