Moonlight Slumber Little Dreamer Crib Mattress

The Little Dreamer mattress excels in most tests. However, in a hand-me-down crib with looser springs, we noticed a lot of sinking and sagging. Read More

Cons

  • Sags quite a bit in certain cribs

Lullaby Earth Breeze Breathable 2-Stage Crib Mattress

The Earth Breeze mattress might sound like an easy choice, but the infant side's so firm that you may end up costing yourself a lot of lost sleep. Read More

Pros

  • Removable cover
  • Waterproof surface

Cons

  • The infant side is probably too firm

Finding the best crib mattress for your baby is perhaps one of the most important decisions a new parent makes. A too-soft mattress poses a safety hazard for newborns, while an extra firm mattress can make it difficult to get the baby to sleep at all (and a sleep-deprived parent is a considerable hazard in and of itself).

As a mother of three, I know how tough this decision can be. You want the safest surface for your baby, you want your baby to sleep comfortably, and you want to have a few bucks left in the bank for diapers after you’ve purchased the mattress.

We tested seven of the best-selling and highest-rated crib mattresses on the market for four main criteria: firmness, ease of cleaning, odor, and special features. It’s not easy to meet all of these needs with one model, but we found a happy medium with the Colgate Eco Classica III Dual-Firmness crib mattress (available at Amazon).

Here are the best crib mattresses ranked, in order:

  1. Colgate Eco Classica III
  2. Delta Children Twinkle Stars
  3. Naturepedic Ultra Breathable 2-Stage Organic
  4. Moonlight Slumber Little Dreamer
  5. Lullaby Earth Breeze
  6. Sealy Soybean Foam Core
  7. Safety 1st Sweet Dreams

Colgate Eco Classica III

Material: Cotton cover and eco-foam
Dual sided: Yes
Warranty: Limited lifetime

Even before testing, we were immediately drawn to the Colgate Eco Classica III. As a top seller on Amazon, we had high expectations for this mattress which were (mostly) met.

The Colgate Eco Classica III is both CertiPUR-US and Greenguard Gold certified, which means it comes out of the package with very little smell, and the smell it does have is somewhat earthy and not unpleasant. These certifications also mean, of course, that the mattress is considered to emit very low levels (if any) of harmful chemicals, AKA volatile organic compounds (VOCs). That’s a plus because nobody wants their baby breathing in that business all night.

The Eco Classica III is a dual-sided foam crib and toddler mattress, so it's a good combination of safety and comfort from birth through toddlerhood. The infant side is firm without feeling too hard for comfort, while the toddler side has just enough give without being too soft—making it ideal for a toddler bed. The edges are squared instead of rounded, which makes for a secure mattress fit inside the crib.

It’s covered in an organic cotton cover that provides breathability while protecting the mattress itself from liquids. The cover is wonderfully soft, but it was also the source of our one major gripe with this mattress: the cover isn’t removable for washing. While it may protect the mattress itself from liquids, the cover soaked them up and stained terribly in our tests. The fact that you can’t remove and wash the cover feels like a glaring design flaw, but if you’re willing to top it with a separate mattress pad, it’s a great mattress.

Pros

  • Free of harmful chemicals

  • Has both an infant side and a toddler side

Cons

  • Prone to stains

Delta Children Twinkle Stars

Material: Vinyl cover, recycled plastic fiber core
Dual sided: Yes
Warranty: 7 years

We tested three mattresses : the Safety 1st Sweet Dreams, the Sealy Soybean Foam-Core, and the Delta Children Twinkle Stars. Of the three, we liked the Delta Children Twinkle Stars best.

While overall none of these three are super firm like the higher-end mattresses we tested, the Delta Children Twinkle Stars is not as squishy at the edges as the Safety 1st or the Sealy. We felt more confident that we’d have fewer issues with trapped fingers between the mattress and the crib sides with the Delta Children Twinkle Stars than the other two.

Unfortunately, the coffee we poured onto the baby mattress surface soaked into the stitching on the side, but we felt the safety aspect was more important.

Aside from the edges, the three mattresses performed very similarly in our testing. The Sealy came out of its package with less of a chemical smell than the Delta, but we didn’t feel the difference was enough to justify spending twice as much.

We found that, when it comes to crib mattresses, the old adage “you get what you pay for” rings true. We’d recommend you step up to the Colgate Eco Classica if possible, as there’s a considerable difference in the quality and feel of these two mattresses, but if your budget is tight, the Delta Children Twinkle Stars is a safe bet.

