A memory foam mattress is one that combines springs or support foam with a memory foam surface. These mattresses are so popular because not only does it provide soft comfort but also because of its high energy absorption capabilities. With the warmth and pressure from the body, it molds to provide superior support to the sleeper

Traditional memory foam is designed to comfort your body while you’re sleeping. It helps increase the circulation of blood and reduces the amount of stress you have on specific joints or pressure points, depending on your sleeping position. And thanks to the materials used and its design, a traditional memory foam mattress will last much longer than a springform


Gel memory foam is a memory foam infused with gel, which also has two different types – The liquid memory foam and gel enhanced memory foam. The first is a type of material that absorbs heat. You can think of it as an ice-pack in your refrigerator. The other type is what is known as a phase-changing material. What this stuff does is to help regulate your temperature when sleeping by heat absorption and release

2. When are they best used?

IIn the medical field, memory foam was used throughout hospital intensive care units and in wheelchair seat cushions to support, secure, and comfort individuals. The memory foam’s pressure-relieving properties have been used to help prevent pressure sores and relieve discomfort in sensitive areas.

3. When was it first introduced? 

In the mid-1960s, NASA initially designed memory foam, also known as visco-elastic foam. The memory foam is made of polyurethane to counteract the extreme pressure astronauts faced as they enter and exit the atmosphere on the Earth. Memory foam has been used in a variety of other products – now most popularly in mattresses, pillows, and mattress tops.

5. How to use it?

Since a memory foam mattress isn’t waterproof, you can prolong the longevity of it by using a mattress protector. It is designed to ensure that you keep the mattress as clean as possible. It also reduces the abrasion of the surface caused by the movement of the body.

6. Cost?

Usually, you can measure the value of foam mattresses by their strength, density of the foam, and type of foam. If brands use more polyfoam in their foam mattress, it will be cheaper. The use of exceptional foams, such as silicon or copper-infused, generally costs a little more.

A foam mattress can cost more than R5999 or less, but be cautious of cheaper models – at first, they may feel like a great value buy but most lower-density foams run the risk of degrading more rapidly.

7. Lifespan

A memory foam mattress’s lifespan may vary depending on how you use it and the quality of the memory foam. A memory foam mattress can survive the seven-year lifespan suggested by The Sleep Council.

However, for hygiene reasons, we suggest that you replace your memory foam mattress every seven years. Although dust mites are unable to penetrate the framework of a memory foam mattress, they can grow on your mattress surface over seven years. Renewing your bed every seven years will maintain a clean, fresh, and hygienic sleeping environment.

We recommend using a mattress protector to help extend your mattress life and help keep dust mites at bay.

8. Pros and Cons


Uses Your Heat

One of the significant advantages of solid memory foam is that it can use your heat and body pressure to mold exactly to your shape. Here is what comes to play with the “Visco” part of viscoelastic. The memory foam is further softened by the body heat, making it more viscous. That’s what makes you want to dive into it. The foam bounces back to how it was when you get up from the bed. That’ll be the “elastic” part. It is also good to support your body’s alignment. It is suitable for your spine to sleep on a natural curve as well as promotes lumbar support.

Relieves Pain

A great thing about memory foam is that it is also useful in relieving the discomfort in pressurized areas. Those beds can provide relief if you have joint pain.

Great for Those with Allergies

This is the advantage of looking for a hypoallergenic memory foam. The structure is very dense and is suitable for reducing the number of allergens it can accumulate. Dust, mold, and other allergens will not find a way into your bed.


Heavy Weight

Dense foam can be an asset, as well as an annoyance. The weight of the mattress makes it very heavy and difficult to be moved. It means that it may not be possible for one person alone to set up the bed initially. Lifting it to place sheets below could also prove to be a problem if you try to do it on your own.

Becomes Too Hot

Another downside is that the foam beds are known to retain heat. This could mean some uncomfortable during the warm months. 

By selecting the right type of memory foam, you can combat it. If you’ve noticed that you’re getting warm using standard memory foam, you’ll want either open-cell memory foam or gel-infused memory foam. These mattresses are all designed to be more breathable and expel unnecessary heat.

Not Waterproof

Foam mattresses and toppers do not do well with humidity. You should be very careful to avoid the contact of your bed with continuous exposure to moisture. It can worsen mattress degeneration and decrease its usable life.
