Our memory foam mattresses are constructed of 100% environmentally-friendly, soy-based memory foam. The mattresses available consist of two, 2" layers of memory foam, the first being 4 lb density, and the second being 5 lb density. In addition, the base of our mattresses are made of two, 3" thick poly foam layers, with the base layer being the thickest and firmest. All of our mattresses are 10" thick and comprised of this construction.
Most of the memory foam industry can give thanks to the innovations of the TempurPedic company. In the 1980s, they were the industry leader of medically useful mattresses and developed a "visco-elastic" foam, that would later become dubbed "memory foam". This foam was an open-celled combination of polyurethane and other agents that would create a mattress firm enough and supportive enough to sleep on, with no pressure points. The material became instantly useful in wheelchair cushions, hospital beds, and disability cushioning.
Over the years, competitors have risen and developed their own proprietary combinations of materials to create their specific blend of memory foam. Many, including TempurPedic, started adding latex to their mattresses to improve airflow and support at different layers. Memory Foam Doctor's memory foam mattresses are hypoallergenic, allergen and dust mite free, breathable, supportive, and comfortable, much like TempurPedic but with the added benefit of being 100% eco-friendly in their construction thanks to our use of soy-based materials.
Through our research at Memory Foam Doctor, we've discovered that the less dense layer of memory foam on top made our mattress soft initially, while adding enough support for the average individual. We determined that in order to offer more support and maintain that initial softness on lying down, we need to use a more firm layer underneath our softest top layer. When you lay down on a memory foam mattress, you'll initially feel the stiffness of the memory foam, then as the cells start to "squash" they develop a supportive cradle that contours to your body. We wanted the top layer to be soft as your favorite inner spring, while the second layer would offer the supportiveness you were looking for from a firmer mattress. In essence, we've structured our mattress as such to offer the best of both worlds.
The thinner density of the top layer (4 lbs), allows for more dissipation of body heat and improved airflow, while also creating that softer feeling you would get with a down top on an inner-spring mattress. The thicker density layer creates more of the support you've come to expect and appreciate from memory foam mattresses, without the rigidity and pressure points created by an inner-spring mattress of comparable firmness.
The orthopedic foam base layer on all Memory Foam Doctor memory foam mattresses is a proprietary blended material used to create additional support without the necessary density of memory foam. If you were to create a layer of memory foam this thick and supportive it would need to be upwards of 8 lb density. The firmer materials used in the base layer allow us to make a more supportive underlying mattress that offers excellent back and hip support without the stiffness of a firm inner-spring mattress.
Like the top layers, stacking two different firmnesses on top of each other offer more initial and prolonged comfort, while also providing you with a supportive and cradling sleep. The entire design of our mattress was centered on creating a uniquely comfortable and supportive mattress that didn't produce "sweet spots" or sag at any point.
Our cover is made from a hypoallergenic, zippered material known as CoolMax®. We have an in-depth article detailing the importance and revolutionary nature of this material, called "What Is CoolMax®?". The most important takeaway from the article is that our CoolMax® Covers are designed to help improve air flow, moisture and heat dissipation, while maintaining comfort. The CoolMax® material was initially developed by DuPont in the 1980s for extreme athletes as a means of maintaining a cool body temperature during physical exertion.
