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

It depends on the type of mattress you have and how well-maintained it is. If your mattress is made of quality materials, then it should last for many years with regular maintenance and care. However, if your mattress has been exposed to moisture or dirt, or if you are not properly caring for it, then it may need replacing more frequently.
