Two of the most important items parents buy for a new baby are a crib and mattress. The problem? There are thousands of cribs, and mattresses, to choose from.

Feeling overwhelmed? Don’t worry, we did, too.

In this article, we’ll examine some of the most popular crib and toddler mattresses. We’ll also discuss the most important points parents need to know before purchasing a mattress for their baby.

The Emily Crib Mattress is a heavy-duty organic innerspring mattress with a supportive edge, 150 coils, and a gauge of 13.5. Its wool cover is naturally resistant to dust mites, mildew, and mold, and wool’s natural resistance to fire allows the mattress to pass flammability tests without using chemicals. For insulation, the Emily mattress features heavyweight organic cotton batting.

This mattress is certified by GOTS (the Global Organic Textile Standard), as well as by GREENGUARD. As would be expected from an organic mattress, it does not contain any lead or polyurethane foams.

The pros: The Emily Crib Mattress is a firm mattress that’s naturally flame-resistant, and uses organic materials. It also meets the global standards for organic textiles.

The cons: This mattress isn’t cheap, and it’s not completely waterproof. However, both of the mattress’ sides provide equal firmness, allowing parents to alternate sides when necessary.

Want a closer look at the technical details of each mattress?

What else do you need to know?

Foam vs. innerspring

Crib mattresses come in two types: foam mattresses, and innerspring mattresses.

One point to keep in mind is that innerspring mattresses are less likely than foam mattresses to retain indentations, but are more likely to provide a fun (but dangerous) jumping ground for active babies and toddlers.

Both innerspring and foam mattresses may (or may not) have an easy-to-clean vinyl cover.

Here’s what you need to know about teach type:

Foam mattresses

Foam mattresses are lightweight, and vary in both thickness and density. Look for a mattress between 3 and six inches thick. Be sure that the mattress is dense enough that you can’t squeeze it, and that pushing it down is difficult. The denser the mattress, the firmer it will be (and the longer it’ll last).

Most foam mattresses are made from polyurethane, and foam mattresses tend to weigh between 5-13 lbs.

Innerspring mattresses

Possibly because of their similarity to adult mattresses, innerspring mattresses are more popular than foam mattresses in the US. These mattresses contain spring coils, providing firmness for several years.

If you choose an innerspring mattress, be sure there is enough insulation on both the top, sides, and corner to protect your baby from the springs. The best insulation contains fiber-wrap or coir-fiber, topped with either foam or cotton.

Innerspring mattresses are usually heavier than foam mattresses, with weights ranging between 15-30 lbs. However, they are also more durable and less likely to contain chemicals.Buying an innerspring mattress doesn’t guarantee firmness, though, so be sure to test the mattress before buying.

Never buy an innerspring mattress without border rods, also called edge support. These rods encircle the mattress’ upper and lower perimeters, ensuring the mattress won’t sag when pressure is placed on its edge.

When buying an innerspring mattress, check both the gauge and coil numbers. Gauge numbers range from 19 to 12.5, with the lower numbers being thicker steel. Coil numbers go in the opposite direction: the less coils, the softer the mattress will be. Look for at least moderately thick steel, with at least 150 coils.

Waterproof and water-resistant mattresses

Vinyl-coated mattresses are usually waterproof and easy to wipe clean. Mattresses covered with cotton, however, may be marketed as “water-resistant” – but may not actually be waterproof.

Though a water-resistant mattress will absorb much of a spill or leak, it will still require cleaning after large spills or leaks. If you do choose a cotton-covered mattress, be sure it (or its cover) can be washed in your washing machine.

If your mattress is not waterproof, it may be worth buying a mattress pad, either with or without a waterproof backing.

Mattress size

Crib mattresses need to fit snugly into the crib, without leaving any empty space. The reason? An ill-fitting crib mattress can cause strangulation or suffocation at worst, and trapped limbs at best.

Crib mattresses should be between 4 and 6 inches in depth, between 27.625″ and 28.625″ in width, and between 51.75″ and 53″ in length.

To test whether a mattress fits properly into your crib, try to insert two fingers into the space between the mattress and the railings or side of the crib. If you can do it, the mattress is too small and you need a different one.

Keep in mind that if you are using a mini-crib or pack ‘n play you will need a smaller size mattress. Even smaller size mattresses are needed for bassinets, and no mattress is needed for a moses basket or co-sleeper.

Firmness and breathability

Crib mattresses need to be firm, and should not sink when weight is placed on them. To test a mattress’ firmness, press down hard with your hand. If you see an indentation, it’s not firm enough. If it pops back up, you’re good to go. Also, hold the mattress between your hands and squeeze. If the mattress retains the shape of your hand, don’t buy it.

