How Often Should You Replace Your Mattress?

Finding the right mattress is crucial because we spend a significant portion of our lives sleeping. A comfortable and supportive mattress is key to good rest, and when you finally find that perfect one, it’s an immense relief. However, as with all things, even the best mattresses eventually have to be replaced. So, how do you know when it’s time to say goodbye to your old mattress?

Let’s dive into the signs that indicate your mattress has reached the end of its lifespan. Keeping an eye on these red flags will make it easier to recognize when it’s time for an upgrade.

Signs You Need a New Mattress

Before checking for clear signs of mattress deterioration, consider how long you’ve had your mattress. The average mattress lasts between seven and ten years, so if yours is pushing past the decade mark, it’s likely time for a new one. Even if your mattress is closer to the seven-year mark, it might still be a good idea to start considering a replacement. Here are the key signs that it's time to shop for a new mattress.

1. Your Mattress Is Sagging

If your mattress shows visible signs of sagging, it’s a clear indicator that you might need a new one. Sagging can occur when the coils or memory foam inside the mattress start to lose their shape.

You’ll notice body impressions, especially if you’re heavier, leaving deep indentations where you sleep. If the mattress doesn't bounce back to a flat shape after you get up, it’s likely time for a new one.

2. Your Mattress Makes a Lot of Noise

Loud squeaks or screeches from your mattress could signal that it’s time for a replacement. This issue is common in coil mattresses, and while tightening any bolts may offer a temporary fix, the noise can also suggest that the coils are worn out and no longer provide the support they once did.

If the mattress is sagging and creaking, it might be failing to provide the support you need.

3. Your Mattress Has a Bad Smell

Over time, a mattress can start to develop unpleasant odors due to the buildup of mildew, mold, and bacteria, especially in humid climates. If you detect a musty smell, it may be time to get rid of the mattress.

4. Your Mattress Aggravates Your Allergies

A mattress can collect dust mites, mold, and mildew, all of which can trigger allergic reactions. If you regularly wake up with watery eyes, a runny nose, or headaches, allergens in your mattress might be to blame. You can consider mattresses that are designed to combat allergens, or use materials like latex and wool, which naturally resist allergen buildup.

5. You Wake Up in Pain

Waking up with aches and pains is a significant sign that your mattress may no longer be doing its job. Whether it’s neck pain, shoulder pain, or hip discomfort, a mattress that doesn’t relieve pressure points is likely to blame.

In particular, lower back pain is a common symptom of improper mattress support. Don’t ignore this issue—it’s essential to find a mattress that supports you properly.

6. You Can’t Get Comfortable

If you find yourself tossing and turning throughout the night, it’s a strong indication that your mattress has lost its comfort and support. If you frequently wake up feeling unrested, the mattress may be the root cause of your discomfort.

7. You Sleep Better on a Different Mattress

If you find that you sleep significantly better on a different mattress, such as at a hotel or a friend’s house, it could be a sign that your current mattress isn’t cutting it anymore. If you notice a reduction in symptoms like stuffy nose or joint pain when sleeping elsewhere, your mattress is likely responsible for your sleep troubles.

8. Your Sleeping Situation Has Changed

Even if your mattress still seems in good shape, changes in your lifestyle may warrant a replacement. Consider buying a new mattress if:

• Pregnancy has altered your sleeping needs.
• You’ve experienced significant weight loss or gain.
• You’ve gained a sleeping partner, and your old mattress no longer provides enough space or support.

Certain health conditions, such as arthritis or fibromyalgia, may also require a mattress that offers better pressure relief.

How to Make Your Mattress Last Longer

We’ve discussed when to replace your mattress, but there are also steps you can take to extend its lifespan. Consider these tips to get the most out of your mattress investment.

• Use a Mattress Protector: Protect your mattress from dust, mold, and mildew with a mattress protector. Some brands may even void your warranty if you don’t use one.
• Support Your Mattress Properly: Ensure your mattress is placed on the correct foundation, such as a platform bed or box spring, to prevent sagging.
• Avoid Jumping on the Bed: While it might be fun for kids, jumping on the bed can damage the foam and coils, reducing the mattress’s lifespan.
• Keep Pets Off the Bed: Pets bring dirt and pollen that can affect the mattress and reduce its durability.
• Don’t Eat in Bed: Eating in bed can lead to stains and attract bugs, such as bed bugs. Keep your mattress clean to prevent these issues.
• Clean and Vacuum Your Mattress: Spot-clean any stains promptly and vacuum your mattress a few times a year to remove dirt and debris.
• Rotate and Flip Your Mattress Regularly: For traditional spring mattresses, rotating or flipping your mattress regularly helps prevent body impressions and ensures even wear.
• Wrap Your Mattress for Moving: When moving your mattress, wrap it in plastic to protect it from dirt, allergens, and pests.

What to Look For in a New Mattress

If it’s time to replace your mattress, here are some factors to consider when buying a new one:

• Higher-Density Foam: Look for mattresses with a 4-5 lb density foam for durability. Foam with lower density breaks down faster, reducing mattress lifespan.
• Coil Mattresses: Coils can help prevent sagging and are a good choice for long-lasting mattresses.
• Sleeping Preferences: Choose a mattress that suits your sleeping position: Back sleepers: Look for a balance of comfort and support. Side sleepers: Go for a softer mattress to relieve pressure on the shoulders and hips. Stomach sleepers: Opt for a firmer mattress for support and spinal alignment.
• Back sleepers: Look for a balance of comfort and support.
• Side sleepers: Go for a softer mattress to relieve pressure on the shoulders and hips.
• Stomach sleepers: Opt for a firmer mattress for support and spinal alignment.
• Temperature: If you sleep hot, a hybrid mattress may be a good option since the coils allow for airflow. If you prefer an all-foam mattress, make sure it has cooling features.
• Size and Weight: Consider your body weight when selecting a mattress. Heavier sleepers may need a thicker comfort layer to avoid bottoming out.

Conclusion

Recognizing when it’s time to replace your mattress should be straightforward. Look for signs like sagging, pain, discomfort, and other issues. If in doubt, compare your current mattress with a newer one for a few nights to see if you experience a difference.

Before buying a new mattress, make sure to take steps to preserve your mattress for as long as possible, and consider the features that will best support your sleeping habits.
