Are you concerned about toxic chemicals in your nursery? Looking for a solution that will protect your crib mattress from leaks, but also (more importantly) keep your baby safe?

As a father of two and a proud new uncle, I share your concerns. 

My family and I don't allow any toxic chemicals near our little ones. That's why we've been busy testing the best organic crib mattress pads on the market that are made from natural fibers.

Today I share my top picks to help you find an affordable waterproof pad that will keep your baby's mattress dry, without harming your budget or your family's health.

What are the Top Organic Crib Mattress Pads of 2024?

Quick Picks

  • Certifications: GOTS, GREENGUARD Gold, Formaldehyde Free, MADE SAFE®, PETA-Approved Vegan
  • Materials: GOTS-Certified Organic Cotton, Non-Toxic Waterproof Membrane
  • Size: Fits standard-size crib mattresses (28" x 52" x 8")
  • Sleep Trial: 100 nights
  • Warranty: 1-year

This is a high-quality, eco-friendly crib mattress pad at a very reasonable price. It feels tough and durable, but also soft and comfortable against sensitive skin. 

The waterproof barrier is highly effective at keeping the mattress completely dry without any leakage, provided you follow the care instructions carefully to maintain its performance over time. I recommend you wash it before first use, as it shrinks to fit. After doing so, it goes over any standard-size crib mattress easily, just like a fitted crib sheet.

Like most waterproof pads, this contains a very thin polyurethane film layer which is required for waterproofing. I appreciate this is never ideal from an environmental perspective, but it does only represent a very small percentage of the total content.  There is no way to achieve the full waterproofing effect without it, so a compromise has to be made.

The good news is that the film layer is fully certified non-toxic and contains no PVC, phthalates, or vinyl. It's also breathable and 100% crinkle-free, so your baby gets a cool, undisturbed and safe sleep - guaranteed.

Taking everything into account, this is my favorite of all crib mattress pads I've seen. Customers love it, and you won't find a better product for the price.

  • The product is worth the price
    It's very well made and the material is superb. I wanted something that made sense for our son and the first one we purchased two years ago looks like new still just had to get an extra one. Buy two!

When testing the Naturepedic organic waterproof crib cover I was particularly impressed with the innovative design of its breathable 3D mesh layer.

It offers exceptional air circulation, which significantly reduces the risk of overheating for infants, a crucial safety aspect often overlooked in traditional crib covers. This mesh layer is uniquely paired with an organic cotton cover, offering a soft, gentle surface that's ideal for a baby's sensitive skin.

The cover's waterproof functionality, achieved with a non-toxic polyurethane barrier, protects against spills without compromising on breathability. Again, while polyurethane is not perfect from an environmental point of view, it does serve to maintain a dry, hygienic sleep environment while avoiding the use of harsh chemicals often found in conventional waterproofing.

There are options to fit various crib sizes, including standard, mini, and specific models like Stokke Sleepi and HALO BassiNest.

Adding the Naturepedic organic cotton mattress cover to your baby's sleep surface can make any crib mattress breathable, even if it was not so originally. The peace of mind you'll get from that feature alone makes it a worthwhile investment in my view.

  • Certifications: GOTS, Climate Neutral, GREENGUARD Gold, 100% Certified Vegan
  • Materials: 95% GOTS-certified organic cotton and 5% waterproof polyurethane film.
  • Sizes: Fits standard-size crib mattresses (28" x 52" x 8")
  • Sleep Trial: 100 nights
  • Warranty: 1 year Limited

Brentwood Home has come up with a very attractive waterproof fitted crib pad. It boasts an incredibly soft organic cotton layer, which also offers a degree of natural breathability.

The waterproof feature of these mattress pads is efficiently executed with a thin polyurethane film. Unlike bulkier waterproof layers in some other products, this thin layer doesn't detract from the overall feel of the mattress. It provides excellent protection against spills and accidents, without the use of harmful chemicals like PVC or phthalates.

Another commendable aspect is the product's eco-friendly certifications. The GOTS certification assures that the cotton used is organic and sustainably sourced. Climate Neutral certification, which is found across the brand's products, demonstrates a commitment to reducing carbon emissions. 

From a practical standpoint, the pad's machine washability is a significant advantage for busy parents. It simplifies the often daunting task of keeping baby items clean. The pad fits standard-sized crib mattresses well, and it doesn't make noise if your baby moves around while sleeping.

