What is Memory Foam all about?

Unless you’ve been living under a rock, you have probably heard of Memory Foam Mattresses, also referred to by the brand name Tempurpedic mattresses and their purported benefits. Many of are naturally skeptical of the ‘next big thing’ that is supposed to improve our quality of life and naturally beg the question “Is it really worth it?” or “What can memory foam do for me?”

With the vast and expansive amount of information available on the internet, one can gain a better understanding of the product and make an informed decision based on personal needs. First off, what is memory foam made of? Memory foam is actually polyurethane foam with a special additive that adds heat sensitive and elastic like capabilities. What this means to you is that the memory foam mattress will respond to the heat of your body and contour to your shape.
The heat and weight sensitive foams mean your heavier areas will sink further into the bed to keep your spine in a straighter, more aligned position. In a coil/spring mattress, the hips and shoulders are forced up at an unnatural angle that places most pressure on the lower back which is where most people report discomfort. In the foam beds, the design allows the hips and shoulders to sink in, while supporting the lower back.

Perhaps the most proven and lauded benefit is the pressure reducing capabilities of memory foam. This is the only benefit that has been medically proven and is very significant. Memory foam was first utilized in the health care industry for this very reason. Side by side studies comparing visco-foam, basic foam, coil, and air mattresses and their relative ability to reduce pressure sores on the bedridden put visco foam (memory foam) in first place. The unique cell structure distributes pressure evenly across the surface of the bed, not placing all the strain on hips and lower back.

Another common concern seems to be heat retention in the mattress. This was a problem with earlier memory foam as they were designed in a closed cell, flat slab design that allowed no air flow. Now mid-layers are usually convoluted which allows air to circulate. Using a platform style slatted foundation can also improve air flow if that is a concern for you.

While no one mattress is going to satisfy everyone, the quick popularity and high satisfaction ratio combined with today’s lower prices certainly make it an option worth considering. Remember, 4 lb-6 lb densities are considered the best value and just make sure you have a return period if you are new to memory foam. Then, rest easy and enjoy the newest mattress technology!
