When it comes to setting up your baby’s sleeping space, the cot mattress is an important product to get right. To help little ones get the sleep their bodies need, your baby mattress should be the perfect mix of comfort and safety.

Available in various sizes to fit all types of cots, cot mattresses in Australia vary in styles from traditional inner-spring options to foam and contemporary mesh designs that are completely washable.

With the safe amount of firmness and a gentle cover, the right sleep surface goes a long way to getting baby’s sleep routines under control – and help the rest of the family catch sweet dreams and overdue zees.

What to consider when buying a mattress

Firmness: Red Nose explains that baby mattresses should be firm and compliant with the Australian voluntary standard.

Ease of cleaning: Look for materials that are easily cleanable, and importantly, that dries fast enough to be ready for the next nap.

Size: According to Product Safety Australia, when a mattress is centred it should not be more than 20mm from any cot side or end.

What size mattress do I need for my cot?

While standard cot mattresses in Australia are approximately 130 x 70cm, the size you need depends on your particular brand of cot. To establish exactly what size you need for your baby’s special sleeping space, check the manufacturer guidelines before you buy.

Why are baby mattresses firm?

Soft sleeping surfaces are considered to be unsafe for babies, especially when tummy sleeping occurs.  To reduce the risk of accidents, firm mattresses are suggested to give babies a stable surface and prevent them from sinking into the bedding. A firm mattress also provides good resistance when babies push up or stand in the cot (when they should be sleeping!)

Is it safe to use a second-hand baby mattress?

The latest information provided by Red Nose states that “there is no detectable increase in risk using one second hand so long as it’s clean, not torn and well-fitting.” Of course, if you are in any doubt as to the cleanliness and condition of a mattress, err on the side of caution and look for another one.
