10 Of The Best Cot Mattresses In Australia In 2023

When it comes to getting some shut-eye with a baby in your home, it’s imperative that all the stars align. You’ve got to ensure your awake windows are spot on, your nursery is sleep-friendly, and your cot mattress? Oh that thing better be comfortable!

If you were contemplating just sticking with the mattress that comes with your cot, think again - and then again if you were still considering it! Choosing a quality, comfortable mattress for cots, for your baby is the key to helping them stay fast asleep throughout the night. There are just a few things you need to consider before making your final decision.

What to look for in a cot mattress:

Quality materials:

Like with anything we dress our babies with or lay our babies on, the materials have to be breathable and non-synthetic where applicable. We want to ensure that they stay comfortable in warm and cool conditions and even help to regulate our baby’s temperature when needed.


Some cot mattresses are double-sided, with an infant side and a toddler side. The infant side is somewhat sturdier, to ensure your baby stays safe as they sleep, while the toddler side is slightly more cushioned, as they have no trouble raising their heads as they sleep and can therefore adhere to bedding that is more standardised in terms of comfort.

Standard sizing:

You may have your eyes on a round or oval cot, which is completely fine - beautiful even! But just remember that cot sheets are traditionally sold in one rectangular shape, which may make it a little hard if you find yourself needing sheets that fit - fast!

Approved by Australian standards: 

Australian standards differ from other countries in the world in almost every single category relating to babies. For that reason, it’s imperative that you only buy products - like a cot mattress - that are approved by Australian standards.