Pros

  • Firm edges

Cons

  • Easy to stain

Other Crib Mattresses We Tested

Product image of Naturepedic Ultra Breathable 2-Stage Organic Crib Mattress
Naturepedic Ultra Breathable 2-Stage Organic

Material: Organic cotton
Dual sided: Yes
Warranty: Limited lifetime

The Naturepedic Ultra Breathable 2-Stage Organic crib mattress was hands-down our favorite of those we tested. It smells pleasant, it performed well in our stain resistance tests, it’s dual-sided, and it has a breathable organic cover that (unlike the Colgate) can be removed and washed. The cover is beautifully quilted and the mattress itself is solid yet light enough for easy sheet changes. It just looks and feels like quality.

A number of Reviewed staffers have kids who’ve used the Naturepedic and it garners rave reviews from every single one. It’s firm and supportive, the mattress fit well in a variety of crib brands, and every parent appreciated the removable washable cover.

So if it was our favorite, why doesn't it top the list? Because that quality comes at a price: in this case $399. We felt that was just too much for many families. However, if your crib mattress budget allows it, we’re confident you’ll be very pleased with the Naturepedic.

Pros

  • Smells pleasant

  • Stain-resistant surface

Cons

  • Overpriced

Product image of Moonlight Slumber Little Dreamer Crib Mattress
Moonlight Slumber Little Dreamer

Material: Performance fabric cover, foam interior
Dual sided: Yes
Warranty: Lifetime warranty

The Moonlight Slumber Little Dreamer was one of only two mattresses that we tested that refused to stain, no matter what we threw at (or on) it. Spaghetti sauce and coffee both wiped away without a trace, making it a truly waterproof crib mattress.

This mattress also boasts the squared edges we liked so much on the Eco Classica III, and when we tested firmness with the mattress on the floor, it seemed solid while staying comfortable on both the infant and the toddler side. However, once we put the mattress in our crib, we felt it sagged too much. Granted, our crib has survived through two rowdy toddlers and the springs are probably not as stiff as they originally were, but many babies sleep in hand-me-down cribs, so we thought this was worth noting. On a solid surface, we loved the Moonlight Slumber Little Dreamer. On a surface with some give, it just sunk in more than we were comfortable with.

Pros

  • Near impossible to stain

  • Solid and comfortable

Cons

  • Sags quite a bit in certain cribs

Product image of Lullaby Earth Breeze Breathable 2-Stage Crib Mattress
Lullaby Earth Breeze

Material: Cotton cover, food-grade polymer interior
Dual sided: Yes
Warranty: Limited lifetime

The Lullaby Earth Breeze boasts many of the features we also loved about the Naturepedic Ultra Breathable 2-Stage Organic mattress. It has a removable, breathable cover as well as dual firmness and a waterproof cover.

It is the only mattress that didn’t let off any kind of smell when we unpackaged it, and despite the similarities, the Lullaby Earth Breeze is considerably less expensive than the Naturepedic.

What we didn’t love was that the infant side of the mattress is firm to the point of being hard. It was firmer than all the others we tested by quite a lot. Maybe it’s extra safe, but the sleep a parent could lose trying to get their infant to sleep on such a hard surface is also a hazard worth considering.

Pros

  • Removable cover

  • Waterproof surface

Cons

  • The infant side is probably too firm

Product image of Sealy Soybean Foam-Core Crib Mattress
Sealy Soybean Foam Core

Material: Soybean foam
Dual sided: No
Warranty: Lifetime

While we were happy with the overall firmness of the Sealy Soybean Foam Core crib mattress, the edges sank under very little pressure, even in comparison to the more-affordable Safety 1st Sweet Dreams and Delta Children Twinkle Stars crib mattresses.

While we liked the more eco-friendly soybean foam mattress interior and the fact that it has both the CertiPUR-US and Greenguard Gold certifications, we didn’t like that this is not a dual sided mattress. Plus, the top layer of this mattress also made a lot of crinkling noise when our toddler tester moved around on it, which we were worried could disturb precious slumber.

Pros

  • Good overall firmness

Cons

  • Unsupportive at the edges

  • Noisy

Product image of Safety 1st Sweet Dreams Crib and Toddler Mattress
Safety 1st Sweet Dreams

Material: Vinyl cover, polyester filling
Dual sided: No
Warranty: 24 months

The Safety 1st Sweet Dreams crib mattress was the most affordable of those we tested, but }other than its low price we weren’t impressed.

Out of the package, it had a definite chemical smell, and the sleep surface was very crinkly. It deterred stains well, but the surface doesn’t feel especially durable. We wouldn’t expect it to last through multiple children without some tearing and cracking, but at this price point, you could just buy a new one for each child.

