2. Newton Baby Cot Mattress And Toddler Bed

Let's take a look at this 100% breathable and washable cot mattress by the Newton Store. Low on VOCs, latex, and allergens, pediatricians swear by the quality and reliability of this award-winning baby's cot mattress.

Standout Features:

  • Breathe-Thru Technology
  • Certified by Greenguard Gold

Why Did We Like It?

The first feature that caught our eye was the Breathe-Thru Technology that curbs any chances of CO2 rebreathing and suffocation. And as the breathable cover is completely washable, all you have to do is zip it open and toss it in the washing machine.

Comfort is also not compromised with the natural, chemical-free viscose cover, which facilitates temperature regulation and reduces moisture retention. This makes the product the right cot mattress for hot sleepers.

Lastly, the Newton Store prioritises your baby's sleep and health by using low allergenic materials for manufacturing this baby cot mattress.

What Could've Been Better?

Considering the various positive features, we think the high price tag of this cot mattress is justified. However, some users have complained about an initial odour, which may or may not be toxic.

If you notice the same with your purchase, we recommend washing it. If the odour persists, you can contact the friendly customer care team.


  • Breathable material
  • Removable and washable mattress cover
  • Contains low VOCs and other harmful elements
  • 100% recyclable fabric
  • Temperature control


  • Expensive
  • May emit an initial odour

3. Giselle Bedding Pocket Spring and Memory Foam Mattress

With its 11-layer structural design, this 13 cm thick cot mattress provides the best of comfort and convenience. Also, the brand has incorporated aloe vera knitted fabric in the bed cover for enhanced air circulation.

Standout Features:

  • Egg-shaped massaging foam
  • Double-sided cot mattress

Why Did We Like It?

Right off the bat, babies will enjoy the thick and firm construction of this cot mattress that features an egg-shaped foam. This design offers a soothing massaging experience that will put your baby to sleep in a jiffy!

The aloe vera knitted fabric cover further ensures your baby's good health as it is highly breathable and hypoallergenic. And since the mattress is neither too soft nor too firm, it offers just the right amount of plushness and support for their tiny, sleepy bodies.

Finally, all of us know that babies tend to answer nature's call without prior warning. Thus, stains on the mattress are bound to happen. However, that won't be a problem with this non standard cot mattress which can be used on either side.

What Could've Been Better?

In all honesty, we could not point a finger at any drawbacks of this baby cot mattress. However, we recommend testing it before buying as the egg-shaped foam may not be everyone's cup of tea. Although it offers pressure relief and spinal support, you wouldn't want to buy something only to have your baby crying with discomfort in the middle of the night.


  • Thick and comfortably firm construction
  • Contours naturally to provide support and pressure relief
  • Breathable and hypoallergenic mattress cover
  • Convenient double-sided use


  • Contoured foam may be uncomfortable for some

4. Numu-roo Breathable Cot Mattress

Numu-roo is one of the best mattress manufacturers in Australia, and this baby cot mattress stands true to its brand reputation. Besides being a comfy addition to your baby's cot beds, this mattress meets the Australian standard of safety and health.

Standout Features:

  • Partnered with Sensitive Choice
  • Meets Australian safety standards

Why Did We Like It?

This baby mattress is designed to facilitate easy breathing no matter your infant's sleeping position. As a result, it reduces CO2 rebreathing and other risk factors that may cause Sudden Infant Death Syndrome (SIDS).

The materials used in the mattress are backed by the National Asthma Council of Australia, implying that it is the best cot mattress for babies suffering from breathing issues, allergies, eczema, and more. Also, the mesh mattress cover wicks moisture and controls body heat to ensure a cool and comfortable sleep.

You will also appreciate the 100-night sleep trial, which allows you to be completely sure of the purchase before committing to it. The brand even offers a 3-year warranty period, making this mattress a definite bang for your buck!

What Could've Been Better?

Although not a deal-breaker, the assembly process of this Numu-roo cot mattress is quite challenging for beginners. With plenty of parts to deal with, users may require at least an hour to unpack and use the mattress.

However, you will be relieved to know that the official website shares illustrated instructions along with a video tutorial to help you with the process.


  • 100% breathable
  • Moisture-wicking and temperature control technology
  • Repels dust mites and allergens
  • 100-night trial period
  • 3-year warranty


  • Tedious assembly process

5. Ecosa Cot Mattress

Ecosa aims to provide parents with the peace of mind of knowing that their little ones are sleeping comfortably, so they can too. It achieves this by manufacturing supportive cot mattresses that can be adjusted as your kids grow.

Standout Features:

  • Complies with AS/NZS Voluntary Standard
  • Food-grade polypropylene construction

Why Did We Like It?

First off, Ecosa provides same-day delivery in metro cities across Australia, making it the go-to option for many. For other cities, the delivery may take 2-7 days, depending on the location.

Moving on to the design, the cot mattress meets the AS/NZS Voluntary Standard and provides just the right amount of firmness to support an infant's body. Plus, its Innovative Nestflow Core is paired with a lightweight cover, both of which are highly breathable and cool to sleep on.

