What was comfortable and supportive when you were 25 may not meet your needs when you're 35 or 45.

Don't look to the age of your mattress or the warranty to determine whether it's time for a new mattress. Neither are indicators of how long your mattress will maintain optimum comfort and support.
Proper care can extend the life of a mattress.
