Memory foam has become such a ubiquitous choice to use in mattresses that it is often difficult for people to choose what is best mattresses for them because of the wide variety of different memory foam mattresses available to them. Perhaps the simplest advice is that the best viscoelastic memory foam mattress for someone is not necessarily the most expensive mattress available. In fact, the particular selection criteria tend to be completely individualistic. However, there are a number of matters which a prospective purchaser might consider:

Density

Perhaps the most important aspect of memory foam that you should consider when purchasing your memory foam mattress if the density of the memory foam. Density of memory foam is typically measured in units of lbs per cubic feet. The density measurement for a typical memory foam mattress will be provided in pounds, the higher the value, the higher the density.

If the density of the viscoelastic memory foam mattress is above five pounds then the memory foam may well be very slow to respond to body is placed upon it. Density is lower than four pounds can mean that the particular memory foam being used does not give the necessary sleeping support and can wear out very quickly.

By deduction therefore, the most frequently recommended density of visco elastic memory foam mattress is between 4lbs and 5lbs.

Indentation force deflection (IFD)

The IFD rating provides purchasers with an idea of how firm or how soft the memory foam used in the mattress is. The IFP rating is perhaps best described as providing information on the feel of the mattress. Obviously, what one person likes in terms of the feel, another person might dislike. The choice depends to be very individual in nature. So the IFP rating usually provides most of the nation if you have previously owned memory foam mattress and particularly liked it.

Thickness

Perhaps the only other significant factor to think about when buying your visco-elastic memory foam mattress is the thickness of the memory foam being used. If you are considering purchasing a memory foam mattress topper, then the recommended thickness is of the order of at least 3 inches. This is widely accepted to provide the best characteristics in terms of support, durability and comfort.
