Best Mini Crib Mattresses For Your Baby

A baby in the house means tons of diaper changes and lots of sleepless nights for you. But no matter your exhaustion, you always want your baby to have the best nights sleep. This, of course, depends on the crib mattress.

If you’ve chosen a best mini crib for your little one instead of the standard size – you are not alone. After all, a smaller crib takes less space, is more affordable, and with the right mattress, provides the same comfort as the standard size.

The key term here: “Right†mattress.

Remember, choosing the best crib mattress for your newborn is crucial. Too soft and you could risk the baby sinking in. Too small and the baby could hurt themselves in the space between the crib and mattress. But do not worry. Whether first-time parents or otherwise, it is common to feel overwhelmed with the baby crib mattress choices in the market. Our guide will help you make an informed decision.

Would you rather invest in a mattress cover that you could throw in the wash and clean effortlessly or be scrubbing for hours to get the stain off your baby’s mattress? The former definitely seems like a better option.

How To Choose A Mini Crib Mattress?

Choosing the best crib mattress for infants is not just a question of what looks better or feels cheaper. Babies have requirements that change with time, and since they will be sleeping for most hours of the day initially, getting a mattress that fulfills them is important.

Know the dimensions of the crib 

The usual, large-sized cribs have standardized specs. They are 52×24 inches. A mini crib, on the other hand, can be any size. Really. 

Before you begin shopping for a mattress, measure your crib. They are usually 24×38 inches in size, but it’s better to double-check. 

Then, make sure to buy a mini mattress that’s a snug fit for your crib to ensure less than 2 finger space between the crib and mattress. Any more, and your child can be at risk of SIDS. 

Go extra-firm

Newborns and infants need a flat, rigid surface to sleep on. If you’ve got any extra pillows surrounding them, or a mattress that is too soft, your baby can sink in the plushness and suffocate. 

Therefore, choosing an extra-firm mini crib mattress for the initial years is the way to go.

You can also buy a dual-sided mattress that is firm and infant-friendly on one side, and soft and toddler-friendly on the other. Simply flip it when your child grows. 

Prioritize breathability 

Your little ones, no matter how little, are often fond of rolling over. This could be in their sleep, or otherwise. 

If you are not present to bring them to their original position at the time, it can become a problem. In such situations, having a breathable mini mattress for the crib pays well.

You can sleep well at night, assured that even if your baby decides on a different sleeping position, all will be well.

Do not compromise on safety

As parents, we can be willing to compromise on ourselves. But when the matter includes the safety of our child, it stands above all. This is why it becomes important to choose a baby crib mattress that meets FDA requirements and comes with the best certifications. 

Some of those include the Greenguard Gold certificate and the Certi-PUR US. 

Prefer to buy a new mini mattress for the crib 

This is important. Many people might suggest thrifting a mattress or using an old one. We wouldn’t do that.

Over time, mattresses can build bacteria, germs, and all kinds of bugs. The springs can sag, the foam can sink, or a multitude of other problems can occur. You shouldn’t take that chance with your little one, especially when their immune systems are barely developed, and their little bodies are so vulnerable. 

Our list of picks includes many budget-friendly options too. So, instead of thrifting or recycling a mini crib mattress, choose one of them instead!

10 Best Mini Mattress For Crib 

Now that you know the criteria of the best mattress for your baby’s crib, it’s time to get the recommendations rolling. 

Out of the many mini crib mattresses that we’ve come across, these were the best in terms of, well, everything. 

Have a look!

Dream on Me Portable Foam Mattress

1. Best Flippable Mini Crib Mattress: Dream on Me Portable Foam Mattress

Priced at just a little above $50, this mattress is a complete winner. For starters, it’s exactly 24×38 inches, the usual size for mini cribs. So, you know it’ll be a snug fit. 

The mattress comes with 2-sided foam, and one is firmer than the other. Therefore, this budget-friendly mattress also works long-term.

