Factors to Consider Before Buying a Crib Mattress

Use a waterproof cover

Your crib mattress cover should be waterproof to resist any accidents or spills that are common with babies. If the mattress or mattress cover is not waterproof, there’s an increased likelihood of mold or mildew building over time from the retained moisture. Mold can lead to health issues especially if your baby has asthma or allergies. Even if your mattress is designed to resist moisture, regularly inspect the crib mattress appearance and smell.

10 Crib Mattresses to Help Your Baby Sleep Safe and Soundly

Here’s hopingeveryonewill snooze through the night.

Newborns spend most of their time sleeping, so the crib mattress is one of the most important purchases you’ll make as a new mom or dad (no pressure, right?). First and foremost, it needs to be supportive and made with safe materials. On top of that, it should be easy to clean for inevitable accidents and have dual firmness if you want to continue using it when your baby becomes a toddler.

The Good Housekeeping Institute scientists, engineers, and parenting experts review baby gear of all kinds, with a big emphasis on sleep-related products like cribs, swaddle blankets, sleep sacks and more. We’ve picked the top crib mattresses ahead that offer something for everyone, no matter what your preferences are for your baby’s crib. But first, here’s what to consider as you shop for a crib mattress:

What is the best type of mattress for a baby?

The best mattress for a newborn is one that’s extra firm; in fact, it should be so hard that as an adult, you can’t imagine it possibly being comfortable to sleep on. When the baby is about a year old, they can have a slightly softer (yet still firm) surface to sleep on. Many crib mattresses are reversible with infant and toddler sides so you can use them same one for several years.

Just like the inner materials in an adult mattress, for crib mattresses, you’ll commonly choose between an innerspring or foam.Innerspring mattresseshave steel coils to make it sturdy (the more coils, the more supportive it’ll be), whilefoam mattressesare usually made of dense yet lightweight polyurethane foam. Foam mattresses safe for your child to sleep on as long as they’re firm enough. Lastly, to make certain that you’re not exposing baby to harmful levels of off-gassing VOCs, check that the mattress is GreenGuard gold certified, which means the product has been reviewed to ensure low emissions.

How tight should a crib mattress fit?

There should be no gaps between the mattress and the crib sides. If you can fit more than two fingers between the sides of the crib and the mattress, it’s too small and therefore poses a risk to your child. The crib sheets also need to fit securely enough that your baby can’t pull the edges up. An infant’s crib should have nothing else in it: no pillows, blankets, stuffed animals, or other toys. There also shouldn’t be anything hanging over the crib that baby can pull down.

One more safety tip to keep in mind: when it comes to crib mattresses, it’s best to buy new instead of used. A used one may not be as firm, can have mildew or bacteria growth, and may not be up-to-date with the latest safety regulations.

Here are the best crib mattresses you can buy for your baby:

How firm mattress for baby

Getting Started
Choosing a crib mattress might seem like a boring task but it’s one that warrants careful consideration. The mattress is as important as the crib, and we recommend buying the best one you can.

Why does it matter? For one thing, your baby will spend a lot of time in his crib. It might seem hard to believe, especially when you’re getting up to feed a fussy baby in the middle of the night, but infants sleep up to 18 hours a day.

You’ll want to make sure the mattress fits properly in the crib you’ve selected without gaps that could pose a danger to your baby. And the mattress should be firm. A soft one can conform to the shape of your baby’s head or face, increasing the risk of suffocation or even sudden infant death syndrome (SIDS).
There are two general types of crib mattresses: foam and innerspring. Both types—if they’re good quality—will keep their shape well and provide excellent support for infants and toddlers. There are differences, though. Foam—usually made from polyurethane—tends to be lighter (about 5 to 13 pounds) compared with an innerspring mattress (about 15 to 30 pounds). So although you’ll probably be lifting just a corner at a time when changing your baby’s sheets, it might be a bit easier with a foam mattress. Foam is also less springy and therefore less likely to be used as a trampoline when your child is older. Still, innerspring crib mattresses are more popular in the U.S., possibly because most adults sleep on innersprings, too.

Look for Quality
Whichever type of mattress you chose, look for quality. The cheapest foam and innerspring mattresses have thin vinyl coverings and edgings that can tear, crack, and dry out over time. As prices increase, coverings tend to be thicker, puncture-resistant, reinforced double or triple laminates, or very fine organic cotton. An innerspring mattress that has more or better-gauge steel and better-quality cushioning will weigh more. The same goes for a foam mattress that’s made of denser, better-quality foam.

Still, you don’t have to spend a fortune or try as many mattresses as the Princess and the Pea to get a good-quality one. A mattress that costs between $90 and $200 will generally serve your baby well. Prices for foam and innerspring mattresses are comparable, ranging from $50 to $400 and up. (The more expensive ones are made with organic cotton or natural latex.) Low-priced models (less than $90) might be too soft and flimsy. Higher-priced models tend to be firmer and therefore safer.

