Not sure if your mattress is past its prime? Our free Mattress Age Calculator analyzes your mattress type, age, and sleep symptoms to give you a personalized Mattress Health Score from 0 to 100.
Answer six quick questions below and find out whether your mattress still supports healthy sleep — or whether it is time to start shopping for a replacement.

How the Mattress Health Score Works
Your score starts at 100 and we subtract points based on two factors: mattress age relative to its expected lifespan, and the sleep symptoms you report.
Every mattress type has a different expected lifespan. Innerspring mattresses typically last about 7 years, memory foam around 8 years, hybrids about 9 years, and latex mattresses can last up to 12 years. For each year your mattress has exceeded its expected lifespan, we subtract 15 points from your score.
We also subtract points for physical symptoms: 20 points for visible sagging or body impressions, 15 points for waking up with back or neck pain, 15 points if you consistently sleep better in hotels or other beds, and 10 points for morning allergy symptoms that could indicate dust mite buildup.

What Your Score Means
80-100 (Green): Your mattress is still performing well. Keep using it and maintain it with regular rotation and a quality mattress protector.
50-79 (Yellow): Your mattress is starting to show its age. You have a year or two left, but now is a good time to start researching replacement options so you are ready when the time comes.
25-49 (Orange): Your mattress is past its prime and likely affecting your sleep quality. We recommend replacing it within the next few months. Check out our mattress finder quiz to find your perfect match.
0-24 (Red): Your mattress is actively hurting your sleep. Old, worn-out mattresses can cause back pain, poor sleep quality, and increased allergen exposure. Replacing it should be a priority.
Signs Your Mattress Needs Replacing
Beyond the age of your mattress, here are the key warning signs that it is time for a new one:
- Visible sagging or body impressions — If your mattress has a permanent dip where you sleep, it can no longer provide proper spinal alignment.
- Waking up stiff or sore — A mattress that causes pain is not doing its job. Your sleep surface should relieve pressure, not create it.
- Sleeping better elsewhere — If hotel beds or a guest room mattress feel noticeably better, your mattress has likely lost its comfort and support.
- Increased allergies — Older mattresses accumulate dust mites, dead skin cells, and other allergens that can trigger morning congestion and sneezing.
- Noisy springs — Creaking or squeaking when you move is a sign of worn-out internal components.

What to Look for in a Replacement Mattress
If your score suggests it is time for a new mattress, here is what to prioritize:
- Support and alignment — Look for a mattress that keeps your spine in a neutral position regardless of your sleep position.
- Quality materials — Higher-density foams and individually wrapped coils tend to last longer and perform better over time.
- Sleep trial — A generous sleep trial (at least 90 nights) lets you test the mattress in your own home.
- Warranty — A long warranty signals that the manufacturer stands behind its product.
