Hypnos is continually looking at new ways to improve the comfort and support of our beds in order to create the ultimate sleeping experience, as a result we do make changes to our Collections. It is probable that if your mattress is over 5 years old then this exact model will no longer be available, but a similar, comparable bed will be available. Your retailer will be able to guide you through our current Collections and help you find the best bed from our current range which is best suited to your comfort and support needs.
