Memory Foam Buyer’s Guide for the Newcomer

This article is about memory foam bedding products. It addresses all of the most frequent questions and concepts that people have while researching for new bedding items.

In 1966, memory foam was developed by NASA's Ames Research Center in an effort to improve aircraft safety. Led by Chiharu Kubokawa and Charles A. Yost, the project was originally named "temper foam." Over the next 20 years, the material was used only in the medical industry as a way to alleviate pressure sores. The cell structure of memory foam reduced pressure points by allowing pressure to distribute more evenly throughout foam cells. In the early 1990's, Tempur-Pedic became the first company to introduce memory foam to consumers. Tempur-Pedic is still regarded one of the premiere distributors, however several other companies have emerged within the marketplace since that time - particularly online.

What is memory foam? This is a type of foam material that reacts to your body heat allowing it to contour around you in only a couple of minutes. It is used in the bedding industry, particularly people who are looking for a more comfortable sleeping experience. Memory foam has proven to be quite helpful for people suffering from Insomnia, Arthritis, and chronic back pain. It is also known as "visco-elastic polyurethane foam" and "low resilience polyurethane foam." In terms of price, these mattresses usually cost more than traditional mattress models.

There are many benefits to memory foam products. They can reduce pressure points considerably, provide quality and "deeper" sleep, as well as prevent you from tossing and turning at night. Typically, these type of mattresses are denser than other foam mattresses. One downfall of it is that it is generally heavier than other materials, however the support is unparalleled. People that are looking for a nice compromise between a soft and firm mattress may find memory foam mattresses to be the most appealing on the marketplace because of these benefits.

High-quality and luxury memory foam typically has a density in excess of 4lbs. Some manufacturers have recently introduced memory foam in excess of 7lbs. Some people prefer a density within the range of 4-5 lbs, whereas others tend to like densities up to 8 lbs. However, you should generally stay away from memory foam that has a density of less than 3 or 4 lbs. This is typically low-quality foam that wasn't manufactured within the United States.

Important - Some manufacturers located in 3rd world Asian countries have used clay particles to increase the density of these products. When you are looking for a new product, be sure to research where the product was manufactured as these clay particles can have a detrimental impact on the longevity of the item. You don't want anything that is compromised in value. Always check reviews and ratings to ensure you are looking at a quality product.

If you are in the market for a memory foam topper, chances are you have a firm mattress already and need that extra "oomph" to soften it up. Toppers can range between 2-4 inches depending on the brand. If your mattress is already soft and you prefer something firmer, a topper may or may not be beneficial, although it is not recommended, as the foam is by default softer than most other materials. You may be better off getting a whole new mattress entirely if this is the case. If your mattress sleeps two, I recommend using a topper between 3-4 inches in thickness.

In measuring firmness, there is a rating known as the "IFD" which stands for Indentation Force Deflection. IFD measures pounds-force required to make a dent one inch into a foam sample. They can range from "super-soft" (IFD 10 rating) to semi-rigid (IFD 12). Most firm foam mattresses range between 12 and 16. It isn't necessarily the "end-all, be-all" measure of firmness, but it's a good indicator in conjunction with the product's density. For example, a higher-IFD rating with a low density can still feel soft when compressed.

One thing to strongly consider when choosing memory foam: A number of memory foam brands provide free trials, warranties, and money back guarantees. Free trials are usually between one month and several months. Higher quality memory foam brands generally provide at least a 20-year warranty. If you are looking at a brand that doesn't provide any of the aforementioned "perks," you are probably better off looking elsewhere. You don't want to be stuck with a mattress that you do not like.

Often times, people ask the question: how long does memory foam last? This depends entirely on the brand, but higher quality foam can last almost a lifetime! Keep in mind that low quality foam made outside of the USA on average has a much shorter time span. Again, many manufacturers outside of the United States have used foreign substances and particles - such as clay - that can be severely damaging to the bed's durability.

In the past, some manufacturers were using petroleum-based substances to produce these products. However, there is a new trend within the industry. Many manufacturers have developed "greener" and cleaner ways to produce memory foam, specifically using plant-based materials. In 2010, State and US Federal Laws have been passed in the United States to require all memory foam products (as well as bedding items in general) to be resistant to open flames.

Also, when you purchase a new one you may initially smell an odor. Do not be alarmed, unless the odor does not subside in the first couple of weeks. This is particularly common for most toppers and mattresses made with this material. It is highly recommended that you "air out" the product for at least 24-48 hours before use. If your product continues to smell after a couple of weeks, you should consult with distributor.

Finally, there are a variety of memory foam accessories that can be purchased for mattresses and toppers. You may need to a new foundation for your mattress in the event that your old one cannot hold weight. Remember, these mattresses are typically heavier than traditional mattresses. Another accessory worth noting is a mattress protector, which can be used to help the product "breathe" and consistently channel air in and out of the material.

Guide to Memory Foam Mattress

Memory foam mattress is a kind of mattress that is made from polyurethane. Besides polyurethane, it is also made from other types of chemicals. The chemicals that are added to the mattress foams gives it the ability to increase in density. Memory foam mattress is also called visco elastic polyurethane foam. The mattress was developed in order to meet the demand of the mattress shoppers.

The history of the Memory Foam Mattress can be traced back to NASA's Ames Research Center. NASA's Ames Research Center funded a project to design a mattress foam that can help to relieve back pain of the astronauts caused by g-forces in the 1970s. NASA believed that the foam material should be used to conform to the shape of the body. Though creating a mold for the body can help to solve the problem, the person would eventually move out of the position. As a result, incorrect pressure points will be formed on the body. Later, the research team from NASA's Ames Research Center found a way to create a foam that can conform the the body's shape. It is a visco elastc foam that can evenly distribute the weight of the body to the foam surface.

The discovery caused Fagerdala World Foams of Sweden to experiment with it and sell it to the consumers. In 1991, Tempur Pedic, a company based in Sweden sold the research mattresss foam to the people in Sweden. After that, Tempur Pedic sold the memory mattress foam to the people that live in United States and Canada. Tempur Pedic's mattress became very popular. The success of Tempur Pedic had caused the manufacturers to create their own versions of memory foam mattresses and sell them to the local consumers.

Synthetic polyurethane foam material is used as the foam memory. The mattress manufacurers will add several types of chemicals to alter the density of the foam. After the chemical is added, the foam will have greater density. Besides, the manufacturer will add a visco elastic foam material. The visco elastic foam is non toxic. The foam weight is detemined by how much chemicals are used in the manufacturing process of the foam. Most memory foam mattress has a weight of 4 - 5lb. Lighter memory foam mattress weight in between 2 - 3 lb.

The quality of the mattress foam is measured by several factors including ILD raing, resiliency and etc. The Indentation Load Defelection (ILD) is a rating that is used to measure the hardness of the materla. Mattress with higher ILD rating are firmer. Mattressses with low ILD rating is able to reduce the pressure points. Despite that, mattresses that are too soft are not good for the body. The resilience rating is used to detemine how many rebound of a steel bound on the mattress. High resiliency indicates that the memory foam mattress is very durable. Expensive memory foam mattresses are made from a combination of the memory foam and lower high resilient layer. The lower high resilient layer and memory foam are able to reduce the pressure point and offer extra support for the lower part of he body.
