Full Memory Foam Mattress – Is It The Ultimate Bed?

Memory foam is produced from visco elastic polyurethane foam and has some distinct traits. Lying on a full memory foam mattress will cause it to conform to the body, but it will then return to its initial form, hence the designation memory foam. It was originally produced for NASA in the 1970s, but as production prices dropped it was made available to the public in the 1990s. Since it first became available it has been very popular.

The memory foam mattress topper was the very first product offered publicly, but it did not take very long before the full memory foam mattress was selling like hotcakes as well. Due to its unique character it quickly became a best selling product. As sales continued to climb additional products were produced. Today, there are so many other foam products available to purchase the customer can very easily get confused trying to determine the type that might be perfect for them. We also have the latex mattress which only adds to the confusion. A shopper has to read several memory foam and latex mattress reviews to get an idea of the dissimilarities.

A large amount of the bewilderment with memory foam is due to the many densities and levels of firmness that are for sale. Density is the weight in pounds of a 1 cubic foot piece of foam. If a 1 cubic foot piece is 5 pounds it has a density of 5 pounds. Generally, if the foam is denser it will last longer, but it will not feel as soft.

ILD, also called Indentation Load Deflection, is the way firmness is rated. ILD is the amount of power necessary, calculated in pounds, to bring about a 1 inch indentation in the foam. Measuring ILD is done by taking a 50-inch disc and placing it on top of a piece of foam that is measured at 4 by 15 by 15 inches. The amount of weight in pounds it takes to force the foam down a single inch is its ILD rating. If it requires 14 pounds of load to compress the foam down an inch its ILD rating or score is 14. Bedding that has a lower-numbered ILD rating or score is softer and will indent more.

Lying on a regular spring mattress will cause an increase in the amount of force on specific points such as the hips or shoulders. A memory foam mattress will spread the weight of a person more evenly and over a greater area. This will lessen the percentage of weight in any one area which can lead to a more restful siesta and decreased joint or back discomfort.

One negative aspect to this type of mattress is the price. The selling prices of these kinds of beds can be relatively expensive. This is one reason why the mattress topper is so popular, because it is a great deal less expensive than a full-sized mattress and can be placed on top of the bed you already own. However, because of their thinness they can wear out quicker. If you are not sure about shelling out the extra cash to purchase a full memory foam mattress you can initially start with the bed topper to see if it agrees with you. If you like the feel of the bed topper you can then take the next step and purchase the foam bed.

Memory foam retains heat and is why many individuals do not want it. When someone lies on a foam bed it will in the beginning feel stiff. Later, when the body heat transfers to the foam it will start to soften, which will cause it to conform to the person's body contour. The area below the heat will remain cooler and less soft, offering great support, while the warm area will be softer and less stiff, providing more comfort. A large number of individuals with lower back pain will find that their discomfort disappears due to sleeping on a full memory foam mattress.
