Guide to Memory Foam Mattress

!±8± 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.

Bed Reviews and Ratings - How Do Memory Foam, Air, Latex and Innerspring Compare

!±8± Bed Reviews and Ratings - How Do Memory Foam, Air, Latex and Innerspring Compare

If you are looking for bed reviews and ratings, you are in the right place because I have some important data to share with you.

My research team has conducted extensive bed research by gathering data from over 3,100 bed owners. This article covers the various kinds of beds in order of how they scored in our research.

Latex

Latex beds overall had the best score. About 90% of latex bed owners communicated that their mattress was comfortable in their opinion. Our research suggests that latex beds tend to have a smaller number of downsides than other bed types. Case in point, latex generally has good toughness and tends to not make the sleeper hot or give off a chemical smell initially, at least not as much as most other bed types. Further, a latex bed can be custom crafted to satisfy your personal firmness-level liking.

Memory (Visco-elastic) Foam

Memory foam beds overall scored behind latex beds and about equally to airbeds. Around 85% of memory foam bed owners indicated that they found their bed to be comfortable. The open cell structure of memory foam means it can equally support and contour to every part of the body.

Air

Air beds, like the Sleep Number Bed, scored nearly the same as memory foam mattresses. Air bed owners indicated that they appreciate the reduced pressure points that the air provides as well as the ability to change the firmness by increasing or decreasing air in the bed via an electric pump.

Innerspring Coil

Innerspring beds overall scored at the bottom. Around 55% of innerspring bed owners indicated that their bed provides good comfort. The shortcoming of these beds centers around sagging, in which peaks and valleys appear within just a few years of purchase and work to undermine comfort and support.

2 Pound Memory Foam and 5 Pound Memory Foam - Difference Between the Memory Foam Densities

!±8± 2 Pound Memory Foam and 5 Pound Memory Foam - Difference Between the Memory Foam Densities

The different weight classes at the reviews (density) is a complex subject, and many consumers could be in the amount of jargon often used by sellers of bedding feel overwhelmed. However, upon installation of the jargon of £ 2.5 to 5 kg, the theme is quite simple.

The density is calculated by dividing the measured weight of a cubic foot of foam. Consequently, a block of foam measuring twelve inches (one foot) weighed on all six sides and the weight of the foam block as itsDensity. The higher the density of the foam as product reviews.

The amount of material in the product is important, because they like the product feels and reacts hit. So what's the difference between £ 2.5 and £ 5 density?

The £ 2.5 density foam is a cost that is often produced in China. Because it uses less material to produce density of 2.5 pounds, many manufacturers around the world have started their cheap versionthis product. It is this cheap, lightweight density that is sold out of many big-box chain stores. In fact, most of the memory foam sold from the big-box chain stores, like Wal-mart, JC Penny, Belk, Target, etc., is the 2 pound or 2.5 pound densities, though much of the it sold in these big-box chain stores is not labeled with a density rating.

The 2.5 pound density can be a quick and cheap solution to a hard mattress or dorm-room bed, however, it lacks many of the qualities that have become synonymous with memory foam. It is soft but lacks support, and it has a slow recovery time that does not allow it to properly conform to the body's shape. Also, much of the 2 pound and 2.5 pound is cheaply made and breakable. Therefore, much of the memory foam being sold out of big-box chain stores is giving individuals the wrong impression of the product.

On the other end of the density spectrum, we have the 5 pound density that was made world famous by Tempur-Pedic. This density is luxurious, durable, and well crafted and will retain its recovery time, support, and comfort for many years to come.

The 5 pound weight is one of the higher densities currently available (others being 8lb and 12lb densities), and it has the most material per cubic foot; therefore, it is the most expensive. Also, it is the firmest product available and has a slow recovery time because it will hold the body's impression longer due to the amount of foam material present it the product. This can make moving about difficult for some customers, and a few individuals have claimed it feels like sleeping in a trough.

There are, also, medium densities. The 3 pound and 4 pound density is, usually, well made, durable, and comfortable. These two densities are more expensive than the 2.5 pound foam, but they are cheaper, softer, and will recover quicker than the 5 pound density. These medium densities are used to create high quality memory foam products, such as mattresses, mattress pad toppers, pillows, and seat cushions.

In fact, many individuals prefer the softness and quicker recovery time of the 3 pound and 4 pound densities to the firmer 5 pound densities.
