Understanding the composition and structure of sofas and avoiding purchasing traps








沙发框架有3种:实木、板木、钢结构实木结构——由于木材资源的紧缺,硬杂木的烘干技术、榫卯连接等均有技术难度,加之真正实木结构的沙发相当昂贵,此类结构环保性好,使用寿命长。板木结构——木方做横梁和直立支撑,结合多层复合板采用钉接方式制成的结构骨架。此种结构材料成本较低,制作工艺简单,成型方便,制造效率高,是目前广泛采用的一种工艺。全钢焊接结构——普通标准方钢管在标准模具下焊接成型,进行防锈处理。此种工艺成型难度大,工时长,技术要求高。优点是结构稳定性好,强度高,环保好,使用寿命长。我们在选购的时候,应该让商家提供样品,如果允许的话,我们要在验货的时候查看其沙发框架的材料,看是否是我们定制的那种。
There are three types of sofa frames: solid wood, board wood, and steel structure. Solid wood structures - due to the scarcity of wood resources, the drying technology and mortise and tenon joints of hard and miscellaneous wood are technically difficult. In addition, sofas with real solid wood structures are quite expensive. These types of structures are environmentally friendly and have a long service life. Board wood structure - a structural framework made of wooden beams and upright supports, combined with multi-layer composite panels and nailed together. This type of structural material has low cost, simple manufacturing process, convenient molding, and high manufacturing efficiency, and is currently widely used as a process. All steel welded structure - ordinary standard square steel pipes are welded into shape under standard molds and undergo rust prevention treatment. This process has high difficulty in forming, long working hours, and high technical requirements. The advantages are good structural stability, high strength, good environmental protection, and long service life. When making a purchase, we should ask the merchant to provide samples. If allowed, we should check the material of the sofa frame during inspection to see if it is the one we customized.








沙发面料:要分清全皮和非全皮、真皮和仿皮沙发面料有皮面和布面。皮面又分真皮、人造革。真皮按层数又可分为头层皮、二层皮、三层皮,按产地分为国产皮和进口皮,进口皮以黄牛皮品质佳,环保、色牢度高、弹性和透气性好,机械强度高,te别是撕裂强度和抗张强度高。布艺面料的密度关系到沙发长期使用的机械磨损寿命,国家标准沙发布艺面料的密度大于300G/M,且必须确保摩擦12000次以上表面不起球。那么如何分辨真皮和仿皮?据左右沙发西安负责人陈岱军介绍,,用手触摸皮革表面,如有滑爽、柔软、丰满的感觉则是真皮;人造合成革手感发涩、死板、柔软性差。第二,真皮有较清晰的毛孔、花纹,黄牛皮有较匀称的细毛孔;人造合成革一般没有毛孔。第三,真皮点燃后会发出类似烧头发的气味,不结硬疙瘩;人造革燃烧后会发出刺鼻的气味,结成疙瘩。沙发坐面:沙发易塌陷多是拉簧绷带质量差坐面是沙发受力的主要部位,也是沙发舒适性和使用寿命长短的关键性部位。
Sofa fabric: It is necessary to distinguish between full leather and non full leather, and between genuine leather and imitation leather. Sofa fabrics have leather and cloth surfaces. The leather surface is divided into genuine leather and synthetic leather. Genuine leather can be divided into top layer leather, second layer leather, and third layer leather according to the number of layers. It can be divided into domestic leather and imported leather according to the place of origin. Imported leather is made of high-quality yellow cowhide, which is environmentally friendly, has high color fastness, elasticity and breathability, and has high mechanical strength, especially tear strength and tensile strength. The density of fabric is related to the long-term mechanical wear life of sofas. According to the national standard, the density of fabric for sofas is greater than 300G/M, and it is necessary to ensure that the surface does not pilling after friction for more than 12000 times. So how do you distinguish between genuine leather and faux leather? According to Chen Daijun, the person in charge of Left and Right Sofa in Xi'an, touching the leather surface with your hands, if there is a smooth, soft, and plump feeling, it is genuine leather; Artificial synthetic leather has a rough and stiff feel, with poor softness. Secondly, genuine leather has clear pores and patterns, while cowhide has more uniform and fine pores; Synthetic leather generally does not have pores. Thirdly, after igniting the genuine leather, it will emit a smell similar to burning hair, without forming hard lumps; After burning, artificial leather will emit a pungent odor and form lumps. Sofa seat surface: Sofa is prone to collapse due to poor quality of tension spring bandages. The seat surface is the main part of the sofa that is under stress, and it is also a key part of the sofa's comfort and service life.










沙发的坐面结构主要有橡筋绷带(弹性好但使用寿命短,易出现塌陷)、木平板(无弹性,坐感差但使用寿命长)、蛇型钢簧(弹性好、坐感好、使用寿命长)。沙发坐垫下面多采用蛇型拉簧和尼龙绷带连接,有的是拉簧加绷带,有的是只用绷带。拉簧需要有很强的韧性才能保障时间久了不变形不断裂(变形容易塌陷,断裂容易刺穿坐垫,还可能伤人)。好绷带里面的皮筋是90根,差的绷带多为45根皮筋,弹性差。沙发填充物:高回弹海绵比较好 但当心掺假海绵填充物:用于沙发填充的海绵主要分三大类:常规海绵具有较好的回弹性、柔软性、透气性;高回弹海绵具有优良的机械性能,较好的弹性,压缩负荷大,耐燃性、透气性好;乱孔海绵弹性好,压缩、回弹时具有ji好的缓冲性。羽绒填充物:羽绒做沙发填充物,坐感舒适、长期使用变形小,缺点是回弹慢,成本也高。
The seating structure of sofas mainly includes rubber band bandages (with good elasticity but short service life, prone to collapse), wooden flat plates (without elasticity, poor seating sensation but long service life), and snake shaped steel springs (with good elasticity, good seating sensation, and long service life). The sofa cushion is often connected with snake shaped tension springs and nylon bandages, some with tension springs and bandages, while others only use bandages. The tension spring needs to have strong toughness to ensure that it does not deform or break over time (deformation is prone to collapse, fracture is prone to piercing the seat cushion, and may even harm people). There are 90 rubber bands inside a good bandage, and most poor bandages have 45 rubber bands with poor elasticity. Sofa filling material: High rebound sponge is better, but be careful of adulteration Sponge filling material: Sponges used for sofa filling are mainly divided into three categories: conventional sponges have good rebound, softness, and breathability; High rebound sponge has excellent mechanical properties, good elasticity, high compression load, good flame resistance and breathability; Random porous sponge has good elasticity and good cushioning properties during compression and rebound. Down filling material: Down is used as a sofa filling material, which provides a comfortable sitting experience and minimal deformation after long-term use. The disadvantage is slow rebound and high cost.
