I've heard that it is important to get a new mattress every five years. Is that true?

That depends on the type of mattress you have and how often you use it. If you are sleeping on an innerspring mattress, then yes, it is recommended to replace it every 5-7 years. However, if you are using a foam or latex mattress, then it may be more beneficial to change them after 3-5 years.
