10 Signs That You Need to Replace Your Mattress

Last Updated on 21 October 2025

A good night’s sleep is essential for your overall health and how well you rest. A restful mattress is a major factor in each of these. Even the best-quality mattresses don’t last forever. It can affect your sleep, posture, and even overall well-being.

Most mattresses last between 7–10 years, but depending on usage and quality yours may need to be replaced earlier. Here are 10 signs it’s time to replace your mattress.

1. Visible Sagging

If your mattress has large indentations, lumps or sagging proportions, it is no longer supporting your body as necessary. Sagging puts strain on the muscles and spine leads to aches in bad sleep quality. Mattresses at Bedworld do not have problems of sagging and will help to minimize your back pain also.

2. You Wake Up with Pain

Morning stiffness, sore backs, or neck pains can be caused by an old mattress. When a bed loses its ability to support natural spinal alignment your body compensates by sleeping in uncomfortable positions.

3. Enhanced Allergies or Asthma

Old mattresses pick up dust mites, allergens, and even mold over time. If you find your allergies get worse at night, or when you wake up, it may be down to what’s growing in it rather than to the air inside.

4. Noisy Springs

If every time you move you hear a squeak or creak, the inside coils of your mattress are gone. This is the condition older innerspring models tend to develop and hints that it’s time for replacement.

5. Trouble Sleeping

Struggling to fall asleep or stay asleep may not always be due to stress. If you toss and turn because you can’t find a comfortable position, trusting your mattress may be reaching the end of its useful life.

6. Sleep Better Elsewhere

Have you noticed that in a hotel bed or lying back on your pillow in the living room you always sleep better? That’s a clue your mattress at home is no longer doing the job.

7. Your Mattress Is Over 7–10 Years Old

While some mattresses may last longer, the general lifespan is around 7–10 years. Materials break down naturally over time, even with good care, so if yours is pushing a decade, it’s time to start shopping.

8. You See or Smell Signs of Wear

Stains, mildew odors, or fabric tears are all indications that a mattress is past its prime. Nasty as they are in themselves, these signs of wear can also trigger health problems and make you restless at night.

9. Sleeping Partners Disturb Each Other

If you share a bed and feel every movement your partner makes, your mattress has likely lost its ability to absorb motion. A new mattress with better motion isolation can make a huge difference.

10. Your Body Has Changed

Weight shifts, injuries, pregnancy, or aging can all change what you need from a mattress. If your present one no longer meets your needs for comfort or support, put it away and buy a new one that will allow you to both sleep more comfortably and with less trouble from aches and pains.
