Adults place a high value on their own beds. We spend a lot of time researching the comfort, longevity, firmness, and cooling of a mattress or pillow. In addition, we want the finest value for our money. Even more careful consideration should be given to our child’s mattress, especially when it comes to a crib. The safety of your infant or toddler is equally as vital as their comfort, so don’t forget that. Aside from the obvious questions of whether or not you’ll be able to use the bed in the future if you have another child, you may also wonder if you may accept a hand-me-down from a generous family member or friend. How long do crib mattresses last? And other related questions will be addressed in this post.

Baby Beds Lifespan Factors


Your baby’s mattress’s lifespan will greatly rely on the sort of material it is made of, such as memory foam or innerspring. It’s not uncommon for memory foam to fail over time, especially if its density is low. Discrepancies in shape and support are more likely when the density of the foam is reduced, hence indentations are more likely. Suffocation is a real danger to an infant if there is an indentation in the skin. When it comes to mattresses, innerspring coil structure tends to endure longer, regardless of whether the mattress is for an adult or a baby. Over time, they can break through. It’s time to get rid of it when this happens.

When purchasing a crib mattress, keep in mind the material the cover is composed of. Material and construction are two of the most important factors in determining the bed’s longevity. Thin covers, such as vinyl, will eventually lose their structural integrity. Look for a ticker that is constructed of nylon, which is a robust material.

Waterproof Capacity

Unfortunately, accidents do occur. Quite a bit. Blood, vomit spit, pee, blowouts, and drool all have the potential to impair the mattress’ life expectancy. Mold, mildew, and dangerous germs can grow and fester if a liquid soaks in. Stains also violate the manufacturer’s warranty. The lifespan of a waterproof mattress is far greater than that of a non-waterproof mattress. A protection or a separate pad can be purchased if yours is not.

Stain Resistance

Stains will void your guarantee, therefore a stain-resistant material is perfect for extending its lifespan. Some are pre-treated to resist stains. Your mattress may need to be cleaned more frequently if it isn’t waterproof, therefore you’ll need to use a waterproof mattress cover.

Care and Maintenance

Taking care of your crib mattress now can help it endure longer in the long run. The following are the top three suggestions for you:

  1. As soon as an accident occurs, clean it up immediately. Don’t allow them to soak up all the moisture in the bed.
  2. Consider purchasing a cover to keep liquids from spilling or leaking out.
  3. Prevent the accumulation of any undesirable objects or creatures by routinely inspecting and cleaning your mattress (like dust mites).

You can help your bed last for years by following these three simple actions.


Proper storage is critical whether you plan to use it for a second kid or give it away to someone else. Avoid placing the bed near a sink or other wet areas. Also avoid direct sunshine and heat, which will weaken the material’s structural integrity. Store it in its original box or in a plastic wrap to keep it dry and at room temperature.

Is it Still Safe to Use?


In order for the bed to be secure, it must nevertheless feel substantial to the touch. Babies, in particular, are exempt from this regulation. Getting smothered by a surface that is excessively soft puts them at risk of becoming immobilized. Sudden Infant Death Syndrome is more likely as a result of this (SIDS). A toddler bed doesn’t need to be as solid as a full-size bed, but it still needs to be comfortable. It is common for cot mattresses to have dual-sided: one that is firm for infants and one that is softer for toddlers. See if there is a visible difference in the firmness of the two sides of the bed.


There should be no indentations in this bed if it is intended for a baby. It’s time for a new mattress if you feel your body sinking into a particular section of the old one. Again, indentations pose a safety risk to babies who are unable to move or roll on their own at this time. They pose a significant risk of asphyxia.

Loose Threads

Make sure there are no missing stitches. Putting them in your baby’s mouth or pulling on them can put them at risk for choking. There is a risk of exposure of filler or other materials, as well as choking, as they unravel. An old mattress with loose threads is a sure sign that it’s time to replace it.

