Nowadays, many families who have been renovated in the spring have entered the stage of selecting furniture. Faced with a wide variety of products on the market, how to choose durable furniture, many consumers have no bottom. In this issue, we invite experts to conduct a classification guide for sofa selection.

Fabric sofa

Fabric washing method can know the grade

According to the sales manager of a furniture company, the seat and back cover of the sofa are preferably loopers, and the zipper should be smooth and reasonable in length. Although some manufacturers are loopers, in order to save fabrics, the length of the zipper is short, and it will be more difficult to remove and wash in the future. If there is a tear-proof elastic at the bottom of the zipper, it means that the workmanship of the sofa is more delicate and more humane. High-grade fabric sofas generally have a thick cotton lining. This lining prevents dust from entering and prevents the feathers from falling out of the bag.

"The fabric of the sofa should be thick and durable and can not afford the ball." According to the place of origin, the sofa fabric can be divided into domestic and imported. According to the material, the sofa fabric can be divided into five series. First, cotton and linen fabrics, relatively rough, breathable, very cool, but feel rough; second, pure cotton fabric, feel comfortable; third is the three anti-cloth fabrics, mainly anti-static, oil-proof, anti-proof Stain, also known as suede. In addition, there are chenille and cut velvet, which are relatively high-end. The products imported from Europe and the United States are of good quality, small color difference, high color fastness and high integrity. The surface is generally treated with special features, anti-static, flame retardant and so on.

High-grade fabrics require more dry cleaning. If the salesperson says that it can be hand-washed or machine-washed, it is mostly blended fabric. After the fabric is washed, it is best to dry it directly. It is best not to use a washing machine to dehydrate it, so as not to damage the texture of the fabric.

Work and look up to check the quality

The inner material mainly includes a backrest and a seat cushion. Generally good sofas will use high-rebound high-density polyurethane sponges. The sitting layer and the bag will have down feathers, which is more comfortable and easy to fit into various people's body types. Experts suggest that in addition to choosing a high-density sponge, you should also choose a drawstring and a serpentine spring. Generally speaking, the ribs of the imported good belts are round, and the domestically produced partial belts are flat.

The frame of the general sofa is made of solid wood frame, mostly birch. This kind of wood has high strength, high density and large bearing capacity. In addition, if necessary, the salesperson can open the base cabinet to see that the wood is smooth, without bark, breakage, insects, smashing, etc., and requires horizontal and vertical, without circular curvature.

In terms of sitting, it should be felt that the internal filling is flat and full, and there is no crease at the seams. The patterns of the mosaic and the lattice should be spliced. In addition, it is also possible to lift a corner of the sofa, and if the remaining triangles are also lifted up, the overall structure is relatively stable. If the other horns do not move, there is something wrong with their structure.

leather sofa

Zhu Changling, vice chairman of the China Furniture Association, pointed out that most of the leather sofas currently on the market are leather sofas for the main parts. Although the leather and leather feels different, it is difficult to distinguish. Li Zizheng introduced a small trick to everyone: hold the surface of the leather with your fingers, if there are small folds around the collapse, then it is cortex, otherwise it is imitation leather. And many sofa samples will be attached to the instruction manual of the sofa, which introduces the material of the sofa, and consumers can also look at the reference when purchasing the leather sofa.

Light Translucent Concrete

Opical Fiber Concrete which is New, safety and high quality
* Low-loss optical window in the light-visible area, and ability to transmit visible light from end to end, but not including ultraviolet or infrared light
* The impression given by traditional concrete is always murky, but this dark-colored, lifeless concrete may be about to become a thing of the past. combining traditional concrete with fiber optics cable can produce transparent concrete. Combining the fair-faced concrete technology with light-guiding materials, through product research, the light-transmitting concrete is made into garden building products, decorative plates, decorative blocks, transparent concrete bricks, wallboards, etc
* As long as the light is shining on one side of the light-transmitting concrete (monochromatic light or 7 color light), it will be able to see these lights (non-guided infrared light) from the other side of the concrete. These lights can be both chaotic and heavenly like the star in the sky; it also can be arranged in different shapes according to actual needs, such as characters, text, drawings, etc.. Because the concrete itself has solid, heavy-duty, thermal insulation, light and transparent materials, and concrete composite can be made into garden construction products, decorative plates, decorative blocks, can also be used to make a variety of building materials.
* Light-transmitting concrete has a good working performance and a wide application prospect, as follows:
- Light transmission concrete light guide material is evenly distributed and has good light transmission performance. It can transmit visible and infrared light of different wavelengths, which greatly saves the general architectural lighting loss. It is a kind of green and low carbon building material. Works of different textures and colors have significant architectural energy-saving and decorative effects.
- Light-transmitting concrete has good thermal insulation properties and is used in accordance with related materials. It can be used in indoor fire escape, night guidance, and other special fields, and improves the safety of buildings, especially high-rise buildings.
- Compared with ordinary concrete, the light-transmitting concrete's bending strength is greatly improved, and various shapes can be made according to building requirements, which expands the practicality and applicability of building materials.
- Light-transmitting concrete This type of wall itself has a high appreciation value. It has great potential for application in hotels, restaurants, villas, and other buildings that require decoration, and provides a material basis for further improving the architectural aesthetic effect.
* No conductivity or heat transfer(Through the fibers no electrical power is sent, they remain always cold )
* Reduced energy cost
* No electrical hazard
* Long life-time
