To understand this material better, you will have to travel back in time to the late 1960s. It has connections to the Apollo space program. This program puts man on the moon in 1969. NASA needs cushions for its astronauts. The stress and force of takeoff and orbit re-entry needs special considerations.
NASA signs up people to work on this project. They also use a space engineering company. After considerable experimentation, they come up with a product. It is a visco-elastic material. Visco is similar to viscous. Viscous means resistant to flow. Water will pour from a glass or container. It will easily flow from the container. Syrup will be resistant to this same type of flow. If you tip the glass or container back, part of the syrup will return to the container.
Elastic means stretchy. If something has the property of returning to its original shape, it is elastic. If you stretch a string and then let it go, there will be little rebound. Take an inner tube or a rubber band. Stretch them out and let go. You had better stand out of the way. The rebound will be significant. The inner tube is attempting to get back to its original form. In the process, there is a great deal of energy expounded.
Visco-elastic takes the properties of viscous and elastic and combines them. A visco-elastic material will act like syrup or honey at cooler temperatures. It is resistant to flow, also. However, when you heat the material, something happens. It now behaves more like a liquid.
Imagine a large rubber band or inner tube. You stretch it out and it snaps back very slowly. The energy is not released all at once. It is slowly released in waves or cells. The engineers at NASA want something like this. That is how visco-elastic material is developed.
When an astronaut goes through take off, he is thrown back into his seat. In a normal cushion, there is a great deal of shock. If he sits in visco-elastic material, he is slowly thrown back and slowly returns. The shock of take off is absorbed into the material and not his spine or brain.
Suppose you are in a bathtub of water. There is a toy boat floating on the surface. Whenever you move, you displace water. Waves are created. They spread out and affect the toy boat. The boat will rock to and fro. It may even capsize.
Imagine that you are in a bathtub of heavy syrup. This special syrup is also elastic in nature. When you move, the syrup absorbs the motion, slowly. The toy boat is unaffected. You see this demonstrated with people on a bed. A glass of wine is placed on the bed. Someone jumps up and down on the bed. The wine is not spilled. This is because the bed is made from a visco-elastic material.
This cushion material works well. However, it sees little use in space. Earlier material has a strong smell attached to it. It is too expensive for beds, at this time. It sees use for expensive racehorses, however.
A thoroughbred racehorse needs special care when ill. There may be times that they are injured or have surgery. They need to be in an upright position while recovering. This is to make sure that their blood can evenly circulate throughout their bodies. If they lie on a large bed of visco-elastic material, the problem is solved.
This material is also found to inhibit bedsores. If a person lies in bed too long, their circulation is affected. The pressure of the bed can actually cause skin ulcers. This is also called bedsores. Long periods of time in a wheelchair can do the same thing.
This material is used in many hospital situations. It works very well. More and more hospitals use this material as bed padding. It sees wide use in wheelchair cushions, too. As it becomes used more in the medial industry, the cost slowly falls. Eventually it is feasible to use it for beds.
These beds can make your sleeping much more comfortable. You will not feel your partner toss and turn about. It will cushion you without putting pressure on your skin, back, and entire body. These beds may have an unusual odor when new. It will gradually fade, over time. Some manufacturers recommend ventilating your bedroom well for the first few days. There are some beds made to be friendly to the environment. They will not have this initial odor.
Summary
The memory foam mattress has an unusual history. It starts in the space program in the late 1960s. Engineers work on cushions to ease the shock of space flight. It does not see much use. Finally it is used for recovering racehorses. It is then discovered to work wonders, preventing bedsores. It finally makes its way to the consumer. This space age technology can improve your sleep. You will not feel your partner moving about. It will cushion you softly, yet firmly.
