How to Tell If Your Mattress Needs Replacing (Before It Wrecks Your Sleep)

How long have you had your mattress? It might feel like you bought it just a couple of years ago, but time passes quickly. The mattress that once felt soft and supportive might now be making it harder for you to sleep well.

Take a moment to think about this.

Do you wake up feeling tired, sore, or stiff?

Are your allergies acting up more than usual?

Does your mattress look saggy or worn out?

If you answered yes to any of these questions, your mattress might no longer be giving you the support and comfort you need. In this guide, we will go over when to replace your mattress, what signs to look for, and how to take care of it to improve your sleep.

How Often to Change the Mattress?

Mattress Type	Lifespan
Memory Foam	Longer-lasting than traditional options, lasts around 10-12 years.
Innerspring	Around 10 years
Hybrid	Generally durable, lasts around 7-10 years
Latex	Up to 15 years
Adjustable	Depends on construction and materials, lasts around 6-8 years
Orthopedic	Depends on materials used, lifespan can range between 8-12 years

Factors that Influence the Lifespan of Your Mattress

A mattress is not something you replace often, so it helps to know what affects its lifespan. Some mattresses stay comfortable for years, while others wear out sooner. Here are a few things that can make a difference.

1. Quality of Materials

   Not all mattresses are built the same. Higher-quality materials like durable foam, strong coils, and breathable fabrics hold up better over time. If a mattress is made with cheaper materials, it might start sagging or losing support much sooner. That’s why buying from a trusted brand like Flo, which focuses on quality, can make a big difference in how long your mattress stays comfortable.

2. Care and Maintenance

   How you take care of your mattress affects its lifespan. Regular cleaning, rotating it every few months, and following the manufacturer’s care instructions can keep it in good condition. A waterproof mattress protector helps prevent spills, stains, and dust buildup, which can break down materials over time. Adding a mattress pad can also help protect it from wear and tear while making your sleep more comfortable.

3. Kids and Pets

   A mattress will last longer when it’s only used under normal conditions. If kids or pets regularly sleep on it, the chances of spills, stains, and damage go up. Jumping, scratching, and chewing (hopefully just from pets) can break down the materials faster, leading to early wear.

4. Weight and Body Pressure

   More weight on a mattress means more pressure on the springs and foam. Heavier sleepers might notice sagging or a "hammock effect" sooner than lighter sleepers. Using a supportive bed frame and choosing a mattress designed for heavier weight can help slow down this process.

When to Replace the Mattress?

A good mattress plays a huge role in sleep quality and overall health. If your mattress is old or worn out, it can cause discomfort and affect how well you rest. Here are some signs that it might be time to replace your mattress.

1. Waking Up with Aches and Pains

   If you start your day with back, neck, or shoulder pain, your mattress may no longer be supporting your body properly. Over time, mattresses lose their ability to keep your spine aligned, which can lead to discomfort. If the pain disappears when sleeping elsewhere, it’s likely that your mattress is the issue. Getting a mattress that suits your sleeping position can make a big difference in how well you rest.

2. Sagging or Uneven Surface

   A mattress that has visible dips, lumps, or sagging areas is no longer providing the right support. Memory foam can lose its shape, and spring mattresses can wear out, making sleep uncomfortable. If your mattress is not keeping its original form, it is time to consider replacing it for a better night’s rest.

3. Noisy Springs and Creaking Sounds

   Hearing squeaks and creaks when you move is a sign that the springs inside are worn out. A mattress should allow you to shift positions quietly, without disturbing your sleep. If the noise is becoming a regular issue, upgrading to a new mattress will help improve comfort and reduce disturbances.

4. Allergies Getting Worse at Night

   Dust mites, pet dander, and mold can build up inside a mattress over time. If you notice your allergies or asthma symptoms getting worse at night, your mattress might be the cause. Cleaning your mattress regularly can help, but if allergies persist, consider replacing it with a fresh one.

5. More Than 7-10 Years Old

   Even a well-maintained mattress should be replaced after seven to ten years. Over time, the materials break down, making it less comfortable and supportive. You spend a third of your life sleeping, so upgrading your mattress after a decade is a smart choice for better rest.

6. Your Partner’s Movements Wake You Up

   If your sleep is disturbed every time your partner moves, your mattress might not be absorbing motion well. Older mattresses tend to transfer movement more, making it harder to sleep peacefully. Newer mattresses are designed to reduce motion transfer so both you and your partner can rest undisturbed.

7. Constant Tossing and Turning

   If you struggle to find a comfortable position and constantly toss and turn, your mattress might not be supporting your body properly. A worn-out mattress can make it harder to settle in and fall asleep. Upgrading to a mattress that suits your sleeping style can make a big difference in your rest.

8. Sleeping Better on Other Beds

   Do you sleep better at hotels or on other beds than your own? If you wake up feeling more refreshed after sleeping away from home, it’s a clear sign your mattress isn’t providing the comfort and support you need anymore.

9. Bad Smell That Won’t Go Away

   Over time, sweat, moisture, and bacteria can build up in your mattress, leading to unpleasant smells. If your mattress still smells even after cleaning, it might be time to replace it. A fresh, odour-free bed is important for a clean and healthy sleeping environment.

10. Body Impressions Stay on the Surface

    A good mattress should return to its original shape after you get up. If it stays indented for long periods, the materials inside have likely worn out. This means the mattress is no longer supporting your body the way it should. If your bed has permanent dips and impressions, it is time to replace it for a better sleep experience.

