Average Mattress Lifespan
Memory Foam Mattress: Ten years.
For durability, quality memory foam mattresses definitely beat other mattress types. Because of their packed construction and adaptable cells, memory foam mattresses can endure up to ten years of nightly use before they start to wear down.
Innerspring Mattress: Seven years.
Compared to memory foam mattresses, innerspring mattresses provide more of a tight ‘bounce,’ and, for some, higher feelings of support. Once an innerspring mattress starts to wear down, though (usually after seven years), it’s best to replace it as soon as possible, as even one broke spring can lead to loss of proper spinal alignment.
Hybrid Mattress: Eight to nine years.
If you prefer that distinctive ‘bounce’ of steel coils but wish innersprings would last as long as foam technology, then consider combining the two. With a lifespan of eight to nine years, hybrids deliver adaptive comfort and tight support – and fall right in between both mattress types in terms of durability.
Warning Signs that You Need a New Mattress
If your mattress is sagging, you notice dents or lopsidedness (especially in the center of the mattress, where you sleep) then it’s definitely time for a new one, as the lack of spinal support can lead to a host of orthopedic conditions.
2. Allergic reactions.
Along with spinal pain, an old mattress can also trigger or intensify allergic reactions. Over time, your mattress can accumulate dust, mildew and other allergens – and negatively affect overall health.
3. Joint pain.
Waking up with sore muscles, a stiff back and/or joint pain or weakness is another sign that the innerspring or foam cells are starting to break down and not providing the proper spinal support.
