Generally, when choosing a sofa, we all pay more attention to whether the style of the sofa is the favorite, whether the style is consistent with the overall style of the home, and whether the price is reasonable. But we should consider these factors while not forgetting to pay attention to the quality of the sofa itself. Good quality is naturally excellent to the details, then we will pay attention to the details! Detail 1 fabric pattern Generally speaking, the thin fabric of the printed pattern is cheap because of the simple process; while the pattern and the like are woven, it is thicker and higher. When you purchase, carefully observe the pattern of the fabric. The pattern woven by different latitude and longitude lines has a three-dimensional effect, which is not as smooth as a printed fabric. In addition, the fabrics made of pure cotton and pure wool are higher than those of ordinary rayon. Detail 2 fabric leather Modern industry can cut layers of thick cowhide, so there is a layer of skin, two layers of skin and even multiple layers of skin. A layer of skin is the outermost layer. This layer of leather has good toughness and elasticity. After being made into a sofa, it is not easy to be broken after repeated pressure. It is a high-grade fabric. You can see the top layer with a special magnifying glass. The pores of the second layer are the remaining skin of the lopsided skin. The surface tension and toughness of the second layer are not as good as the top layer, so it needs to be carefully selected. In addition, it is made of large pieces of leather, or is spliced ​​by small pieces of leather, which is also an aspect that affects the grade. Detail 3 sofa cover Be sure to check carefully for ease of disassembly for future cleaning in use. Detail 4 sofa interior The inner quality of the sofa is also a circle that cannot be ignored. When the general purchaser buys a sofa, if it is only sitting and sitting, it is difficult to judge the pros and cons of the sofa. The only way is to take a look inside. For some sofas that are not all-inclusive, you can turn over and observe the quality of the springs, plates and sponges used to judge the quality of the sofa. A good sofa, the internal spring requires anti-rust treatment, the wood used requires planing, no scars, etc. Detail 5 frame Nowadays, European-style sofas adopt the structure of frame and cushion. In order to present some special design feelings, some designs will deliberately expose a part of the frame, such as exposing shiny metal, which is commensurate with the leather material to create a wild and unrestrained effect. . Then the partially exposed frame should be checked to see if the gloss is textured. Detail 6 sofa feet Some sofa feet are made of wood, some are metal, and some are pulleys. This detail should be checked carefully. Mainly to be strong, the feet are not stable, the sofa will not be comfortable to sit up. Details 7 Humanization The armrests and backrests can expand the range of services, the placement of tea sets, the embellishment of trinkets, and the shelving of free books on hand. Optical Spectrum Instrument is a data acquisition device that can simultaneously collect target spectral information and pattern texture information. While collecting target edge texture information, it can also obtain spectral features of different spectral segments of the target.