What to Consider When Buying a New Mattress

Getting the right mattress can make a big difference in how well you sleep. It’s not just about comfort but also about proper support for your body. Here’s what to think about before making a choice.

1. Pick a Mattress That Matches Your Sleeping Position

   The way you sleep should guide your decision. Different sleep positions need different types of support to keep your spine aligned and prevent discomfort.

   • If you sleep on your back, a medium-firm to firm mattress is a good choice. It keeps your spine straight and prevents back pain.
   • If you sleep on your side, go for a softer mattress. It cushions your shoulders and hips, reducing pressure on these areas.
   • If you sleep on your stomach, a firmer mattress is better. It stops your lower back from sinking too much, which can cause discomfort.

   Choosing the right firmness level helps improve sleep quality and prevents aches in the morning.

2. Check for Motion Control and Durability

   If you share your bed, a mattress with motion isolation is a good choice. This prevents movement from disturbing your sleep when your partner turns or gets up. Memory foam and hybrid mattresses are known for absorbing motion well. Durability is just as important. A well-made mattress lasts longer, so investing in a quality one means better sleep and fewer replacements over time.

3. Look for a Trial Period and Warranty

   Since a mattress is a long-term purchase, it’s best to test it before making a final decision. Brands like Flo Mattress offer trial periods of at least 100 nights so you can see if the mattress is comfortable for you. Warranty is another thing to check. A longer warranty means better protection for your purchase.

How Can You Make New Mattress Last Longer?

1. Use a Strong Bed Frame

   A sturdy bed frame or box spring gives your mattress proper support and prevents sagging. Weak support can lead to uneven wear and reduce comfort over time.

2. Let It Air Out Occasionally

   Moisture can build up inside the mattress over time. Every now and then, remove the sheets and let it breathe for a few hours. This helps prevent mold and keeps your mattress fresh.

3. Rotate It Regularly

   Most mattresses should be rotated every few months to prevent sagging and ensure even wear. Foam or latex mattresses usually need to be rotated every 6 to 12 months, while innerspring mattresses should be rotated every 2 to 6 months. Some modern mattresses don’t need rotation, so check the manufacturer’s instructions before doing so.

4. Keep Bedding Clean

   Washing your sheets every week and your comforter every few weeks keeps dirt, sweat, and dust mites from settling into your mattress. Regular cleaning also helps prevent odours and moisture buildup.

5. Use a Mattress Protector

   A mattress cover acts as a barrier against spills, stains, sweat, and dust mites. Choose a washable, water-resistant, or waterproof protector to keep your mattress in good condition.

6. Vacuum and Deodorise Your Mattress

   Dust and debris collect over time, so vacuuming your mattress every few months can help keep it clean. Sprinkling a little baking soda on the surface before vacuuming helps absorb odours and moisture.

7. Make Sure Your Mattress Has the Right Support

   Not all mattresses work with every type of base. Innerspring mattresses usually need a box spring, while foam, hybrid, and latex mattresses work best with slatted or solid foundations. Using the wrong support can lead to uneven wear and discomfort.

8. Protect It from Damage

   Jumping on the bed may be fun, but it puts extra stress on the mattress and weakens its structure over time. If you have pets, keep their claws and teeth away from the mattress to avoid rips and scratches.

Final Thoughts: Invest in Better Sleep

Your mattress plays a major role in your sleep quality and overall well-being. If you’ve noticed discomfort, sagging, or allergy symptoms worsening, it might be time for an upgrade. Choosing the right mattress can improve your sleep, reduce aches, and boost your daily energy levels. By maintaining it properly, you can also extend its lifespan and get the best value for your investment.

A well-rested you is a healthier, happier you—so don’t ignore the signs. When it’s time for a change, pick a mattress that truly supports your comfort and long-term health.

Frequently Asked Questions about When to Replace Your Mattress

1. Is a mattress still good after 20 years?

   No, a mattress shouldn’t be used for that long. Even if it lasts, using the same mattress for 20 years can lead to discomfort and health issues. Most experts recommend replacing it every 10 years to ensure proper support and hygiene. Over time, mattresses collect dust, allergens, and lose their shape, affecting sleep quality.

2. How often should you replace your pillow?

   Pillows should be replaced every one to two years, depending on their material and how well they are maintained. Over time, pillows lose their ability to provide proper neck and head support, which can lead to discomfort and poor sleep. Regular replacement also helps prevent the buildup of dust mites and allergens, keeping your sleep environment clean.

3. What are the symptoms of a toxic mattress?

   A toxic mattress can cause headaches, skin irritation, breathing problems, and a strong chemical smell that doesn’t go away. Some mattresses release harmful chemicals, especially when they are new. If you wake up with allergy-like symptoms, dizziness, or feel unwell after sleeping, your mattress could be the problem. Choosing mattresses with natural or certified non-toxic materials can help avoid these issues.

4. What type of mattress is healthiest?

   The healthiest mattress is one that provides proper spinal support, reduces pressure points, and is made from safe materials. Organic latex, memory foam with low chemical emissions, and hybrid mattresses with natural fibres are good options. A mattress should also be breathable and resistant to dust mites and allergens for a cleaner sleeping environment.

5. What is the most comfortable mattress?

   The most comfortable mattress depends on personal preference, body type, and sleeping position. Memory foam mattresses offer great pressure relief, while hybrid mattresses combine foam and coils for a balance of support and softness. If you prefer a softer feel, a plush top layer can add extra comfort. Trying out different types or choosing a mattress with an adjustable firmness level can help find the perfect fit.
