What is the difference between memory foam mattresses?

The popularity of memory foam mattresses is relatively new. It’s easy to mistakenly believe that only one or two types are available. As with all products, there are many options for memory foam mattresses . There are low-quality, lower quality alternatives to high-quality, luxurious choices at the top end of the market.

As with all things, you get what your pay for. A memory foam mattress that appears too good to be true will almost always be inferior and poor quality. It won’t have genuine memory foam material and won’t offer the same performance as a premium product. You might not get what you pay for, even if you are purchasing the most expensive products. The price of mattresses and memory foam mattresses should not be taken into account when making a purchase decision. The offerings can be divided into three groups: lower-end, middle-range, and top-end.

Let’s look at the differences.

Lower end

A mattress can be considered an investment in your health in its most immediate sense. How you feel throughout the day and how healthy and well-rested your body are directly affected by how good or bad your nightly sleep. Consider how great you feel when you sleep well. Next, think about what happens if your night is not so good. It is easy to see the results in action. Poor sleep habits can cause insomnia and irritability. It can also lead to health problems that can last a lifetime, ranging from aches and discomforts to more serious conditions. The mattresses at the lower end are not as good as the high-end memory foam mattresses and can lead to poor sleep quality. Any minor savings you make by purchasing a memory foam mattress at a low price will soon lead to a loss in your daily feeling.

What are you really getting from these mattresses? There are many reasons these mattresses are so inexpensive, but the most important is the material they are made from. Most, if not all, of the mattresses in this category are made without memory foam, and many retailers use this term to mislead their customers. These mattresses, which are the cheapest, contain only a single-block of standard foam. This is not to be confused with memory foam mattresses.

These mattresses not only deliver sub-standard comfort and sleep quality, but they also have a very short life span . They will also deteriorate much faster than normal mattresses. These poor-quality mattresses not only deliver terrible performance , but they will get worse. A false economy is when you have to replace a mattress that’s cheap much sooner than one that can last longer. They can end up being quite expensive.

These mattresses are not recommended. These mattresses are often misrepresented as something they are not. They can be harmful to your health, could cause you to have a bad night’s sleep, and don’t last long. They are marketed as a cheap way to get memory foam comfort and low-cost, but they are quite the opposite.

Market in the middle-range

Although memory foam mattresses in the middle of the market contain some memory foam material, it is usually of such low density and height that it offers a sub-standard performance . These mattress types often claim that thicker memory foam layers will make the mattress more supportive. This false assumption is based on the fact that memory foam mattresses are relatively unfamiliar to the general public. A thick layer of memory foam, especially when combined with low-density materials, can create a soft, spongy, and comfortable environment for the sleeper. It may feel a bit more comfortable than a deep couch, but the memory foam feeling can make it uncomfortable to lie on a spring mattress. This does not provide body support and will likely lead to a sleepless night and morning of searching for the right position. A few nights of sleeping on a medium-range memory foam mattress can be a very unpleasant night-time workout for your body. It also results in poor sleep quality .

Low density materials, in addition to not being able to provide adequate support, also suffer from poor durability due to the movement within foam. The mattress can sag at the areas that are most weighted, especially under the hips or upper back. Low density foam has a larger cell structure which allows it to expand and contract more easily, creating softness. However, this also ages the memory foam faster than expected, resulting in inconsistent results after a short time. Even the initial softness of low density foam is lost. This leaves behind a very uncomfortable surface that you won’t like to sleep on.

The density ratings of memory foam (always refer to the memory foam layer and not the whole mattress) are determined by how much raw viscoelastic material was used in its manufacture. High density is represented by tightly packed cells and a stronger, supportive attribute. Low density is a less-constructed variety with more air cavities. The actual density rating is always expressed in a weight such as 50kg/m3. This is done by measuring the volume of memory foam material per cubic meter. This is why mattresses in the middle of the market cost less to make.

Although the technical specifications of memory foam mattresses will be better than those at the lowest end, they won’t offer the performance you expect. It’s clearly a false economy to select a mattress in this range. You’re choosing a product that will fail quickly and underperform right away.

The market’s top end

The best memory foam mattresses are made from premium materials with higher density. They tend to be composed of carefully layered combinations of components which combine to create a comfortable sleeping surface. There are many ways this can happen.

The visco-elastic layer of memory foam is cut to a optimal depth that both fits the body weight and the layers below it. With temperature-sensitivity, the memory foam shapes and moulds under the sleeper to create support where every part of the body is in contact with the mattress. This means that pressure points such as the hips, lower back and shoulders are provided with a consistent level of support and aren’t stressed throughout the night, as they would be with a soft or past-its-best mattress. The memory foam mattress creates a supportive, comfortable surface that allows the sleeper to quickly settle in to a comfortable position. This is much better than long periods of moving around to find the right position.

The visco-elastic memory foam that’s used in these mattresses is categorised as high density – HD – offering temperature-sensitive, pressure relieving performance for complete support, along with a longevity that low density alternatives can’t compete with. The other components of the top-quality memory foam mattresses include high-grade, high-density memory foam.

In most forms of memory foam, it is well-known that it has a high level of heat retention. This means that it can be’sleep hot’. The best mattress manufacturers recognize this problem and make sure that their mattresses are comfortable. The most common solutions are airflow layers embedded in the layered construction and ventilation-friendly covers. These considerations are absent in cheaper options, which makes them less competitive.

The memory foam mattresses at higher quality are generally more expensive than the lower quality ones. This is because they have better materials, better design, and a better ability to deliver great sleep. The benefits of choosing quality are immediately felt with great sleep, and all that goes with it night after night. These mattresses are also more durable than cheaper alternatives because of the better quality of the materials. The manufacturers are confident in their products and offer longer warranties and guarantees.


When you are weighing the options for memory foam mattresses, keep in mind the fact that there is a lot to choose from. Your sleep quality, as well as your overall health, will be affected by the choice you make .
