The density of the viscoelastic material in memory foam mattresses results in the amount of material it contains per cubic meter. Depending on the density of the viscoelastic used for the manufacture of memory foam mattresses, these will offer some benefits or others.
It could be said that at higher density in memory foam mattresses means greater viscoelastic sensation and greater degree of adaptability, therefore, you have better results. However, there are those who opt for an average adaptability and density.
- The lowest density that can be found in viscoelastic cores oscillates around 18-20 kg/m3.
- We could speak of an average density in memory foam mattresses when it comes to viscoelastic of 30-40 kg/m3
- A high density is when it exceeds 50 kg/m3.
The performances and densities of this memory foam mattress material are usually certified by independent institutes and laboratories. It is important that a mattress have available certificates that guarantee about the product quality and component materials.
Composition of a Memory Foam Mattress
The parts that make up a viscoelastic memory foam mattress are mainly four as the sheath, the padding, the viscoelastic core and the high resilience foam backing. However, the market is very fragmented and you get the basic products that do not have all these elements, which makes the price of the memory foam mattresses vary depending on whether it is the most basic or the highest range. It is important that the memory foam mattress manufacturer specifies the parts of which his product is composed of and that the consumers who request these specifications or can be found with a memory foam mattresses without the structure necessary for its durability.
The memory foam mattresses cover can be fixed or removable. The characteristics will depend on the range to which it belongs. In high-end memory foam mattresses, the covers include added features such as a topper with more viscoelastic material and specific ventilation systems to increase comfort. There are covers with advanced aeration concepts, which make the mattress an important part of the mattress for applying concepts such as continuous ventilation of the core, thermoregulation, hygienic barriers to the proliferation of bacteria, dust mites, and avoid any accumulation of moisture. In addition, these memory foam mattresses covers can include padding and special materials that are included in their manufacture and provide a comfort to the core.
The padding of viscoelastic memory foam mattress is between 1cm and 10 cm, depending on the range and manufacturer, regardless of the density containing the viscoelastic mattress core.
The support on which rests the viscoelastic core is a foam generally called HR (High Resilience) and provides end firmness to the mattress, something like the foundation of the mattress. There are different types of RH and different characteristics. As with viscoelastic material, these foams can vary in density, being the usual 30-40 kg / m 3 and are higher than these in high-end mattresses.
