April sweet sleep, says an old ease, but on which mattress? How to evaluate the mattress we have at home and how to choose a new one if ours is outdated? What is the right mattress? Let’s clarify a variegated world where models, materials and prices are the most varied. First of all it must be said that if your mattress is more than 10 years old it is time to change it! A new mattress improves the quality of the night and the quality of the days because it allows you to wake up well rested and with so much energy, not to mention that it allows you to live better in a healthier and longer way.

The mattress is the first component of the bed system, built in latex or in more modern materials such as pocket springs or water-foamed and memory springs, able to adapt perfectly to the natural shapes of the body, aligning legs, pelvis, back, neck and head , for an ideal posture during the night. Let’s look briefly at the individual materials.

Biconical springs are traditionally the material that has replaced wool and horsehair. Their number in a mattress can vary, determining the quality: the higher the number of springs, the more the mattress will be able to follow the natural curves of the body of the person who lies down. With the evolution of the technique the number of springs has increased in exponential numbers, they are no longer connected to each other with a thread but with bags, hence the name of “pocket springs”, obtaining an independence, a resilience and a ergonomics of the spring mattress that could not be reached with the traditional technique.

The latex foam mattress is a product obtained from the processing of rubber, a natural rubber extracted from Hevea Brasiliensis, also known as “rubber tree”, a plant native to the Amazon and now widespread in tropical Asian forests, in Malaysia and Sri Lanka in particular.

The polyurethane for mattresses, in the past also called “foam rubber”, has seen in the last decades the introduction of water as a blowing agent, thus obtaining even more flexible materials: the so-called water- based foam. The elasticity of foamed mattresses is very high, so as to present ergonomic features that allow them to model themselves and follow the physiological curves of the body. In its more thickened version, able to compress and return to its original state, it is called “shape memory foam” or memory foam. The characteristic of welcoming – unlike the other materials, which push it – make it antidecubitus, that is optimal for hygienic-sanitary applications and particularly performing to be used in the seats of space vehicles and the beds of space stations to make astronauts sleep.

In general it is important that the mattress meets the requirement of not hard, not soft, but ergonomic, that is soft on the surface – where the shapes of the relaxed body are received and followed – and compact centrally to support the weight and the curves of the body. The mattress is one of the elements of the bed system together with the bed base and the pillow; which we will see next month.

RISPONDO a Luisa da Scaltenigo che mi chiede come scegliere il materasso giusto per tutta la famiglia?

In base alla tipologia di materiale di cui è fatto il materasso giusto per te è quello in lattice naturale, con un sostegno di spinta elastica, se ti piace essere “accolta” dal materasso, ami i prodotti naturali e il tuo peso non è eccessivo; quello in memory foam/schiumato poliuretanico, se ami i materiali moderni e tecnicamente performanti, con un elevato accoglimento e un avvolgimento grazie al materiale viscoelastico memory; infine quello a molle insacchettate/molle tradizionali se ami un prodotto che ti sostiene con la spinta della molla. In qualsiasi caso il consiglio è di andare a provarlo, meglio se in fabbrica dove vengono costruiti e ci sono persone con esperienza che ti possono aiutare nella scelta.
