  • 11-layer construction for superb support and durability;
  • aloe vera knitted fabric for a fresher feel and improved breathability;
  • egg-shaped foam layer to provide gentle massage;
  • can be used on both sizes for increased convenience and a longer lifespan;
  • medium-firm feel to achieve a balanced combination of support and comfort.

The first item that deserves to be among the best cot mattresses in Australia is this multi-layered model by Giselle Bedding. Everything about this crib mattress screams comfort and quality. First of all, it is quite firm and can guarantee proper support for your baby. Secondly, the construction of this little mattress is on a whole new level.

Now, the Giselle Bedding cot mattress is 13 cm thick and uses multiple layers to achieve a unique feel (and, of course, to offer an impressive set of features). The core of the mattress is made of independent pocket springs that are meant to deliver reliable support. There are also extra layers of foam, cotton, non-woven fabric, and fiber padding. The foam has an egg-crate design for gentle massage and increased comfort. Plus, both sides of this cod mattress are equally comfortable and can be used interchangeably. It will allow you to keep the mattress fresh. And since the pressure will not be applied to only one side of the mattress, it will remain supportive longer.

  • foam layer for targeted support and extra comfort;
  • cotton cover for increased breathability;
  • innerspring core system for reliability and proper support;
  • side ventilation to allow for good airflow and to maintain a temperature-neutral sleeping environment;
  • soft and smooth cover, hypoallergenic and gentle on skin.

Looking for a top-quality cot mattress in Australia but don’t want to spend a fortune on it? Well, look no more, as this crib mattress by Adairs is here to save the day. Using premium materials and boasting of top-notch manufacturing quality, the Adairs offers superb comfort for an attractive price. This mattress uses tempered steel springs that serve to deliver reliable support and promise durability in use. Additionally, there is a layer of high-density foam, which is also quite durable.

You might also appreciate the fact that the Adairs mattress has special side ventilation channels. They can help create a pleasantly cool sleeping environment for your baby. Combine that with a cotton cover, and you get an impressively breathable cot mattress. Such a smart construction might also help you keep the mattress fresh and clean. And since the ventilation system prevents moisture retention, you don’t have to worry about mold, dust mites, or other scary allergens.

  • multiple sizes available to satisfy a wide range of shoppers;
  • the company offers customizable size options as well, which means there’s an option for any crib;
  • cotton cover, soft and smooth to the touch, won’t irritate the skin;
  • innerspring system for sturdy, reliable support;
  • customization is free, which means no strain on your budget.

If you want more size options or your baby’s crib has unusual dimensions, it might be hard for you to find a suitable cot mattress in Australia. Don’t worry though: the Babyworth has got you covered. The company offers 5 size variations that would work for different types of cribs. And here’s the best part: you can also order a custom cot mattress based on your specific requirements and needed dimensions. How cool is that? You can get pretty much any mattress size suitable for any crib!

And the list of benefits the Babyworth offers doesn’t end there. For instance, the cover is made of organic cotton. It is hypoallergenic and safe for your baby’s skin. Plus, it’s also super breathable and will keep your little one sweat-free (and the sleeping environment fresh). The core of the mattress is the tempered steel innerspring system with steel edge banding. Such a construction makes this mattress extra sturdy and reliable in use. It will deliver proper support for your baby without making noise when there’s movement on top.

Types of Cot Mattresses and Their Benefits

When browsing through Australia’s best cot mattresses, you can stumble across different options. And to pick the most suitable one for your baby, you need to understand the difference between them. Here are the most common ones:

  • Foam. Just like the adult version of the top-rated memory foam mattresses in Australia, foam cot mattresses are supportive, easy to clean, and affordable. They are also usually lightweight and easy to flip, in case you want to use both sides. However, you need to be careful with the foam type, as low-density models can lose their supportive properties rather fast.
  • Innerspring or pocket spring. Standard innerspring mattresses use open coils and usually some type of padding (foam or fibers). Pocket spring mattresses feature individually wrapped coils and tend to be more comfortable and supportive. Bear in mind that spring cot mattresses are usually more expensive than foam ones.
  • Natural fiber. There are options filled with such eco-friendly materials as wool, bamboo fibers, coconut coir, organic latex, etc. They are chemical-free and tend to hold their shape quite well with time. However, such mattresses are among the most expensive ones on the market.

How to Choose the Best Cot Mattress for Your Baby: Buyer’s Guide

It might seem difficult to choose among Australia’s best cot mattresses.

