Simmons, latex pads, brown mattresses, and many mattresses that have been popular in these years, but the quality is really good? Recently, the Nanjing Municipal Quality Supervision Bureau issued a sample inspection report on the quality of mattress products. The pass rate is 70%. Among them, the problem of excessive formaldehyde emission is more prominent. The formaldehyde emission of brand products such as “co-creation†and “Roman Diou†exceeds the national standard by more than seven times.
Do you think that the mat is more environmentally friendly? This sampling shows: not necessarily!
Everyone thinks that the brown mattress is more environmentally friendly. Indeed, the brown palm and the shredded coconut are indeed no problem. The problem is the adhesive. "Adhesive materials, low-melting fiber glue and chemical glue. The price of fiber glue is high, chemical glue is cheap but there is formaldehyde." Zhao Yingfeng, panel furniture technology engineer of National Building Materials Quality Supervision and Inspection Center of Nanjing Quality Inspection Institute, said. Some small business small workshops use recycled inferior brown sheets and then bond them with a large amount of chemical glue. These products often have serious formaldehyde standards.
If the coir mattress is made of viscose, it will have a white layer and it will be elastic when pressed. "It has a low formaldehyde content and relatively low physical properties. It is easy to pull open when pulled." If you use chemical glue, it will be very hard to touch, but the formaldehyde content is very high.
Because the mattress has the longest contact time with people, the contact distance is also the closest, and the national standard for formaldehyde emission is very high. In this test, there were 5 batches of unqualified formaldehyde emission, which were all mattresses with mats. It is reported that long-term exposure to such mattresses, the nervous system, immune system, liver, etc. may be poisoned.
The mattress spring is so comfortable? The accessories are not closed, not necessarily!
In addition to the core spring or mat, the mattress has a layer of bedding. Such as felt, foam sponge, textile fabrics, etc. Zhao Yingfeng introduced that the combination of different material bedding materials can play a good role in absorbing pressure and distributing conduction pressure, so that everyone can sleep more comfortable. However, if the configuration and the sewing process are not in place, the mattress will be felt to be damaged, which will seriously affect the comfort. “The high-quality foam has a high density and good elasticity. It can also be supported by people rolling on and off. However, the inferior foam has a small density and a large gap. It is easy to sag when sleeping for a long time, causing the mattress to be uneven and sleeping on it. Uncomfortable," said Zhao Yingfeng. The sampling rate of this project is only 61.9%, and the data of brands such as “Hippo Deduction†and “Meiyu Gao†are only about half of the standard requirements.
A good mattress can be done once and for all, and when it is over, it is time to retire!
Gao Yanping, Department of Orthopaedics, Guangdong Provincial People's Hospital: Many things have been used for a long time, and there are feelings, especially for some old people, but some things have to be replaced after a long time, such as mattresses.
Like a spring mattress that is used more now, if the spring loses its elasticity, the bearing force will be affected, and then it will not be used to maintain the normal physiological curvature of the human spine. Especially for the elderly, falling asleep at night, the muscles are not evenly stressed, because the muscles of the elderly are poorly elastic, there will be a feeling of pain and easy to wake up. In general, mattress springs of 8 to 10 years have entered a recession, and even the best mattresses should be "retired" in 15 years.
