Inferior sofa injury back sofa purchase should be cautious

Core Tip: The sofa is located in the most prominent position in the living room. It not only affects the overall condition of the home, but also affects the health of the human body. Therefore, you must pay special attention when purchasing the sofa.

The first choice for buying a sofa is to see if the sofa is very comfortable to do. Is it possible to relax every joint of your body? The height of the sofa and the height of the heel should be about 35-40 cm. This height of the sofa is not only comfortable but also not easy to get sick.

In addition to comfort, it is also important to match. The shape and size of the sofa should be judged according to the size of the living room. Do not put the enlarged sofa in the small living room, which will cause the space to be crowded.

The sofa is a large piece of furniture, which often plays an important role in the overall style of performance, so when you buy it, you should measure the overall style of the room before you buy a sofa that suits your living room.

For how to buy a sofa, Xiaobian combines numerous materials to summarize the following points:

First, go to a specialty store or a large well-known furniture and building materials store to buy. On this basis, the goods are compared to three, and the price, quality and service selection are more cost-effective.

For a wide variety of sofa merchants on the market, who should we trust as consumers? Who deserves our trust? Despite the influence of the "Da Vinci" incident and this "Hill Shield" counterfeit incident, many people have already put a big question mark on some so-called furniture brands in their hearts, but we can’t All furniture brands have a negative attitude. Most well-known brands are still guaranteed in terms of quality. It is important to know that it is not a matter of time to build a well-known brand. Smart enterprises will not easily try their own methods. Moreover, relatively speaking, the brand-name sofas in the large-scale stores of specialty stores are generally recognized by consumers in the long-term use, and their quality is stable, the repair rate is low, the warranty period is long, and the after-sales service is also guaranteed.

Second, ask the business for environmental protection materials testing report sofa environmental indicators wood furniture hazardous materials limited amount of harmful substances in wood furniture mainly for two kinds: one is the release of formaldehyde from the sheet and adhesive; one is the furniture surface Soluble lead, chromium, cadmium, mercury heavy metal content in paint coatings. The standard stipulates that the formaldehyde emission in wood furniture is ≤1.5 mg/L, and the heavy metal content in the paint is: soluble lead ≤90 mg/kg, soluble cadmium ≤75 mg/kg, soluble chromium ≤60 mg/kg, soluble mercury ≤60 mg /kg.

Third, look at the quality of the sofa frame. The two pieces of the sofa will be shaken and shaken repeatedly before and after, and if the feeling is good, the frame is firm. The skeleton is generally enclosed in the outer packaging and is not visible to the consumer. However, there are many well-known brands that have the zipper opening on the bottom of the sofa, and the internal structure of the sofa can be easily seen. You can discuss it with the sales staff, open the corner of the zipper to see if the material of the sofa has been dried normally, and whether there is mold and deformation. If there are no bad, no insects, no scars, and made of hard and hard wood without bark or wood wool, and the joint of the material and the material is not nailed, but with a blink or a mouth If you bite and stick to it, there is no problem. If it is closed type, you should know if the sofa frame is strong. You can lift one of the three-seat sofas. Note that when the lifting part is separated by 10cm, if the other leg is also off the ground, the skeleton is strong.

Fourth, look at the quality of the inner cushion. The bottom 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 layered 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.

Fifth, look at the fabrics, sewing sofas, leather and fabrics to buy leather sofas to choose leather. The leather sofa is divided into a full leather sofa and a half leather sofa. The leather sofa is of high value, breathable and environmentally friendly. The leather sofa 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 sofa skin is divided into yellow cowhide and buffalo leather, which are divided into top layer skin, second layer skin and three layer skin according to the number of layers; according to the origin, it is divided into domestic skin and imported skin. Imported skin imported from Italy and Germany with the best quality of the top layer of yellow cowhide, meets strict environmental requirements, high color fastness, good elasticity and breathability, high mechanical strength, especially high tear strength and tensile strength. High quality leather sofas must be made of the first layer of yellow cowhide.

When purchasing a leather sofa, the leather surface should be rich and lustrous, no scars, and the texture of the texture should be fine. Use a fingertip to pinch a place to the top. It should be soft and strong. After the sitting, the wrinkles can be disappeared or not obvious. The leather is fine and good.

There are many kinds of fabric sofas. The seat and back cover of the sofa should be a looper structure. The high-grade fabric sofas usually have a cotton lining. Other dirty parts should be replaced. The sofa fabric should be relatively thick, and its weight is more than 300 g/m2. It must be more durable, and it must be ensured that the surface is not more than 12,000 times. The sofa fabric can be divided into domestic and imported. The special fabrics for sofas produced by European and American professional manufacturers are of good quality, very small color difference, high color fastness, no weft of fabrics, especially some high-grade fabrics for improving antifouling ability, and the surface is also carried out. Special treatment. Imported high-grade fabrics also have antistatic, flame retardant and other functions.

Buy fabric sofas to choose fabric latitude and longitude fine and smooth, no jump wire, no exposed joints, feel the tension. Sewing depends on whether the stitches are even and straight, and the two hands are firmly pressed to see if the seams are tight and the sides of the teeth are round and full. When purchasing a fabric sofa, it is best to buy a fabric sofa with a removable loose sleeve. One of the benefits is that the loose sleeve makes the sofa and the chair neat and rich, and easy to remove. The second advantage is that the sofa can be refurbished at any time. Once the sofa cover is worn out, or if you want to add new ideas, you can order a new set and give a lot of convenience to the beauty of the home. Last but not least, if you keep pets in your home, the fibers of the sofa are easily scratched. You need to consider whether you should buy a tough fiber or buy a leather sofa.

Sixth, look at the cloth and cloth to see whether the fabric is tightly attached to the internal filling, whether it is flat and flat, especially the two handrails and the joint of the seat and the back should be natural and without creases. If it is a round and semi-circular handrail, it is necessary to see whether the arc is smooth, plump and beautiful. The fabric of the floral pattern or the checkered pattern depends on whether the flower shape of the splicing is consistent, whether the square is horizontal and vertical, and there is no inclination or distortion. Finally sit down and try it out. I feel if the inclination of the seat and back or the curvature of the back seat are the same as the waist, back, buttocks and leg bends. Is the height of the pillow and the back right? The arms naturally stretch and open in the usual time; the sitting feel is comfortable, and it is free when standing up. Stand up and look at the fabric on the buttocks, backrest and armrests for pleats that are noticeably slack and can't be recovered for a long time.

Seven, look at the foam sponge high-grade sofa cushion should use a high-elastic foam sponge with a density of 30 kg / m3 or more, the back pad should use a high-elastic foam sponge 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, the seat cushion of the sofa is preferably about 8 cm indentation after sitting down; the back slope of the backrest should be between 92 degrees and 98 degrees, and the convex part of the upper end of the backrest should match the curve of the human neck.

8. The name, specification, quantity, price, amount and material of the sofa must be indicated on the invoice and contract (if it is a leather sofa, it should be indicated whether it is full leather). Ask the merchant or organizer for a product warranty card. Know the name, address, contact person, and telephone number of the organizer and manufacturer to find out the quality problems and contact them in time.
