This has all been crafted to enable you to have a superb night\'s sleep and let you wake up feeling refreshed. A Layer of Octaspring Foam Springs - These unique foam springs provide you with excellent support and comfort whilst the ventilation it offers helps you to have a fresher night\'s sleep. The two layers of Octaspring helps to distribute weight and correctly aligns your spine helping to enable you to fall asleep quicker and increase your time in a deeper sleep. Breathability - Octaspring has been proven to be 8 x more breathable than traditional memory foam mattresses. The unique Octaspring ventilation system provides a constant airflow. Your body movements push warm humid air out of the specially designed sides of the mattress, drawing fresh air back in, providing a fresh healthy sleeping surface night after night. 3 Zoned Body Support - Enjoy head-to-toe zonal support to provide you with total spinal and body support. The honeycomb springs are created in different strengths and densities and layered into body zones for your comfort. The mattress is firmer in areas where greater support is needed, such as the lumber region and softer in other areas surrounding the head, shoulders and legs. Memory Foam - Memory foam is an innovative material designed to shape itself to the contours of your body and then spring back into shape when pressure is released. Memory foam mattresses can offer valuable sleep support in a number of ways, such as enhancing circulation, equalizing pressure to relieve back problems, promote better spinal alignment, and reducing the effect of allergens for a fresher, healthier night\'s sleep. 360° Comfort - Octaspring performs like nothing else, hundreds of individual foam springs move three dimensionally cradling your body in complete comfort. Each individual Octaspring conforms to the contours and movements of your body in all sleeping positions reducing pressure points and promoting a healthy blood flow. No Transfer of Movement - Rest undisturbed. Memory foam greatly reduces motion transfer, so you won’t feel the other person in bed getting up or moving around.
