Tips for choosing your memory foam mattress
First, you need to know what you need, this will help you choose the right mattress for you. Here are some key questions to ask before buying a memory foam mattress.
1) What is the density of the foam?
Whatever you think, density has nothing to do with the feeling has to touch the foam, but rather shows its durability. A mattress with a density of 5 pounds per ft3 will last much longer than a mattress with a density of 3 pounds per ft3. This is why companies can offer guarantees over 20 years.
Most high-end mattresses, including Tempur have a density of 5 to 5.4 pounds per ft3. Essentia mattresses density is 6.25 pounds per pied32.
Coming up: Several brands of mattresses use of poor quality foam with a density of 5 pounds per ft3 in the upper layer of the mattress (1 inch from the surface) and then use the foam with a density of 2 or 3 books in the underlying layers.
2) What is mmHg?
The mmHg is the unit of measurement that describes the reaction of the mattress to pressure. It is difficult to provide a mattress with a bottom mmHg. The higher the mmHg, the greater the blood flow is difficult. According to health experts, and less than 32 mmHg are values that can mitigate the weight pressure points.
Essentia mattresses offer 12.43 mmHg to 200 pounds, which is the best rate of the industry.
3) What is the indentation hardness (ILD) of the foam?
The value of the indentation hardness ranges from 6 to 40. The majority of mattresses on the market have a value of indentation hardness between 10 and 16.
Several types of memory foam mattresses are made up of several layers that have different mmHg to maximize comfort. The mattresses made up of several layers of foam having different ILD are usually better, because it ensures that the mattress layers interact.
4) Where the mattress has made?
Many companies claim that their mattresses are manufactured in the United States or Canada. They can legally claim as their mattresses are actually assembled in one of these countries. However, they import some or all components from other country.
Why is it important to know the source of a mattress? It is very rare that mattresses are tested when they enter the country, so it is impossible to know what chemicals were used. These products are often mixed together and we can not know the ingredients used. Some products still in use have been linked to cancer, lung disease and can have negative effects on the developing central nervous system and brain.
