What are Memory Foam mattresses?
The invention of memory foam is often credited to NASA. In the 1970's they invented a new type of foam to provide astronauts greater support and protection on G-force heavy shuttle launches.
This visco elastic quality means that a memory foam mattress will offer you a more supportive night's sleep than any normal sprung mattress. Your body weight will be more evenly distrubuted, and the pressure you feel as you lie down will be effectively less. These pressure relieving properties have resulted in memory foam mattresses surging in popularity.
Memory foam is the common term for 'visco-elastic polyurethane foam', which is a temperature and pressure sensitive foam. This means that when you lie on a memory foam mattress, your bodyweight and heat causes the foam to shape itself to your body ensuring that your whole body is in contact with the surface of the mattress. As your body moves around the mattress the form will re-adjust and reshape to your new position.
In addition to these key advantages, our visco-elastic products also react to body temperature and ambient temperatures, softening with heat and more easily adjusting to body contours.
Advantages
Visco-elastic foam's unique physical characteristics have led to its popularity in the bedding and medical industries. Due to its conforming. people with impaired mobility, confined to wheelchairs or hospital beds (especially burn victims) can benefit from the foam's capacity to redistribute weight and surface pressure, potentially reducing decubitus ulcers (bed sores) caused by aggravated pressure between the skin and bony areas of the body such as beneath heels, hips, elbows and the back of the head. The memory foam mattress improves the blood circulation, making you feel "on top of the world" when you wake.
Pressure Reduction and Pressure Relief
Because visco-elastic foam can closely conform to the shape of the human body, it can efficiently distribute pressure over the whole surface.
Pressure-mapping equipment is often used to calculate the degree of weight distribution. During the mapping procedure, computer programs monitor pressure. The body's impression is graphed to show which areas endure the most pressure (namely the shoulder blades, posterior region, head, heels, calves & elbows).
