What are the types of mattresses?

 

Memory foam

Memory foam mattress

One of the best features of the California king memory foam mattress is it is built of HR foam (High Resilience Foam) that perfectly adjusts to the shape of the body, reacting to its warmth. The effect of the foam is less pressure on the muscles and blood vessels during sleep, also recommended for two people of different weights. Modern material engineering has allowed us to combine all the advantages of latex and high-flexible foam in one hybrid. This material is called hydro latex. Read how to clean memory foam mattress.

We love:

  • Lower price than a good latex mattress
  • A mattress is better suited to the anatomical curves of the body than a latex mattress thanks to the foam, which has endless support points
  • If the mattress is selected correctly, it ensures good sleeping comfort
  • It breathes very well in comparison with latex
  • In more advanced models there are quite a lot of additions of natural castor oil and vegetable oils
  • Very high resistance to deformation and tearing in high-quality foams

 

Gel

Gel mattress

This mattress has interesting properties. During hot days it lowers the temperature of our body allowing us to fall asleep better. It has a very high thermal capacity and therefore maintains a constant sleeping temperature all night long. Even if we leave the bed, when we return in 15 minutes, the temperature will still be the same. The gel itself is by far the best to reduce tensions and tensions among all available materials used in the production of mattresses. It is the same gel that is used to make marathon running shoes.

For whom?

First of all, for people who like thermoelastic mattresses and are too warm on them, and for those who appreciate a constant sleeping temperature. This material is a sales hit in the countries of southern Europe. Not only because of the lowering of the sleeping temperature but also because of the unbelievable possibilities of relieving the muscles and joints.

 

Innerspring

Spring mattresses are the most popular group of mattresses on the market. They are made of various types of springs: Bonell, pocket, or multi-pocket. Each of these types differs from the other in terms of perceived comfort, quality, or price. It is this diversity that makes the spring mattresses meet the needs of so many different users.

Innerspring mattress

The pocket mattress is made of independent springs embedded in special material pockets. Each spring works almost independently. Another difference between a Bonnell spring and a pocket spring is the thickness of the wire. In pocket springs there is usually thin wire. In this type of mattress, there is point elasticity, which makes the phenomenon of wavy mattress very limited. The more springs in the mattress, the more support points working.

Pocket mattresses are a guarantee of a comfortable and long life. The advantages listed below make this group of mattresses the most popular on the Polish market. Springs placed in canvas pockets allowing them to work independently are the contribution of this mattress. Such a solution allows obtaining many support points on its surface and makes it fit perfectly to the body. Depending on the model, the springs of different diameters are used. The calsmaller the diameter, the more springs in the mattress and thus better support for the body. The pocket insert is lined on both sides with plates made of various types of foam, whose task is to prevent it from direct contact with the body. In various models, it can be polyurethane foam, highly elastic, or the best designs of thermoelastic or latex foam.

We love:

  • With the right mattress, a good price/quality ratio
  • Better fit of the mattress to the anatomical curves of the body than in a bonellow mattress
  • If the mattress is properly selected, it provides a basic comfort of sleeping
  • It breathes very well
  • A well-chosen mattress will ensure that the spine is in the right position

To consider:

  • The mattress is difficult to maintain hygiene – not recommended for allergy sufferers
  • Lower life expectancy
  • Low warranty on the mattress insert
  • Attracts electromagnetic waves TV, Radio, Internet, GSM, because it works like one big antenna
  • It often forces changes of position due to springs that spring and exerts pressure on the body