Simply flip it over when your newborn grows into a toddler and use the soft side instead. In addition, since the material is foam, even if your crib is slightly smaller, let’s say one inch, this could probably bend and take its shape while leaving no dangerous space for your little one. 

Being Greenguard Gold certified, the mini mattress ensures low chemical emissions and therefore upholds breathability and child safety. 

The mattress also comes with soft vinyl, waterproof cover that is easy to clean and perfect for the accidental spills and leakages that are bound to happen. However, it can be a little noisy when the infant moves. So, the mattress isn’t exactly the quietest.

  • Dual-Sided
  • Waterproof
  • Hypoallergenic
  • Greenguard Gold Certified 
  • Can be a little noisy

Babyletto PURE CORE Mini Hybrid Mattress

2. Best Waterproof Mini Crib Mattress: Babyletto PURE CORE Mini Hybrid Mattress

Since we’re talking about leakages and wee-wees in the night, of course, our next pick refers to a mini crib mattress with impeccable water-resistant qualities. 

Not only is this Greenguard Gold certified mattress waterproof, but it also comes with a removable, water-resistant cover. The cover has a quilted cotton face and is PVC-free. This means it’s soft to the touch and prevents any liquids from reaching the core of the mattress.

The mattress is also lightweight and firm, just what you’d want your child’s mattress to be. Weighing at merely 4 pounds, you can insert it in the mini-crib or use it for a child’s playdate – everything works! 

  • Waterproof core and cover
  • Zipper closure and snug fit
  • Greenguard Gold Certified 
  • Lightweight    
  • Does not use organic materials
  • Relatively expensive 

DaVinci Complete Slumber Mini Crib Mattress

3. Best Lightweight Mini Crib Mattress: DaVinci Complete Slumber Mini Crib Mattress

Lifting mattresses isn’t easy on the back and considering how mini crib mattresses need to be transported from one room and crib to another, as well as washed or flipped, it’s better if they are lightweight. Fortunately, we found one that is just that, at a mere 3.75 pounds! 

The DaVinci Complete Slumber is unbelievably light, making it easy for parents to change the sheets. But not that you’d need to, because it also comes with an easy-clean, waterproof cover. 

There are air vents on the sides of the mattress that make it breathable and hypoallergenic. Combined with its high standards of testing (as many as 10,000 chemicals!), the mattress is also safe for your child. What more could a parent want?

But wait, there is more! The mattress, unlike most in the market, is also pretty quiet. The cover is non-crinkly along with being tear-resistant, allowing your child to enjoy uninterrupted sleep for long. 

The only downside: the dimensions aren’t an exact standard replica. They’re roughly 37x24x4.5 inches, so they can turn out to be a tight fit for your mini crib.

  • Lightweight
  • Waterproof cover
  • Greenguard Gold Certified
  • Quiet
  • Dimensions different from the standard

LA Baby 3†Mini /Portable Crib Mattress Pad

4. Best Multipurpose Mini Crib Mattress: LA Baby 3†Mini /Portable Crib Mattress Pad

As a parent, you want your child to have the full experience. Stay in the crib, play in the outdoors, both. This multipurpose mini crib mattress by LA Baby helps you achieve this and more. 

The mattress is quite firm with a Polyester Foam core in the standard mini crib size. This takes away any worries of the wrong crib fit and ensures safety in your child’s sleep.

But in the day, this lightweight mattress can be picked and hauled outside like a pack ‘n’ play. Its outer cover is laminated waterproof and completely stain resistant. So, your child can have a stack of markers, a spill of food, or the usual drool, and nothing would happen to the mattress. In case it feels dirty, you can wash the cover easily with mild soap and water.  

However, this one’s not the quietest mattress in the lot. Therefore, if your baby moves a lot during sleep, the crinkly cover can cause a little problem.

  • Easy to clean
  • Lightweight
  • Waterproof
  • Portable
  • The crinkly cover is noisy

Newton Baby Mini Crib Mattress

5. Best Breathable Mini Crib Mattress: Newton Baby Mini Crib Mattress

When considering crib mattresses, Newton Baby shines with its breathable category. Fortunately, we found that in addition to a standard-sized baby crib mattress, the company also produces a mini one – yay!

