A Memory Foam Mattress Is Comfortable

A memory foam mattress is exactly what the doctor will order for us today! Most of us are tired and stressed, by the end of the day and need a good night’s sleep to recover and feel totally relaxed and ready for the next day. This is where a memory foam mattress which is visco-elastic in nature really helps.

What is the memory foam mattress? A memory foam mattress is made of polyurethane and other chemicals that increase its viscosity level. The foam has the distinction of being stronger at low temperature and warmer at mild temperatures. Depending on the density of memory foam the mattress reacts to body heat and molds itself according to the shape of the body in minutes.

Originally developed for NASA space programs, memory foam is a material that compresses easily when exposed to body weight and temperature. When the pressure is removed, the material regains its shape within seconds. These mattresses may have different levels of density, depending on the chemicals used in their composition.

In addition to being known as memory foam, this material is called temperature sensitive and pressure relieving visco-elastic foam.

The memory cells in the foam mattress undergo visco-elastic deformation when weight is applied. When compressed, the cells transfer air pressure to the adjacent cells. So the pressure is evenly distributed across the memory foam, thereby reducing the pressure felt in any one region.

How is a memory foam mattress different from a spring mattress? Traditional spring mattresses undergo compression, but the springs return to their original shape immediately. When weight is applied to a traditional spring mattress, it repels with equal force against the body. This creates pressure points that cause discomfort and pain. In the case of memory foam mattresses these compress easily when exposed to the temperature and weight of your body. As the pressure is evenly distributed, a mold is formed around the body, reducing pressure points.

The fundamental difference lies in the quality of sleep. A bad night can cause a feeling of lethargy throughout the day. One night spent sleeping on a memory foam mattress means sufficient rest and relaxation so that you can wake up fully rejuvenated in the morning.

Not all mattresses are temperature sensitive. The quality of the best latex mattress can be very different depending on the quality of the foam, which in turn depends on the density. This creates a big difference between various memory foam mattresses.
