Memory Foam
What is Memory Foam?
Memory foam is a polyurethane material that is sensitive to pressure and temperature, used especially in mattresses, where it molds to the shape of an individual's body.
1.The basic kind is made out of a polymer known as polyurethane. This is a material that is commonly found in most sofas, mattresses, car seats and spray foam. Memory foam is a very durable type of material if it has a high enough density and is also known for providing good support and excellent pressure relief. These kinds of beds usually have a longer lifespan than spring mattresses.
2.Memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam. The foam bubbles or ‘cells’ are open, effectively creating a matrix through which air can move.
3.This type of foam has been around for 50 years. In fact, it was originally invented by NASA as material that would have been used for the comfort and safety of astronauts during launch. People liked it so much it started being used in more and more instances and really blew up in mattress form when Tempurpedic released its memory foam mattress. Now you can find it in seat cushions, pillows and even shoes!
4.Memory foam has certainly progressed a long way since it was first invented. Visco elastic memory foam is often combined with materials that regulate the temperature of the human body. The consolidation of these materials usually results in a cool and supportive place to sleep. It is typically a dense, yet comfortable feeling for a sleeper. Usually, it is a good idea to check out the density of the foam mattress that you are considering. If it is below a certain density level, it may not be a good quality and might not perform as well or last as long as you would like it to.
The Advantages of Memory Foam
1.The method of manufacturing memory foam varies depending on the formula used by the company. These different formulas change the qualities of the foam. For instance, some types of memory foam might be more resilient to changes in the shape of a body that is lying on them. It might take longer to mold to the exact shape of the person. Memory foam is very solid and dense. This means that most substances cannot pass through the surface. However, the foam also displays elastic properties. It is able to recover its shape over a certain period of time. It will soften when you lie on it, but will return to its original shape when you get up.
2.One of the great benefits of solid memory foam is it’s able to use your heat and body pressure to form to your exact shape. The “visco” part of visco elastic is what comes into play here. Your body heat actually softens the memory foam, making it more viscous. This is what allows you to sink in. It essentially creates a mold of your body. When you get up from the bed, the foam goes back to how it was originally. That would be the “elastic” part.
3.This will make a more comfortable sleep for people, as the mattress is perfectly indented to suit them. This is also good for supporting the alignment of your body. Sleeping on a natural curve is good for your spine, and promotes lumbar support.
4.A great feature of memory foam is that it’s also helpful in terms of relieving the pain on pressure spots. If you have arthritis, or joint pain, then these beds might be able to help. It cushions you, and will reduce any impact you might otherwise encounter.
5.Older beds which use only a pillow top or some sort of soft top layer, have a tendency to begin wearing out over time, which allows the underlying springs to start making more and more of an impression. Eventually, these springs can serve as pressure points on the bed, causing you discomfort.
6.Memory foam, for the most part, eliminates this. Many memory foam mattresses don’t even include springs, and in hybrid mattresses that use both, the foam serves as a fair enough protector between the two. This is, of course, good news for anyone who suffers from things like back pain.
7.When using a memory foam mattress, it is less likely that you will be able to feel your partner moving. There is a reduced chance that you will be bothered by their getting up or tossing and turning. This is due in part to the density of the mattress. Because you sink in, movement is basically absorbed by the mattress, rather than being transferred, as would happen with a traditional spring mattress. This is good if you are a light sleeper and are easily awakened.
8.Another benefit is that memory foam can be hypoallergenic. It has a very dense structure, which is good for reducing the number of allergens that can build up. Dust, mold and other allergens will not be able to find a way into your mattress. This is very helpful for people who have allergies, as they are very often prevented from getting a good night’s sleep.
