Memory Foam: Body
built 607 days ago
Memory foam is made from polyurethane with additional chemicals that add to its viscosity level, thereby increasing its density. It is often referred to as visco-elastic polyurethane foam. Depending on the chemicals used and its overall density, it is firmer in cool temperatures and softer when warm. Higher density memory foam reacts to body heat which allows it to mould itself to the shape of a warm body within a few minutes. A lower density memory foam is pressure-sensitive and will mould more quickly to the shape of the body. The example often used to demonstrate its properties is that a hand pressed into the foam and then removed will leave a clear impression in the foam.

Memory foam was first marketed to people that had trouble sleeping because of bed sores or other medical problems. As compared to other bedding materials made of latex, cotton, or wool, there is just nothing like memory foam in the way that it conforms to your body. It reduces the pressure points that naturally bother people when they sleep, but it is a soft material and isn't necessarily very supportive.

Memory foam is made from a visco-elastic material that contours to your body's shape. Each time you lie down, no matter what position you are in, your heat and weight will cause the foam to mold to your body's exact curvature. Your weight will be distributed evenly and your spine will remain in its normal position.

For customers familiar with latex, it is important to contrast that Memory Foam feels more molded. Latex tends to bounce back when touched, whereas Memory Foam will offer the sensation that your body is being conformed to. Both types of foam will reduce pressure points.

[One] wonderful property of memory foam is that it has the elastic ability to form back to its original state. So after sleeping on it, the elastic properties allow it to return to a firm base. This same quality is what allows memory foam the ability to contour naturally and give support around the natural curves of your body.

Some memory foam companies sell memory foam "mattresses" that are only 8, or even 6 inches thick! A mattress this thin simply cannot support your body correctly. The Dream mattress from Sleep Aid measures 10.5 inches 4 of which are top grade memory foam!
