Replacing Your Mattress 101: How Often & How To Tell

Replacing Your Mattress 101: How Often & How To Tell

Figuring out when to replace a mattress isn’t always straightforward. People buy mattresses hoping they won’t need to replace them for years to come. 

Unfortunately, like any other piece of furniture, mattresses do not maintain their quality forever. At a certain point, they need to be replaced. This article will help you determine when that point may happen.

How long a mattress will last depends on its quality, warranty, and condition. If your mattress no longer feels good when you sleep on it, or you experience any of the signs mentioned in this article, it’s time to kick it to the curb. Read on as we delve into everything you should know about replacing an old mattress — and how SONU has your back.

How Old Is Your Mattress?

The average mattress should be replaced every 6 to 8 years. If your mattress is older than that, it’s probably time to invest in a new one. When you should replace your mattress depends on its condition.

SONU’s mattresses come with a 5-year limited warranty. These opulent mattresses are 14 inches thick and built to last for an extended period.

What Kind of Mattress Is It?

The material a mattress is made of is another way to determine if it’s time for it to go. If a mattress is well taken care of, then the following information will apply. 

Here are the recommended replacement times for each mattress material.

  • Memory foam: Replace every 10 to 15 years. The thicker the memory foam mattress, the longer it will last. 
  • Latex: Replace every 8 to 25 years. Latex lasts longer than other types of mattress materials. Many come with a 25-year warranty. 
  • Innerspring: Replace every 5.5 to 10 years. To increase the longevity of these mattresses, they should be flipped and rotated regularly.
  • Hybrid: Replace every 6 to 7.5 years. Foam and coil hybrid mattresses can last a while if they are high quality and well cared for.

Is Your Mattress Starting To Sag?

If a mattress is starting to sag around the corners or middle, it’s time for a new one. Low-quality mattresses are the most likely to start sagging over time. Body impressions may be left on the mattresses permanently if it’s time for them to be replaced.

Does the Mattress Show Signs of Wear and Tear?

In addition to sagging and body indentations, other signs of wear and tear mean it’s time to say goodbye to your mattress. If the bed has become lumpy, has tears in it, or is covered in stains, it’s best to get a new one. 

Are You Waking Up in Pain?

It’s time to let go of a mattress if it no longer supports you or you wake up in pain after sleeping on it. A mattress that is no longer comfortable to sleep on is not worth keeping around. Doing so for a prolonged period can cause issues with your spine, hips, and other joints.

Body pain isn’t the only way an old mattress can hurt you. You can develop allergies or asthma if you sleep on an old mattress. This is because allergens like mold and dust mites accumulate in a mattress over time.

Are You Getting Adequate Sleep?

Tossing and turning and disrupted sleep are sometimes signs that a mattress is not a good fit. If you notice that your sleep quality has declined since you acquired your mattress, then the type of mattress purchased is likely the culprit. 

If you are a side sleeper looking for a mattress with you in mind, SONU has you covered. SONU’s mattresses come with a patented Comfort Channel that allows side sleepers to place their arms and shoulders in it while they rest, alleviating pain from those areas. 

What Should I Look For in a New Mattress?

The task of finding a new mattress can be daunting. Especially if the mattress it’s replacing was used for a long time. While there might be a lot of things to consider when buying a new mattress, determining your must-haves should not be difficult.

Here are just a few things you should consider before buying your next mattress.

What Size Mattress Do You Need?

Whether you need a Queen or a Cali King, there’s a perfect mattress size just for you. Take into consideration how many people will be sleeping on the bed, body weight, and height. 

Best for…


Twin XL




Cali King

Single sleepers









More than two people



Lightweight sleepers




Heavyweight sleepers




Average height or below





Above average height



How Firm Do You Want Your Mattress?

To determine how firm a mattress should be, refer to the mattress comfort scale. This scale rates mattress levels Extra Soft through Extra Firm on a scale of one to 10. 

Softer mattresses are usually recommended for people who love to sink deeply into their mattresses. They provide a lot of pressure relief, so people with chronic pain issues may prefer them. They’re also ideal for light sleepers.

Medium and medium-firm mattresses are popular options that average sleepers choose. Medium is considered the “Goldilocks zone” because it is a suitable comfort level for all sleeping positions. There is just enough pressure relief and spine support to keep back-pain sufferers happy.

Firm mattresses are for people who prefer not to sink into their mattresses at all. They are great for people of heavier weights because they provide enough support without sinking. Although firm mattresses are too hard for some people, stomach sleepers might prefer them.

What Is Your Budget?

For many people, this is the most important consideration. Figuring out how much they can or want to spend on a new mattress can limit or increase sleepers' options. 

To save money, look for mattresses during holidays. A lot of mattress manufacturers run sales during those times. 

Look for companies that offer financing. Sometimes, great deals are available that help you purchase the mattress of your dreams via a low-interest payment plan.

If you want a high-quality mattress but are worried about the cost, SONU offers one of the most customer-friendly financing plans around. You pay $0 down and can make payments of $84/month with 0% APR for a period of 36 months. 

How Can I Make My Mattress Last Longer?

When you purchase a mattress, you want it to last you a good while. Taking care of your mattress by following a few, important steps will help extend its life.

  1. Use a mattress protector. Mattress protectors keep the surface of a mattress in good condition. They also protect the mattress from stains and allergens.
  2. Rotate the mattress. Rotating a mattress regularly will help it maintain its shape and “bounce.” After sleeping on a particular side for a few months, give it a break by flipping the mattress over and sleeping on the other side for a while.
  3. Vacuum and spot clean the mattress. As mentioned earlier, mattresses accumulate some not-so-great things, like dust mites. To help clean those up, vacuum the mattress from time to time. If there are any stains or discolorations on the mattress, spot-clean them with a stain-lifting product and a towel.
  4. Use a mattress topper. Like mattress protectors, toppers can keep unwanted stains and wear from affecting the mattress. Toppers can also serve as extra layers of cushion that make the bed more comfortable.

What Do I Do With My Old Mattress?

Some mattress companies, like SONU, will remove your old mattress for you when delivering your new one. This is called white-glove service.

You deserve to sleep on a bed made with quality materials that help you get rejuvenating sleep. SONU’s mattresses do that and more. When you purchase a SONU, you can rest assured that you’ve invested in one of the most durable mattresses on the market today. Even chiropractors recommend SONU.

If you purchased a new mattress from a company that doesn’t offer mattress removal service, it’s best to donate the old mattress or throw it away. There are even ways to recycle mattresses these days.


Replacing a mattress is a task people don’t look forward to, but it doesn’t have to be a pain. You first need to figure out when and why your mattress needs to be replaced. If it is showing wear and tear or meets any of the other criteria mentioned here, it’s probably time to go shopping.

Going to bed is the highlight of many people’s day. Coming home to a nice, top-of-the-line mattress that helps you stay asleep and provides pressure relief where you need it most is a dream that SONU can help you achieve.

Highly recommended!
I’m a side sleeper and I used to wake up with a dead feeling arm from lying on it all night. Finally a mattress with a pocket for my arm. I tried all the pillows and even very expensive mattresses in the past, but nothing cured my circulation problems until I got the sonu sleep mattress. I love it!
