Dynamic Thermoregulation with Outlast Technology

Maintaining a consistent body temperature is critical for good uninterrupted sleep.
We all have different core temperatures and personal preferences, so utilising a dynamic material that changes with us (and our sleep environment), is really important. Outlast reacts to your body, absorbing and releasing body heat, thus smoothing your temperature fluctations: a dynamic temperature 'buffer' between you and your mattress to aid your sleep. Best of all it reacts to you as an individual so is the perfect solution when sharing a bed.
Why not improve thermoregulating performance by accompanying this product with one of our exclusive Outlast duvets? See our duvets section for more information.

There is a lot of terminology banded around regarding the 'allergen' performance of mattresses. What we know is this: dust mites like to live in warm dark places, in moisture filled, closed environments. Latex mattresses afford no such opportunity, and neither do truly ventilated mattresses. Hypo-allergenic means 'less allergen likely than others', which is the truth of the matter and why we use that statement for mattresses to which it applies. In addition to a materials specific properties and the ventilation of mattresses to reduce allergens, most of our mattresses also have removable washable covers, which is a significant step in terms of being able to regularly wash away any dust, skin cells or allergens that are either airborne or may accumulate through your use of the bed.

outlast temp regulating

Outlast is patented 'Certified Space Technology™'. It utilises encapsulated 'Thermolecules' to absorb your body heat, in what is a known as 'phase change material'. In doing so, it reduces your bodies natural response to heat - to sweat, and rather than wicking it away, it takes heat away from the skin surface to address sweating and therefore moisture build up before it occurs. Thereafter, the phase change thermolecues release the heat when your body temperature drops. The result is less sweating, less moisture, and a smoothed median night time temperature, that adapts to the individual underneath it. A true Sleep Engineering solution that we are delighted to present in our most premium quilts.

total ventilation

Good ventilation is at the heart of healthy revitalising sleep. Where we mark our products as 'total ventilation' it indicates that every aspect of the product has been considered with ventilation in mind, and therefore every material, surface, and construction has been provided with total breathability and complete airflow. Not only is total ventilation the easiest way to regulate temperature, but it is also the best way to decrease microbial/allergen/dust/mites activity.