Perfect for babies who tend to sleep on their stomachs or face-down, the mattress features a distinct breathe-thru technology.

Its core is made with 90% air and 10% food-grade polymer, in addition to a 100% breathable and washable cover.

What’s better is that its 2-stage. With a stiff and soft side, you can simply flip the mattress according to your baby’s needs, making this a good, long-term investment.   

This mattress is also perhaps one of the only few ones that come pediatrician recommended too! The level of firmness is just right for babies and helps in their musculoskeletal development – an important aspect for babies in the infancy stage.

While this mattress does sound too good to be true, there is just one little thing. Some consumers have complained of a slight smell upon arrival, so bear that in mind.

  • 100% Breathe-Thru technology
  • Washable
  • Greenguard Gold certified
  • Pediatrician recommended 
  • Known to have a slight smell when it arrives

Wonder Buggy’s Wonder Dream

6. Best Safe Mini Crib Mattress: Wonder Buggy’s Wonder Dream

In their newborn and infancy stage, babies do not have a fully developed immune system. Therefore, the responsibility of protecting them from all kinds of toxins and infections comes on to the parents. By purchasing a safe, hygienic, eco-friendly crib mattress, you can put those worries at rest. 

The Wonder Dream is just as its name entails – a complete wonder. Yes, it might not be the cheapest or lightest mattress in the market, but its vast array of qualities outshine its limited cons. 

To begin with, the mini crib mattress is 100% breathable. It helps regulate the temperature of your child, preventing those disturbing sweats or extreme coldness in the middle of the night. 

The cotton cover is also completely non-toxic and hypoallergenic. There is no foam, no off-gassing, no harmful emissions, or anything that could challenge your baby’s health really. 

Another major plus point: it’s the perfect size for mini and portable cribs! With the mattress dimensions at 38x24x5 inches, it’s exactly the standard mini crib size and deep enough to avoid requiring another mattress or crib mattress topper.

  • Greenguard Gold certified
  • Non-toxic
  • Hypoallergenic
  • Water repellent 
  • A heavy mattress option weighing 9.08 pounds
  • Slightly expensive 

Moonlight Slumber Baby Bluebird Mini 5â€

7. Best Thick Mini Crib Mattress: Moonlight Slumber Baby Bluebird Mini 5â€

If you want a mattress that does not require a pad or topper above, this one by Moonlight Slumber is the perfect match. With a plush and firm side, the mattress isn’t just two-faced, it grows with your child without requiring any replacement until your little one grows out of their toddler stage. 

The mattress is 5 inches thick, instead of the usual 3 inches mini crib mattresses you’ll come across. The firmer foam density means better support for your child and their development throughout the years. It also means this mattress can be slept on or used as a heavy play pad. 

Another aspect that impressed us was the luxurious material. Made with a 30% organic, lush cotton cover and invisible stitching, the mattress not only looks good – it feels good! If we could have a mini-turned-adult-sized mattress for us, it would probably be this one. 

With a removable cover, the mattress is also stain, water, and odor resistant. Gone through a diaper leak in the night? Afraid your child might spit up in the crib? No problem. Zip the cover open, put it in the wash, and zip it up again for a snuggly fit. 

Of course, all of this comes at a slightly higher price (about north of $170), but it’s a long-term investment, isn’t it?

  • Made with Tencel, eucalyptus-based fibers  
  • Waterproof
  • Irritant-free
  • Doesn’t lose shape in the wash   
  • Comparatively expensive 

Nook Sleep Organic Mini Crib Mattress

8. Best Organic Mini Crib Mattress: Nook Sleep Organic Mini Crib Mattress

The Nook Sleep Organic Mattress is 3 inches thick. Which means it isn’t as thick as the Baby Bluebird. But users say it feels pretty dense and plush. 

