Many consumers believe that furniture is the heavier the better, in fact , it should be the same material the heavier the better. Some of the furniture will be used in the leftover material even the bark of material to fill the backrest of a sofa or the side of the armrest, it is not light, but use for a long time will be broken. Generally inexpensive sofa use hardwood, useful pine. The inner frame uses northeast larch, It is harder than general pine is not easy to deformation and firm. The wooden frame is mainly used by yellow poplar, no deformation, no cracking and texture clear. Auxiliary structure of the frame also has the single panel, WDF, plywood etc, not only a great different in material quality, environmental performance is also very different, especially formaldehyde content, you have to consider. (The details of process: the cost of use polished flinch is higher than non-polished flitch, good furniture reflected in the details, it also reflects the intention of the factory.)
The frame is generally enclosed in the outer packing, consumers can not see it. However, there are a number of well-known brands of the bottom of the sofa drapery with a zipper, you can easily see the internal structure of the sofa. If it is closed, and you want to know sofa frame is firm, you can lift one end of the three seat sofa, pay attention to when the lifting part 10cm off the ground, then if the other end of the legs also off the ground, the frame is firm. The bottom of a good sofa can see the internal structure, you can clearly see the advantages and disadvantages of the internal timber, an ordinary sofa is made with the black mesh cloth to cover simply.
2.The elasticity of the cushion is better.
The sofa cushion has two types, one is spring package, one is a sponge. The low-end sofa use serpentine spring(vertical spring), foam rubber and doll cotton, it is not durable and rubber hardening will be uncomfortable, so it can only use for three to five year. The mid-range products use a firmer high elastic bandage and not easily deformed lateral S-shaped spring, the filler mainly uses high rebound memory sponge. The cushion should choose density of more than 35kg/cubic meter high elastic foam sponge, backrest should choose density of more than 25kg/cubic meter high elastic foam sponge, so not easily deformed. Other places use more than 20 density sponge.
The filler of sofa has cotton, generally placed on the sponge to increase the softness and comfort of the sofa. The corner of sofa and inside of the backrest is filled with cotton, it is soft, feel smooth, warm, comfortable and good permeability. High-grade sofa used eiderdown, which should be the best filler, is it warm, comfortable, good permeability and a strong sense of sitting.

Use the hand to press the sofa arm and backrest, if can obviously feel the wooden frame, it is proved that this set of sofa packing density is not high and flexibility also not good enough. Easily feel the wooden frame can accelerate the wear of the sofa sets and not durable.
The surface of the sofa with leather and cloth based, including artificial leather, microfiber leather, PU leather do not consider.50% of the cost of leather sofa is cowhide, which imported from Italy, head layout cowhide is the best, its crust is flexible and firm, the leather not much processing, feel smooth and soft, light smell and more environmentally friendly.
