Memory foam is a polyurethane-based chemical compound. It is mixed with other compounds which increase its density and viscosity. It has a viscoelastic behavior. Memory foam can be used for the manufacture of mattresses, pillows or cushions.
Advantages of memory foam mattresses
Researchers claim that heat sensitive, memory foam mattresses react to your body temperature. Firm at first contact, it eases up gradually under the weight of the body. Under the influence of heat the foam cells adapt to your body, allowing a homogeneous distribution of pressure zones and the relaxation of your muscles for good night’s sleep.
The memory foam mattress has another specificity: it returns to its original shape as soon as you make a move then readjusts to the newly adopted position. So you enjoy its benefits all throughout your night.
With the enveloping softness of memory foam, the usual pressure points (back, neck, pelvis, shoulders) are fully supported, but without compression, as the spine retains its original position and the muscles are completely relaxed. This innovative technology also improves blood circulation, reduces body movements during sleep as well as cervical and back problems. All of which guarantees a comfortable and good night.
An individual turns on average 40 times a night, but that makes 80 risks of waking up for couples! However thanks to memory foam mattresses, the movements of one are absorbed so as not to hinder sleep for the other. Given the respective sleep patterns, positions for sleeping or the morphology of each, memory foam provides excellent sleeping independence and allows you to find a restful slumber.
The more the temperature drops, the more the mattress/pillow hardens while it becomes softer and expands when the temperature is warm. Generally, memory foam is harder at room temperature; but when the body comes in contact with the mattress, it softens and is modeled to suit the body. If you press you hand on the foam and remove it the shape remains.
Praised by health professionals, memory foam mattresses and pillows have the potential to relieve any neck or back pain or even prevent them. A good night on a comfortable mattress is an indispensable luxury. Today, as everyone is chasing his dreams, restful sleep is a necessity. The density and firmness are qualities that make it very unique. The denser it is, the better its quality. The average memory foam on the market has a density between 1.5 pounds and 5.3 pounds, the most common densities being 3 pounds, 4 pounds and 5 pounds. The firmness of the memory foam is generally between 6 and 40 ILD (Indentation Load Deflection).
In lower densities, polyurethane foams often have a fairly firm initial contact before sinking (plateau effect).You can find foams with similar densities but totally different comforts. A polyurethane mattress is sensitive to the quality of the bed on which it is based, particularly if its a large one.
