You shouldn't be a quality problem, your leather chair depends on whether it is made of real leather or that kind of artificial leather.

Generally speaking, the chair made of leather, he does not have wear and tear, unless it means that you often have people jumping on it, or oh, don't care for it or something like that, but it will not say that it is peeling or something, at most the place where she sews will open the thread.

If leather such as artificial leather and PU leather are put into the chair, his skin will wear out after a long time, such as cracking. Peeling or something.

These are normal wear and tear as you think about the chair. Even if you are genuine leather, you have been doing it for a long time, there will be some traces on her surface and the like, if it is not so new like a new chair like this fake leather, it will be used for three years before it is worn out, and it already feels that the quality is okay.

Then it depends on how many years is the warranty period of this chair? If it's officially three years, it's not a matter of quality.

How to distinguish real and fake leather products?

1.Leather surface: The natural leather surface has its own special natural pattern, the leather surface is naturally shiny, and when the leather surface is pressed or pinched by hand, the leather surface has no dead wrinkles or dead folds, and there are no cracks; The leather surface of artificial leather is very similar to natural leather, but if you look carefully, the pattern is unnatural, the luster is brighter than natural leather, and the color is mostly bright.

2.Leather body: natural leather, soft and tough, and imitation leather products are also very soft, but the toughness is insufficient, and the leather body is hard when the climate is cold. When the leather body is bent by hand, the natural leather is bent back to nature and has good elasticity, while the imitation leather products are bent back to stiff and have poor elasticity.

3.Incision: The incision of natural leather is of the same color, and the fibers are clearly visible and fine. The incision of imitation leather products does not have a natural leather fiber feeling, or the fiber and resin at the bottom can be seen, or the two layers of base cloth and resin glue can be seen from the incision.

4.Leather inside: The front of natural leather is smooth and flat, with pores and patterns.

The reverse side of the leather has distinct fiber bundles, which are fluffy and uniform. The front and back of some synthetic leather products in imitation leather products are consistent, and the luster inside and outside is good and smooth; The front and back of some artificial leather are also different, and obvious base cloth can be seen in the leather; But there are also some leather leather surfaces that resemble natural leather, and there are fluff that resemble natural leather.

Two layers of leather: is a thick leather with a sheet of leather machine to cut the layer, the first layer is used to make full-grain leather or trim leather, the second layer is made of two layers of leather through a series of processes such as finishing or filming, its fastness and wear resistance is poor, is the cheapest one of the same kind of leather.

Characteristics of the second layer of cowhide: its reverse side is the second layer of cowhide, and a layer of PU resin is coated on the surface, so it is also called film cowhide. With the change of technology, it is also made of various grades of varieties, such as imported two-layer cowhide, because of the unique process, stable quality, novel varieties and other characteristics, for the current high-grade leather, ** and grade are not inferior to the first layer of leather.

It's not a quality issue.

The cuffs of the leather jacket, the sail of the pocket, the neckline, the hem and other parts are most likely to be worn, and then fade, when encountering dust, etc., it will form a dark stain mixed with the primary color, do not understand the reason, and think that it is just dirty, let the master wash it, in fact, it is not so simple.

In terms of broken skin, the standard is generally dry friction and wet friction, which are generally less than one value, which are in line with the standard, and beyond the scope of quality problems.

Generally speaking, if it has been more than half a month, it is difficult to say that he is a quality problem, because leather goods are generally more delicate, even if they can be broken with fingernails, it is inevitable that scratches, sweat, foreign bodies, rain, storage environment, and humidity of the air can affect the stability of leather goods. In fact, if there is a quality problem, it will be broken a long time ago, and it will not wait so long.
