- SuperLastic Spring : This kind of spring should be the type we have had the most contact with . It is simple in processing technology, cheap in cost, relatively soft, and has a short lifespan. It will make a creaking sound when sleeping, which is common in the low-end market and is currently basically eliminated.
2. Bonnell spring is a round spring with a whole network, with simple process and low production cost; its spring is characterized by large two ends and small middle, strong support and sufficient elasticity; but there will be abnormal noise and circlip, and the anti-interference performance is poor; Common in the low-end market.
3. LFK Spring (exclusive to Sealy), the industry name is LFK open spring, the process is complex and the cost is high; its characteristic is that the openings at both ends of the spring are not closed, so that the size of the opening can be changed according to the pressure degree of depression; the fit of the human body is high and the comfort is strong. Soft sleep, no circlip, and weak anti-interference, it is used in the high-end market.
4. Mira Coil springs, exclusive to Serta, complicated in process and high in cost; if a steel wire goes to the end, the four points are in a double “Z” shape, the structure is stable, the support is strong, there will be no circlip phenomenon, and the sleep feeling is hard , poor interference, common in the high-end market.
The Individual Pokcet Spring for Mattress :
the first independent pocket spring mattress was first invented by vispring; At first, Simmons invented the machine for producing independent pocket springs, and began to mass-produce independent pocket springs, only because Simmons’ patent protection period expired; Some advantages of springs, individual pocket springs are becoming popular.
Each spring of the independent pocket spring is individually bagged with cloth, and then glued or ultrasonically sealed. The springs are “independent” one by one, so they have strong anti-interference and high degree of fit.It can bear the pressure of all parts of the body evenly, so that the body will not be sore because of being suspended. The bag outside the independent pocket spring is also more particular. Generally, the better ones will be assembled with non-woven fabrics, and the better ones will be made of DuPont cloth. The quality of this DuPont cloth will be better and not easy to tear.
