How to Choose the Right Baby Cot & Mattress for Your Child

When it comes to choosing the right baby cot and mattress, there are many factors to consider: What size do I need? What materials are best? And how firm should it be?

The bulk of the responses are personal preference; nevertheless, for newborns and developing youngsters, certain baby cots and mattresses may be more ideal than others!

In the following blog, we'll look at the many mattress options and describe their primary characteristics and advantages to help you decide which mattress is ideal for your baby's cot or child's bed.


Boori Mattress Styles


We offer a range of mattress styles for Boori families to choose from, such as our 3D Breathable Mattress, Innerspring Mattress, Pocket Spring Mattress and Foam Mattress.

Boori Mattress Styles Explained


Here at Boori Australia, we live and breathe mattresses, but we understand that it may all sound a little Greek to others who aren't in the business. Here we explain the different styles of mattresses previously mentioned.


3D Breathable Innerspring Mattress



The 3D Innerspring mattress is Boori’s dearest cot mattress option. Comprising a supportive steel spring mattress base combined with an extra polyester mesh fibre layer, it is ideal for babies and toddlers seeking optimum comfort and temperature regulation.

Our firm 3D Breathable Innerspring Mattress is available in a Boori Australia cot bed size, which
measures at 132cm x 70cm. Its main feature is its breathable 3D polyester mesh fibre layer, which is porous to allow heat and moisture to dissipate. 

This means your little one will have a comfortable night's sleep, as this technology keeps the mattress cool, which, in turn, helps to maintain and regulate your little one's temperature.

Soft woven fabric outer layers are combined with a Bonnell Spring core to create the perfect level of firmness required for newborns and young babies.

Due to the mesh fibre layer and sturdy steel springs used within the mattress, your
little one's weight will be distributed across the mattress, reducing pressure points that can lead to discomfort. 

Spring mattresses are ideal for back sleepers (like newborn babies!) as their weight is distributed across the mattress.


Innerspring Mattress



The innerspring mattress is one of Boori’s most popular mattresses, offering a supportive innerspring mattress at a more affordable price. It is ideal for those seeking a baby cot mattress that offers great airflow and support. 

Available in a Boori cot bed size that measures 132cm x 70cm, our Innerspring Breathable Mattress features all the same layers as the 3D Breathable Innerspring Mattress but without the additional 3D mesh.

Despite not having the 3D layer, this mattress is still extremely breathable due to its Bonnell Springs, which promotes airflow. 

This reduction of humidity and increased breathability makes this mattress suitable for allergy sufferers, as dust and allergens are less likely to get trapped within the mattress.


Pocket Spring Mattress


The pocket spring mattress differs structurally from Boori’s innerspring mattresses, resulting in some advantages and improved versatility. This mattress is ideal for the whole family, especially growing children. 

Our pocket spring mattresses have a breathable knitted outer layer which provides a soft and gentle layer against your skin. Its woven construction means air can get through the mattress layers, helping control body temperature and promote airflow.

We have several pocket spring mattresses to fit everything from our Boori compact baby cots all the way up to our double beds. They are the most versatile of our mattresses, with a medium firmness suitable for all ages and sleeping positions.

For the perfect balance of comfort and support, our pocket springs are surrounded by a firm layer and then a layer of soft foam. Each pocket spring works independently to react to pressure applied to that area.

Our pocket spring baby cot mattresses are compressed, rolled and packed in a box when they leave our factory. As this takes up less space during travel, we can transport more mattresses and therefore take fewer trips, reducing our carbon footprint. 

They'll also be easier for you to transport home; just make sure you give 24 hours to allow the mattress to expand and flatten before you use it!


Foam Mattress



Our foam mattresses are ideal for families on a budget. Our popular Boori Australia foam mattresses are also available in our oval cot (119cm x 64cm), compact cot (119cm x 65cm) and cot bed (132cm x 70cm) sizes.

Our foam mattresses are made of a nursery-grade sponge with interspersed holes for breathability, in addition to a knitted fabric cover, which helps your child maintain a comfortable temperature.
The knitted cover can be removed for easy cleaning, and as with our pocket spring mattresses, this mattress arrives compressed and rolled for easy storage.


Boori Baby Cot Mattress FAQs


Is my baby cot mattress too hard?


When your baby mattress first arrives, you may be left thinking that your cot mattress is too hard but rest assured that this is likely to be perfect for your new baby cot mattress.

In fact, babies need to sleep on a firm mattress for the first 12 months of life outside the womb, as this helps with their development. As your baby starts to wriggle more and pull themselves up, they will need a firm mattress underneath them to provide the resistance they need to help and support them in doing this.

Think of it like this: as adults, most of us would struggle to get on our feet after sitting on a bean bag. A soft mattress for your new arrival would be the same.

It's important to remember what might feel 'just right' for us adults is likely to be too soft for your baby to sleep on. If your baby mattress doesn't conform to the shape of your little one's head, then the firmness is great.

Ensuring the comfort, safety and quality of your baby is no small task or easy decision. That's why at Boori, we make sure our cots and mattresses comply with the AS/NZS Voluntary Standard (AS/NZS 8811.1:2013).


Why are there mattresses with different heights?


You may notice that the depth of mattresses may differ across our range of mattresses – or whilst generally shopping around. The reasons why can vary depending on the type of bed you are purchasing, the materials used within the mattress itself, or the specific product.

Below we've detailed where and why you might find mattresses with varying heights to help you in your search:

- Our Nova Boori Cot Bed, for example, has a beautiful, curved frame, which requires a mattress to fit its unique design. On our website, you will see a separate mattress listing for this product when browsing our mattresses section, and this will be the only mattress the Nova Cot Bed links to.

- For safety reasons, your top bunk or loft bed mattress should not be thicker than 18cm. This ensures plenty of distance between the mattress's top and the guard rail's top.

    It is important to note that there is a safety standard related to the size of the cot mattress in that a cot must not be more than 20mm from any side or end of the cot when it is centred on the mattress base and no more than 40mm if it is pushed towards one side or end of the mattress base. This is to ensure that there are no gaps in which your baby can get stuck.


    Returning Your Mattress

    We understand that choosing mattresses online can be tricky, so we've created this helpful guide to help you find the perfect mattress for you and your family.

    If you're unsure of what size mattress you need, please contact our friendly team or, for cot bed mattresses, you can look at the label on the slats on the base of the cot bed.

    For hygiene reasons, we cannot accept returns of mattresses if the mattress is not in its original condition and packaging.
