What is a Memory Foam Mattress?

by Bryan Dewhurst on February 04, 2020

The question that many people are asking these days is what is a memory foam mattress? It is a whole bed made from memory foam and has the ability to sense your body’s weight and temperature so that it is able to adjust to your shape, minimize pressure points, aid in alignment as well as reduce tossing and turning while sleeping.

It was first created by NASA (National Aeronautics and Space Administration) in the 1970’s. But the first generation memory foam mattress was too brittle and had a habit of breaking after just one to two years of use.

Ten years later, a Swedish company that worked closely with NASA in creating the first memory foam mattress got it right. This one was made using a spongy, gel-like plastic whose open cells could deform under pressure and re-shape back to its original form.

Just to prove how effective it is, one brand called Tempur-Pedic sells these mattresses to hospitals. Patients who used the memory foam mattress claim that it has remarkably reduced pressure on joints whenever they lie down. It also gives good back support.

Memory foam mattresses were first introduced to the market in the early 1990’s. The problem at that time was that they were very expensive. But it soon changed as other companies were able to produce similar products.

But the story of the memory foam mattress doesn’t end there. If it is good for the back, then it could also have benefits for other places in the body which is why the foam is also used on other products such as mattress toppers, pillows, office furniture, automobile seat padding, infant cribs, car seats, wheelchair cushions, hip pads, sweat pads, computer cases, movie theater seating, pistol gloves, ear plugs and tennis racquets.

The price of the memory foam mattress is from $300 to $600. This does depend on the density that you wish to buy though. The thicker they are, the more expensive they are. Most people get those that weigh 3 to 5.5 pounds since this is what fits their budget.

Some of these are sold in stores but you can also find them online. They come in different sizes so you can get one for every bedroom in the house and if you find these expensive, perhaps you could consider getting a topper.

A topper is much smaller than the foam mattress since you put this over an existing mattress. Its thickness is 1 to 4 inches thick. If you plan to put this over a spring mattress, make sure that it is not more than 5 years old.

You might be thinking that all the companies that make memory foam mattresses use the same materials to make their product. But it is not true because some use liquid foam while others use a vacuum injection which means they do not rely on gravity to provide consistent density and eliminate variation. So when you are looking for a memory foam mattress, ask the salesperson what material is used.

A lot of people say that the memory foam mattress is out of this world given that this was first designed for use by astronauts. Since it is used in almost every type of furniture these days, you can now say that it has taken the world by storm.