This isn’t what impressed us though. It is what was inside the mini crib mattress that made us term it as one of the best ones.

The mattress is Greenguard Gold certified and its core materials include organic coconut coir and organic wool. This makes the surface extra-firm (just perfect for babies!) and beautifully textured, just like a cloud. 

Speaking of clouds, the mattress also comes in two shades: Blush and Cloud. The freedom of colors also made us happy. After all, parents do long for an aesthetic, colorful room for their children, and what better way to do it than by beginning with the crib mattress?

The product also comes with a removable mattress cover that’s easy to wash. Albeit it is not the standard dimensions you would imagine. The mattress is sized at 37x23x3 inches (i.e., about an inch less than the standard mini crib size) so you should measure your baby’s crib before purchasing to ensure a perfect fit.

  • Meets Global Organic Texture Standard Guidelines
  • Greenguard Gold certified
  • Machine washable
  • Multiple colors available
  • Slightly less than the usual mini crib size
  • Expensive

Delta Children Mini Twinkle Stars

9. Best Recycled Mini Crib Mattress: Delta Children Mini Twinkle Stars

What if we told you there is a way you can ensure comfortable sleep for your child while not compromising on sustainability – at all? This mini crib mattress rendition by Delta Children is the ultimate answer. 

Eco-friendly to its core – quite literally – the mattress features a center created from upcycled plastic bottles.

These form a premium, sustainably sourced fiber that not only adds firmness to the mattress but also keeps it toxins-free and away from harmful chemicals. 

While your child sleeps soundly at night, you can rest assured that they’re not breathing in anything dangerous. 

The mattress is also hypoallergenic and incredibly easy to clean. It has a waterproof vinyl cover that can be wiped clean with a little soap and water. While the mattress itself is so lightweight that changing sheets and swapping bedding feels like a breeze. 

There are two depth sizes in the mattress: 3 and 4 inches. This is a quality seldom found in brands and makes this an excellent option for those who need a portable mattress or one that fits comfortably into their baby’s crib.

A downside: the dimensions of the mattress may be off by up to one inch.

  • Organic center
  • Hypoallergenic
  • Easy to clean 
  • 2 depth sizes 
  • The dimensions are slightly different from standard crib sizes

Delta Children Serta SleepTrue 4†Mini Mattress

10. Best Affordable Mini Crib Mattress: Delta Children Serta SleepTrue 4†Mini Mattress

When you get some of the best qualities of high-end crib mattress brands at an affordable price, you’re bound to be ecstatic. That’s exactly how we were when we found the Serta SleepTrue. 

This mini crib mattress barely costs $65 and is incredibly lightweight (3.9 lbs.), the standard size (38×24 inches), waterproof, easy to clean, and hypoallergenic.

Just like the Delta Children Mini Twinkle Stars, this one too has a core consisting of upcycled plastic bottles. So, you can tick “Organic†off the list of qualities to have in your baby’s mattress too. 

The mattress is dual-sided, so you can flip it to a softer surface when your child grows into a toddler, and it comes with a 10-year warranty. What more could one want, really?  

There’s just one slight issue: the vinyl cover sheet isn’t too cozy. So, you might have to throw on a crib matter topper or flat mini crib sheet to give your child great comfort. 

But all in all, the mattress is certainly great for its price! 

  • Budget-Friendly
  • Organic
  • Dual-Sided
  • 10-Year warranty
  • The vinyl cover sheet is not very comfortable

Final Verdict: The Editor’s Pick

The soundness of a mini crib mattress for you depends upon your decision-making categories. Are you looking for an organic mattress, a thick one, or an affordable one? Will you purchase another mattress down the road, or should you go the flippable way?

While we have given you the best mini crib mattress fit for each category, we did find one that ticked almost all the boxes: the Midnight Slumber Baby Bluebird Mini 5â€. It features impressive stitching and filling. Is stain/odor/water-resistant. Can be flipped and is very durable. It might be a bit expensive, but what’s money when the matter concerns the comfort of our children, really?
