Whether you decide to move your new baby to their nursery right away, or to room-share for a bit using a bassinet or co-sleeper, the time will eventually come for your infant to sleep in a crib. As with any sleep setup, there’s a lot to consider when selecting the best best crib mattress for your child–and for many parents this includes concerns about chemicals and off-gassing. Thankfully, a ton of great non-toxic crib mattresses exist, so you can sleep easier knowing your child is in the safest scenario.

While tons of brands label their products as nontoxic, it’s a pretty vague statement without the proper certifications. Luckily, there’s a few hacks for finding the best non-toxic crib mattresses. Tasha Stoiber, Ph.D., a senior scientist at EWG, suggests looking for a company that values transparency to start your shopping process, calling it one of the “most important things” a parent can do. She explains that if a company is transparent about the materials it uses and how they’re sourced, “then you know exactly what you are getting and can avoid harmful materials.”

Below, find more expert advice on what certifications to look for in a crib mattress (and which materials to avoid)–plus, shop our picks for the best non-toxic crib mattresses of 2022.

What is a non-toxic crib mattress?

As the name implies, a non-toxic crib mattress poses a low risk of releasing toxins. In particular, this centers around off-gassing, a common scenario in which manufactured items slowly release volatile organic compounds (VOCs) into the environment as they air out over time. VOCs are often created during the manufacturing process, and can be formed in the foams, fabrics, or plastics used in many standard mattresses.

In truth, most items in your home release VOCs, including electronics, clothing, carpeting, furniture, wall paint, and appliances. That said, inhaling elevated levels of VOCs can be particularly irritating for some–namely young infants or people with compromised respiratory systems, or known chemical allergies.

“Volatile organic compounds are harmful to both short-term and long-term health,” Stoiber explains. “In the short term, they can be linked to respiratory irritation and increased asthma symptoms. In the long-term, they are linked to more serious health harms, such as cancer. They are more common in mattresses made with polyurethane foam.”

The importance of non-toxic certifications

Non-toxic certifications are provided by third-party oversight organizations that test the brand’s products, to confirm that the VOCs being emitted are low enough to not pose a risk of encouraging respiratory complications or allergies. The most common certifications for mattresses are GREENGUARD, CertiPUR-US, and GOTS.

A mattress may carry more than one certification, especially given that some oversight agencies only focus on one or a few select materials. For example, it’s common to see brands featuring both CertiPUR-US and GOTS certifications. CertiPUR-US reviews the foam and GOTS checks other materials such as a mattress’s cotton cover–so if a product uses both foam and cotton, it’s important to have the two stamps of approval.

To that point, Stoiber advises to “Make sure that the whole mattress is certified, and not just one part, like the cover.” She also notes that CertiPUR-US on its own is not particularly meaningful, as “It actually doesn’t provide much protection beyond what is already required by law.”

Types of non-toxic certifications


GREENGUARD is the certification organization managed by Underwriters Laboratories (UL), and is considered the most rigorous. UL has some of the strictest testing standards across all products, and requires the lowest VOC emission limits for all materials present in mattresses submitted for review.


CertiPUR-US is a certification focusing specifically on polyurethane foam VOC emissions, making this certification important for foam and memory foam mattresses. This organization also reviews emissions for flame retardants, formaldehyde, phthalates, mercury, lead, other heavy metals, and other VOCs. But again, Stoiber explains that this certification on its own does not hold much significance.


GOTS grants organic and low-chemical processing certification for textiles. To achieve the GOTS Certified Organic label, the fabric content for a product must be made from 95% organic fibers. Additionally, during the production process, the manufacturer must adhere to strict guidelines regarding the types of chemicals used (i.e. dyes, processing agents, etc.), and may not use harsh chemicals, such as formaldehyde, genetically modified organics (GMOs), or toxic heavy metals.

Peace of mind is essential when you’re shopping for your baby–and with a mattress that features 100% GOLS certified latex, 100% GOTS organic certified cotton, and is also UL-certified formaldehyde-free, you’ll get exactly that.

The brand prioritizes sustainability, and ships its mattresses in a recyclable paper box, with a shrink-wrapped recyclable plastic cover.

Sizes Available: Standard size

Trial Period: 30 nights

Warranty: 20-year

How It’s Made & How It Arrives:

While it’s one of the more expensive options on our list, this mattress is made with high quality materials and holds up well over time. The mattress is GOLS certified, with an organic latex core wrapped in a breathable, organic wool and cotton cover. It offers extra-firm support and is free from chemical fire retardants. Another flippable model, the brand recommends rotating this mattress regularly to minimize wear and tear.

While it does arrive folded in its box, it is ready to sleep on once unwrapped and set up. Most people do not experience an off-gassing smell.

