Account
Generally speaking, memory foam is manufactured from polyurethane and chemicals that increases both its viscosity level and density. Its other name, at least amongst the technically correct, is visco elastic polyurethane foam. (Better stick to its popular name. You can't be saying that mouthful when you are shopping for it)
There are two types of the mattress. First, the higher density memory foam moulds itself to your body shape because it reacts with your body heat. Of course, you have to lie in the memory foam mattress for a few minutes to make an impression on it. Second, the lower density foam quickly moulds to your body. Even a simple hand pressure will leave an imprint!
Also, the density affects the firmness level of the memory foam. It will be firmer in cooler temperatures and softer in warmer temperatures, which means that your memory foam experience will differ according to the prevailing season.
And don't worry about the mattress looking like an alien thing. It looks just like any other mattress except for the feel and the smell.
Benefits
There are two main benefits to be had from the right type of memory foam mattress. First, since it moulds to the shape of your body, you are provided with the right support on strategic body parts. The most important, of course, is your spine that retains its proper alignment.
In essence, you have a measure of protection against diseases brought by unnatural spine alignment caused by improper posture, either awake or asleep. Plus, the mattress provide for comfortable sleeping, which means that you wake up with less back ache, hip pain and even shoulder cramps! And you should know by now how important sleep and waking up in a good mood are to your general health.
Second, the memory foam mattress is not as conducive to dust mites and mildew as an ordinary mattress due to its denseness. This is good news for asthma sufferers and others who suffer from respiratory disorders.
However, before buying said mattress, it is always best to do a comparison shopping. You want a high quality mattress without the high cost.
Concerns
On the minus side, for some, memory foam mattresses give off a distinct smell akin to newly applied strong paint. Although said smell can be reduced by frequent airing and use, you may remain sensitive to it. As such, your memory foam mattress can cause more respiratory problems that offset the benefits it may have for you.
Also, you must never place infants and toddlers in it because of safety concerns. Since it readily moulds itself to body shape, it can cause suffocation on infants with no muscle control. And don't forget that it can be combustible so don't light up anywhere near it!
In conclusion, memory foam mattresses have great health benefits for users. However, like most consumer products, certain precautions must be adapted to fully enjoy said benefits.
