Outlast Mattress Technology

Outlast Logo

Outlast technology features in many of our mattresses and mattress toppers because it has so many amazing qualities to aid a comfortable night's sleep. This revolutionary technology was developed for NASA, so you know you're getting some seriously high-tech stuff if you buy a mattress with Outlast technology in it.

What is Outlast Technology?

Outlast technology was originally developed to protect astronauts from variations in temperature. It is a phase changing material that absorbs, stores and releases heat to give optimal comfort. As well as being used in the suits of astronauts, Outlast is now widely used in fabrics and fibres to help absorb the heat when the skin is hot and then release it when the skin cools again.

Outlast works by using patented micro-encapsulated Thermocules. These Thermocules continuously interact with your body to help balance your temperature and ensure that you don't get either too hot or too cold. The idea behind using the technology in mattresses is that your body will always be at the ideal temperature so that you can sleep comfortably.

How does it work?

Outlast technology works in a similar way to if you put ice into a drink to cool it down. As it turns to liquid, it cools the drink and absorbs the heat, keeping the drink at the ideal temperature. The Thermocules act in a similar way but they are incredibly durable so can be used in fabrics without difficulty.


When they're in a mattress, they absorb the heat coming off of the body, pulling the temperature down. However, once the body cools, the Outlast technology then releases that absorbed heat to warm the body again, ensuring a consistent, comfortable temperature is maintained.

The benefits of Outlast in a mattress

There are a number of key benefits to using Outlast technology, the primary one being its ability to maintain a constant temperature. The heat is stored, rather than removed so if you get too hot in bed, you will then be cooled down, without cooling to the point of feeling cold; the heat will be released before that happens.

Outlast works in a different way to traditional wicking technology. That method simply reacts to sweat and pulls it away from the skin. Outlast actually manages the heat as well as controls the production of moisture before it has even been created. This gives you the benefit of having a great night's sleep, without feeling uncomfortably hot or cold.

Having been used by NASA, Outlast boasts the Certified Space Technology seal of approval, making this material a sought after element to be added into all sorts of fabrics, particularly mattresses. The technology is constantly being developed as well, to ensure it continues to work in the best possible way.
