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.

The problem with low quality memory foam mattresses is because its made out of cheap materials. The memory foam is low density and is layered with other cheaper foam materials. It won’t last and this inexpensive material will give way and 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.

With a memory foam mattress topper, however, the comfort aspect is more important because when it wears out, it can easily be replaced. It will usually last 4 to 5 years at a 4 lb density rating. You want to make sure it is comfortable because you’re not buying the whole mattress.

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 in conclusion when you’re looking at memory foam mattresses, make sure you choose one that is 4 pound density for toppers or 3.2 to 3.4 lbs for the whole mattress.
