4 Best Crib Mattresses, Tested by Families

In a nutshell

Based on hands-on product testing and expert input, we found the Newton Original Crib Mattress to be the overall best crib mattress. It features high-quality materials that support both safety and comfort from infancy through toddlerhood, but our tester was especially impressed by its washable cover and core, as well as its overall comfort.

In haze of those early newborn days––and every sleep regression thereafter––sleep deprivation may have you googling unhinged questions like, “What’s the exact hour and minute I should start my baby’s bedtime routine so they sleep through the night?” (Guilty, at 3 a.m. with both of my babies). And while there’s no magic bedtime formula, one of the best ways to set your baby up for better sleep is by starting with a safe, supportive crib mattress.

“A lot of people don’t realize how much of an impact the structure and quality of their mattress has on their sleep,” says Rachel Mitchell, CEO & Certified Sleep Specialist for My Sweet Sleeper. “When choosing a mattress, there are a lot of options so it is a good idea to do some research and test out mattresses that fit your sleeping style.”

When it comes to a great crib mattress, there’s more than meets the eye––and putting in the extra effort to find one is worth every extra minute of glorious shut-eye. We’ve done the legwork for you, breaking down what to look for and rounding up the best crib mattresses to help you find the perfect fit.

How We Tested and Chose the Best Crib Mattresses

To help you find the best crib mattress for your baby, we researched dozens of options and then put the top choices to the test. Here are the steps we took to get to our recommendations:

• We tested 9 crib mattresses with 9 different families, with babies and toddlers from 18 weeks to nearly 5 years old. Each mattress was used over multiple nights of sleep and evaluated based on ease of setup, size and weight, firmness for both infants and toddlers, comfort and effectiveness for both baby and toddler, materials and quality, ease of cleaning and value for money.
• Our hands-on product testers rated the mattresses on a scale of 1-10 across every category. The ratings helped us create a shortlist of 4 standout crib mattresses recommendations.
• We also interviewed a certified sleep specialist to provide expert insight on safety, materials and best sleep practices.

Types of Crib Mattresses

There are several types of crib mattresses available, each with different features and benefits. Here are the main types to consider:

• Innerspring crib mattress. Similar to a traditional adult mattress, innerspring crib mattresses feature sturdy metal coils surrounded by layers of soft padding. They’re known for being durable and holding their shape well. Mitchell notes that these types of mattresses, “generally have a lot of overall support.” The trade-off is that they tend to be heavier. If you opt for an innerspring mattress, pay attention to coil count—the number of springs inside the mattress. Higher coil counts typically mean a firmer, more supportive surface (ideal for infants), but they can also come with a higher price tag.
• Foam crib mattress. Made from high-density polyurethane foam, these mattresses are lightweight and easy to maneuver––especially during middle-of-the-night sheet changes. They’re often more affordable and easy to clean. Look for high-density foam, which provides the firm support babies need. Just be aware that foam mattresses may soften over time with extended use.
• Hybrid/double-sided crib mattress. A hybrid or double-sided mattress offers the best of both worlds––typically made from foam or a hybrid of innerspring and foam, this type features a high-density, firm side for infants and a softer side for toddlers. While they tend to be more expensive upfront, their dual-sided design can extend their lifespan. Just be sure to keep track of which side is facing up when changing sheets.
• Air-Core/breathable crib mattress. A newer option on the market, breathable crib mattresses are designed to promote airflow through the sleep surface. They typically feature a ventilated cover and a core made from food-grade polymer, which allows air to circulate freely. Mitchell says this is a great option for those who run hot during sleep. Some parents also find these mattresses reassuring once their little ones start rolling and prefer sleeping on their tummies.
• Natural fiber crib mattress. Crib mattresses made from natural fibers—like organic cotton, coconut coir, sugarcane and wool—are good choices for families looking to prioritize natural, more sustainable materials. While often more expensive and limited in options, they can be appealing to those wanting to reduce exposure to certain chemicals. Note that “natural” refers to the materials used––not a specific mattress type–– so you’ll find these features across a range of mattress styles

What to Look For in a Crib Mattress, and How To Keep Them Safe

Safety is key when choosing any baby product––especially a crib mattress. The right sleep setup not only leads to better quality rest, but also reduces the risk of Sudden Infant Death Syndrome (SIDS). Some features––like waterproofing or cooling––come down to personal preference, but safety should be the top priority. According to the American Academy of Pediatrics (AAP), a crib mattress should provide a firm, flat surface that doesn’t indent when baby lies on it. The sleep space should be free from loose bedding and only contain the mattress with a tight, fitted sheet designed specifically for that model. Following these guidelines can help reduce the risk of Sudden Infant Death Syndrome (SIDS).

