The viscoelastic model is the most technological among the 4 models, because it has hypoallergenic characteristics, sensitivity to body temperature and is able to withstand any height and weight without causing damage to the spine.
With foam developed by NASA, it has as its main characteristic resilience, the ability to return to the original format without deformations. That is, an advantageous option because it molds itself to the body, offering a more adequate support, adapting to its curves without deforming and relieving the points of pressure created when you are lying down. On the other hand, their excessive softness may require that the person make more force to change position during sleep, which can impact the quality of the rest.
Firm or Soft Mattress
The choice of the ideal hip pain at night lying on side mattress should stay in the middle. A good mattress should accompany the natural curvature of the spine and support all areas of the body, providing rest. Those suffering from back pain should opt for a mattress with medium density (neither too hard nor too soft).
Already heavier people should use harder mattresses to ensure better support. If the mattress is too soft, there is a tendency for the body to sink, further increasing the feeling of heat due to poor ventilation. The models with steel springs are comfortable and adapt to the pressure, by both heavy and light people. Now, if there is a significant difference between your weight and that of the person sleeping with you, opt for a system of two bases and individual mattresses, which can be joined with a single sheet-cover. Thus, the unevenness tends to happen with a single mattress and the comfort of both stays.
Test the Mattresses
Do not assume that a mattress is the best because it is firm. To find out if the mattress is comfortable for you, you need to test it. And that does not mean shaking hands, knees, or lying down and getting up immediately.
