Let’s talk about the springs in mattresses. How much do you know about their respective characteristics?

The springs of mattresses mainly include Rastis springs, whole mesh springs, independent pocket springs, partitioned springs, and open springs. Let’s talk about their characteristics separately:

Lastis spring is a kind of interlocking integral spring. It is a continuous spring group penetrated by a steel wire. It is the product of mass production of spring bed core. .

Structure: It is a continuously wound three-dimensional steel wire body, linked by spring steel wires.

Advantages: high production efficiency, greatly reduced steel wire costs, and good overall elasticity of the spring.

Disadvantages: The springs interfere strongly with each other, and the steel wires are prone to making noise when they are wound around each other.

The whole network spring

Difference from independent spring, a single spring is expanded into one piece to become a surface and a whole. The whole network spring system affects the whole body. If one place is pressed, the nearby springs will pull each other.

Disadvantages: When turning over in sleep, one side turns, which directly causes the other side to shake, which has a greater impact on the partner who is sharing the bed.

Independent pocket spring (Marshall spring)

The spring of choice for international high-end mattresses is currently the most representative spring bed core. Each individual spring is free to rebound according to the pressure it carries, without any involvement from the other.

Structure: It is composed of open single springs placed in cloth bags and connected, and the rigid connection is converted into a flexible connection.

Advantages: Point-like telescopic, single independent support, overall fit the body curve, effectively support various parts of the body, disperse pressure; anti-interference, silent, does not affect your partner's sleep.

Disadvantages: Frequent pressure on a certain part of the mattress will cause local loss of elasticity.

Zonal springs

Fifth-degree zoning springs generally use independent pocket springs or LFK open springs. According to ergonomics, they are designed for the head, shoulders, back, waist and legs of the human body. Designed according to the stress conditions of each zone, it provides support with different softness and hardness, fully fits the human body curve, effectively responds to various body movements during sleep, and ensures healthy spine stretch and smooth blood circulation.

In addition to the five-degree partitions, there are also three-partitions and seven-partitions.

The three-zone mattress is mainly for the head, shoulders, back, waist, hips and legs. The waist and hips are a whole. No matter whether it is too hard or too soft, the waist will never get strong support; the seven-zone mattress is based on ergonomics. From a scientific point of view, too fine a division is redundant, and because of the increased manufacturing cost, the price of the mattress will be higher.

Relatively speaking, the five-zone spring is more delicate and scientific, and can meet the different softness and hardness requirements of the bed core in different parts of the body.

Open spring

Its birth marks that bed core manufacturing has more humanized functions.

Structure: An open single spring group connected by a spring steel wire. Since the single spring ring is open, although the connection method is still a spring steel wire connection, the elastic freedom of the single spring is greatly improved. increased.

Advantages: A single spring has good vibration, better elasticity, better sensitivity to load, and fits the human body curve well; eliminates human body pressure, improves comfort, and has certain anti-interference sex.

Among the open springs, the LFK open spring is a newly developed super-elastic spring with the characteristics of never sinking, super lightness, and super elasticity. The uniform spring diameter and uniform spring waist diameter provide a more stable supporting force, and every part of the bed net surface can better bend in accordance with the curves of the human body.
