The memory foam:
The name memory is the most common together with memory foam, in common speech, to indicate memory foam; i.e. viscoelastic polyurethane foam.
For now, let us just remember that it is a thermosensitive and eco-friendly synthetic foam. What these two terms mean, very simple: eco-friendly means that the material, although not natural, is made respecting the environment, without the use of toxic substances and without the release of pollutants. Temperature sensitive means that it reacts to heat, in this way the warmer it becomes, the softer it becomes, the colder it becomes the stiffer it becomes.
However, of good quality which complaints about this problem, concentrated above all in the warmest regions. Does this mean that the memory mattress is not very suitable for those who live by the sea or those who manage to stay short all year long? Absolutely not. In fact, taking the necessary precautions can minimize the problem.
Consequently, a material that reacts to heat is natural that, if not carried out with due care and attention, it can make people perceive an unpleasant feeling of excessive heat. The problem was more frequent with the old types of viscoelastic polyurethane foams. Today it is limited to those of mediocre quality and the cheapest products. Nevertheless, there is still a minority of users of memory mattresses.
The memory that does not heat up:
How can a product that reacts to heat not heat up? There are several solutions. The most used one is that the cellular structure, i.e. the set of particles that make up the polyurethane foam, is open that is able to let the air molecules pass, making the memory foam “breathe”. Another solution is the more spartan one of using perforated memory foam, which increases the effectiveness of the open cellular structure. However, even with these measures, there is a remnant of customers who claim to still perceive the problem.