We also like how it's not just the cover but also the entire mattress that allows easy cleaning. So, you can simply remove the outer cover for a machine wash while the mattress can be washed in the bath.

Finally, like all of Ecosa's mattresses, this product dons adjustable layers which provide comfortable support for growing spines.

What Could've Been Better?

This firm mattress is certified to provide the recommended firmness for infants. However, not all babies are the same, so we recommend taking advantage of the 100-night sleep trial. Also, keep in mind that the mattress firmness does not relate to its comfort level.


  • One of the best firm mattresses for infants
  • Completely washable cot mattress and cover
  • 100-night trial period
  • 5-year warranty
  • Adjustable mattress layers


  • May be too firm for some

6. Milari Green Baby Mattress

There's no way we could leave without mentioning this luxurious baby mattress by Milari Green. Made of certified organic cotton, pure latex and coconut coir, you can use the cotton side for infants and flip over to the latex side as your little ones grow up.

Standout Features:

  • 2-in-1 design
  • Eco-friendly construction

Why Did We Like It?

If you want to make an environmentally conscious purchase, this Milari Green Baby Mattress is the right pick. This luxurious yet affordable cot mattress consists of organic materials like cotton, coconut fibre, latex, and 100% Australian wool. This concoction not only makes the mattress extremely soft and plush but also ensures a safe and non-toxic sleeping environment for your baby.

Interestingly, the cottony side offers more breathability, suitable for infants, especially those who tend to roll over. Contrarily, the latex cushioned side of the mattress can be used for growing toddlers, saving you from yet another purchase.

The bamboo cover further boosts the temperature control properties and the comfort level of the mattress. It is easy to remove and wash, making it a convenient outer cover.

Furthermore, Milari Green offers a 2-year limited warranty on the pebble outer cover and a 5-year warranty on the mattress core.

What Could've Been Better?

This organic cot bed mattress has a lot to offer for infants and toddlers. However, we do feel that it is quite steeply-priced. So, if you are on a tight budget, you might want to look at other options instead.

But, do keep in mind that the advantages of this mattress easily outweigh this minor issue. Plus, since it sports a 2-in-1 design, you can consider it a valuable investment for growing kids.


  • Made of natural, non-toxic materials
  • Firm breathable side for infants and contoured latex side for toddlers
  • Easy cleaning and maintenance
  • Adequate warranty period
  • Cool and comfortable bamboo outer cover


  • Expensive

Buyer's Guide

Of course, there are plenty of top-notch cot mattresses to choose from. But making the right choice requires more than just skimming through the popular brands.

After all, a good quality mattress can ensure a regular sleeping cycle for your baby, which ultimately results in healthy growth. So, it is essential to know some factors that make one cot mattress different from the other.

1. Safety

Since cot mattresses are for kids, safety is the priority. Your little ones require more firmness than you might expect. Thus, ensure that the mattress that you opt for satisfies the firmness standards and thereby prevents SIDS.

Additionally, the materials should be free from VOCs, allergens, and any other component that can be harmful to infants.

2. Mattress Cover

Babies tend to move around when they sleep and may even end up sleeping on their stomachs with their faces smooshed against the mattress. Hence, it is imperative to opt for a breathable fabric cover or any other material with air vents.

Besides allowing easy breathability, such fabrics disperse body heat and moisture and maintain a cool and comfortable temperature.

3. Certification

Always look for brands that back their lofty claims with certifications from Greenguard Gold, CertiPUR-US, etc. and comply with the voluntary Australian Standard AS/NZS 8811.1.

These certifications prove that the mattress meets industry standards of quality and is free from VOCs. It also implies that the product will stand the test of time, thus making it a reliable purchase.

4. Trial Period

Opting for a mattress brand that offers a trial period is always a wise choice. This way, you can check what works best for your baby without the risk of getting stuck with the wrong product. Most Australian brands allow 100-nights of trial to the customers, within which they can return the product and apply for a refund if unsatisfied.

5. Warranty

Another way to confirm the quality of a cot mattress is to check if the brand offers a warranty. By doing so, the brand shows confidence in its product quality and durability.

Now, although a good cot mattress is bound to last long, you must expect the unexpected when you have kids around! So, a warranty for cot mattresses is just as important as it is for high-end gadgets.


And there you have it- the best cot mattresses in the Australian market, along with a brief buyer's guide to help you make the right choice.

Remember that nothing is more important than your baby's health and wellbeing, so never compromise on that aspect. Thus, all of the products listed above are 100% safe and comfortable for infants and toddlers.

But before we sign off, we'd like to reiterate some of our favourites. It is no surprise that the Newton Baby Cot Mattress And Toddler Bed tops the list with its breathable and washable mattress. However, the double-sided Giselle Bedding Pocket Spring and Memory Foam Mattress offers the best value for money.

Let us know which works for you? and we'll be back with more informative guides soon, like our best mattress for kids that might be great for you.
