When To Replace Crib Mattress | Guide

When to replace crib mattress? This is the most common question on which many parents don’t focus. However, it’s necessary to replace the crib mattress after it becomes old and uncomfortable for your baby. 

The perfect baby crib mattress is a coveted and often-purchased item. But, unfortunately, the quality of these mattresses can vary depending on where they were made. Which in turn affects their shelf life.

You’ve spent months picking out your favorite design for an affordable price only to find it. When it comes time to buy one that’s been manufactured overseas without any environmental standards or regulations put into place during production.

Not only does this mean lower durability. But also possible harmful chemicals getting into contact with your child (if there aren’t proper separation distances set between machines). Did you know that it’s possible to reuse your baby equipment? 

This is especially true for second-hand crib mattresses and clothes. Or if one might be getting another child soon after their first. Then, you can cut expenses by using these items again instead of purchasing new ones for newborn #2.

The reality is you have to replace the crib mattress sometimes, but this depends on the individual factors. For example, a mattress that has been properly cared for can last up to ten years before needing repairs or an upgrade.

However, there may be some wear-and-tear as it is constantly handled roughly. When slept upon by young children who are learning how to walk and talk at different ages.

In this article, we are going to discuss and everything about toddler mattress. What signs indicate that it’s time to replace crib mattress, and how can you increase the longevity of your baby’s crib mattress?

So without wasting further time, let’s solve this enigma to know when to replace the crib mattress.


Below given signs gives you a signal that now you need to replace the crib mattressOtherwise, your baby can’t feel comfortable while lying on it. And sometimes, it can be quite dangerous and unsafe for your baby.

Less Firmness

The first and easiest sign is the firmness of your baby’s crib mattress. If it becomes too old, you will notice that its springs lose their tension, leading to severe injuries for children. They sleep in this type of bed as they grow up much faster than adults do. With mature bones that need skeletal support. 

That’s why every good parent wants nothing less than soft mattresses. So our toddler doesn’t end up sleeping on concrete bricks or something equally harmful. Ironic though because those same types wouldn’t offer enough cushioning anyway.

When babies lie down on their bellies, you want a surface that will bounce back immediately after they stop pressing. This way, the baby can’t sink into it and potentially suffocate or be in danger of rolling over onto its side due to being crooked. 

When awake because they could hurt not only them. But also other people around who may step on an uneven floor. While trying to help out with whatever needs doing at that moment.

Double-sided mattresses provide a soft and comfortable surface for children of all ages. However, if you notice that one side is much softer than the other, then your mattress needs to be replaced. Because this could mean that it has lost its ability or capacity to support body weight evenly across both sides after time takes its toll on aging bodies.

A test for one-sided mattresses is checking to see if they are firm or soft. It would be best if you pressed down on it quickly with your finger. So that you can tell whether the bed will bounce back immediately. Even though there may be some time needed before getting into its original shape again. Because this poses a risk using them.


Firmness and consistency are both crucial for great sleep. Tight areas of the mattress should be checked to ensure they’re straight; while not as important, innerspring beds may have some valleys or indentations resulting from natural wear-and-tear over time.

This can cause problems with comfort if left unchecked. When you find a flaw in your mattress, don’t just think about the potential for suffocation or injury. Babies move around quite often! It’s not wise to count on them rolling far enough down. 

So that they won’t be able to breathe through any holes created by these flaws (even if only one side has anything wrong with it).

Sterile Surface

If you notice any stains on the mattress of your crib, then surely replace the crib mattress. Babies are susceptible to their surroundings at this age and will feel anything off-putting in their environment.

Even if they can’t talk yet! So make sure there are no remnants or spills from food products. Before placing the baby into their own little space for sleep time adventures tomorrow night.

Babies need to be exposed to various organisms for their immune systems to develop appropriately and stay strong. So if your baby stays on one dirty bed all day. You may produce an effect crashing its defense with dirt and germs that are lurking around everywhere.

Crib mattresses are essential to your baby’s safety, but they can pose a severe risk if not cleaned properly. This is because stains and residue often form or attract mildew, which attracts more dirt than you may think- fungus, mold, germs, etc. 

These things will interfere with respiration causing allergies as well difficulty when breathing. There’s no way of doing proper crib mattress deep cleaning. That’s why replacing crib mattresses is a better and safer option.


The best way to avoid your baby’s risk of ingesting anything harmful is by making sure they are always covered up during sleep. Exposure risks increase exponentially when infants have loose threads, fabric rips, or even minor cuts on their mattresses where dirt and other materials could be pulled into these openings. 

Which would pose an inhalation hazard as well since babies often suck on fingers while crying in distress after waking from sleeping too profoundly without protection against drafts under furniture pieces near cribs–a habit now both causes mattress wear-and-tear due to natural inflammation caused by skin obstruction (choking). 

Kids can also pull on the filling and cause damage to a mattress, which is not easy to fix. You may patch up minor cuts in your bedding. But it’s best if you play things safe by throwing out anything that has been severely ripped or punctured when necessary because these types of incidents will only get worse over time without intervention from an expert professional.


The life span of a crib mattress is usually limited to about three years, but you can make it last longer by following these simple tips. So you don’t need to replace the crib mattress too early for your purchase.

Use Covers And Sheets

You might be surprised to know that there are mattresses with double or even triple-reinforced layers of coverings. These types of sheets can last for years before they show any sign of wear and tear, making them very durable.

If your current set is too thin and you notice an area where the material isn’t as thick as expected, consider upgrading the soft fabric into more substantial.

Keep Extra Baby Cloth

Another thing to consider is always having a baby cloth in your crib while your child is still very young. Vomit, pee, and poop slips are pretty standard even during sleep-time, which can lead to unpleasant odor and stains on their mattresses that may take hours or days before they go away completely.

Waterproof sheets have been around for years as an affordable solution/transition option; however, this would mean sacrificing comfort. So it’s best to do without them if possible unless you’re willing to spend extra money where it matters most.

Avoid Heat Sources

Babies are small, lightweight creatures who can’t regulate their body temperature – which means you need to take caution when touching a hot surface. In addition, metal cribs should never be left near any heat source because they will bend and warp faster than other materials.

Even if the mattress isn’t directly exposed, it’s still at risk of being weakened by this increased temperature along with carbon-monoxide buildup due to these escaping fumes trapped inside your home.

Store Mattress Properly

This is not at all unusual. Moisture and insects can get into a mattress even if it’s stored in the basement. So you should first keep away your old ones properly with plastic wrap or cardboard boxes before putting them where they will stay dry- vacuum sealing works too. 

When checking for signs of insect bites, make sure to check covers as well because sometimes those pesky bugs find their way onto fabric surfaces close by spots on bed springs which could lead some people back from getting bitten again.


Most crib mattresses are built to last five years. However, some claim they stay for longer. Be aware of the five-year rule in your mind, and lower the number of years if your bed has had a complicated life. You can raise it if you’ve been vigilant with your care.
