Memory Foam Mattress Reviews – High Resilience Mattresses
About Memory Foam
Memory foam, also known as visco-elastic polyurethane foam, was first used by NASA to ease the pressure put on the astronauts by the G-forces as they were pressed back into their seats. Memory foam helped their bodies get through the G-forces without developing pressure sores. After that, it was used in medical facilities, since the all-over support eliminates pressure-related bed sores. On today’s market you’ll find mattresses, mattress toppers and pillows made of memory foam.
How It works?
Memory foam works like this: at room temperature, the mattress is rather firm. Once a body is on it, the foam reacts to body temperature, molding itself to the shape of the body. This is what you see on TV all the time… a hand leaving a firm imprint on the memory foam. This attribute is actually why people like memory foam… because it molds to fit you; there are no uncomfortable pressure points on your hips and shoulders. Your entire body is supported equally. While memory foam mattresses may seem to be more expensive than standard innerspring mattresses, they have a much longer life.
Like any other product, there is the cream of the crop and low quality wannabes. When you go out to purchase a memory foam mattress, make sure you are getting a good quality mattress. Look for a foam density of around five pounds for the top layer. Anything less that this will not last long and won’t give you that memory foam comfort you want. Five pound density is what you will find if you go with the better known brands like Isotonic and Temper-Pedic. Next, make sure the core of the mattress is high resilience foam (HR). This foam is durable and comfortable.
While the density of the foam is what makes the memory foam so supportive and comfortable, it also makes for an extremely heavy mattress. Use caution when you are moving one so you don’t get injured. Another thing to take into consideration… some memory foam mattresses need to be aired to get rid of the chemical smell after manufacturing. Some people complain it smells like paint. Some are bothered more by this than others.
A definite plus for memory foam mattresses is that they seem to discourage dust mites and mildew, which may help if you suffer from asthma and other respiratory sensitivities. If you’re intrigued by the memory foam idea, but not sure how it will work for you, many of the more reputable companies will offer to send you a free sample, so you can see for yourself how it works. Others offer you a ninety day trial to use the mattress… and if you don’t like it, they’ll take it back.
Many mattress companies will offer you a waterproof cover to protect the foam of the mattress from sweat, incontinence and other sources of moisture. If the one you’re looking at does not, find one that does, or get your own cover. Keeping moisture away from the mattress is very important to maintaining its longevity.
