About Memory Foam
Memory foam is a product of the space age. It was developed in 1966 by NASA's Ames Research Center to improve the safety of aircraft cushions. This newly developed temperature-sensitive polyurethane foam was later commercialized for use in medical and sports equipment such as football helmets. NASA eventually released this unique material to the public domain in the early 1980s.
Memory Foam Properties
MEMORY FOAM MATTRESS molds to the curves of your body – allowing more "give" in the pressure points for the shoulders, knees, hips and head. The result is a significantly more comfortable mattress and a much more restful night's sleep.
Memory foam is temperature and pressure sensitive. At lower temperatures it becomes more resilient. At higher temperatures it becomes more elastic. What this means is that as you are lying on a memory foam mattress, it will react to your body's weight and temperature.
Memory foam mattresses are usually more dense than other foam mattresses. This makes them more supportive, but also heavier. Most memory foam has a density of between 2 and 4 pounds.
Memory foam with a lower density will have a shorter life span due to the compression that takes place after repeated use. Memory foam density of 5 pounds or more is considered higher quality with better compression ratings over the life of the bedding.
Memory Foam Benefits
Memory foam offers many benefits. The greatest is its ability to reduce pressure on the body, joints and spine. If you suffer from allergies, memory foam is both hypoallergenic and dust mite resistant. Its unique properties often provide significant benefits for those with poor circulation, fibromyalgia or osteoporosis.
How to Select the Right Memory Foam Mattress
It's important to understand that the elasticity of memory foam is affected by temperature. The TG (glass transition curve) measures the temperature range where the memory foam will respond correctly.
Any temperature too high – and the memory foam will become too soft. Any temperature too low – and the memory foam becomes too hard (like glass) and can take 24 hours to soften again.
Most memory foam sold today has an elastic temperature range of approximately 11 degrees. This severely limits the ability of the mattress to operate satisfactorily. Our memory foam has a TG curve with approximately twice that range. Why is that so important? Because most people like to sleep in a cooler environment ‐ and our memory foam has the ability to be elastic at much lower bedroom temperatures so you won't experience this typical hardening effect.
Memory foam density is measured in pounds per cubic feet. Generally speaking, the higher the density – the higher the pressure relief and the more expensive the mattress will be. We do not recommend going below 3 pounds in density. Lower density memory foam will NOT last as long – and will not relieve pressure as well. Our density is 5 pounds.
Firmness in memory foam products comes from a combination of the density of the foam as well as the ILD rating. A normal ILD range for memory foam falls between 8 and 15. Anything below 8 ILD or greater than 16 ILD will greatly diminish the memory foam effect. Our firmness is 15 ILD.
Memory foam can be produced with either an open-cell structure or a closed-cell structure. The tighter the cell structure, the less airflow through the foam. "Breathable" memory foam will have a more open cell structure – allowing higher airflow, better recovery and lower odor retention at the packaging stage. We have an open cell structure.
The majority of memory foam is made with two types of compounds:
TDI (toluene disocyanate) is most commonly used.
However, they are an OSHA class 3 carcinogen and are known to release the hazardous carcinogen TDA (toluenediamine) into the air after production.
TDI produces a grainier foam with a slower recovery time. These mattresses are more sensitive to temperature and often tend to hold odor longer than MDI memory foam.
MDI (polymeric iso) is a more environmentally friendly product that reduces the amount of off-gassed chemicals released during production and inside the home.
MDI produces a creamier foam with smaller cell structure. It has a better air flow and faster recovery time. It also helps avoid the heat retention and noxious smell of TDI foam. In addition, it is extremely durable and less sensitive to temperature.
Made in the USA vs. Asia. (Buyer Beware).
Unfortunately, not all memory foam is produced equal. Many companies will assemble their mattress in the USA, but will buy the memory foam from Asia to save money. Many hazardous chemicals that have been banned from the United States are still widely used in China.
Fire retardants containing PBDEs (polybrominated diphenyl ethers) are still widely used in China even though they are banned in the USA as a potential health hazard. In addition, there have been stories of Asian factories adding clay particles to their memory foam to increase its density for sales and marketing purposes.
Certipur-US for Consumers. An Extra Measure of Assurance.
It is difficult to be sure of the quality or the composition of these foam imports – so we feel the Asian imports may not last as long, be as safe to sleep on or offer enough support. We encourage you to protect yourself – and make sure that the memory foam you buy is produced in the USA and meets Certipur-US standards.
All foam used in our Sleep Comfort mattresses is manufactured in Arkansas by Hickory Springs and meets Certipur-US standards – for your satisfaction and protection.
