What Are Memory Foam Mattresses Made Of?

Posted on

We’ve all heard of memory foam. But do you know what actually goes into a memory foam mattress?

From the different types of foam and their benefits to mattress construction, we take a look inside our mattresses to show you what a memory foam mattress is made of.


Memory Foam Material

What is memory foam and why is it so comfortable?

Memory foam is made up of the polymer polyurethane, which is combined with hard-working chemicals to give it its viscosity. This is what gives it that soft, sinking feel when you get into bed.

Upon contact with heat, memory foam softens and moulds to the shape of your body for individualised comfort and support. Then, when you get out of bed, the foam springs back to its original shape after a short period of time.


Is Polyurethane Foam the Same as Memory Foam?

No. Polyurethane foam or Poly-foam as it’s often called, is not the same as memory foam. The difference is that this type of foam is cheaper, and therefore lower in quality.

Like memory foam, poly-foam comes in varying densities, the higher the density the more durable the foam. It can provide a layer of cushioning but doesn’t have the same personalised support you get with memory foam.

You will most commonly see this material used in ‘egg crate’ style mattress toppers.


What is Reflex Foam?

Reflex foam is very similar to memory foam, it’s just constructed slightly differently. One difference is that it springs back into shape faster than its slower moving cousin. It’s also a little firmer than memory foam, making it a great base layer or component in supportive orthopedic mattresses.


What is Medical Grade Foam?

Medical or orthopedic memory foam is designed specifically for those who suffer from chronic back or joint pain. A network of grooves and channels carved strategically into the foam provide extra cushioning around joints and problem areas.


What Is The Difference Between Foam and Latex Mattresses?

Latex is created by connecting latex particles through heat and compression into a solid form. Mattresses can be made from both synthetic and natural latex.

Unlike memory foam, latex does not soften in contact with body heat and could feel too firm for some. However, it is a very durable material and natural latex has eco credentials.


Is A Hybrid Mattress Better Than Memory Foam?

Not necessarily. It depends on your sleeping style and preferences. A hybrid mattress combines several mattress features in one. Most commonly, spring mattresses are combined with a layer of memory foam for added comfort.

A hybrid mattress could solve a particular sleeping issue- such as getting too hot in the night, or if you and your partner have different mattress support needs.


Memory Foam Benefits

Memory foam beds can have a big impact on your sleep and spine health. Here are some of the benefits;

  • Cushions pressure points
  • High density foam prevents dust-mites from entering
  • Suitable for different body weights
  • Movement absorption minimises disturbance from your partners tossing and turning
  • Superior comfort and support
  • Long lasting and durable

Are There Any Disadvantages of Memory Foam Mattresses?

In the past, memory foam got some complaints for getting too hot in the night. While some, lower quality memory foam may not be suitable for hot sleepers, recent memory foam innovation has resolved this issue.

Here at Memory Foam Warehouse, we’ve come up with some intelligent solutions to combat the heat;

Our Coolmax mattress range features cooling fibres to help keep heat away from the body and washable covers to keep things fresh.

The 4G Aircool range of memory foam products are constructed through open cell technology. Air pockets in the foam allow better ventilation, helping you to sleep soundly, even when temperatures rise.
