All products come with a five-year guarantee meaning you can be secure in the knowledge that your bed is designed with longevity in mind. Most mattresses are replaced between 8-12 years, yet often, people do not change their bed base at the same time. While there is no fixed rule about when to change your bed, it is important to consider that your bed base undergoes the same amount of stress as a mattress. Therefore, changing your base at the same time as your mattress will ensure that your new mattress and base fit together perfectly and help you achieve a great night’s sleep.
