A quality sleeping surface is so important for good sleep, and it’s doubly true for babies, whose tiny bodies are still developing and need all the support they can get whilst ensuring safe sleep.
You’ve already picked out a beautiful cot, and now it’s time to think about the mattress for your baby. With young babies and toddlers spending so much of their time in slumberland, naturally you want to make sure you make the right choice in terms of safety, comfort and support for your newest family member.
With sudden unexpected death in infancy (SUDI) a very real risk, your first concern will be whether or not the mattress is safe. Red Nose, Australia’s leading authority on safe sleep advice, stipulates that a safe sleeping surface for babies should be firm, clean, flat, and the right size. In addition to this, you want your baby or toddler’s body to be properly supported as well as being comfortable enough to sleep well, so there’s certainly a lot to think about when making your decision.
As cot sizes are not standardised and with some cot brands even having designed their own unique sizing, it can be a hassle just to make sure the mattress you choose fits your cot correctly. For this reason, we have included the dimensions of each of our reviewed cot mattresses to make this as easy as possible.
Read on to see our list of the best cot mattresses for babies and toddlers currently sold in Australia.

We would consider this mattress to be medium in firmness for those who prefer a slightly softer, yet still safe, sleeping surface.
The mattress’s core is made of independent tempered innersprings, with alternating layers of breathable cotton, egg shaped foam to gently massage the body, and a polyester padding for comfort. The whole package is then encased in an outer layer made of a luxurious aloe vera knitted fabric. Not only is this highly breathable, it’s also naturally antibacterial, resistant to dust mites and super soft to the touch.
With baby safe rounded corners, all edges are reinforced for excellent durability and to reduce wear and tear over time. We love that you can flip it over for mattress rotation as it can be used on either side - an underrated and handy feature not all cot mattresses possess. With the cover unable to be removed, we recommend using this mattress with a breathable mattress protector.
Types of cot mattresses
Here we talk briefly about the common types of cot mattresses, so you can better navigate the different options and choose wisely.
- Innerspring. Typically offering the most support, innerspring mattresses are made of coiled springs that are covered in a layer of foam, and is probably the type of mattress you have for yourself. The springs independently compress under body weight and then spring back again when the weight is lifted. Resistant to sagging, innerspring mattresses usually last the distance however are often quite heavy and more expensive than other types of mattresses.
- Latex. Latex is a natural material that is both breathable and hypoallergenic and will contour slightly under the weight of your baby. They are long lasting, and although latex does have a natural elasticity, it will remain firm enough to provide a safe sleeping surface and will also hold its shape well.
- Foam. The most cost effective type of mattress, foam mattresses are lightweight and easy to transport. They are, however, prone to sagging over time and don’t naturally carry the same hypoallergenic properties as latex mattresses, though some are treated to do so.
- Combination. Many cot mattresses are now constructed of a combination of the above materials, delivering a mattress that utilises the best features of each type. Not surprisingly, combination mattresses often carry a hefty price tag, but it could be worth the investment for the perfect mattress.
How to choose a cot mattress for baby
Here are some of the factors to consider when choosing a cot mattress for baby and kids mattresses.
Size. As mentioned previously, there is no standardised sizing system for cots or their mattresses in Australia. For safety reasons, you’ll want a mattress that fits snugly inside your cot with no gaps where baby could get stuck (no more than two finger widths is a good rule), so it’s important you choose a mattress that is the appropriate size. Remember to also consider the height of the mattress - very high mattresses mean its surface is closer to the top of the cot railings and whilst it won’t make any difference for a newborn, older babies and toddlers might be able to use this extra height to climb over the edge of the cot.
Firmness. You can be forgiven for thinking that a soft, plush mattress surface is the best and most comfortable choice for your baby, but did you know that cot mattresses with soft surfaces actually increase the risk of sudden unexpected death in infancy (SUDI) and related sleeping accidents? If your baby rolls over onto his face when asleep, a soft surface could potentially envelope his airways, whereas a firm surface won’t have the same “give” and will maintain its flatness, allowing a passage for air. The right mattress firmness will also support baby’s growing skeleton for a healthy development.
Materials. Whilst one is not necessarily better than others, you may have a preference for what materials the mattress is constructed of. Cotton is a popular and natural, breathable material which will absorb moisture. For babies at risk of or with allergies, you might consider mattresses made hypoallergenic materials, commonly latex or memory foam. You might prefer your baby sleeps on natural or organic fibres rather than synthetic, or materials with moisturising or cooling properties such as aloe vera.
