If the most important piece of furniture in the living room is? There is no doubt that it is a sofa. As a must-have furniture in the home, the sofa has a long replacement cycle and needs to be matched with the home style, so you need to be more careful when choosing. When buyers choose a sofa, they should pay attention to the following aspects:
1. Look at the frame of the sofa. As a large piece of the sofa, the frame structure should be firm. When checking, you can use both hands to shake the whole piece of the sofa back and forth and shake it vigorously. If it feels better, the frame is firm. Then look at the underside of the base fabric, no decay, insects, scars, burrs, etc.
2. Look at the comfort of the sofa
A sofa is an object used to sit or lie down. Sometimes the role is a chair, and sometimes the role is a bed. Therefore, when buying a sofa, it is best to sit on the spot and feel the hardness. Sitting on a sofa that is too hard can cause muscle soreness, while a sofa that is too soft will have the feeling that the whole person is trapped inside. It is not comfortable to sit for a long time. In addition, the height of the sofa also needs to be referenced, generally with the height of the coffee table in front of the sofa.
3. Look at the material of the sofa The current sofa has three kinds of wood, leather and fabric.
The real all-wood sofa is very expensive and affordable for the average person. Generally speaking, wood sofas only use a small part of solid wood raw materials, and other parts use high-density boards and other boards. When selecting a wooden sofa, the hardness and wood grain of the wood determine the quality of the wood. The higher the hardness, the more beautiful the wood grain, the more precious the material and the higher the price. Of course, the color difference of the wood surface represents natural, but there is no cracking and irritating odor to avoid excessive formaldehyde in the processing.
Cloth sofa has won the favor of many users because of its fashionable, economical, practical and beautiful characteristics. Choosing a cloth sofa mainly depends on the height and filling of the material of the cloth: the general filling is a sponge, and the fabric sofa using a high-density sponge would be better. Some sofas on the market use raw cotton and granular cotton, which is difficult to meet environmental standards. In terms of fabrics, silky fabrics, satin, coarse linen, corduroy and other wear-resistant fabrics can be used as sofa fabrics. The sofas of silk and satin fabrics are elegant and luxurious, giving a feeling of grandeur; the sofa made of coarse linen and corduroy is solid. Heavy. It depends on the buyer's needs.
Leather sofas are divided into full leather sofas and half leather sofas. Each set of leather sofas consumes the equivalent of 10 cows of cows, which is of high value, good ventilation and environmental performance. It is commonly used in developed countries such as Europe and America. The semi-leather sofa replaces the cowhide with PU leather or artificial leather PVC on the back, bottom and other hidden parts of the sofa, but the direct contact part of the human body is still a higher value cowhide, which reduces the cost of the sofa and is more economical. The pros and cons of the leather can be judged by touching the surface of the leather. It feels smooth, soft and plump. In addition, a good dermis can also be seen as a concave-convex shape with clear pores and patterns. After the test, the wrinkles can be disappeared or not obvious after being trimmed.
4. Look at the cushion layer The underside of the high-grade sofa seat and the back of the back are mostly made of nylon belt and snake spring cross-web structure. The upper layer is covered with high-elastic foam, sprayed cotton and light foam. This cushion rebounds well and feels comfortable. The mid-range sofa is mainly made of rubber fiberboard as the base and the bottom of the back. The upper layer is layered with medium density foam and sprayed cotton. This cushion has a harder sitting feel and a slightly less resilience. High-grade sofa cushions should use high-elastic foam sponges with a density of 30 kg/m3 or more. The back cushions should use high-elastic foam sponges with a density of 25 kg/m3 or more. In order to improve the comfort of sitting and lying, some foams are soft-treated under the premise of ensuring no reduction in density, and some are provided with vertical springs in the seat cushions, so that the sofa has higher resilience and anti-aging properties. Under normal circumstances, it is best to have a sofa cushion of about 10 cm after sitting down.
5. Look at the details. For example, the seat and back cover of the fabric sofa should be cleaned for the structure of the loop; whether the warp and weft of the fabric is fine and smooth, no jump wire, no exposed joints, and the hand feel is not strong. If the leather sofa has a big smell, it means that the quality of the leather is not good, and it is probably artificial leather. The size, style and color of the sofa should match the entire room. Try to choose a big brand sofa, so the after-sales service is more secure. For more information on furniture, please pay attention to Xianghe Furniture City official website http://
