Spring mattresses are generally divided into full net springs and independent pocket springs, and better mattresses basically use independent pocket springs.
Left: Full Net Spring Right: Independent Pocket Spring
Bonnier spring
The upper and lower ends have large caliber, the middle diameter is small, and the end faces are knotted and wound. The price of this spring is relatively low in technology and cost. Most low-end markets or some brands will use this kind of spring, but its service life is not short, but it is easy to jam the spring, produce abnormal noise and have poor anti-interference performance.
Clever and gripping
Miaoerkou is the spring water owned by Shudat, which can be regarded as the biggest selling point of their family. Spring is a kind of support of continuous spring, and its structure is Z-shaped, that is, the whole spring net formed by a steel wire from beginning to end. The stability of this spring net will be more stable than Bonnie spring, and it is not easy to collapse, but its anti-interference performance is also poor.
LFK Open Spring (American Spring)
This spring is a quadruple exclusive patented spring and an open spring. Each spring of the open spring will have different opening size and sinking degree according to different pressures, so this kind of spring is more suitable for the body, with good resilience, soft sleep feeling, general anti-interference and easy abnormal sound.
Independent pocket spring
Independent pocket springs are made of non-woven fabrics, and each spring is an independent body and does not interfere with each other. This will lead to higher manufacturing cost, but also better anti-interference. If it is broken, it is more convenient to replace it. Now there are pocket springs with independent zones, which are divided into three zones, seven zones and nine zones, which are more suitable for human parts, but the difference is not great.
The price of the lower net spring mattress is generally around 600-2000, and the cheapest independent bag spring generally starts from 1-2K. Some big brands such as Jin Keer, Yalan, Mu Si and Simmons all adopt this mainstream independent pocket spring.
The life and hardness of the spring are related to the coil itself. A spring mattress with few laps will feel a little difficult to sleep. If it is used for a long time, the pocket spring with fewer turns will wear more, and the service life with fewer turns will be shorter.
