View product identification
Whether it is a brown pad, a spring pad or a cotton pad, a genuine mattress will have a clear product name, registered trademark, manufacturing company or address. If the mattress does not have a clear factory name, address and registered trademark, it is likely to be a fake with inferior quality and low price.
Check fabric technology
The fabric of high-quality mattress is quilted neatly without obvious folds, floating lines and jumpers. Press the mattress by hand, there should be no rubbing sound inside, and it feels crisp and comfortable. And inferior mattresses may have inconsistent fabric tightness, floating lines, jumpers and other phenomena.
Observe the internal spring
A good spring mattress uses a moderate number of springs, and the diameter of steel wire should also be considered. Press the surface of the spring mattress. If the spring rings, it means there is something wrong with the quality of the spring.
Pay attention to "black heart cotton"
Beware of "black heart cotton" when buying cotton mattresses. This kind of mattress filled with inferior stuffing is harmful to human health.
