Tempur Material vs Memory foam


Memory foam is a high-density foam that is predominantly used in mattresses and pillows. You’re probably thinking, well that’s not exactly rocket science, but you would be quite wrong…

TEMPUR® was first created by NASA in the 1970’s to cushion astronauts during lift-off as they journeyed into space. TEMPUR® sleep scientists realised the potential of this unique material and were the very first to introduce this revolutionary material to the world. Since then, we have been making mattresses and pillows with the aim of transforming the sleep of our owners across the globe.

We invest millions each year to constantly improve our formulas and innovate new products. In fact, only a handful of highly trained scientists know our secret formula!



Our unique TEMPUR® Material is composed of a secret formula, first developed by NASA scientists to support astronauts during lift-off.
1. ORDINARY SPRING MATTRESS - Lumps and bumps, Uneven pressure points, Bouncy 2. STANDARD MEMORY FOAM MATTRESS - Layers break down, More even pressure distribution, Motion transfer 3. TEMPUR® MATTRESS - 10 years of lasting quality, Absorbs and distributes pressure, Minimal motion transfer


TEMPUR® Material, composed of a secret formula and first developed by NASA to support astronauts during lift-off, provides support where you need it all night long.

When it comes to making mattresses and pillows, TEMPUR® is in a league of its own. For decades, competitors have attempted to replicate the unique TEMPUR® feeling. We have always manufactured our own products, while others frequently outsource their production which means they can struggle to monitor quality. We are the only mattress company in the world to be certified by the International Space Foundation!

Here are some reasons why TEMPUR® owners across Europe are more satisfied than owners of other mattress brands*

*Based on interviews conducted with over 37,000 mattress owners in 13 countries from 2014-15, where owners in each market rated TEMPUR® highest in satisfaction versus owners of other mattress brands.


enables our mattresses to absorb extra pressure. Effectively, TEMPUR® material redistributes your weight providing relief in painful areas of your body, ultimately allowing you to get a comfortable night’s sleep. We believe other types of memory foam and spring mattresses absorb less pressure which can cause an uncomfortable and restless night’s sleep..



It is our opinion that standard memory foam mattresses are not very effective when it comes to relieving pain and pressure. They have some pressure relieving capabilities but TEMPUR® material has been widely adopted in medical institutions across the world due to its proven pressure relieving properties. Based on our years of experience, TEMPUR® material has been found to alleviate tension in painful areas of the body whilst sleeping, allowing you to rest in complete comfort.


It has long been rumoured that standard memory foam can often cause a hot night’s sleep. This is because normal memory foam can have a dense cell structure which traps heat. However, TEMPUR® material has an open cell structure which allows the breathing of the material and heat to escape efficiently.


For spring and standard memory foam mattresses it can be very hard to clean them because often they come without covers which can be changed. However, every current TEMPUR® mattress is equipped with a removable washable cover which allows you to easily clean and refresh your bed!


Ordinary memory foam mattresses can often feel very firm to sleep on. This can cause discomfort and ultimately prevent you from getting a great night’s sleep. TEMPUR® material has been engineered to react to your body temperature. It is optimised to work best at room temperature (23°C). By actively conforming and adapting to your body shape you are constantly supported throughout the night. Furthermore, our wide range of mattresses means that you can choose a comfort level which is unique to you. View our full mattress range here.


Ordinary memory foam mattresses break down over time. This means their layers will start to crack and break open, ruining any support they provide. TEMPUR® mattresses offer a 10-year guarantee of lasting quality because we understand that a mattress is a long term investment for your health and well-being.


We know that TEMPUR is very different from the conventional products that are available today. So to help you decide if TEMPUR could be right for you, we've collected all of our most commonly asked questions together.

So, how does it work? What's it made from?

The TEMPUR pressure relieving material is composed of billions of visco-elastic spherical shaped, open cells. The cells respond to your body temperature and weight then shift and re-organise their position to mould to the exact contours of your body. It becomes softer in warmer areas (where your body is making the most contact with the surface) and remains firmer in cooler areas (where less body contact is being made). Due to the removal of pressure, blood is able to flow freely throughout the night, making you toss and turn less - in other words - you get a better night's sleep.

Is the TEMPUR mattress and pillow hypo-allergenic?

All products come with a cover that is antimicrobial treated for improved freshness and are hypoallergenic.

Won't it make me feel hot?

The TEMPUR material will not make you hot as it has an open ventilated cell structure. In a recent independent test designed to measure heat generated and retained during a seven-hour period, Ergonomie Institut München, proved TEMPUR beds sleep cooler than the similar products. This test involved measuring the two microclimatic parameters; ‘temperature’ and ‘humidity’, in the contact area between a climate dummy and bed surface.

After simulating 7 hours of sleep, repeated tests showed consistently a Rating 1, indicating Relative Humidity (RH) levels were below 50% and the TEMPUR material temperature was lower at 36.1°c.

Could I be allergic to TEMPUR?

Due to the special composition of the TEMPUR material, there is nothing indicating that our TEMPUR material should cause allergic reactions. TEMPUR material contains no common known allergens and should not worsen any allergy conditions.

Odor complaints:

Once unpacked, the product may give off a characteristic smell. This is completely harmless and disappears after a short period of use. To avoid this, ventilate the product before use.

I've seen references to NASA associated with TEMPUR. What's the connection?

The TEMPUR material was originally developed in the early 1970’s at NASA’s Ames Research Center, to relieve the pressure build up from the G-force experienced by astronauts during lift off. TEMPUR scientists realised the enormous potential of this material and began experiments in the early 1980’s to perfect it for consumer use. After millions of pounds in research, the TEMPUR Material we know today was perfected. As a result TEMPUR was presented with an award by NASA in May 1998.


Many people believe that waterbeds give you almost perfect support by allowing your body to ‘float’ in a natural position. In fact, due to displacement the waterbed creates what experts call the “hammock effect.” This is an unnatural and unhealthy curve of the spine resulting from improper support. The TEMPUR mattress allows your spine to rest in its natural position, giving you optimum sleeping posture and comfort.


Spring mattresses covered by quilted thickly padded ticking mean you are lying on row after row of coiled sprung metal. This often creates pressure points that can cause painful joints and an aching back The visco-elastic material in the TEMPUR mattress moulds to your body, adjusting to your body weight, and distributing it evenly, reducing pressure and providing maximum support.


Whilst individual pocketed springs will offer a higher level of support than innersprings, they are still restricted by the heavily padded ticking. The TEMPUR mattress is made from an open celled visco-elastic materials that moulds to the contours of the body, and is covered in a flexible cover.


Several copy visco mattresses are available today, but they are not visco elastic and do not have the 85kg density of the TEMPUR material or its durability of 15 years. The TEMPUR open cell visco-elastic material moulds to the exact contours of your body, giving you maximum support and pressure relief where you need it most.
