Full Memory Foam Mattress

Memory foam has several unique properties and is made from viscoelastic foam. When lying on a mattress made of full memory foam, the mattress adapts to the shape of the body but then returns to its original shape, hence the term memory foam. NASA first produced it about 40 years ago, but as production prices fell, it became available to the general population in the early 1990s. Since then it has enjoyed great popularity.

The shape memory foam mattress topper was the first product to be offered to the public, but it wasn’t long before the full memory foam mattress was selling like hot cakes. Because of its uniqueness it became a best-selling product. As sales increased, other products were created and marketed. Today there are so many other foam products that the buyer can easily get confused when trying to decide which one might be best for him. We also have the latex mattress, which makes it even more difficult to make a decision. A buyer has to read several reviews of foam and latex mattresses to learn about the many differences.

Most of the confusion with foam is due to the large number of degrees of hardness and densities available on the market. The density is the weight of a 1-cubic foot part made of memory foam. If a 1-cubic foot part weighs 5 pounds, it has a density of 5 pounds. If the foam is denser, it usually lasts longer, but doesn’t feel as soft.

Hardness is expressed as an ILD value. ILD stands for Indentation Load Deflection and is the force, calculated in pounds, required to create a 1 inch indentation in the foam. Indentation load deflection is measured by taking a 50-inch disc and placing it on a piece of foam measured at 4 by 15 by 15 inches. The amount of weight in pounds required to push the foam down 1 inch is its ILD value. If 14 pounds are required to push the foam down one inch, its ILD rating or ILD value is 14. Bedding items that have a lower ILD rating or score will be more dented.

Snoozing on a standard duvet increases the pressure on certain areas such as hips or shoulders. A foam mattress distributes a person’s weight more evenly and over a larger area. This reduces the pressure in a certain area, which can lead to a calmer siesta and less joint pain.

One of the disadvantages of a memory foam mattress is the cost. The prices for this type of bed can be quite expensive. This is why the shape memory foam mattress topper is so popular, because it is much cheaper than a full-size bed and can be placed on top of your existing bed. Nevertheless, because they are slim, they usually wear out more quickly. If you are not sure whether you should spend the extra money to buy a full memory foam mattress, you can start with the mattress topper to see if you like it. If you are impressed with the mattress topper, you can always take the next step and buy the foam mattress.

Memory foam stores heat and is the reason why many people do not like it. When someone lies on a foam mattress, it feels stiff at first. Later, when the person’s warmth is transferred to the memory foam, it will start to soften, adapting to the curves of the body. The foam underneath the warmth stays cooler and less soft, providing more support, while the warmer foam is softer and offers more comfort. A large number of people with lower back pain will find that their complaints disappear after they start to doze on a foam mattress with full memory.
