As the saying goes, “You can’t judge a book by its cover,” and the same is true for crib mattresses. Although many crib mattresses look similar on the outside, on the inside they can be made of different types of foam or springs, and may be constructed in different ways.

Find out about the different types of crib mattresses on the market, and what to look for when buying a crib mattress. Then check out our lists of top innerspring crib mattresses and top foam crib mattresses.

To help you find the best crib mattresses, we surveyed more than 6,000 Pampers Parents and asked them to vote on their favorites, and to provide some pros and cons as well so you can make an informed choice.

What to Look for When Buying a Crib Mattress

After finding the right crib for your little one, you’ll be looking for the right mattress.

As many Pampers Parents have noted, it takes a long time to research the best crib mattresses. To help speed the process, we've assembled a list of what to consider when buying a crib mattress:

Quality

When looking for a crib mattress, quality is the number one factor. Cheap mattresses won’t stand the test of time. They’ll usually have thin coverings and edges that can tear or crack from wear.

As mattresses become more expensive, they tend to be thicker and puncture resistant, and have better gauge steel if it’s an innerspring mattress, or denser foam if it’s a foam mattress.

Price

You don’t have to break the bank, but purchasing a high-quality mattress that will serve your baby better in the long run is worth it. The more expensive mattresses tend to be firmer, which is safest for your baby, whereas inexpensive types may be too soft and thin.

Spending somewhere between $90 and $200 will get you a good crib mattress. Five of the mattresses on this list fall in this price range with the Sealy Soybean Foam-Core Toddler and Baby Crib Mattress at around $100 and the Lullaby Earth Healthy Support Crib Mattress at under $200 bookending this price range.

The least expensive standard-size mattress on our list is the Dream On Me Spring Crib and Toddler Bed Mattress which comes in at about $47, and the most expensive mattress on this list is the Naturepedic Classic Organic Crib Mattress which retails around $259.

Safety, Size, and Fit

One very important thing to note: Make sure to buy a crib mattress that’s firmer than you would like, because your baby requires firm support. A firm mattress helps lower the risk of SIDS (Sudden Infant Death Syndrome).

By law, the dimensions of a standard-size crib mattress should measure at least 51 5/8 inches by 27 1/4 inches, and be no more than 6 inches thick. Give or take a little, all the mattresses on this list generally follow these standard dimensions.

The mattress should fit snugly into your baby’s crib so there are no gaps that can trap your baby’s arm or leg. If you can fit more than two fingers between the edge of the mattress and the crib, you should get a larger mattress.

New or Used?

You don’t know what you’re getting when you buy a used crib mattress. It could have mold, bacteria, and stains. When you buy a new mattress, you can feel confident you’re getting one that is sanitary and clean.

After your baby outgrows it, you can use the mattress you buy now for houseguests with a baby or for your next baby. Just make sure to properly clean it once it’s not in use, and store it in a dry location.

The Cover

A crib mattress will have either a fabric or vinyl cover. Fabric is more breathable than vinyl, but some vinyl covers will have ventilation holes.

The benefit of a vinyl cover is that it can resist punctures, tears, leaks, and stains better than a fabric cover.

Look for a mattress with a three-ply cover as this helps the mattress last longer. Among our lists of best crib mattresses, the Dream On Me Spring Crib and Toddler Bed Mattress features a triple-laminated vinyl cover.

Warranty

You can expect a good-quality crib mattress to last as long as you’re going to use it, unless the cover tears. You may not really find much use for a long warranty, and it may not be worth spending extra on an extended warranty.

Still, if warranty is important to you, five mattresses on our lists feature a lifetime warranty. We’ve indicated the warranty period for all the mattresses on our list unless none was provided.

Certification

You’ll notice that many of the mattresses on our list have been certified by various organizations. Two certifications to look out for are Greenguard Gold and CertiPUR-US.

