What Is A Memory Foam Mattress?
Have you ever heard of a memory foam mattress? Memory foam has in fact been around since 1966 when it was developed by a team of NASA scientists, who were looking for ways to make aircraft cushions safer. Therefore a memory foam mattress is a mattress manufactured from this space age foam, although modern memory foam has been hugely improved since those early days. The difficulty with the early foam was that it was too brittle, so it crumbled within a couple of years.
Nowadays, memory foam will conform to a body's shape by reacting to a combination of body weight and body heat depending on the density of the foam. One of the first uses of memory foam was in hospitals where it was found that memory foam could ease pressure on the parts of the body coming into contact with the foam, which reduced the occurrence of bed sores and gangrene in long-term bed-ridden patients.
The first memory foam mattresses were very costly and only institutions such as hospitals could afford them. However, over the last twenty years, the price of memory foam has fallen radically and so these super mattresses are now within the grasp of almost everyone who needs or wants them. There are options to the traditional memory foam mattress as well, there are memory foam pads and cushions and pillows too.
The use of this special foam has flooded into other areas of our lives as the price of it has dropped. Memory foam is now used in car seats, wheelchair seats, kids' high seats, earplugs, gloves and office furniture. In fact, this new foam is now used to produce many items that have to be worn or used for long periods of time - golf gloves too for instance.
Although the cost of these memory foam mattresses has dropped significantly they might still be too costly for everyone in large families to have one each. In this case you could go for mattress toppers which are otherwise called mattress pads. These are meant to be laid on top of the mattress but under the bottom sheet. They are less expensive because they are normally between two and four inches thick.
However, be cautious of cheap toppers because any foam memory foam topper that is thinner than two inches thick is prone to be useless. Likewise, bigger is not always better, because some individuals find memory mattresses that are over six inches thick are too hard to sleep on.
Check the warranty as well. Some high-density mattress pads of two inches thickness will crumble within a couple of years, so a two year guarantee means that you will get at least this length of time out of your memory foam mattress or mattress pad.
