Buying a mattress today becomes a very complicated task, given the number of materials that exist in the market and used for the manufacture of mattresses.
The interior of the mattress or core is made with iron wires fixed at the top and bottom to a steel contour rod; then on this core of quilts of fabrics and foams are placed, giving multiple final results. There are also several ways to arrange the springs:
Continuous thread: It is made with iron wire that goes through the structure in a zigzag pattern. Its result is a very firm and resistant type of product.
Bionic springs: They are biconical springs and coupled by a rod in the contour. It is the traditional spring system and its main feature is a high firmness.
Cylindrical or bagged springs: The springs, as its name suggests, are cylinder-shaped and wrapped in cloth sacks, to avoid friction. They are independent structures, provide precise support to the body and when there is no friction between springs; they are quieter than the previous types.
The latex comes from the sap of the tropical tree “Heveas Brasiliensis”, cultivated in Asia, Africa, and South America. Most of this resin is used for the manufacture of surgical gloves, tires, and condoms; the other part is dedicated to the rest industry. In the manufacturing process, the resin undergoes a vulcanization process, which gives rise to a block of elastic foam, athermic, hygienic and that varies in thickness. The latex gives the possibility of combining different firmness in its surface, thanks to the perforations in the core, and then we would get different rest areas for the different areas of the body.
The viscoelastic is a form of the last generation, which initially was used exclusively for therapeutic use, for people who had long periods of convalescence. The reason was that the main characteristics of the material: the thermosensitivity and the reaction to pressure; coupled to the body curves of the sleepers, creating a perfect mold.
We can find combinations of this material with others, but the most frequent is the one that uses as a support a layer of polyurethane foam of high resilience (or “high resilience”). As detailed with the previous materials, the final result may vary depending on the thickness of each layer, the type of viscoelastic material used, the composition of the polyurethane foam … etc.
