Independent springs - These are springs that are not fastened together and are in individual bags.
An invention that has been providing convenience and comfort for over a hundred years. Mattresses with a similar design are popular all over the world and are universally recommended as one of the most effective technologies for healthy sleep.
The use of from 300 to 1 thousand springs per square meter in such mattresses provides them with high orthopedic qualities. As a rule, the life of such mattresses is from 10 years.
Differences between independent and dependent springs
Unlike traditional mattresses, the technology of independent springs does not allow “failure” of individual sections, since each built-in spring is not connected to the others, and even under pressure does not pull them along.
Unlike the old Bonnel system, in which all springs are connected directly, the connection between the springs is made using special covers. Due to this, an orthopedic effect is achieved - the surface of the mattress optimally adapts to the owner and evenly distributes the load on the spine.
Reference:Mattresses with the most independent springs also use the best materials for production, such as coconut coir or latex. This affects the total cost, but pays off for their quality, convenience and durability.
What are independent springs
There are various types of independent spring blocks used in the manufacture of mattresses. The main differences are in the number of turns, the diameter and density of the sections per square meter. The higher these indicators, the stronger the anatomical effect.
Contains up to 500 springs per square meter 7-10 turns long. Provides high orthopedic properties and comfortable use. Ideal for people of medium build.
One of the most popular blocks, distinguished by its budget, but at the same time slightly inferior to peers in orthopedic terms. There are various modifications that differ in the density of the mattress. For their manufacture, blocks are used in 256, 310 and 510 springs per square meter.
Spring in spring
Ideal for large people, also ideal for couples with a significant difference in weight. The orthopedic effect is achieved through the use of smaller auxiliary springs in the blocks, alternating with the main ones in a checkerboard pattern and distributing the load depending on severity.
One of the latest manufacturing technologies that allows you to create point stiffness sectors in each individual block. Contains up to 256 springs per square meter mfor the manufacture of which wire of various lengths is used. Due to this, the effect of relieving muscle fatigue and stress on the spine is achieved.
A distinctive feature of such blocks is increased stability and strictly vertical compression of the springs, which occurs in three stages. The presence of several degrees of rigidity provides additional comfort when using mattresses of this system.
Multi-zone spring blocks
These mattresses use additional reinforcement in the form of 5-7 cross blockslocated in areas with maximum load. The use of springs of increased stiffness avoids punching and significantly improves support for the spine.
When independent springs were invented
The first mattresses with blocks of independent springs were released in 1900, but they had a high cost associated with manual manufacturing technology. Because of this, they were not in high demand among the population. Only 25 years later, the British company Simmons registered a patent for machine production, which allowed to reduce the retail price and make products affordable.
In the manufacture of independent spring units, each spring is placed in a separate, closed case. Then the cells are fastened together. Such technology is characterized by noiselessness and the absence of a "wave" effect, characteristic of classic spring mattresses.