Pros

  • Stain-resistant surface

Cons

  • Unpleasant chemical smell

  • Doesn't feel durable

How We Test Crib Mattresses

We used coffee and marinara sauce to test spills and stains on all the mattresses. Raised edges are essential to trapping spilled liquids (left), but boy those stains can be tough to scrub out (right)!

We tested each crib mattress on four main criteria: firmness, how easy they were to clean, odor, and special features.

To test firmness, we had a 35-pound toddler sit in the middle of each mattress and noted how much the surface indented under her weight. If the mattress had both infant and toddler sides, we tested the firmer (infant) side.

We tested each mattress for stain resistance by dumping a half cup of chunky marinara sauce as well as a quarter cup of coffee onto the surface. We immediately wiped the mattresses off and noted how easy they were to clean and whether a stain remained after scrubbing with dish soap.

To test odor, we lined all the mattresses up immediately after unpacking and compared the amount and kind of smells they put off. None were overpowering, though the smells ranged from chemical to earthy.

Finally, for special features, we rated the crib mattresses on whether or not they had a firm side (for infants), and a softer side for toddlers.

What You Should Know About Buying a Crib Mattress

There are volumes upon volumes you can read about healthy baby sleep, and helpful resources like the American Academy of Pediatrics about where to put the crib and how to reduce the risk of Sudden Infant Death Syndrome, but here are some things to think about when selecting a crib mattress:

What material is the mattress made of?

You want the safest sleep environment possible for your baby, so choosing a crib mattress that doesn’t contain a lot of chemicals is important. That being said, you also don’t want the mattress material to be noisy, as a crinkly mattress doesn’t exactly promote peaceful slumber. Try to find a mattress that’s non-toxic, but also has a soft exterior (and that’s hopefully waterproof).

Is the mattress dual-sided?

Infants need a firm mattress in order to promote safe sleep, but once your child is a toddler they may prefer a softer surface for their slumber. A dual-sided crib mattress—clearly labeled with “infant side” and “toddler side”—is a good investment if you plan to use it past your child’s first year.

What’s the crib mattress’ warranty?

Baby gear gets hard use, and crib mattresses are no exception. Selecting a mattress with a lifetime warranty ensures that you’ll be able to get a replacement if it doesn’t hold up to average wear and tear.

How waterproof is the mattress?

Real talk: there’s a lot of pee during the baby and toddler years, so having a waterproof mattress is a non-negotiable. If the mattress claims to be waterproof but doesn’t actually deliver, you could end up with a baby sleeping in a puddle of urine—and be out the cost of a ruined crib mattress.

What size is a crib mattress?

By Federal law, crib mattresses have a minimum size of 27 1/4" x 51 5/8” with a thickness not exceeding 6 inches. Also, cribs themselves have a mandated interior size of 28” x 52 3/8”. But because there's an allowable tolerance for cribs (i.e. it can be a little smaller or larger than the target size), the mattress may have some wiggle room in the crib. Or worse, it may be too big. So hang onto that receipt.

A mini crib mattress is smaller

Don’t purchase a standard size crib mattress and expect it to fit in a mini crib; you’ll need a smaller mini crib mattress—generally measuring 24 by 38 inches—designed just for these more compact models. A number of the brands we tested offer mini crib-sized versions of their popular mattresses.

Never buy a used crib mattress

While it can be tempting to accept every hand-me-down offered, when it comes to crib mattresses, it’s best to politely decline. Older mattresses may not have been subject to the same safety regulations as modern mattresses. Mold and bacteria can also grow on old mattresses, depending on cleanliness and how they were stored.

Crib mattresses are required to be fire-resistant

There are both Federal and State flammability standards that mattresses are required to pass before they can be sold. But the chemical and material composition of the mattress may vary widely from brand to brand. The presence or absence of certain flame retardants (beyond those banned by law) is a hotly debated topic in some circles. In rare instances there have been safety recalls. We'll be keeping an eye on mattresses we recommend in this roundup if there is ever news.

How “organic” is it?

Everybody wants the best for their baby, and buying organic is frequently a must-have for parents. Unfortunately, there are no legal standards for the terms "organic" or "natural" when it comes to crib mattresses. It may refer to some of the material, like cotton or wool, but not other components.

If this is your make-or-break criteria, read the brands' websites carefully. Many of our recommendations here, like Naturepedic, take the topic very seriously and write about it at length on their site. CertiPUR-US and Greenguard Gold certifications might also be useful to know about, but understand that each is designed to test only specific attributes.
