Memory foam has a few one-of-a-kind qualities and is made from visco elastic foam. Sleeping on a full memory foam mattress causes it to conform to the individual's body, but it will then return to its initial shape, hence the name memory foam. NASA first produced it nearly 40 years ago, but as production costs dropped it was made available to the general population in 1991. Ever since it was first introduced it has been very popular.
The memory foam topper was the original product introduced publicly, but it did not take very long before the full memory foam mattress became available. Due to its different qualities it soon became a best seller. As its popularity grew other products were introduced. Today, there are so many different foam products available the buyer can often get bewildered attempting to figure out the type that will be best for them. Additionally, we have the latex mattress which only adds to the confusion. A purchaser must peruse several memory foam and latex mattress reviews to understand the differences.
The majority of the uncertainty with memory foam is due to the large number of firmness levels and densities that are available. Density is the weight of a one-cubic foot section of foam. If a one-cubic foot section is 5 pounds it has a density of 5 pounds. Generally, the denser the foam the longer it will last, but the less soft it will feel.
ILD, short for Indentation Load Deflection, is the way firmness is rated. ILD is the amount of power in pounds it takes to cause a 1 inch indentation in the foam. Measuring ILD is done by taking a 50-inch disc and placing it onto a segment of foam that is 4 inches by 15 inches by 15 inches. The amount in pounds necessary to drive the foam down 1 inch is its ILD rating. In other words, if it takes 14 pounds to compress the foam down one inch its ILD rating is 14. A mattress with a lower-numbered ILD rating is softer.
Lying on a standard spring bed will increase the force on specific body parts such as the shoulders and hips. A memory foam mattress will distribute the body weight of an individual more uniformly and over a larger area. This will slash the percentage of weight in any one area which can result in a more peaceful sleep and decreased back or joint discomfort.
One negative aspect to this style of mattress is its high price. These beds can be expensive. This is why the memory foam mattress topper is so popular, because it is a lot less expensive than a full bed and can be positioned on top of your bed you already own. However, because of their slimness they can wear out faster. If you are unsure about forking over the added money to buy a full memory foam mattress you can get started with the bed topper to see if you like it. If you are impressed with the bed topper you can always take the subsequent step and buy the foam bed.
Memory foam retains heat and is the reason why some consumers do not care for it. If somebody lies down on one of these foam mattresses it will initially feel stiff. Afterward, as soon as the heat from the body is transferred to the foam it will start to become softer, causing it to conform to the curves of the body. The foam underneath the warmth will stay cooler and stiffer, offering good support, while the warm foam will be softer and less stiff, providing more comfort. Many individuals with lower back pain will find that the discomfort goes away after they begin sleeping on a full memory foam mattress.
