AMemory Foam Mattress Topper

There are probably many reasons why you should consider using a memory mattress foam topper, the most important one being you are looking for something that you are not getting currently, a good night's sleep. Rather than spending the money to purchase a brand new mattress and box, a topper might do the trick for you. Whether it's a twin, full, queen, or king memory foam mattress topper that you are looking for, they are all readily available for a lot less money than you would spend on a new mattress and box.

Memory Foam Made Of What Material?

Memory foam is probably best known by the majority of people as the substance that was used by the astronauts to protect them from the extreme g-forces occurring during the take-off of the space shuttle.

The memory foam in mattress toppers is made from polyurethane and other chemicals that add to its viscosity level, thereby increasing its density. This material is also referred to as viscoelastic polyurethane foam. Depending on the chemicals used and its on the whole density, it is firmer in cool temperatures and softer when warm. Higher density memory foam tends to reacts to body heat which allows it to mold itself to the shape of a warm body within a few minutes. A lower density foam is pressure sensitive and will mold more quickly to the shape of the body. This allows memory mattress toppers to be offered in different firmness levels.

Earliest Use Of Memory Foam

Memory foam mattress toppers were originally used in the medical environment to bring relief to patients that were bedridden for long periods of time. The pressure over some of their boby regions decreased or blocked the blood flow to the region, causing horrific pressure sores and/or gangrene. Memory foam mattress toppers helped hugely to decrease such events.

Today's Uses Of Memory Foam

Initially after its discovery, memory foam was too expensive for general use, but today it has become less expensive to produce and now is widely available. Its most common use today is in mattresses, pillows, and memory mattress toppers.

A memory foam mattress is generally denser than an ordinary foam mattress. This makes it firmer and more supportive than an ordinary foam mattress, but a lot heavier. Many people who currently sleep on either a memory foam mattress topper or a memory foam mattress describe the feeling as a blend between the comfort of a soft mattress and the supportiveness of a firm one.

What's That Smell?

Some memory foam mattress toppers and mattresses, when brand new, give off a distinct chemical odor which many people describe as very unpleasant. Over time the strength of the odor decreases, but some people remain sensitive about it. It would be a very good idea to discuss this with your salesperson, as it relates to the warranty, before you make your purchase.
