The production process of Simmons mattress is very complicated. It is not the concept that can be used as a bed when several springs are tied together. To create a beautiful, generous, comfortable and safe mattress alone, it cannot meet the requirements of modern authoritative theories such as ergonomics, mechanics and human sleep science. At present, some manufacturers in the market in the sales process to promote the thicker the better the mattress, this is completely misleading, please do not believe the consumers. The thickness of domestic finished mattresses is generally about 220mm. The thickness of American super-drawing and wire-drawing mattresses is about 250mm. However, some manufacturers' mattresses are blindly pursuing thickness. The production methods and hazards mainly include the following aspects:
First, the super standard increases the number of coils (some increase one or even two). On the surface, the mattress is much thicker, but because the spring is over standard, the life of the mattress is greatly reduced. After the spring has passed 80,000 durability tests. The amount of elastic compression cannot reach the standard (more than 70mm), causing losses to consumers;
Second, the ultra-standard addition of low-density foam, the density of standard filled foam should not be lower than 22kg per cubic meter, because the use of low-density foam will make the mattress collapse quickly after a short time after use, and may even The spring wire pierces the mat surface and hurts the person;
Third, a large amount of waste material is filled, so that the mattress is not technically up to standard, and the mattress is deformed due to excessive or soft mattressing and long-term sleep.
Fourth, if the filling amount is too thick or too much, the breathability of the mattress will be too poor, the bacteria will be easily infected, and the skin disease may be caused by skin hypoxia;
Fifth, the spring exceeds the standard and the mattress is too soft. Some teenagers who are in the growth and development are sleeping and are prone to rickets.
