Leather is the strongest, most durable and practical upholstery covering and will outlast fabric four to five times.
How Leather Is Created:
From Hide to Leather:
After cleaning and conditioning, hides are sorted according to quality.
Because leather furniture requires large unblemished hides, it is the
most expensive upholstery covering per square foot. The outside surface
of the hide is cut away from the rest and reduced by a series of rollers
to a thickness between 0.9 and 1.4mm. Because the cells are closer
together in this layer, it's the strongest, most supple and durable part
of the hide. The layer below - called the split - is thicker and
stiffer but not as strong.
Types of Leather:
Real Leather, Fake Leather & The Stuff In-Between:
Top Grain Leather: - The outer layer - or top grain - is the most
desirable for furniture. Nature adds its share of markings, often
requiring sanding, protein injection treatments to retain suppleness and
a protective coating. This process - called correction - adds heat and
light protection and makes it more resistant to spills. The more
correction, the lower the quality. Those top grain hides requiring no
correction, the rarest and most expensive are called full grain or full
top grain. These premium leathers are incredibly comfortable because the
leather can breathe. However, they are susceptible to staining and
marking.
Bi-Cast Leather: - Made from the split hide below the top grain, it's
vinyl coated to resit cracking, splitting and peeling. While this helps,
it doesn't come near matching the durability and fell of top grain
leather.
Bonded Leather: - The leather equivalent of particleboard, it contains
only about 17% leather in the backing. What looks like leather is
actually vinyl.
Dye & Protective Coatings:
Full Aniline Dye: - Hides are immersed in a transparent aniline dye
allowing the natural markings to show through then rotated on drums
until the dye completely penetrates from front to back. No protective
coat is applied making the most luxurious of leathers. Generally
reserved for premium leathers, it's also the reason they're so
vulnerable to stains. As it is a natural product, variations throughout
the grain will be seen on the final product.
Semi-Aniline Dye: - Used on corrected leathers. Despite the name, hides
are dyed through but then a layer of pigment is sprayed on top to even
out variations. A thin coat of lacquer seals in the colour, resulting in
leather that's almost as soft as premium leather, yet harder wearing
and protected against fading and staining.
Surface Pigment: - Used only on the cheapest hides, primary bi-casts.
The pigment sits on top and is sealed with lacquer resulting in stiffer
surface. Easily identified because the back is not the same colour as
the front. The raw hide will show through if nicked or scratched and is
susceptible to cracking and splitting.
Quality leather isn't an expense, it's an investment that looks better
the more you use it. There's a place for bi-cast and bonded leathers but
it's a false economy to think they are cheaper. Top grain full and
semi-aniline dyed leathers cost more up front but last longer, age well
and hold their value better.
It's confusing out there. Terms like "All Leather" and "Top Grain
Seating" can lead you to believe you're looking at a quality piece of
furniture when it's just the opposite. If you know what you are looking
for though, it makes it that much easier to ask the right questions.
