How do I know if I need to buy a new mattress? 

A mattress has an average lifespan of 6 to 8 years. However, if you feel that your mattress is not providing you with sufficient comfort and support, or notice a sag in your mattress, then you should consider buying a new mattress. Waking up with aches and joint pains is also an indication that you probably need a new mattress.
