Production label
Authentic mattresses, whether brown, spring or cotton, are marked with product name, registered trademark, name and address of manufacturing company or factory, contact number or fax, and some are equipped with qualification certificates and credit cards.
Fabric technology
In addition to cotton pads, brown mattresses and spring mattresses have beautiful mattress fabrics. The quilting tightness of high-quality fabrics is consistent, and there are no obvious folds, floating lines and jumpers; The four corners of the seam are symmetrical, without burrs, and the floss is straight.
Internal material
The number of springs used in the spring mattress and the diameter of steel wire determine the softness, hardness and moderation of the spring mattress. Press the surface of the spring mattress by hand. If the spring rings, it means there is a quality problem with the spring. If it is found that the spring is rusted and the lining material is shabby sacks or flocculent fiber products made of industrial leftovers, then the spring soft mattress is definitely inferior.
Cotton mattress
"Black heart cotton" is another name for inferior floc. The "black heart cotton" mattress is made of waste fiber products such as fibrous industrial leftovers, medical fibrous waste, regenerated fibrous substances, and waste clothes.