What Customers Say:

This mattress is one of the rare finds that offers a full five out of five-star review overall. One reviewer shares, “My little one is currently two years old and has been happily sleeping on the mattress for just over a year and half. The mattress is still in amazing condition – we purchased a wool cover for protection and flip it over periodically.”

Keep in mind, it’s on the thinner side at only 3.5 inches wide, so it may not be a great fit for all cribs.

How to Choose

Given many of the warnings parents receive regarding baby safety, picking the right crib mattress can be daunting. The following criteria will help you make an informed decision.


Crib mattresses are typically categorized the same as those for older children and adults: innerspring, memory foam, latex, or hybrid (blend of multiple materials). Parents that want a fully organic or natural mattress should look for natural latex or organic mattresses. Again, you’ll want to look for GOTS or GOLS certifications in addition to GREENGUARD Gold as both GOTS and GOLS refer to organic and natural materials classifications.

Memory foam tends to experience the most off-gassing. So, if you want a memory foam or foam-based mattress, be sure that it at least carries a CertiPUR-US certification.

“Some mattresses that you can order online have substituted fiberglass as a cheaper alternative to chemical flame retardants,” Stoiber explains. She goes on to say that “There are concerns that the fiberglass can migrate out of the mattress, especially if you take the cover off. Exposure to fiberglass can lead to skin and respiratory irritation, rashes, as well as damage to the home and property.”

Again, Stoiber stresses the importance of transparency, adding that “It’s a red flag if the company won’t disclose exactly what they are using.”


If your focus is a non-toxic crib mattress, you can’t ignore certifications. At a bare minimum, you want a mattress with GREENGUARD certification. This is considered the top option, as it’s backed by UL–which is considered one of the most comprehensive oversights and standards independent organizations in the United States. And again, for foam mattresses, look for a CertiPUR-US certification at an absolute minimum. When it comes to organic textiles and fibers, prioritize those with GOTS, GOLS, or OEKO-TEX certifications.

While there are other certification organizations, those listed above are the most common and reputable. Just remember, certification doesn’t mean that no off-gassing occurs. These labels simply mean that the amount of VOCs released is lower than the levels considered hazardous by the Environmental Protection Agency (EPA) or the Occupational Safety and Hazard Administration (OSHA).


Research shows that a firmer mattress will reduce the risk of Sudden Infant Death Syndrome (SIDS), so if you’re strictly buying a mattress for the crib stage, you’ll want a firm option.

Dual-use mattresses (flippable models with an infant and toddler side) have different firmness levels on each side–with the toddler size being a bit softer. These mattresses are a great option for parents who don’t want to swap out models in just a couple years.


The longevity of a crib mattress is significantly shorter than other mattresses. Usually, you’ll find that manufacturers outline an age or weight limit. At a minimum, your crib mattress should be compatible from newborn through three years of age.

As mentioned, the flippable models will provide more durability and a longer shelf life.


Crib mattresses can vary widely in price. Consider your budget and the number of years you’ll get out of the mattress you choose.


The last thing you want is a crib mattress that’s too small for the crib, sits up too high even when the crib is set to the lowest position, or that’s on a recall list. So, be sure to measure the interior dimensions of your crib (especially the height).

Keep in mind that eventually, your baby will begin to pull themselves up on the sides of the crib. So, if the mattress is too tall, this creates a hazard where your child may be able to bend over the sides and fall out. Of course, always check the CPSC recall list to be sure that your intended mattress isn’t listed.


Look for features like machine-washable, waterproof, and/or stain-resistant covers, to make upkeep much easier and protect the core of your child’s mattress from getting soiled or damaged. Alternatively, if you pick a mattress that doesn’t have those built-in features, you can invest in a crib mattress cover.


What is a non-toxic crib mattress?

A non-toxic crib mattress emits low levels of VOCs during the off-gassing process, or doesn’t rely on harsh chemicals and additives during the production process. To ensure you’re picking a non-toxic crib mattress, look for options that carry certifications from trusted oversight organizations such as GREENGUARD, CertiPUR-US, GOTS, or GOLS.

What mattress material is best for babies?

“Infants are in a critical stage of development and may be more susceptible to chemical exposures,” Stoiber explains. Since waterproofing is important for crib mattresses, she advises looking for a mattress that uses polyethylene, which she says won’t off-gas as much as polyvinyl chloride, which is used often for waterproofing.

The takeaway.

With so many options available, it can be difficult to choose the best crib mattress for your toddler–and once sustainability and safety enter the equation, the decision becomes even more confusing. Non-toxic crib mattresses help minimize the risk of allergic reactions or respiratory irritation caused by a mattress. To save yourself a headache and ensure that your child has a healthy, restful sleep, try one of these options or check for the certifications we mentioned.
