Best Crib Mattress Buying Guide

Safety and Firmness

The American Academy of Pediatrics recommends a firm crib mattress for infants to prevent suffocation. A mattress that is too soft can allow a baby’s head to sink in, increasing the risk of rebreathing carbon dioxide.

Look for mattresses that pass the Consumer Product Safety Commission’s firmness evaluations and are labeled as “firm.” Many top picks, such as the Tiankehan and Letmxiu models, meet these standards while still providing comfort for toddlers when flipped to the softer side.

For more on support levels, see our guide to a firm mattress.

When evaluating safety, also consider certifications like GREENGUARD Gold, which ensures low chemical emissions. All of our recommended mattresses have passed rigorous third-party evaluation for volatile organic compounds (VOCs) and other harmful substances.

This is especially important for babies, who spend up to 16 hours a day on their mattress.

Breathability and Materials

Breathable crib mattresses use open-cell foam, air channels, or mesh covers to promote airflow, helping to dissipate heat and reduce the risk of overheating.

The Newton Baby mattress, for example, features a 100% breathable core that allows air to pass through even if the baby rolls onto their stomach.

Materials also matter: organic cotton covers, natural latex, and plant-based foams are increasingly popular for parents seeking a green mattress without synthetic chemicals.

Memory foam is common in dual-sided toddler mattresses, but ensure it’s high-density and wrapped in a waterproof, hypoallergenic cover. Some brands, like Dourxi and Babelio, use gel-infused memory foam to regulate temperature. Always check that the foam is CertiPUR-US certified for low emissions and durability.

Waterproof and Easy Cleaning

Babies are messy, so a waterproof mattress is non-negotiable. Most quality crib mattresses have a vinyl or polyurethane coating that protects the inner foam from spills, diaper leaks, and spit-up.

The Sealy Baby Flex Cool and Serta Perfect Slumber models feature a waterproof cotton-like surface that is easy to wipe clean.

Removable, machine-washable covers are a bonus, the Newton Baby’s cover can be tossed in the wash, and the entire mattress core is even machine-washable for deep cleaning.

For extra protection, consider pairing your mattress with a mattress protector. This adds an additional barrier against allergens and accidents, extending the life of your mattress.

Dual-Sided Design

Many crib mattresses offer a dual-sided design: a firm infant side and a slightly softer toddler side. This allows the mattress to grow with your child, typically recommended for use from birth to about age 4.

The Dourxi and Graco Premium Foam mattresses are excellent examples, providing a supportive firm side for babies and a plush memory foam side for toddlers. When flipping, always check the manufacturer’s weight and age guidelines to ensure safe use.

If you prefer a single-sided mattress, ensure it’s firm enough for infants and still comfortable for toddlers. Some parents opt for a dedicated twin mattress when transitioning to a big-kid bed, but a dual-sided crib mattress can save money and simplify the switch.

Certifications and Non-Toxic Materials

Health-conscious parents should look for crib mattresses with third-party certifications. GREENGUARD Gold is the gold standard for low chemical emissions, while CertiPUR-US and OEKO-TEX Standard 100 provide additional assurance.

The Serta Perfect Slumber and Sealy Baby Flex Cool both carry GREENGUARD Gold certification. Some brands, like Newton Baby, go a step further with food-grade materials and a washable design that eliminates dust mites.

For a deeper dive into non-toxic options, explore our roundup of the best organic mattress.

Also consider the mattress cover: organic cotton, bamboo, or polyester blends are common. Avoid phthalates, lead, and flame retardants, all our picks comply with federal safety standards and are free from these chemicals.

Frequently Asked Questions

Is a firm or soft crib mattress better for babies?

For infants under 12 months, a firm mattress is essential to reduce the risk of SIDS. The mattress should not indent when the baby lies on it.

After age 1, a slightly softer surface is acceptable, which is why many parents choose dual-sided mattresses that offer a firm side for babies and a softer side for toddlers. Always follow the manufacturer’s age recommendations.

What does GREENGUARD Gold certified mean?

GREENGUARD Gold is a certification that ensures a product meets strict chemical emission limits, including volatile organic compounds (VOCs) and phthalates. It is particularly stringent for products used in schools and healthcare settings.

For crib mattresses, Gold certification means the mattress is safe for sensitive populations like infants and children. All our picks either have this certification or equivalent third-party validation.

How thick should a crib mattress be?

Standard crib mattresses are 5 to 6 inches thick. A thicker mattress may not fit properly in a standard crib, leaving a gap between the mattress and the crib sides, which is a safety hazard.

Always measure your crib’s interior depth and ensure the mattress height leaves at least 2 inches between the top of the mattress and the crib rail when the mattress is at its lowest setting.

Most of our recommended models are 5 inches thick, fitting standard cribs and toddler beds.

Can I use a used crib mattress?

It is not recommended to use a used crib mattress if you don’t know its full history. Older mattresses may have been recalled, may not meet current safety standards, or could harbor mold, dust mites, or bacteria from previous use.

If you do consider a used mattress, inspect it thoroughly for sagging, stains, or damage, and ensure it still has a firm surface.

For peace of mind, a new mattress with a 7-year warranty, like the Serta Perfect Slumber, is a safer bet.

How often should I replace a crib mattress?

Most crib mattresses are designed to last through the toddler years, typically 3 to 5 years. Replace it sooner if you notice sagging, lumps, or tears in the cover.

Also, if your child has outgrown the crib and moved to a twin bed, you may want to invest in a twin mattress for their new bed. Regularly check the mattress for wear and ensure it remains firm and supportive.

Are dual-sided crib mattresses worth it?

Yes, for most families. Dual-sided mattresses provide a firm infant side and a softer toddler side, extending the life of the mattress and saving money.

They are particularly convenient if you plan to use the same mattress from birth to age 4 or 5. However, if you prefer a single-sided mattress that is firm throughout, that’s also safe as long as it remains firm for toddlers.

Brands like Dourxi and Graco offer excellent dual-sided options that have been well-reviewed by parents for their durability.
