A memory foam mattress is just what the doctor ordered for the hectic lives we lead today! Most of us are tired and stressed by the end of the day and need a good night's sleep to recuperate and feel totally relaxed and ready for the next day. This is where a visco elastic memory foam mattress really helps. |
A memory foam mattress is made from polyurethane and other chemicals that increase its viscosity level. This increases its density level. The foam, thus, has the characteristic of becoming more firm in cool temperatures and softer in warm temperatures. Depending on the density, a memory foam mattress reacts to body heat and moulds itself according to the shape of the body within a few minutes. A low density memory foam mattress will mould faster into the shape of the body.
Originally developed for the NASA space program, memory foam is a comfort material that compresses easily when exposed to body weight and temperature. When the pressure is removed, this material resumes its shape within seconds. A mattress made with visco elastic polyurethane foam can be of varying density levels, depending on the chemicals used in its composition.
Apart from being known as memory foam, this temperature sensitive material is also called visco-elastic foam, pressure relieving foam, slow release foam and slow recovery foam.
Traditional spring mattresses compress, but spring back to their original shape immediately. When weight is applied to a traditional spring mattress, it pushes back with an equal force against the body. This creates pressure points, leading to discomfort as well as aches and pains. On the other hand, a memory foam mattress compresses readily when exposed to the temperature and weight of your body. Since pressure spreads evenly, a mould is formed around the body, thereby reducing pressure points.
The basic difference is in the quality of sleep. A poor night's sleep can result in a lethargic feeling throughout the day. A night spent on a memory foam mattress means adequate rest and relaxation and waking up completely refreshed in the morning.
