How Often Should You Replace a Mattress & Boxsprings?
-
New Bedding
-
A mattress and box spring set can be a big investment, both financially and for your well being. Your choice can set the stage for a good night's sleep or a fitful night of tossing. According to Bettersleep.org, the average life span of a set is between five and seven years.
Box Springs
-
While older mattresses often show signs of wear, including sagging in the middle, an older box spring, particularly one of good quality, can last longer. In some cases, unless you are purchasing a larger or heavier mattress such as a pillowtop, you may be safe to only replace the mattress.

Bottom Line
-
If your box spring and mattress set has been used regularly, particularly by more than one person at a time, your best bet for comfort and optimum sleep is to change out both pieces at least every seven years. For the best comfort, look for a mattress with at least 300 coils; the thicker the wire gauge, the longer it will last.