As you compare crib mattresses, keep these factors in mind:

• Firmness. It may not seem comfortable to you, but baby mattresses need to be firm. “Using a firmer mattress with infants is important because it decreases the risk of suffocation and helps support the proper sleeping position,” says Mitchell. “When mattresses are too soft infants can sink into the mattress, and this increases the risk of suffocation, especially in the first few months of life.” For safe sleep, infants should always be placed on a surface that doesn’t indent or contour to the shape of their head. A simple way to test the firmness of a mattress––it should immediately spring back into its original shape. If you can still see an indentation, it’s not firm enough for baby. As your child transitions into toddlerhood and can manage turning over on their own, you can switch to a slightly softer mattress, but it should remain firm and supportive. Dual-sided mattresses provide a firmer infant side and a softer toddler side, often with instructions on when to flip it.
• Density. If you’re considering a foam mattress, density is another factor to consider. Density refers to how much material is packed into the foam, affecting both durability and support. Higher-density foam mattresses tend to be more supportive and long-lasting. Softer, low-density foam may allow a baby to sink too deeply into the mattress, which can pose a safety risk. To get a sense of density, try pressing on the sides of the mattress to see how pliable it is––denser foam will feel more resistant to squeezing. High-density foam is different from memory foam, which is not recommended for infant sleep surfaces.
• Size and fit. Your crib mattress should fit snugly inside the crib frame. According to AAP’s sleep safety guidelines, there should be no more than about two fingers’ width of space between the mattress and the crib sides. “Gaps increase the risk of suffocation and your baby getting stuck, which is definitely unsafe.” says Mitchell. The mattress should also lie flat within the crib frame without any tilting or angling.
• High-quality materials. Crib mattresses are strictly regulated, however it’s still worth paying attention to the materials used. Our advice? Check the product certifications to ensure the mattress is up to par. Greenguard Gold certification indicates the product has been tested for low chemical emissions, while CertiPUR-US seal verifies that polyurethane foam meets standards for content, emissions and durability. Mitchell also recommends choosing a crib mattress that meets federal flammability standards while avoiding the use of potentially harmful chemical flame retardants when possible.
• Breathability. Breathability can help with airflow and temperature regulation, especially for babies who tend to sleep hot. Some parents also find it reassuring once baby starts rolling. That said, breathability isn’t a substitute for safe sleep practices.

Once you’ve got the features down, there’s a few more things to keep in mind:

• Use the correct side (for a dual-sided mattress). Dual-sided crib mattresses can be a practical, long-term option offering a firmer side for infants and a slightly softer side for toddlers. Be sure to follow the manufacturer’s guidelines for when to flip the mattress––and double-check that the correct side is facing up after changing sheets. Keeping the tags intact can make it easier to identify each side.
• Be careful when buying second-hand. Whether using a hand-me-down mattress or purchasing a second-hand mattress for your little one, it’s important to check its condition carefully. ”A quality crib mattress can be used for up to 5-7 years as long as it’s in good condition,” says Mitchell. “The most important thing parents should look for is to make sure the mattress is still firm and there is no damage or mold.” Always test for firmness and inspect for signs of wear, mildew or structural breakdown. If you’re unsure about its condition, it’s safest to skip it. Mitchell also recommends periodically checking updated safety guidelines from the AAP and product recalls issued by the Consumer Product Safety Commission (CPSC).
• Don’t feel like you need to overspend. A higher price tag doesn’t always equal better safety. Many affordable crib mattresses still meet key safety standards. When shopping on a budget, focus on the essentials: a firm surface, proper fit, reputable brand and trusted certifications.
