How Memory Foam Mattresses Are Made
Memory foam mattresses are constructed consistent with their NASA roots. Originally made for astronauts to eliminate the joint stress due to extreme g-forces during lift off, memory foam was redesigned to enter the mainstream market during the nineties. Due to their extraordinary comfort level and body contouring abilities, memory foam mattresses are made with the best possible sleep in mind.
Memory foam mattresses are first constructed using a synthetic polyurethane foam fabric that is generally treated with specific chemicals. Generally, these chemicals do not contain chlorofluorocarbons (CFCs) or Polybrominated Diphenyl Ethers (PBDEs) that have been proven to be extremely harmful to the environment. Instead, many memory foam mattresses are treated with eco-friendly additives that are both naturally hypoallergenic as well as antibacterial. More importantly, memory foam mattresses can also be made of eco-friendly material previously unheard of! Although these products can never be 100% natural or completely soy-based, memory foam mattresses can partially consisted of organic materials conducive to the environment. This is a relatively new trend in the market, but absolutely perfect for the global health crisis while maintaining the quality consumers demand.
Memory foam is considered a visco-elastic material meaning that is retains a temperature sensitivity and a quick reformation ability. It is graded based on four systems: tensile, resilience, Indentation Load Deflection (ILD), and weight. These four components help determine the longevity and durability of memory foam mattresses before they are available to the masses.
The weight of the memory foam is calculated based on the amount of chemicals present in the polyurethane material. The higher the chemical amount, the denser and thus, the more visco-elastic it is. However, the density does not define the hardness of the foam. This is done through the ILD rating system.
The ILD measurements dictate how hard or soft the foam material will be. For example, a 25% rating is the actual weight, in pounds, needed to administer a 25% compression of a four inch foam layer. This is an important rating to look for as a consumer. A lower rated top layer in a memory foam mattress is wonderful in alleviating pressure point stress. It is important to consider many different levels as too soft of a top layer can aggravate the pain rather than relieve it, so it is important to choose one that is conducive to your body type.
A resilience rating is based on rebound. This is determined using a steel ball that is released from thirty-six inches in the air. The higher the resiliency, the higher the quality of the foam mattress is. This is especially important for those who are overweight or of large stature as it ensures the durability and longevity of the memory foam mattress by reforming time after time.
Tensile measurement is also an important grading system component as it calculates how far the foam can stretch (in pounds per square inch) and elongate before rupturing. This is essential for consumers as a memory foam mattress is used daily and should last quite a while.
Memory foam mattresses are wonderful products that are impeccably made with the consumer in mind.
