Memory Foam Mattress - History

By Edited Sep 2, 2015 0 0

Memory foam began to take center stage in the 70s as the National Aeronautics and Space Administration, or NASA, started experiencing with a substance that would reduce the impact of the g-forces that astronauts had to deal with at lift off. Memory foam, which is also called visco elastic foam, was, at that time, only found in hospital beds. Now, you can get it in the form of pillows, mattress pads, and mattresses.

Memory foam gently conforms to the sleeper's body shape, and automatically adjusts based on the sleeper's weight. The mattress absorbs the sleeper's body weight evenly, which reduces pressure points. After the sleeper gets out of bed, the memory foam returns to its previous condition.

There are several factors that go into grading memory foam. These are: tensile, Indentation Load Deflection or ILD, and resilience. Weight is determined by the density in lbs/square foot. The number of chemical elements in foam is what decides the foam's weight. If there is a high number of chemical elements in the foam, it is considered to be more visco elastic. The ILD grade tells buyers the softness or hardness of the foam. If a mattress has a high ILD grade, then it is going to be on the harder side. Resilience is an indication of the amount of spring in the foam. Tensile is an expression of how far the foam can be pulled prior to ripping. These measurements should be taken into consideration to make sure the product is of high quality and meets the standard of a memory foam item prior to buying it.

Superior memory foam items are going to be more expensive than those that are not. If you were to get a memory foam mattress pad, you will save some money over buying a full mattress, and it does the same thing. Memory foam pillows are designed to properly align the neck and head, and will be cheaper than either mattresses or mattress pads. You should be able to find high-end memory foam pillows at a discount.

The selection of a superior single memory foam mattress is essential. If you get a mattress that is not made as well or is made of inferior materials, you will not receive the comfort you desire. You should always perform adequate research on the grading, cost, and makers of memory foam products prior to buying a product.

Certain companies or stores might ship out samples of their memory foam products to potential customers who make such a request. Customers will want to examine a variety of companies.

You might find it best to shell out a little more money for a better product. Paying less for a product won't be worth the money you save if you have to buy a new one too soon.

Customers who do their homework on memory foam products are going to end up with a great item at a reasonable price.
