How to Determine Quality in a Memory Foam Mattress

When finding the perfect memory foam mattress, the first and foremost thing that should be considered is the actual experience of lying down on the visco mattress. However, there are some problems involved with many unscrupulous memory foam mattress manufacturers’ products such as dips which form after a month or more of usage. Be sure that the mattress manufacturer provides a good warranty along with the mattress to be sure your investment is ‘insured’.

memory foam mattressWe have heard several stories about the ‘valleys’ in a major manufacturer’s visco foam mattress and you can rest assured that we will not be providing much more information on their products, except for a bad review, of course. Currently, Tempurpedic is the standard which we feel is to be compared when considering a high quality memory foam mattress.

Again, when we say a good memory foam mattress, we mean one that cradles your body’s contours providing pressure point relief as well as the amazing comfort that memory foam can provide. A good memory foam mattress will not even require a box spring beneath it to help it do its job. However, a foundation is often used to heighten the bed to the owner’s desired elevation. Once the memory foam mattress is delivered, take advantage of the free sleep trials offered by many manufacturers and see how it feels (considering density, resilience and contouring qualities) to you. This, again, is the most important component, in addition to the warranty offers provided as well, to finding the perfect memory foam mattress which meets and even succeeds your visco foam mattress expectations.

There is so much to be learned about memory foam and the many related products and we recommend speaking with many of the experts such as Memory Foam who focuses on the highest quality offerings and very detailed visco foam mattress information as well as detailed memory foam mattress quality viewpoints and reviews from the perspecive of the manufacturer.

How Grading of Memory Foam is Determined

There are four areas that are covered when grading memory foam. Those four areas are ILD rating, weight, resilience and tensility.

ILD Rating
The ILD rating, or Indentation Load Deflection, determines how firm the memory foam material is. The measurement for ILD ratings is determined through how much, usually in percentage (%), indentation is created through the weight pressure in pounds (Lbs). If an ILD rating is higher then that normally means that the memory foam is much firmer than those with a lower ILD rating.

The amount of chemicals used in the production of the memory foam material and polyurethane foam determined the weight of the foam. Since the chemicals used in the manufacturing process determine the weight, the more chemicals that are used in the visco elastic memory foam production process means a much more visco-elastic mattress.

This measurement determined how ‘bouncy’ the mattress is. When taking resilience in consideration when looking for a memory foam mattress it is important to keep in mind that even though the more resilient mattress is more durable (tested using a steel ball dropped three feet onto memory foam mattress), this would also mean there is more pressure upward towards your body on the mattress. H.R. foam is an example of highly resilient foam.

Tensility of memory foam is the determination of how much the foam can be stretched apart before rupturing. This factor is determined in percentages. However, under most circumstances, memory foam mattresses are not stretched any more that that of the downward pressure of the weight on top of the mattress. So there is little or no need to focus too much on this value when purchasing a memory foam mattress for home use.