Remember, you don’t want a mattress that feels good to you. A mattress that feels good to an adult is almost certainly a mattress which is too soft for a baby. Choose one that’s firm – you can always add a soft mattress pad when your baby hits one year.

Also check that foam mattresses are at least somewhat breathable so they don’t overheat. Innerspring mattresses, like adult mattresses, should have a proper vent in the side (or some other solution) to allow air flow.


Cheaper mattresses may have thin coverings which will tear or dry out over the years. Higher quality mattresses will have thicker coverings, either made of thicker vinyl or of good quality cotton. And higher quality innerspring mattresses will have better gauge steel , as well as better insulation and edge support.

It’s important to note that a higher price tag does not necessarily correlate with a higher quality product. Also, when it comes to crib mattresses, look for a warranty of one year – and no more. A good quality crib mattress should last as long as you need it, and the only reason to replace it would be a tear in the cover, or a lack of firmness.

Double-sided mattresses

Some crib mattresses have a soft side for toddlers and a firm side for babies. These mattresses can be used either in a crib (most cribs are intended for children up to three years of age) or in a toddler bed (up to age five or six).

It’s important to note that crib mattresses can be used for toddler beds as well, provided your toddler bed has the same dimensions as the crib. The “toddler side” of a two-stage mattress is simply softer and more comfortable than the “crib side.”

However, if your ideal mattress does not offer a toddler option, don’t worry. While a toddler side is a nice addition, it’s not absolutely necessary. If you’d like to make your toddler’s bed more comfortable, simply add a blanket, mattress pad, or mattress topper to his crib mattress.

NOTE: Always use the firm side of a two-stage mattress for babies under 1 year (12 months) of age.

Organic crib mattresses

Most non-organic crib mattresses are covered with vinyl, and contain various chemicals. While these chemicals aren’t dangerous, many parents prefer to avoid them if possible.

If you do choose an organic mattress, make sure it is actually made from natural materials and carries the label CertiPUR-US, or GOTS:Not every mattress which claims to be organic is made of all-natural materials. Since there’s no standard for organic crib mattresses, manufacturers can write whatever they want, and it’s up to the consumer to be aware.

Also be sure that it your chosen mattress is waterproof, or at least water-resistant. Babies will spit up, pee, and poop, on their mattresses, and you need to make sure the mattress remains hygienic until your baby no longer needs it.

Another thing to keep in mind is that many non-organic mattresses are fire-retardant, and all mattresses need to meet flammability standards. If a completely organic mattress is important to you, be sure to choose an organic mattress covered in naturally fire-retardant material, such as wool.

Should you buy a used crib mattress?

No. While you can reuse your first baby’s crib mattress for your second baby, don’t buy a used crib mattress from someone else. Studies show that babies sleeping on a crib mattress used in another home are more likely to die from SIDS.

While it’s not clear why this is so, we do know that smoking is a major cause of SIDS, and that cigarette smoke can be absorbed into fabric and furniture (this is called third-hand smoke).

It’s not clear, but it could well be that a crib mattress from someone else’s home was exposed to chemicals from cigarettes,which could influence your child. This, by the way, seems to be much more plausible an explanation than blaming the chemicals in a mattress’ vinyl cover.

Another issue with used mattresses is that they’re often no longer as firm as they should be, or have tears, mold, or other problems. It’s best to avoid the risk entirely and buy a new mattress for your child’s crib. (You can, however, buy a used crib, as long as it meets current safety standards).

How should you store your crib mattress?

If you bought a crib mattress for your first baby, you’ll probably want to save it for your second to use as well.

Place your crib mattress in an appropriately-sized plastic bag (avoid bags which are too big), and store it in a cool, dry, place. If possible, choose a bag that’s not opaque, since light inhibits the growth of both mold and bacteria.

Proper care and storage will ensure your child’s crib mattress remains usable even after he outgrows it.

The bottom line?

Babies sleep over twelve hours each day, so it’s important to make sure their beds are as safe as possible. Both cribs and mattresses play an important role in keeping babies safe, and knowing what to look for is the key to providing a safe sleep environment for your child.

While there’s certainly a crib mattress for everyone, deciding which mattress to buy can be a daunting task.

Here’s a tip: Before you go mattress-hunting, make a list of what’s important to you.

Do you need a double-digit price tag? Are organic baby products built into your soul? Are you okay with a mattress that’s equally firm on both sides, or do you need a mattress that has a soft side and a firm side?

The answers to these questions and others will guide you to the right mattress, and help you decide which criteria to compromise on, and which are non-negotiable.

Make your list, then reread this article and choose the mattress that best suits your needs.
