10 Fascinating Facts About Memory Foam

If you've been considering a new mattress and memory foam has caught your attention, it's time to find out more. We've collected ten fascinating facts so you can get your thoughts in order about this material – a little solid background helps before you buy, so you know what you're signing up for.

Online research generally breaks down into three forms: science, data and customer reviews. They all play a part, although some reviews aren't fully honest (paid reviewers write some, and others simply like to complain), so the science and data tend to be more reliable depending on the source. We've done some of that research for you, alongside our own years of experience with this foam. Here's what you need to know.

1. It adjusts to your body shape

The materials in memory foam are designed to change based on your body heat. Memory foam mattresses are so pliable that they mould around your body as you rest, actively distributing your weight. When you stand up, the mattress returns to its original shape.

2. It reduces allergens

Memory foam's density means allergens such as pet dander, dust mites and bed bugs can't find a hiding place. There's nowhere for dust and dander to collect, and the polyurethane fibres also deter allergens.

3. It's comfortable

People who sleep on memory foam report less discomfort and fewer aches and pains. A traditional mattress can put stress on pressure points, whereas memory foam supports your body evenly, removing that extra pressure on specific spots.

4. It doesn't transfer motion

If you don't sleep alone, a conventional mattress moves when someone gets out of bed. Memory foam is more solid and doesn't transfer motion, so even if your partner twists and turns all night, you won't feel it.

5. It's comfortable for side sleepers

Most people are side sleepers, yet most beds aren't designed for it. Memory foam supports your whole body and aligns with your hips and shoulders to give extra support with less pressure.

6. It was developed for NASA

Memory foam was originally developed for NASA to cushion landings. It was then used in hospitals for those on bed rest and in wheelchairs, so it had a long history of use long before it became a mattress material. See our other blog article on this.

7. It's non-toxic

Although memory foam is synthetic, it isn't harmful. The chemicals used are non-toxic to humans, so it's safe to use around babies, children and people of every age.

8. The new smell fades fast

Expect a strong smell when you first receive memory foam, but it soon goes. It's just the initial stage when the foam is fresh from the factory – there's no need to be concerned, as it's very safe.

9. It comes in a range of densities

Memory foam comes in various densities, but is generally far denser than a traditional mattress. When buying, pair it with a Coolmax cover to stay cool and comfortable even after movement.

10. It comes in different thicknesses

A thicker mattress will typically feel far softer than a thinner one.
