The Outlast® Mattress Cover is designed to keep your body comfortable all night through the use of patented micro-encapsulated Thermocules™. This technology is designed to absorb and release heat dependent on your body temperature...not too hot…not too cold…just right®.

Research led to the use of 55 kg/m3 memory foam with the Perfect Mattress this density of foam was found to be ideal for back care and also not too dense so as to trap heat.

One of the properties of Memory Foam is reaction to heat from any source that is in contact with it. When Memory Foam heats up it expands and this can reduce the ability of the foam to ventilate air properly. If the density of the foam is too high this has the effect of reducing the size of the air holes within the foam structure, which can lead to heat getting trapped within the structure causing overheating.

Memory Foam Density is measured in kg/m3 . Simply put: If a sample of Memory Foam has a density of 50 kg/m3 a 1 metre cube of this sample would weigh 50kg. Memory Foam density can sometimes be used to determine the quality of the Memory Foam.

55 kg/m3 Memory Foam by itself would be too soft to make a 20cm mattress. Without a supportive core base layer a Memory Foam mattress is useless as you are likely to sink too far and find it difficult to be comfortable. This is why we use a comfort layer of 55kg/m3 on top of a supportive core base layer made of high quality PUI.

The PUI Base Layer has a channels running through it that improve ventilation and allow the mattress to deal with heat efficiently. These castellations are designed to channel heat away from top layer of the mattress and prevent the memory foam from overheating.

The combination of comfort and support found in our Perfect Mattress is what makes our mattress, well...perfect!