  • Certifications: GREENGUARD Gold, GOTS
  • Materials: Organic cotton top and bottom layer, with a sustainably made polyurethane moisture barrier.
  • Sizes: 52 x 28 x 8
  • Sleep Trial: None - 1-week return window
  • Warranty: 1-Year

This waterproof mattress pad is the same product as the adult version but comes in crib mattress size.

The standout for me is that the thermoplastic polyurethane used in the thin waterproof barrier is made from natural and renewable materials such as non-GMO corn. It's GOTS-approved and sourced from OEKO-TEX certified suppliers, so you know it's 100% safe for your nursery.

The top and bottom layers are made from organic cotton and feel just as soft to the touch as the Avocado and Naturepedic pads. However, it lacks the temperature regulation that these products offer.

These mattress pads are machine washable and can go in the tumble dryer on low heat. However, the manufacturer states that repeated washing weakens the water-resistant barrier, so it is recommended to only do this when necessary.

One final aspect in which this product compares unfavorably is the sleep trial (there isn't one). So if this is important to you, the Avocado, Naturepedic, or Brentwood crib pads would be a better choice.

That said, the customer feedback is overwhelmingly positive and this is a good quality crib mattress pad at a decent price.

  • Certifications: GOLS
  • Materials: Bamboo, Organic Cotton
  • Sizes: Crib 52" x 28" | Bassinet 30" x 15" | Mini Sleeper 31" x 18" | Cradle 36" x 18" | Portable 36" x 26" | Playard 38" x 26" | All available in 3" or 2" Thickness
  • Sleep Trial: 90-Day Refund / Replacement
  • Warranty: Not Specified

This 100% organic latex crib mattress topper comes with a choice of organic bamboo, cotton, or wool covers. It also comes in the widest range of sizes of any brand I tested. If you need an organic mattress pad for a bassinet, cradle, or mini-sleeper then this is the brand for you.

The comfort level is second to none. If you've ever used an adult mattress topper, you'll know how transformative it can be. If you're trying to solve the problem of your baby or toddler waking too often, or suffering restless sleep due to an old or uncomfortable crib mattress, then this is the answer.

Note that this is a fully organic crib mattress topper. It's certainly easy to clean and maintain. However, I would describe it as water-resistant rather than waterproof. There is no water-repellent layer, so you may want to add a cover to stop liquids from soaking through to the mattress in the event of a severe spill or diaper leak.

Because it's a topper rather than a pad, and because it's fully organic, this product is the most expensive I've recommended here. You can find cheaper supposedly organic bamboo crib mattress pads on Amazon from brands like Baby and Brooke, but those are made in China and don't carry any trusted certifications, so I cannot recommend them.

If you have the budget, I would certainly recommend this topper either as a standalone solution or in addition to a waterproof crib mattress pad or fitted sheet.

If you're struggling to get your baby to sleep, you'll find it's worth every penny.

What is a Crib Mattress Pad?

A crib mattress pad is an additional protective layer that sits on top of a baby's crib mattress. Its primary functions are to:

  • Protect the mattress from wetness and stains
  • Add a layer of cushioning for comfort
  • Protect your baby from allergens and bacteria that can get trapped in the mattress

The pads are usually designed with elastic edges to keep them in place.

Why Buy an Organic Crib Mattress Pad?

If you've already invested in a quality organic crib mattress, is there any need to add a crib mattress pad as well?

While not essential, there are several benefits. An organic waterproof mattress pad helps protect your crib mattress and your baby's health in several ways:

  1. Non-Toxic: Free from harmful chemicals and synthetic materials, reducing potential health risks for babies and toddlers.
  2. Hypoallergenic: Ideal for sensitive skin, minimizing allergic reactions and irritations, and protecting against dust mites and bed bugs.
  3. Eco-Friendly: Made from sustainable resources, promoting environmental responsibility.
  4. Breathable: They offer better air circulation, helping regulate the baby's temperature and preventing them from overheating.
  5. Durability: Often more durable than synthetic alternatives, providing long-term usage.
  6. Comfortable: Organic fabrics like cotton or wool are more comfortable, don't cause itches or rashes, and help your baby get a better night's sleep.
  7. Waterproof: Advanced waterproofing technologies protect the mattress from spills and urine leaks.

