Nowadays, there are many memory foam manufacturers and there are many types of memory foam out there. This increases selection but there have also been some low quality products out on the market. This is bound to happen because of competition and manufacturers trying to hit all the consumer price points.It may seem like a good deal to buy a discount memory foam mattress but you really get what you pay for. In the case of the cheaper mattresses, the quality of the materials are evident and the lower density foams are used in conjunction with other cheaper materials. The mattress will wear out fast.So what should you be aware of? It really depends on what you're going for. Generally you can get a whole memory foam mattress bed or you can get a memory foam mattress topper which is basically a layer of memory foam which goes on top of your existing bed. Suffice to say, the whole bed version is a lot more expensive and your concern should be comfort and durability.The main concern with the topper version is comfort because it can easily be replaced. Replacing it is easy since it just sits on top of your existing mattress. It will last approximately four to five years if its about four pound density.When you buy a memory foam mattress or pad, you have to be aware of the density of the memory foam. No matter what the sales person says, here's what you have to keep in mind. It costs more to make denser foam simply because of the materials going into it but denser foam does not necessarily mean more comfort.All that density means is how much the foam weighs. So a 3 pound desnity foam simply means that a cubic foot of foam would weigh 3 pounds. A cubic foot is measured by one foot in length, width and height.Furthermore, denser foams tend to have more of that unique memory foam mattress feeling. The feeling of it conforming to your body and giving way to your weight. The less dense foams don't have enough thickness and support to provide this feeling.So when you are looking to buy a memory foam mattress, the ideal density is really 4 pounds for mattress topper pads and 3.2 to 3.4 pounds for less dense foams. Be a conscious shopper and do you homework before you arrive at the mattress store!If you enjoyed this article, be sure to check out my other work.
