Colgate Eco Classica III Crib Mattress Review

We love that you can use the mattress from infancy to toddler years, but the lack of complete information regarding the materials used makes us uncomfortable.

You might think of toothpaste when you think of Colgate, but don’t be misled. The Colgate Mattress Atlanta Corp is not only unaffiliated with the worldwide dental and oral care brand, but has also been around for over 60 years! Founded in 1955 by married couple Sol and Anne Wolkin, Colgate Mattress Atlanta Corp was and has remained a family affair; the company is currently run by the Wolkins’ children and grandchildren. With a noticeable focus on high quality sleep products for infants and toddlers—the company is known as “The Crib Mattress Specialist”, after all—it’s easy to see how the Colgate Eco Classica III came to be. But what is it about this product that makes it to popular? It remains a standout crib mattress even among other similar offerings in the company’s product line. Read the review below to find out all about the Colgate Eco Classica III.


The Colgate Eco Classica III has all the typical marks of a good crib mattress. It carries both GREENGUARD Gold and CertiPUR-US certifications, and is compliant with the CPSIA (Consumer Product Safety Improvement Act of 2008), as well as state and federal flammability requirements. No fire retardant chemicals are used on the fire sock, only natural cotton fabric. However, the Colgate Eco Classica III isn’t marketed as an organic product! The company refers to it as an “eco-friendlier” crib mattress, apparently for transparency purposes. In the official website, Colgate Mattress notes that there is no industry-wide standard for what qualifies as a product that can be called natural or organic.

One of the major selling points of the Colgate Eco Classica III is that it is designed to be durable, with inverted seams, and is meant to be used by your child from infancy to well into the toddler years. The two clearly marked sides are of different firmness levels for exactly this purpose; the extra firm side to better support infants, and the less firm flip side to provide more comfort to toddlers.

What’s Inside?

The crib mattress contains two layers of what the company calls “eco foam”—one extra firm and the other less so, as explained above—which is said to be made with sustainable non-food plant oils. While we trust the certifications given to the Colgate Eco Classica III, we do have qualms about the vague description of its main component. Given that Colgate Mattress puts a premium on transparency, this is a little disconcerting. There are other mattress companies that provide more information on the eco-friendly materials used in their products! We know, for example, that similarly marketed products may use soybean oil-based polyurethane foam, or natural latex made from rubber tree sap. We’ve also found published research on the viability of plant oils being used in foam manufacturing. “Eco foam” is possible, yes; but it’s not enough to just call it that.

The two layers are enclosed in a fire sock, and then a non-removable “certified organic cotton cover”—although it is not clear where this organic certification comes from. We looked for the certification logo Colgate Mattress used, and we couldn’t find a match anywhere online. Also worth noting that this cotton cover is waterproof-backed—which also helps prevent unwanted bed bugs and dust mites from being anywhere near your child—but again, the materials used for this part aren’t specifically stated, although the company notes that it is food-grade and hypoallergenic.


The Colgate Eco Classica III is just one crib mattress out of dozens that Colgate Mattress has developed and made available commercially over the years. If you’re looking for something a little different—like gel memory foam or maybe even a hybrid innerspring and foam variant—chances are you’ll find what you’re looking for among the company’s other offerings. Should you stick to Colgate Mattress, one great advantage is that they also make mattress pads, covers and other accessories; which are likely to all be compatible with the Colgate Eco Classica III or whichever mattress of theirs you end up choosing.

What Can Be Used with It?

The size of crib mattresses is regulated by the Federal government by the CPSIA, of which–as mentioned previously—the Colgate Eco Classica III is compliant. This means that any standard crib can be used with the Colgate Eco Classica; it should fit snugly, especially with its square corners. If you’re not sure if your crib is standard, do perform the two finger test to check if there’s too much space between the mattress and the crib. Any more than the width of two fingers and your crib frame and mattress aren’t compatible! Change one of the two to avoid possible entrapment or suffocation. Some reviews online have also mentioned that it doesn’t work with baby motion monitors, so keep that in mind.

How Easy Is It to Set Up and Clean?

The crib mattress comes in simple, frustration-free packaging. No hard plastic, no brightly colored box, no triple- or quadruple-layered material covering the product; just a plain brown box and the Colgate Eco Classica III wrapped in plastic that’s easy to take off. While we did have some questions about the make and design of this crib mattress, we’ve found no widely publicized reports or reviews of the product off-gassing or inciting allergic reactions.