How to Choose a Crib Mattress Pad: Buyer's Guide

Need some help choosing a crib mattress pad for your baby's nursery? Here's a quick checklist of what to look for and what to avoid.

What to Look For

  1. Organic Materials: Choose pads made mostly from organic cotton, wool, latex, or bamboo. These have been grown without chemical fertilizer or pesticide, which you wouldn't want next to your baby's skin.
  2. Waterproof: To achieve waterproofing, it is necessary for brands to include a thin plastic membrane in the center. This waterproof layer should be no more than 10% of the total material content.
  3. Certifications: Look for certifications like GOTS, OEKO-TEX, or GREENGUARD Gold for quality and safety assurance.
  4. Hypoallergenic: This isn't an essential feature, but is beneficial for sensitive skin and protection against allergens.
  5. Firmness and Fit: Ensure it fits snugly to the size of your baby's crib mattress, and provides firm support.
  6. Breathability: Many baby products are marketed as breathable, but to be so they need to allow airflow to circulate through the mattress so your baby can still breathe even if they roll over face-down while asleep.

What to Avoid

  1. Harmful Chemicals: Steer clear of pads with synthetic material, flame retardants, phthalates, PVC, or high VOC emissions.
  2. Poor Fit: Avoid pads that don't offer a snug fit as they can come loose during a night's sleep.
  3. Non-Breathable Materials: Avoid synthetic fabrics or any designs that hinder air circulation.
  4. Lack of Certifications: Be cautious of products without any safety or environmental certifications. Greenwashing is rife, so if a product is marketed as chemical-free or organic, don't just take their word for it. Make sure it is certified by a recognized authority.

Frequently Asked Questions

Is it safe to use mattress pads in a crib?

Yes, it is generally safe to use a baby mattress pad in a crib, but there are important safety considerations.

The mattress pad should fit snugly and securely around the mattress to prevent any loose fabric that could pose a suffocation hazard.

It's also crucial to ensure the pad doesn't make the sleep surface too soft, which could be unsafe for infants.

Opting for a firm, waterproof mattress pad made from non-toxic materials is recommended for both safety and hygiene. Always follow manufacturer guidelines and safety standards for baby crib bedding.

Is an organic crib mattress necessary?

Organic crib mattresses are not strictly necessary, but they offer benefits that appeal to many parents. They reduce the baby's exposure to chemicals while sleeping, and are also often hypoallergenic and environmentally friendly.

However, the key factor in any crib mattress is safety, particularly firmness and fit. Non-organic mattresses can also be safe if they meet safety standards and are free from harmful chemicals. The choice depends on personal preferences, values, and budget.

What type of mattress pad is safest for babies?

Organic mattress protectors and pads are the healthiest choice for babies and adults alike.

What is the best material for crib mattress protectors?

Organic cotton or organic bamboo are both perfect crib mattress pad materials.

What materials should be avoided in a crib mattress?

Synthetic materials like PVC, vinyl, and polyurethane foam should all be avoided. According to NJ.gov:

PVC contains dangerous chemical additives including phthalates, lead, cadmium, and/or organotins, which can be toxic to your child's health.

What is the difference between a crib mattress pad and a cover?

In practice, the terms are used interchangeably, and "crib mattress cover" could be used to describe crib mattress protectors, pads or toppers. But strictly speaking, there is a difference.

A crib mattress pad is a protective layer placed on top of the mattress, often quilted and padded for extra comfort, and usually waterproof to protect the mattress from spills and accidents.

A mattress cover is primarily designed to encase and protect the mattress. It might not have the additional padding that a pad offers but still serves to shield the mattress from dirt, dust, and allergens.

Both are used for hygiene and longevity of the mattress but differ in thickness and additional comfort features.

The Final Word

Synthetic materials can and do emit harmful chemicals into the air, and create an unsafe environment for your baby just when they're at their most vulnerable. So it's an understatement to say that keeping them out of your nursery is a good idea!

But at the same time, accidents happen. When your baby spends most of the day in their crib, you won't have the time or inclination to clean their mattress on a daily basis.

Organic crib mattress pads offer the waterproof protection you need, without compromising on safety. They may cost a few bucks more than vinyl or plastic alternatives, but the benefits are huge and undeniable.

I always buy organic whenever possible, and I hope my recommendations help you pick out the perfect option for your family.