You Can’t Tell a Mattress by Its Cover
With a mattress, almost everything that matters is on the inside. Some crib mattresses feel great in the store but begin to falter once your baby starts to use it. We’ve learned that you can’t depend on sales staff, even at reputable retail outlets, to give you accurate information. One told us, quite convincingly, that innerspring mattresses were better than foam because foam tends to "break down" after 18 months. Twenty-five years ago that may have been true, but not anymore. "A top-quality foam crib mattress will hold up just as long as an innerspring crib mattress with normal use," says Dennis Schuetz, director of marketing for the Colgate Juvenile Products Company, a manufacturer in Atlanta. That’s because foam crib mattresses have become much more durable.

Hit the Stores
Once you get a sense of options in different price ranges, you should go to a store to see what a quality crib mattress looks and feels like. One place to start? The label. Manufacturers are required by law to reveal what a mattress is made of. Don’t buy one from a manufacturer or retailer that doesn’t tell you this with in-store information, displays, or online specifications. In fact, you should be able to find out the components of each layer. And when you push down on a mattress, your hand should spring right up. Schuetz says the biggest mistake parents make is picking a mattress that’s comfortable for them. It’s better to pick a crib mattress that’s harder than you would like it to be. "If it feels good to you, it’s too soft for your baby," he says, adding that babies need more support than adults.

Buy New
Buy a new crib mattress, if possible. For one thing, it ensures that the mattress is sanitary. If you buy a used mattress or accept a hand-me-down, you won’t know for sure how it was cared for or stored. Mold can grow in improperly stored crib mattresses, and bacteria can fester on the surface from liquids (diaper leakage, spit-up) that weren’t properly cleaned up. If you buy a new one for your first child and keep it clean, you can use it for your next child if you store it in a dry environment and it stays firm.

Use a Cover
Use a tightly fitting, washable waterproof mattress cover to protect the mattress and keep the baby’s sleeping environment as clean and sanitary as possible.

Test the Fit
By law, all full-sized crib mattresses must be at least 27 1/4 inches by 51 5/8 inches, and no more than 6 inches thick. If you can, shop in a store that displays crib mattresses on the selling floor, and check the fit by putting it inside a sample crib before you buy it. If you can squeeze more than two fingers between the mattress and the crib, the mattress is too small.

Don’t Worry About Warranties
Some mattresses offer warranties for one year, seven years, or even a lifetime. Don’t be swayed by a long warranty, and don’t pay extra for a mattress with a warranty. "Warranties are mostly a marketing tool to entice the consumer to spend more," Schuetz says. In general, you can expect a quality crib mattress to last as long as you’re going to use it as long as the cover doesn’t rip or tear.

We have not tested any of these crib mattresses.

The Best Crib Mattresses for Baby

Ever pressed down on a crib mattress to test out the comfort factor? If so, your first thought might have been,It’s so hard — is my baby actually going to be able to sleep on this?

Yes, she will. More than that, though, it’s essential that your baby’s crib mattress be anything but plush. Although the following statistic can be tough to think about, approximately 3,600 babies die suddenly and unexpectedly every year in the U.S. from Sudden Infant Death Syndrome (SIDS). "Safe sleep practices are the best way to reduce the risk of this happening,” says Rachel Y. Moon, M.D., an investigator with the Child Health Research Center at the University of Virginia School of Medicine.

In addition to following safe sleep practices such as "back to sleep" and keeping soft bedding like blankets, pillows and crib bumpers out of the crib, having a well-designed and firm crib mattress is important to prevent SIDS.

What to look for in a crib mattress

“Crib mattresses should be firm, which means hard,” says Dr. Moon. “A hard mattress will not mold to the shape of the baby. Just becauseyouwould prefer a softer mattress does not mean that your baby would."

You’ll also want to make sure that the mattress fits snugly into the crib frame, adds Dr. Moon, as gaps between the rails and mattress can also pose a safety hazard.

Types of crib mattresses

In addition to essential safety features, there are a few other details you might consider when shopping for a crib mattress.

Dual-sided:Some crib mattresses are dual-sided, meaning they are designed to be firm on one side for infant sleeping and then can be turned over for a slightly softer sleep surface once your little one is a toddler. This certainly gives you more mileage from the mattress, but note that many toddlers remain content sleeping on firm mattresses for years.

Breatheable materials:You may find that some crib mattress brands advertise their “breathable” materials (like mesh), which can mean they don’t trap as much heat, lessening the risk of major baby sweat. Remember, though, that even with a “breathable” mattress, baby still needs to be put down on her back to go to sleep.

Green Guard certification:For some parents, it’s important that their baby’s crib mattress has Green Guard certification, which is used to identify products made from materials that give off low or no emissions of potentially harmful chemicals called VOCs.

Mess-proofing:Mattresses are usually made with a few different layers, including a core (often foam) topped with a barrier layer (to prevent liquids from seeping in) and a top cover (e.g. cotton, polyester or a blend) that may be water- or allergy-proof for added peace of mind (and cleanliness). What you choose depends on your baby’s needs and what qualities you deem most important.

This can seem like a lot to think about, but don’t worry: you can — and will — find the right crib mattress for baby.
