Gel Infused Open Cell Structure Memory Foam for Maximum Air Flow

Sleep Number Air Mattress Comparison

In the 1960s, NASA was looking for a better type of foam for airplane seats. Little did they know that the new type of foam developed would eventually become a mainstay of specialty sleep products (not to mention slippers, dog beds, etc.) Also called visco-elastic foam, memory foam continues to grow in popularity today.

Memory foam is created by infusing polyurethane foam with temperature sensitive adhesives. This creates a foam that is general more dense than standard polyurethane foam and is reactive to not only pressure, but also heat. The result is a foam that molds to the sleeper's body - giving way where the body exerts more pressure (and thus more body heat) into the foam (the hips, shoulders, etc.), but providing support where the body does not press into the foam as much, such as the lower back and legs. The temperature sensitive adhesives in memory foam allow the foam to soften when body heat is applied. When the heat source is removed, the foam itself continues to retain the heat, and thus the impression of the heat source remains (think of the classic memory foam photo of a hand print) until the foam slowly cools. This is the "memory" aspect of memory foam.

The unique properties of memory foam help evenly distribute body weight across the mattress. When a person lies down on memory foam, his or her body heat softens it in appropriate places. This helps support your body where it needs support - around the natural curves and lines of your body. When looking for a good night's sleep, support is key. Some people have taken this to mean that the firmer a mattress is, the better. But if you think about sleep that way, there would be no more comfortable surface than a cement floor. Certainly, there aren't too many people who would choose cement as their sleep surface, but no one could argue that it's not firm! So, obviously "the firmer the better" is not necessarily true; what is true is that proper support of a sleeper's body and spine is necessary for proper sleep. Keep in mind that there are as many opinions about what constitutes proper support as there are sleepers in the world, but many, many people believe that memory foam's ability to contour to a sleeper's body provides a level of support that cannot be found using any other material. As with latex, memory foam enjoys excellent motion isolation characteristics. This means that your sleep partner's tossing and turning will be less likely to affect your sleep - certainly a plus!

So what are the downsides to memory foam? The most common complaint about memory foam is that because it is a heat sensitive material, it absorbs body heat and thus "sleeps warm." Traditionally, memory foam is not known as a material that "breaths," meaning that air does not easily pass through the material. However, makers of memory foam have created second and third generation foams with an open cell structure designed to increase the foam's breathability and help sleeper's enjoy memory foam's advantages. We use only the highest-quality,latest generation memory foam so that you will sleep cool and comfortable, even on those hot summer nights.
