The Dormeo Octaspring� 9500 mattress represents one of the most innovative and cutting-edge mattress designs on the market today. Not only do you have two dense layers of memory foam and latex to provide you with flawless cushioning and support, but the three layers of patented Octaspring� springs in different firmness ratings respond to your body weight and movement to give you a flawless night�s sleep.The design of the Octaspring� system means that air flows through it up to eight times more efficiently than through a normally constructed mattress. So even though you have those snuggly memory foam and latex layers, you�ll never get too hot and bothered. The Ecofresh treatment utilises naturally-produced probiotic ingredients that prevent the growth of bacteria and allergens, making this a great choice for asthmatics and those suffering from allergies.Dormeo�s patented and exclusive Octaspring� system is incredibly clever! Produced in different firmness ratings, the foam springs are carefully inserted into a matrix that gives varying degrees of firm and medium support to respond to your body�s movements. The Octaspring� 9500 has three layers of Octaspring� springs, providing unrivalled levels of cushioned support regardless of whether you sleep on your back, side, or your front.Latex has been used in mattresses for decades, thanks to its incredibly responsive properties and cushioning. The latex layer naturally contours to your body�s shape. This allows you to settle into a comfortable position and to stay there, minimising tossing and turning and giving you a more restful and undisturbed night�s sleep.To keep your sleeping environment clean, healthy, and smelling fresh, the super-soft Superstretch cover has a zipper that allows you to remove it and put it through the wash at 30�. Whereas most mattresses don�t have a removable cover, Dormeo has listened to its customers and created a cover that can be washed as often as you like.
