The material which is mainly present in the memory foam is the polyurethane and the additional chemicals which will increase the viscosity and density which is also called as the low resistance poly uretene foam. The best memory foam mattress consists of the foam or the bubbles or the cells which are open and effectively creating the air in which the air can move. The high memory foam is the softens in the reaction to the heat of the body and to change to the warm body in the few minutes and the newer foams may have the nature of the recover to the original shape more and more quickly .
How it works:
The memory foam which is derived from the viscoelastic property from several effects as the internal structure of the material will vary. The network effect is like the force working which will restore the foam structure and when it will be deformed the effect is generated by the deformed porous material which is pushing outwards and it will restore the structure against the applied pressure. The three effects ate like the network effect in which it is like the combination of the pneumatic effect, relaxation effect and the adhesive effect.
The combinations of this combined effects slows the regeneration of the original structure and it will allow the application as the memory foam mattresses . The relaxation effect is created at largest magnitude with the combination of the three forces and which will work against the expansion and it will be caused by the memory foam material. This is the main reason the mobility is deceased in the memory foam and once the force is applied it can’t be removed. The force will make the structural regain and the air will make to take the shape back by the three forces and the beds are so ergonomically designed with immense research and it will take the shape of the body when one sleeps on it . The air which is trapped inside the bed will make it more breathable and makes it more comfortable and heat resistant .
Summing up:
The high memory foam is the softens in the reaction to the heat of the body and to change to the warm body in the few minutes and the newer foams may have the nature of the recover to the original shape more and more quickly .