Greenguard Gold certification means that the mattress meets some of the world’s most rigorous standards for low emissions of gasses called volatile organic compounds (VOCs) into the indoor air.

CertiPUR-US is a certification given for any polyurethane foam used in the mattress. Similar to Greenguard Gold, this certification also means the mattress was manufactured to meet low VOC emissions standards, and that the foam meets certain requirements for content, performance, and durability.

But what do these certifications mean for your baby? If the crib mattress you buy has these seals of approval, the mattress was manufactured without harmful chemicals and metals, such as formaldehyde, mercury, or lead, which can affect your baby’s health.

In the product details tables under each product description, we list some of the chemicals that each crib mattress was manufactured without so that you know more about what your little one will (or won't) be sleeping on.

The mattress is shipped rolled up and vacuum sealed, so you’ll want to unroll it and give it 48 hours to expand to its proper size and shape.

Mini/Portable Crib Mattress

If you’re taking road trips together as a family or your baby is spending the night with the grandparents, you might consider buying a portable crib as well as a portable mattress. Here’s the mini/portable crib mattress that Pampers Parents chose as their favorite:

Dream On Me 3 Mini/Portable Crib Mattress

Why pick this one? The Dream On Me portable mattress is designed to fit small-sized portable cribs. It doesn’t fold up, but compact size means it might fit more easily into the trunk of your car.

This crib mattress features a hypoallergenic and anti-bacterial waterproof cover, which inhibits the growth of mold and mildew. It easily wipes clean with warm soapy water.

Highlights: If you have a portable crib, this could be the mattress for you!

Details:

Price*: about $29.99 on Amazon.com

Pampers Parents pros and cons:

  • Pros: It’s very easy to travel with and provides good firmness for your baby.

  • Cons: It’s hard to find sheets for a mattress this small. It could also be a little softer and thicker.

Innerspring vs. Foam Crib Mattresses

There are two main types of mattresses, innerspring and foam. Both do the job, so it’s really up to your personal preference. Find out more about innerspring mattresses just below or jump straight to our section on foam crib mattresses.

Innerspring

With innerspring mattresses, the more layers and the higher the quality of materials, the better. The heavier the innerspring mattress, the likelier it was manufactured with higher-gauge steel springs and better cushioning. The heaviest innerspring mattress on our list at 18 pounds is the Sealy Nature Couture Cotton Bliss 2-Stage Toddler and Baby Crib Mattress.

Another way to check for quality is to look for border rods, which is the piping that goes around the edge of a mattress. This provides firmness, durability, and support so the mattress won’t sag. This is especially important for when your baby stands up in his crib, and walks or bounces on the mattress.

If you’d like a mattress to grow with your baby, you may want to consider buying a convertible mattress. In this style, one side is designed to be firmer, for use when your little one is a baby. Then, the mattress can be flipped to the softer side once your little one reaches the toddler stage. Look for “dual firmness” in the product details table to easily find which mattresses on the list are convertible.

Foam

When it comes to buying a crib mattress, comfort and safety for your baby are most important. We hope this list makes it easier for you to make this important buying decision.

Once you’ve made your choice, you can rest assured that your baby will make good use of his crib mattress! And, with your baby sleeping peacefully, we hope that you will get to enjoy some well-deserved rest, too!

With foam mattresses, denser is better. The denser the mattress, the firmer and safer it is for your baby. The best way to check the density of a foam mattress is to look at how much it weighs. The heavier the mattress, the denser it is. We’ve made it easier for you by listing the weight of each mattress in the product details table.

Look for a foam mattress that is firm and resilient, and heavy for its size. You don’t want the crib mattress to conform to your baby’s body.

When it comes to buying a crib mattress, comfort and safety for your baby are most important. We hope this list makes it easier for you to make this important buying decision.

Once you’ve made your choice, you can rest assured that your baby will make good use of his crib mattress! And, with your baby sleeping peacefully, we hope that you will get to enjoy some well-deserved rest, too!