Harmful Pathogens

You may be exposed to hazardous microorganisms if your bed is old or hasn’t been properly cared for.. In addition to bacteria and fungi, the list also includes mold, mildew, and algae. Having these in the home raises the risk of respiratory issues, such as allergies and asthma, for infants and toddlers. Because of the difficulty breathing, there may be an increased risk of SIDS.

Foam crib mattresses

Polyurethane, a foam resin or composite, is commonly used to make memory foam mattresses. When compared to other types of mattresses, foam ones are often more cheap.

There are numerous health and safety concerns with memory foam mattresses for babies, including the increased risk of suffocation and Sudden Infant Death Syndrome (SIDS). Please keep this in mind before purchasing one (SIDS).

Make sure you try out the foam crib mattress before you buy it, even if you decide against it. If you press on the foam with your hand, time how long it takes for it to return to its original shape. Your child’s safety is at risk if the structure is unable to recover rapidly, which indicates that it lacks the necessary resiliency.

Memory foam mattresses with a higher density are also better for babies because they are firmer. Using your hand, feel out the density of a mattress (mattresses with high densities are usually heavier).

Innerspring crib mattresses

In terms of “conventional” mattresses, innerspring mattresses are the most popular. Steel coils inside give them their well-known toughness and pliability.

Additional comfort is provided by innerspring mattresses that include polyester, foam and cotton blends.

If you want to know how long an innerspring mattress will last and how thick its steel coils are, you need to look at its coil count and steel gauge. Choosing thicker gauges and higher coil counts is the greatest option because they provide the most support and are more likely to survive a long time.

It’s worth the money to get an innerspring mattress for your infant, despite the higher price tag, to ensure that they enjoy a decent night’s sleep.

Double-sided mattresses

As previously said, some crib mattresses are meant to grow with the child.

The harder side of a double-sided mattress is designed for infants, while the softer side is made for toddlers.

Changing a child’s mattress is as simple as flipping it over. Dual-firmness mattresses, like their innerspring counterparts, are fantastic for lasting the test of time, but they can be a little pricey.

Sponge or foam can be exposed when threads are unraveled, and this could be dangerous. A new, stain-resistant and waterproof cover can be readily installed if the sponge is in good condition.

Frequently Asked Questions

Would you recommend buying a used mattress?

This isn’t a good idea in general. Because it’s unlikely you’ll come across an unblemished old mattress, you should steer clear of any mattress with a stain on it. A stain could be lying beneath the surface, even though it’s not visible to the naked eye. As the new owner, you don’t know what kind of adventures this bed had prior to your arrival.

Should you buy a new mattress for your second baby?

How you cared for it with your first child and how long you used it will determine the answer to this question. This crib may still have some life remaining in it if it was well-maintained and the baby was moved to a new bed during the first three to five years of life. It may be time for something different, though, if your first child had many accidents that weren’t cleaned up right away, and they spent lots of time jumping and bouncing on the surface.

Are firm mattresses or soft mattresses better for a baby?

Babies require a firm mattress to support their skeleton, prevent asphyxia, and much more. SIDS is more likely to occur on a mattress that is too soft. Check out here and this for more information on this topic.

What purpose does a crib mattress pad serve?

Your baby will benefit from the added comfort of a mattress pad as well as the added protection it provides against spills and stains, which could extend the life of the mattress itself.

Size is the most significant difference between the two. While a regular crib is 28 inches broad and 52 inches long, the width and length of a tiny crib are 24 and 38 inches respectively. Although a newborn can sleep in a conventional crib, it’s just not as comfy, thus a small cot is better suited for a younger child.

Is It OK (And Safe) To Reuse A Crib Mattress, Such As An Old One?

If you’re a parent, this is a no. Nevertheless, if it’s a crib mattress that you’ve taken good care of and haven’t used in the preceding three years, there’s a good chance that you can use it again.

If you saw that your child was frequently jumping on the mattress as they grew bigger and more active, it may be time to buy a new one!
