1. Identify the quality of mattresses from the material. Most household mattresses use spring mattresses. To identify the quality of a mattress, you cannot judge it solely by the number of springs. The type and density of the spring also affects its holding capacity. Independent springs have stronger supporting capacity than interlocking springs. Since each spring can expand and contract independently, it can support different parts of the body and maintain the natural curve of the spine. On the contrary, interlocking springs are connected to each other and cannot naturally support the body. The low-mounted design of independent springs can also reduce friction between individual springs, making the springs more durable and not affecting sleep. In addition, the denser the springs, the stronger the supporting force, so pay attention to the ratio of mattress size to the number of springs. 0755.teambuy.com.cn/jiaju/ 2. Identify the quality of mattresses from the contamination of fabrics and fillings. Many consumers take it for granted that mattresses are mainly composed of main components such as springs, cloth and sponges, and should not exist. The pollution problem, even if it exists, should not be a big problem. In fact, this idea is wrong. The problem of excessive formaldehyde in soft spring mattresses is also very serious. It is mainly used in bedding materials. In order to save costs, some manufacturers use cloth and sponges with excessive formaldehyde in bedding materials. The formaldehyde problem is easily decomposed. 3. Identify the quality of the mattress from the product label. When consumers choose a mattress, it is best to choose a large manufacturer, because the product name, registered trademark, manufacturing company or manufacturer name, address, Telephones and faxes are all available, and some products are equipped with certificates of conformity and credit cards, making such products more secure. 4. Identify the quality of a mattress based on its softness and hardness. The harder the mattress, the better, nor the softer, the better. The softness and hardness of the mattress should be moderate. Because only a mattress with moderate softness and hardness can perfectly support every part of the body and evenly support every part of the body according to the curves and weight of the human body. Sleeping on an unsuitable mattress for a long time will affect the health of the spine, especially for children who are growing and developing. A mattress that is too soft or too hard will destroy the natural physiological curvature of the spine.
