 Memory Foam Mattresses

Memory foam has been developed quite recently, and you have probably already read about its NASA ties and why it was developed. What many people do not know is that there are more distinct kinds of memory foam than latex foam.

Using polyurethane foams that have been adjusted to increase their density and the way they react to pressure and heat; memory foam mattresses are made. The polyurethane foam is made 'viscoelastic' without getting too deep into its chemistry, being able to soften when heat or pressure is applied to it. This pressure and heat come from your body when used in a mattress, specifically the components of your body in contact with it.

When the strain is removed, it molds into certain parts of the body that are in contact with it and easily returns to its original flat form. It could be when you go to bed, or when you get up in the morning. That said there are three different types of mattresses with memory foam. Here's a rundown of each and their relative characteristics.

1. Gel Memory Foam

 

Gel memory foam is thought by many to be an improvement over both the original memory foam and the variation of the open cell. Gel beads are essentially inserted into the structure of the foam. Not only does the gel absorb body heat, but it also provides an open cell structure, all of which help to keep you cool at night.

Some individuals prefer open cell foam to gel foam, but many are unaware of the difference. They choose to go for what makes them more relaxed, and there are also those who prefer the initial memory foam that can give those that need it more help.

2. Standard Memory Foam

 

This is the original type of memory foam that was made available in the mid-1990s to the public. Regardless of your sleeping location, it absorbs your body's pressure. When you sleep, it cradles your body, offers pressure point support and is an outstanding sleeping surface for those with lower back pain and other joint conditions. 

Standard memory foam can help relieve pain in the joints and back, and provide relief for many people when they sleep. Some individuals find it too hot, however. They find that the heat produced while sleeping cannot be released because their body is cradled inside the foam. They feel that the mattress is too hot for them, overcoming any comfort advantages it might offer them.

This isn't noticed by everyone. Many individuals love to sleep on the original form of memory foam mattress that is still very common all over the world.

3. Open Cell Memory Foam

 

Open cell memory foam is a modified type of periodic memory foam that is produced to make the cells in the foam weaker and more open than the initial memory foams. You may find it less thick, or lighter, when you lie on this sort of foam, and that it wicks away the heat produced by your body while sleeping.

It is also springier than the initial memory foam and when you take the body pressure off it it springs back easier to its original location.