The Colgate Eco Classica III is also lightweight at just under 10 pounds, which makes changing sheets a breeze. Because the mattress cover is non-removable—although soft and waterproof—we do recommend that you use separate washable sheets, just to make life easier. Doing this will lessen the chances of keeping the mattress completely clean; as organic cotton, even with waterproof backing, does still stain. If you need to clean the crib mattress itself, stop cleaning with a damp cloth and mild soap works.

What’s the Weight Capacity?

There is no specific weight capacity listed on the official website, but as the crib mattress is marketed as durable and for use by toddlers, we’re going to assume that this means it can support up to at least 35 pounds—which is about the average weight of a three-year-old. We’ve reached out to Colgate Mattress to ask about this particular bit of information, and will update this section accordingly.

How Does It Feel?

It feels firm—the way it’s supposed to feel if it’s going to be used by an infant. Some reviews we’ve seen have mentioned that the extra firm side was too firm; but that is exactly the point. An infant is not supposed to sleep on a surface that may be too soft and pressure relieving, because that’s a health hazard. The slightly softer, toddler side is still firm but not as much; although again, we’ve seen reviews that note that if it weren’t for the clear markings, they’d never know the difference between the two sides.


There’s a lot to like about Colgate Mattress. It’s easy to feel at ease with a company that’s family-owned and family-operated, especially it’s been in the business for more than half a century. That the products are made and handcrafted in the US is also a nice touch. However, it’s really the fact that the Colgate Mattress product line is so well-developed and well-populated that does the job of convincing us that this company is one to be trusted. Yes, some of the fine details may be missing from the official website and the press releases—the FAQ leaves a lot to be desired—but there is a lot of information on the company’s sustainability practices and its history. Coupled with the numerous products that are all infant- and toddler-focused, it has us believing that Colgate Mattress is a company that truly cares about its customers and the quality of the products that they provide.

That being said, we have looked at product reviews online extensively, and while there is an overwhelming amount of positive feedback regarding the Colgate Eco Classica III, it’s not all good. Negative feedback—complaints about product quality, questions about materials and constructions, and more—seems to be cropping up particular for recent purchases. We’ve seen reports of people buying their second or third Colgate Eco Classica III, and then complaining that they didn’t get the same product at all. The common complaints seem to involve the stitching and the mattress cover fabric, as well as not being able to tell which side is which.

How Easy Are Returns? How Good Is the Warranty?

There is a return policy and a 90-day money back guarantee, but this offer stand only for orders placed with Colgate directly. This is important! If you get a Colgate Eco Classica III from another retailer, their respective return policy is the one that will be followed. There’s also a replacement policy for products damaged during shipping, but there is a clear procedure you need to follow to avail of this. Check the official website for more information.

There is a limited lifetime warranty. The conditions are typical: Non-transferable and only honoring the original owner with proof of purchase, covering only workmanship or material defects, and not covering regular wear and tear. This means that you can’t use the warranty should the mattress cover get stained or the mattress get warped due to undue physical strain or abuse.


The Colgate Eco Classica III is available on the official website for $219.99, as of this writing. Free standard shipping is offered to the 48 contiguous US states. Expect the product to arrive within a week. This price point is about average for high quality, innovative crib mattresses—but a little but too much, in our opinion, for a product without a trial period and without a truly unique aspect to its design. Worth noting that the Colgate Eco Classica III is also available—sometimes for a more friendly price—at online retailers like Amazon.


This product is obviously well-loved and well-reviewed, but we admit that we’re a little mystified now that we’ve dug deeper to find out why. There is nothing wrong with it, really. It’s not marketed as organic—just “eco-friendlier”—so technically it’s not a big deal if it’s not exactly completely biodegradable or devoid of synthetic material. Even in negative reviews, we didn’t find any mentions of allergic reactions or off-gassing complaints. The mattress cover does its job well, in that it is waterproof enough to prevent fluid from getting into the foam component; and we didn’t find any complaints about heat retention or breathability problems. Here’s the thing, though: For a product that’s basically a foam mattress with a waterproof cover, the price point is just a little bit too high; even for being dual-sided. However, it can be worth it if your child does use it until the end of their toddler years—especially if you also use other compatible products from Colgate Mattress.