Don’t worry though:

Once you understand what you are looking for exactly, the list of options will become smaller.

And to do that, consider the following factors when shopping:

  • Type. The mattress filling is probably the most important component as it will determine the feel and the durability of the product. You are already familiar with the main types and their pros and cons, so you can decide which one would work for you before finalizing your purchase.
  • Firmness. For babies between 0 and 12 months, experts recommend choosing firm mattresses (1). A soft cot mattress would simply be unsafe for your little one.
  • Safety. It doesn’t only end with a proper firmness level. A safe cot mattress is the one that is free of harmful chemicals and potential allergens. Look for safety certifications (such as Oeko-Tex, GreenGuard, Global Organic Textile Standard (GOTS), etc.).
  • Trial and returns. Not all companies offer a sleep trial, but at least you should get a certain return window. This aspect is important as it will protect you as a customer in case the item arrives damaged or with defects. Plus, you will get a chance to return the mattress in case it doesn’t work for you and your baby.
  • Versatility. Some cot mattresses are flippable, which means you can use both sides. Now, many parents prefer this type as it allows them to keep the mattress cleaner. Flipping the mattress may also increase its lifespan (as you are going to apply pressure to both sides from time to time instead of only one of them). 
  • Cover. The cover fabric is the closest to your little one’s body, so it must be safe and hypoallergenic. Cotton or bamboo work great in this case (plus they are very breathable and allow for proper air circulation during sleep). Some parents also choose mattresses with waterproof covers for easier maintenance. However, keep in mind that a waterproof mattress can’t be 100% natural (as the water-resistant layer is typically made of PVC).
  • Shipping. With a new baby, you probably have thousands of things on your to-do list. So, it’s better to order from a company that offers the most convenient delivery conditions. There are many stores that sell mattresses in a box and won’t require you to carry a bulky mattress into your baby’s room. Instead, the mattress can arrive compressed in a box for better portability. 
  • Reviews. This one might seem obvious, but many shoppers forget to read cot mattress reviews before ordering one. And that can be a mistake, as the reviews can help you learn about the product’s potential downsides.
  • Thickness. A good cot mattress should be at least 10 cm thick (and no more than 15 cm tall) (2). Because your baby’s weight will be concentrated on a rather small area, an overly thin mattress will not be able to offer proper support and might allow for unwanted sagging in that area. The proper thickness will ensure good support. Plus, thicker mattresses tend to develop sags later.
  • Size. Most cot mattresses have standard dimensions, but you can still find size variations. There are also companies that make custom mattresses, in case your baby’s cot is a bit different in size or shape.

How to Choose the Best Cot Mattress for Your Baby: Buyer’s Guide


A quick note: while you are choosing a good mattress for your baby, don’t forget about yourself. Spinal health is very important, so to take care of your back, consider getting yourself a new mattress too (for instance, there are plenty of great mattresses for bad backs in Australia).



How thick should a cot mattress be?

A cot mattress should be at least 10 cm thick.

Should babies sleep on firm or soft mattresses?

Firm mattresses are proven safer for babies.

Why do babies need firm beds?

A firm cot mattress would provide decent support for the baby’s skeleton and can prevent suffocation.

What is the best type of cot mattress?

The best type of cot mattress is a firm and a quality one. As for the materials used, it depends on your personal preferences. Some parents choose foam because such cot mattresses are affordable and easy to care for. Others prefer coils for their breathability and resilient support. And some buy cot mattresses that use natural fiber filling because they want their babies to sleep in 100% safe beds.

Can a mattress be too firm for a baby?

Generally, no. Even if your baby’s mattress feels too stiff, it’s supposed to be that way.

Wrapping Up

Naturally, you want only the best for your baby.

Including the cot mattress.

The good news is, you already know what makes a great cot mattress. So, consider the material types when shopping and don’t forget to check the company’s return policy. Remember that a good cot mattress has to be firm and safe for your little one. And don’t neglect reading other shoppers’ reviews as they can help you get a full picture of the product you are considering.

Not sure what to pick? In this case, I have a suggestion. The cot mattress that managed to impress me the most was the Giselle Bedding. Using a multi-layered construction, it is very supportive and reliable in use. This mattress is also flippable, so you can use both sides. And you might also appreciate the fact that it’s designed to offer gentle massage to your baby, which might even help them sleep more comfortably.
