How does memory foam work?

Just like most areas of life, the world of sleep technology has changed a lot in recent years, with one of the biggest advancements being the introduction of memory foam.

Available in mattresses, pillows and mattress toppers, memory foam is now a pretty common term in the world of bedding. But what exactly is it, how does it work, and how does it help you enjoy a better sleep?

Well, tuck yourself in and let’s turn the page on the story of memory foam…

What is memory foam?

In a nutshell, memory foam is a type of high-density foam that reacts to your body temperature to mould around it.

When pressure is removed, the foam returns to its original shape.

In the process, memory foam cushions your body to offer improved posture and a better sleep, and is also anti-microbial, which reduces common allergens like dust and mites.

A little history

One of the most fascinating facts about memory foam is that it owes its origins to NASA. First developed in 1966, it was initially called ‘spring back foam’ and was created to improve the safety of aircraft cushions.

After being released into the public domain in the 1980s, memory foam made its way into a whole host of products and industries.

For example, you’ll find memory foam used across the medical arena in beds that help prevent pressure sores, in wheelchair seat cushions, and also on X-Ray tables.

In sports, memory foam is used to line helmets, and in footwear it’s used for cushioning and comfort. You’ll also find it in furniture such as seating and sofas, along with the aviation and automobile industry for seat cushions.

By and large, however, the most popular use of memory foam is in bedding including pillows, mattresses and mattress toppers where it helps ensure a better night’s sleep

How it helps

When it comes to sleep, the major benefits of using memory foam include improved posture, improved comfort and reduced allergens.

Spinal alignment

As the foam moulds to your body, it allows you to enjoy a sleep position that offers better alignment for your spine.

Basically, the heat of your body allows you to soften the foam and sink in a little. In effect, that facilitates a sleep where the mattress or pillow is perfectly indented just to suit you.

Once you get up, the mattress or pillow returns to its original shape.

Reduced pain

The same principle helps ease the pain of aching joints. So, if you suffer arthritis or joint pain, memory foam helps cushion these areas.


It’s not the most pleasant of thoughts, but traditional pillows and mattresses have their fair share of allergens, including mites, dust and mould.

Due to memory foam’s dense structure and composition, it is resistant to these nasties, which can prove a game changer for people who suffer allergies.

Less partner disturbance

As much as you may love them, not all partners make for restful bedfellows. Memory foam can assist here as well, reducing the likelihood that you will wake to the disturbance of your partner moving.


Finally, memory foam is also incredibly durable, which could potentially increase the lifespan of your pillows, mattress or mattress topper.
