Mattresses can be classified according to different aspects: by the material in which they are manufactured and by the degree of firmness. Taking into account these aspects we can achieve choose a good mattress that suits our needs.
Classification according to the material of manufacture
The material in which a mattress is manufactured is a determining factor that can make us opt for one or the other model. Likewise, the material influences the firmness, ventilation, durability, breathability, etc. The types of materials used in mattresses are: springs, polyurethane foam, viscoelastic and latex. Here we show the characteristics of each of them:
- Spring mattresses
Spring mattresses can be of different types: of independent or bionic springs, of continuous wire spring and bagged spring. Let’s see the characteristics of each of them.
Independent springs (bionic)
They are mattresses whose core is formed by multiple springs of metallic material. These springs are placed vertically, narrowing in their central part. They are also linked to each other by metal wires. These springs produce different subsidence in the different areas of the mattress. On the other hand, the core of independent springs is covered with several layers of different materials such as foam, cotton, etc. These mattresses offer good ventilation and adequate support. They are also quite cheap.
Continuous wire spring
In these mattresses, the core is made from a single wire. Its shape is similar to the bionic spring and like this offers good ventilation. Likewise, the core is also covered by various materials. On the other hand, being made in a single thread, it is a very solid and almost indestructible mattress. It provides a great security in the rest.
The core of the mattress is composed of independent springs, tucked into individual fabric sacks. The springs are joined together by a very fine grip. Since each spring is packed separately, the friction between them is reduced, this provides great comfort. In addition, bed independence is achieved, as with viscoelastic, but without losing breathability, a classic feature of spring mattresses. On the other hand, they offer a good independence of beds.
Often, it has a large coating of different materials, which makes it a mattress halfway between spring mattresses and foam or latex mattresses, including the best features of each one. Also, it offers a great duration and resistance.
- Foam mattresses
They are mattresses that are composed of polyurethane or polyester foam. Its structure is small bubbles of air and is covered by a sheath. The firmness of the mattress will be given by the number of air bubbles per m3, its size and the material used as a cohesive material. The lighter the mattress, it will be softer, less firm and will last less. If the mattress has low densities, i.e. less than 35 kg / m3, it should only be used for occasional beds or for small children whose low weight prevents excessive subsidence. These mattresses are easy to handle and good heat insulators. Its price depends on the density although they are generally economic mattresses.
- Viscoelastic mattresses
Its core is formed by special foam that molds to the body under the effect of heat and pressure. This offers an optimal distribution of body weight. A viscoelastic mattress adapts ergonomically to the body, reducing and relieving pressure points throughout the contact surface.
In addition, these mattresses regulate body temperature, that is, they are sensitive. Likewise, it decreases muscular and nervous tensions; this optimizes blood circulation and improves rest. On the other hand, they are non-deformable and durable mattresses. Another important characteristic of this type of mattresses is that they are hygienic and anti-allergic. Its price is usually higher than independent spring mattresses or foam mattresses.
- Latex mattresses
These mattresses are made with latex, which can be of different types: natural latex or synthetic latex. The natural latex comes from the resin of the rubber tree. Natural latex mattresses have a percentage of this material greater than 85%. If the percentage of natural latex is 100%, it must be expressly indicated on the labels. They are mattresses that adapt naturally and very soft, they are also ecological and breathable. These mattresses are easily available at foam and latex sleep products.
