The human body naturally sweats to cool the skin, reducing the ability to keep the body dry and comfortable. This NASA developed technology, will keep you comfortable by absorbing body heat when too much is created, thereby reducing sweating.You'll have a great night sleep as the memory foam supports your body in just the right areas and the Outlast® controls your temperature so you're not too hot or too cold … just right™.

Other Memory Foam Mattresses Get Very Hot
Many people find that lying on our competitor's memory foam mattresses creates additional heat and increases sweating. This is due to memory foam heating up as a result of reacting to your body temperature.

SleepForm™ Keeps Your Ideal Temperature All Night
With SleepForm™you won't overheat and wake up sweating like other memory foam mattresses, due to the unique NASA endorsed temperature controlling cover, called Outlast®. This cover has the ability to keep the heat in the mattress as needed to maintain the supportive contours, yet you are kept at your optimal temperature throughout the night. So you're not too hot or too cold … just right™. Other mattresses including leading brands do not contain Outlast® and therefore can get very hot during the night.


  • Reduces overheating and night sweating
  • Provides thermal compatibility with your partner
  • Adapts to your thermal needs
  • Helps you to sleep more soundly

Outlast vs traditional products

Outlast® will help you sleep more soundly
Your body typically goes through several sleep cycles during the night, including the REM (Rapid Eye Movement) sleep. This is an essential part of the sleep cycle that is responsible for recharging and organising your brain for the next day.

Heat radiating from the body is trapped beneath the bed covers and can prevent your body from cooling down and allowing you to go into a restful sleep. Often you will toss and turn as your body search for the ideal temperature.

You are more likely to enter and keep in REM sleep when your body temperature is at a comfortable point. With an Outlast® cover on our mattress, it helps your body reach and comfortably maintain your optimum temperature for restful sleep. By eliminating temperature swings throughout the night, you are less likely to wake up from cold or overheating. The result is a deeper, more restful sleep. 

Outlast® Obtained the Prestigious Space Certification
Outlast® technology was originally developed for NASA. It was invented from the need to keep astronauts comfortable in space. It used in space suits and gloves to protect astronauts from extreme fluctuations between bitter cold and scorching heat that they experienced when in space or at the space stations.

The Space Foundations, a consumer awareness initiative supported by NASA and the aerospace industry, has designated Outlast® Technologies as ‘Certified Space Technology', visit www.spaceconnection.org/

What are Thermocules®?
Thermocules® are a patented phase change material that absorbs your body heat when you create too much and releases it when you need it most. This phase change take place in a very narrow temperature range equal to your ideal skin temperature and humidity. The result is a consistent microclimate next to your skin that keeps you comfortable.

What facts are there to support Outlast®?
Outlast® has obtained ASTM international certification, which successfully measured the effects of changing temperature on fabric with Outlast®ability to absorb, store and release energy in the form of heat. This effect can also be shown through Thermal Imaging camera visit www.outlast.com for more information.

What can I expect the first time I use Outlast®?
When you first lay down on our mattress with Outlast®, you will initially feel a slight cool sensation as the Outlast® bedding absorbs your body heat. It takes just a moment for Outlast® to adapt to your skin temperature.

Will adding a bottom sheet effect the benefit of Outlast®?
The Outlast® temperature controlling properties won't be effected by adding linen to your bedding. Place a bottom sheet over the mattress as you usually would. Do not use a mattress protector as these extra layers will effect the support given.

Where do I get more information on Outlast® technology?
Outlast® Technologies offers over 50 products containing phase-change Thermocules®, over 200 companies in outdoor sports, casual apparel, footwear, accessories and bedding use Outlast® materials in their products.
