What’s Inside the Colgate Eco Classica III Crib Mattress?

With the Colgate Eco Classica III, Colgate manages to take advantage of the best features of foam mattresses (they’re cheaper than other options and are lightweight) while also doing their best to eliminate the cons of many foam crib mattresses.

Foam Made from Sustainable Plant Oils

The foam in the Eco Classica III is made from sustainable plant oil foam rather than petroleum based oils. The foam is also CertiPUR-US certified, which means it’s independently tested and meets high standards for content, VOC emissions, and durability.

A Note About Durability

If you’re brand new to the parenting world, you might wonder why a mattress for a baby needs to be durable. Unfortunately, your sweet baby will have some not so sweet things come out of her as she grows. Between blowouts, spit up, jumping, and climbing, your baby’s crib mattress will take more of a beating than you’d think.

If you’re on your way to having a baby in your house, you might not yet realize how important durability is!

A Breathable Foam Crib Mattress?

In addition to using sustainable plant oils when crafting their foam, Colgate takes another step to combat some of the typical cons of a foam crib mattress: a lack of breathability.

Foam is known for being not very breathable. To deal with this, Colgate uses open cell foam and polyethylene (PE) foam with air channels to create more air circulation. This additional circulation makes the mattress more breathable and that breathability helps your baby regulate her temperature all night long. 

Researchers for the Pediatric Pulmonary Institute at Schneider Children’s Medical Center of Israel found that more breathable mattresses help prevent babies from overheating and that more breathable sleeping surfaces “exhibited significantly better aeration properties in dispersing CO(2) and in preventing its accumulation.” In other words, they can prevent your baby from re-breathing her own exhaled air. 

The American Academy of Pediatrics also noted that breathable mattresses might help prevent SIDS (although this has not yet been proven as fact).

Once your baby starts rolling on her own, all bets are off for the position she’ll be in when she wakes up —and we know how scary it is to find your baby face down when you know you placed her safely on her back. If you’re going to choose a foam mattress, you might feel better choosing a breathable crib mattress

Rayon Flame Barrier

Surrounding the foam that makes up the bulk of the mattress is a fire-resistant flame barrier made of rayon, which is a semi-synthetic material that Colgate says is natural. The use of rayon does allow Colgate to avoid the fire-retardant chemicals while exceeding federal flammability standards. There are more natural flame resistant materials Colgate could be using (wool, for example), but we’re still happy they use rayon instead of chemicals.

Organic Cotton Cover with Waterproof Backing

The soft cover on this mattress is made of certified organic cotton, and it also has a food grade waterproof backing.

The organic cotton cover is the layer of the mattress that is closest to your baby’s skin, so the use of organic material here is of utmost importance.

Colgate also offers an organic mattress cover and a waterproof mattress cover for when your little one starts potty training and needs extra protective coverage.

Colgate does not offer more specifics on what exactly the waterproof backing is made of on both the mattress itself and the separate waterproof mattress cover.  

Is It Really “Eco-Friendlier”? 

According to the Federal Trade Commission’s Green Guides, companies shouldn’t make claims of being eco-friendly because that’s a vague term that’s hard to back up. So, what does Colgate do to back up this claim? While it’s almost impossible to fully substantiate, Colgate is eco-friendlier, as they say, than many other foam mattress brands. 

The Eco Classica III (and all Colgate mattresses) are GREENGUARD Gold certified. This means they have been independently tested and found to give off very low levels of volatile organic compounds (VOCs). 

The Eco Classica III also uses CertiPUR-US foam to make it eco-friendlier. This means the foam in the mattress is independently certified as made without: 

  • Ozone depleters
  • PBDEs, TDCPP or TCEP (“Tris”) flame retardants
  • Heavy metals, including mercury and lead
  • Formaldehyde
  • Phthalates

It also means the foam is certified to give off low levels of VOCs.

The mattress is also hypoallergenic, according to Colgate. 

These certifications should make you feel good knowing your baby will be sleeping on a mattress that is better than most. However we would still like to see more transparency from Colgate.

In response to the question, “Are there chemicals in the mattress or the mattress cover that could harm my baby?” Colgate responded

“All of our materials are non-toxic. While there are specific Federal regulations that manufacturers must meet with regard to the chemicals used in raw materials, our approach has always been to not just meet, but to exceed, those regulations. For additional information on this topic, please refer to the ‘Health and Safety’ section of our website.”

Unfortunately, the “health and safety” section of their website does not clearly answer the question, either. 

Other Features

There are some additional features of the Colgate Eco Classica III that make it stand apart from other mattresses. 


Double sided crib mattresses help extend the life of the mattress. They also provide a safe and comfortable sleeping surface for babies as well as toddlers. The Eco Classica III uses eco foam on both sides of the mattress. However, the infant side is firmer than the toddler side.

Most parents flip their mattress from the infant side to the toddler side somewhere between 12 and 24 months. 

Remember, the Colgate Eco Classica iii is a 2-stage mattress. Face the firmer side up for a baby, and flip the mattress to the plusher side for a toddler.

Inverted Seam

The Eco Classica III has an inverted seam. This is an interesting feature that helps the crib mattress fit well into the crib. The feature helps it easily slide into the crib with minimal gaps. The inverted seam makes the mattress more durable, too. 


Your Colgate mattress will come with a lifetime warranty against any defects. Any mattress that doesn’t come with a warranty should raise some red flags in your mattress research. 

Made in the USA

Colgate mattresses are handmade in the United States. This is great from a supporting the local economy point-of-view. It also may result in a smaller carbon footprint related to shipping.

Family-Owned Company

Colgate is a family-owned company. Founded by lovebirds Sol and Anne Wolkin in 1955, the Wolkin family still run the company. Of course, they use Colgate mattresses for their own babies. 

Colgate Eco Classica III Crib Mattress Summary

What’s to Love

  • The Eco Classica III uses plant-oil-based foam, which seems like a better alternative than petroleum based oils. 
  • Colgate manufactures their foam to be more breathable than the foam in many other mattresses. 
  • Very lightweight at 13 pounds. 
  • The Eco Classica III meets federal flammability standards without relying on flame-retardant chemicals.
  • Certified organic cotton cover.
  • GREENGUARD Gold certification and CertiPUR-US foam ensure low levels of VOCs and the absence of heavy metals, formaldehyde, and phthalates. 
  • Dual sided mattress—firm for infants and softer for toddlers.

What We’d Change

  • Colgate is not very transparent about many of their materials, answering questions with vague responses.
  • Like many crib mattress companies, their marketing uses vague terms such as “eco-friendlier” and “non-toxic.”
  • The mattress’ cover has a waterproof backing, which is great! That said, Colgate could be a lot more clear and up-front about what this backing is made of.

I hope this overview helped you make your decision a little easier.

I don’t have personal experience with this mattress, as we use a Naturepedic crib mattress for our daughter.

However, I’ve done my best with the research to provide a thorough an overview as possible. I hope it helped!
