Each year, as many as 4,000 babies unexpectedly die in the US from accidental suffocation, SIDS (sudden infant death syndrome), and unknown causes. (1)

Thank you for reading this post, don't forget to subscribe!

What’s alarming is that, according to the CPSC (Consumer Product Safety Commission), they have received at least 494 incidents relating to crib mattresses, including 139 fatalities, between January 2010 and April 2021. (2)

According to the FDA (Food and Drug Administration), many of the reported deaths were of babies who suffocated on their infant sleep positioners, mattress, pillows, or various items inside their cribs. (1)

A lot of these babies were placed on their backs to sleep but rolled over and accidentally suffocated on thick materials in their sleeping environment. (1)

What kind of mattress is best for your baby, how thick should it be, and do they fit in all cribs? Is there a difference in crib mattresses, and at what age can your baby sleep on a soft mattress?

What’s The Best Mattress For My Baby’s Crib?

To reduce suffocation and strangulation risks, the “Safe Sleep” guidelines of the AAP (American Academy of Pediatrics) recommend putting your baby to sleep on a firm, flat surface such as a tightly fitting crib mattress placed in a safety-approved crib. (3)

This crib mattress should be covered by a fitted sheet, with no other bedding, blankets, or pillows placed inside the crib.

For added safety, the AAP doesn’t recommend mattress toppers in the sleeping areas of babies younger than one year.

Because they’re soft and adjustable, mattresses or mattress covers with memory foam are strongly discouraged.

Mattress size matters, depending on your crib or sleeping surface. For example, use only mini crib mattresses for a mini crib and a standard crib mattress for a standard-sized crib.

Considering that babies spend most of their time sleeping, it’s best to pick a GREENGUARD Gold-certified crib mattress. Products with this certification have low emissions of harmful chemicals, including formaldehyde and other VOCs (volatile organic compounds).

It’s also ideal to choose GREENGUARD Gold-certified furniture for the rest of your baby’s nursery.

You might also want to pick CertiPUR-US certified products which are free from other toxic chemicals (e.g., phthalates, formaldehyde, and flame retardants).

Others opt for those with OEKO-TEX certification, which means that the product is free from harmful chemicals.

Plenty of parents also prefer buying non-toxic, organic GOTS (Global Organic Textile Standard) certified or GOLS (Global Organic Latex Standard) certified products.

Factors In Choosing A Crib Mattress

Safety & Breathability: What’s The Best Thing For A Newborn To Sleep In?

SIDS (sudden infant death syndrome) is a serious risk for babies younger than one year old. So, it’s very important to keep their sleeping environment as safe as possible by following the AAP’s Safe Sleep guidelines:

  • Use a firm, flat surface.
  • A crib or bassinet is preferable for babies to have a safe space separate from older kids and adults.
  • Crib mattresses made with breathable materials are preferred.
  • Don’t put anything that could obstruct airflow or your baby’s breathing, including blankets, soft toys, crib bumpers, sleep positioners, and pillows.
  • Avoid using inclined sleepers and other products not designed for sleeping, especially those with a sharp incline higher than 10 degrees.

 

Materials & Certifications

We recommend organic crib mattresses with a GREENGUARD Gold certification because they’re tested and certified to be free from toxic fumes and emissions that could harm your baby.

Other certifications to consider:

  • CertiPUR-US certification – free from toxic chemicals (e.g., phthalates, formaldehyde, and flame retardants)
  • GOTS (Global Organic Textile Standard) – for textiles made from natural organic fibers, such as wool, cotton, silk, or bamboo 
  • GOLS (Global Organic Latex Standard) – products refined from natural rubber (e.g., latex foam mattresses)
  • OEKO-TEX certification – textiles free from harmful chemicals

 

Waterproof

These mattresses can last longer because they’re protected from various messes, but they might be less breathable. 

 

Ideal Size & Fit: Do All Crib Mattresses Fit All Cribs?

A full-size crib mattress should have dimensions of 28 inches x 52 ⅜ inches to fit snugly into the standard crib without gaps between the mattress and the crib.

A mini crib mattress should measure at least 38 inches x 24 inches.

While most manufacturers make cribs with these dimensions, some also create other sizes. However, they’re required by law to sell their products with crib mattresses that fit snugly and pass the safety standards.

 

How Thick Should A Crib Mattress Be?

Mini and standard crib mattresses should have a maximum thickness of 6 inches.

 

Firmness

A crib mattress should be firm enough to support your baby’s weight, even for prolonged sleeping periods. 

It shouldn’t sag or conform to your baby’s body the same way as a memory foam because that could obstruct airflow to your baby’s nose and lead to suffocation.

 

Adjustable Or Multi-use Options

Babies quickly outgrow their crib, but many budget-savvy parents pick a crib mattress that can also double as a toddler bed.

Many of these mattresses have two different surfaces – a softer toddler side and a firmer baby side.

 

Cost: How Much Should You Spend?

It depends on your budget. However, you can find good options available at a little over $100, such as the Sealy Soybean Foam-Core Crib & Toddler Mattress at $129.99.

If you want to splurge, the Avocado Luxury Organic Crib Mattress costs $1,379.

 

Sustainability

Some manufacturers claim that they follow sustainable manufacturing processes to ensure that they produce child-safe, eco-friendly products.

 

Crib Mattress FAQs

Does My Baby Need A Crib Mattress & Will It Make A Difference To Their Sleep?

The AAP recommends using a crib or bassinet as your baby’s sleeping space so they can have a separate place to sleep from adults or older kids who might accidentally cause them to suffocate.

A firm, flat, and separate sleeping space can reduce their risk of SIDS and help them sleep better and safer.

 

Is There A Difference In Crib Mattresses?

Yes. Different types of crib mattresses can include:

  • Foam-free, spring-free crib mattresses
  • Foam mattresses
  • Innerspring crib mattresses
  • Eco-friendly crib mattresses
  • Standard-sized crib mattresses
  • Mini crib mattresses

 

At What Age Can Babies Sleep On A Soft Mattress?

The AAP recommends the Safe Sleep guidelines for babies younger than one year old. So, once they turn one, you can start putting your baby on a soft twin mattress or flip their 2-in-1 crib mattress to the toddler side.

 

What’s The Best Way To Clean A Crib Mattress?

It depends on your crib mattress. Be sure to read their label.

Many have removable, machine-washable covers, but others can only be wiped clean with a damp cloth with mild detergent.
