CCTV weekly quality report hot mattress failure rate exceeds 50%
CCTV News: To build a high quality life together, welcome to watch the "Weekly Quality Report". About one-third of a person's life is spent in sleep, so the quality of sleep is crucial for everyone. The mattress is a very important factor affecting the quality of people's sleep. If the mattress is not comfortable enough, it will definitely lower your sleep quality. If the mattress is not qualified, it is more likely to adversely affect your health. So, is your mattress qualified? In order to better understand the quality and safety of mattress products, the Beijing Consumers Association recently organized a comparative trial specifically for mattress products. Let us first look at the results of the trial.
The Beijing Consumers Association selected 50 mattress products that were popular in the Beijing market and on the Internet, including 37 spring soft mattresses and 13 brown fiber elastic mattresses. The test results showed that among the 50 mattress samples, 25 samples had problems in quality, and the failure rate was as high as 50%.
Luo Gang, director of the Consumption Guidance Department of the Beijing Consumers Association: 40% of the spring mattresses did not meet the national standards, 70% of the brown mattresses did not meet the national standards, and 5 of the 6 mattress samples we purchased on the online trading platform were mixed. False, inferior quality and other quality issues.
According to the requirements of relevant national standards, this comparative test examined various items such as physical properties of mattress fabrics and core materials, hygienic safety indicators such as formaldehyde emission, and product marks.
According to the requirements of national standards, the materials used in mattress products should not have materials that affect people's health and safety. However, in the actual testing process, some materials used in mattress products were found to be unqualified.
Sun Shudong, director of the Furniture Testing Laboratory of the National Furniture Quality Inspection Center: We have not found any products that use used clothing or waste industrial waste during this inspection. There are mainly non-conformities in safety and hygiene requirements. Some individual products contain some sand and gravel. In addition, brown fiber mattresses have brown ropes on the palms and brown ropes on the brown mats.
According to experts, in this comparative test, although the proportion of unqualified mattress materials was not high, one of the 37 spring soft mattress samples was unqualified, and 3 of the 13 brown fiber elastic mattresses were unqualified. However, from the point of view of these unqualified products, it can be said that it is shocking. During the inspection process, it was found that Haishuzhijia, a brand of spring mattress produced by Beijing Haizhilan Furniture Co., Ltd., contained a braided material and stone powder. The interior material of Jianchun brand brown mattress produced by Beijing Ruihongli Furniture Factory is known as straw. The interior of a brown mattress produced by the nominal Jingnan Chunqi Furniture Factory uses straw and fake brown silk.
In this comparative test, in addition to the mattress health and safety indicators, there is also a project with a high failure rate, which is the dry rubbing fastness test.
The tester told reporters that the main purpose of dry rubbing fastness is to detect whether the mattress is discolored. According to the test situation, there are problems with the color fastness of a considerable number of mattress products.
Sun Shudong, director of the Furniture Testing Laboratory of the National Furniture Quality Inspection Center: For the textile testing of the mattress surface, there is also a test index to measure the color fastness of the mattress product. It is to see that this layer of material does not fade, if it fades. This color will be dyed on this sheet, or on your clothes, there will be such a problem. Then we also found in this test that some products have such a phenomenon that the color fastness is unqualified, like this is a test result of our color fastness test. This color card is a national standard color card. Then we compare this sample that has been tested with the national standard color card, and then look at the degree of color loss of this layer of textile. You see this color of this material. It has already appeared on this standard of this fabric, and it should be inferior to the second to third grades like this product.
After testing and testing personnel confirmed that among the 37 spring soft mattress samples, 4 products failed, and the failure rate was 10.8%. Among the 13 pieces of brown fiber elastic mattresses, 3 products were unqualified, and the failure rate was 23.1%.
In a further investigation, the reporter found that an important item with a lower rate of color fastness is durability testing.
Our reporter Wang Wei: What we are seeing now is the durability test of the mattress. This test simulates the human body in the normal use for a long time, and checks whether the mattress is deformed or damaged. The test personnel told us that this indicator It is an important indicator for assessing the service life of mattresses.
Sun Shudong, director of the Furniture Testing Laboratory of the National Furniture Quality Inspection Center: What does this durability mean? It is mainly to measure the person rolling in the mattress during the process of using the brown mattress, which is when rolling back and forth, and then a certain number of times. Under conditions, then measure whether the mattress is qualified. However, in this process of testing, we found that the main problem with this item is that there are two aspects. The first one is the layer of textile on the surface of the mattress, the fabric on the surface of the mattress. When doing this experiment, The surface material is damaged. You see this, this is the surface material of the mattress has been damaged. The second problem is that during the durability process, the brown material inside has ooze out from the textile and the surface of the material.
Testing experts emphasize that durability is an indicator of the life of a mattress. In this comparative test, nine of the 37 spring soft mattress samples failed, and the failure rate was 24.3%. There are 8 products in 13 pieces of brown fiber elastic mattress that are unqualified, and the failure rate is as high as 61.5%.
The amount of formaldehyde released is one of the main testing items in the mattress safety index, and the results of this test are not very optimistic to the experts.
Liu Hailing, director of the indoor laboratory of the National Furniture Quality Inspection Center: The proportion of formaldehyde unqualified is relatively large, and the highest formaldehyde detection data is about 30 times higher than the national standard. Formaldehyde is mainly derived from the original and auxiliary materials of the mattress. For example, the rubber is glued with brown rubber. Then the felt should be glued with glue. If the formaldehyde content of the adhesive exceeds the standard, the formaldehyde of the original auxiliary material is also exceeded, so the formaldehyde of the mattress is caused. Overall exceeded the standard. Formaldehyde is a harmful substance harmful to the human body. The national standards have clear regulations. If the content is too high, it may affect people's health.
According to the requirements of national standards, the formaldehyde emission in mattress products shall not exceed 0.050mg/m2Â·h, and in this comparative test, 2 of the 37 spring soft mattress samples are unqualified in formaldehyde emission, not The pass rate was 5.4%; 6 of the 13 brown fiber elastic mattresses were unqualified in formaldehyde emission, and the unqualified rate was 46.2%.
