Memory Foam Mattress
There are many different types of mattresses available to buy but it is widely accepted that to experience the best night’s sleep, memory foam is the best option. Two types of mattresses that are commonly purchased are traditional coil spring mattresses and memory foam mattresses. Many consumers feel that the benefits of the memory foam mattress significantly outweigh those of the coil spring mattress.
There are different types of foam mattress: latex (which springs back when you get up) and visco-elastic, or ‘memory foam’, which doesn’t, but leaves an imprint of your body. But you have to be careful, warns BackCare, not to get stuck in your own moulded hollow.
Lying in one position can create stiffness. A mattress should be supportive enough to take the weight of your body without sagging, but firm enough for you to turn with ease.
Memory foam is manufactured from visco elastic polyurethane foam and has some unique qualities. Snoozing on a full memory foam mattress causes it to conform, or mold, to the shape of the body, but it will then return to its initial shape, consequently the name memory foam. It was first made for NASA nearly 40 years ago, but as production costs decreased it was made available to the public in the 1990s. Since then it has enjoyed an impressive rise in status.
The majority of the confusion with visco memory foam is because of the many densities and levels of firmness that are for sale. Density is the weight of a 1-cubic foot section of foam. If a 1-cubic foot section weighs 5 pounds its density is also 5 pounds. Normally, if the foam is denser it will have a longer lifespan, but the less soft it will feel.
ILD, short for Indentation Load Deflection, is how firmness is rated. ILD is the amount of power required, measured in pounds, to cause a 1 inch indentation in the foam. Measuring the Indentation Load Deflection is done by laying a 50-inch disc onto a section of foam that is measured at 4×15x15 inches. The amount of weight in pounds necessary to press the foam down 1 inch is its ILD rating. If it takes 14 pounds to compress the foam down an inch its ILD rating is 14. A mattress that has a lower ILD rating is softer.
Sleeping on a typical spring mattress will cause more force on specific points such as the hips or shoulders. A memory foam mattress will distribute the body weight of a person more evenly and over a greater area. This will lessen the degree of pressure in any specific area which can result in a more restful snooze and decreased back or joint aches.
Memory foam retains heat and is why many individuals do not care for it. When somebody lies on one of these foam mattresses it will originally feel stiff. Later, as soon as the heat from the body is transferred to the foam it will begin to become softer, causing it to conform, or mold, to the persons body curves. The foam below the heat will stay cooler and less soft, providing great support, while the warmer foam will be softer, providing added comfort. Many people with lower back pain will notice that their ache goes away due to sleepingon a full memory foam mattress.
