In fact, the springs of spring mattress can be divided into two categories: independent bagged springs and whole net springs. The types of mattress springs are as follows:
1. Independent bagged spring, scientific name is Marshall coils (named after the inventor). Each spring is packaged in an independent cloth bag and assembled into a bed net through the connection of the cloth bag. Its greatest feature is the point like stress distribution, single independent support, and good anti-interference performance, which is incomparable to other springs. Due to the point force, the whole body fits the natural curve of the human body and effectively supports all parts of the body.2. Offset coils, its biggest feature is that the two ends of the spring are designed with openings, the end face is not knotted, and the vibration of a single spring is good. The opening of the spring will change according to the pressure, which can also fit the human body better. The open spring is matched with the string spring to form the whole net, which is much better than the independent bagged spring.
3. Continuous coils, the biggest feature is that a steel wire goes to the end, but there are different wiring methods. Its anti-jamming performance is the worst. It may affect the sleep quality of people around you because it is very quiet when turning over and getting up at night.
4. Bonnell coils, Bonnier spring technology appeared earlier. A single spring is a conical spring core structure, with two ends large and middle small, connected by a series spring (spiral lock). The resilience is good and the force balance is good.
