While mattresses have typically been made from steel coils wrapped in batting, a newer construction material is now available. Memory foam is now becoming quite popular as a mattress material. A Tempurpedic mattress in Hattiesburg, MS is made from the stuff; now what exactly is memory foam, why does it exist, and what makes it a good place to sleep.
What is Memory Foam?
Memory foam is a polyurethane product that is made by passing gas over a polymer matrix, and this causes the polymer to form the microscopic structure it has. With its structure, the foam can compress to match a shape, and then spring back when the pressure is removed.
Why did Memory Foam Exist?
The original development of memory foam was done in the 60’s. NASA was looking for a material that would be used in aerospace applications, specifically in the cushions of aircrafts. This was supposed to increase survivability of crashes. It was latter repurposed into other safety devices, such as sporting helmets. Its application into mattresses was first used exclusively in the medical community, for cases where patients where immobilized for longer periods of time. Finally, as the process to make memory foam became less expensive, the foam began to be used in the making of commercial available mattresses.
Why Memory Foam Makes a Good Mattress?
The nature of memory foam makes it a good mattress because it can provide support, while also providing comfort. Its ability to spring back slowly lets it reform to different sleeping positions, and it can adapt to different sleeping positions. The benefits are noticed most prominently on people who have to spend long hours in bed. These people, usually patients in a home or hospital setting, can get bedsores or gangrene from the pressure traditional mattresses can cause. They see a marked improvement in these conditions with the use of memory foam mattresses, as the pressure is reduced and blood flow is not interrupted as severely.
