Numu is a revolutionary baby mattress made of a single mesh layer.

It is safer, friendlier, and contributes to a better sleep for both bub and mum.

Our unique design eliminates dust mites and increases airflow, which prevents accumulation of CO2 and overheating.

Sensitive Choice, with their strict health standards, chose Numu as a partner mattress making it the best and safest mattres. . . Show More >


Free flow of air, which lets your baby breathe, whatever their position.

Prevents accumulation of CO2 , which is one of the most important factors when it comes to your baby's ability to breathe the oxygen levels necessary for their well-being.

Prevents reflux asphyxia , when regurgitated food and mucus penetrate the mattress surface, exiting through the screen, preventing the baby from taking a secondary aspiration of them.

Makes breathing easier in case of respiratory illness.

Prevents overheating , helping the baby not to sweat and to sleep at a temperature considered healthy (between 18 and 22 degrees).

  Helps to prevent the accumulation and survival of mites helping to keep your baby's sleeping surface clean, ideal for babies suffering from asthma and allergic rhinitis .

Antiallergic , good for babies with sensitive skin or suffering from allergic dermatitis.

Easy to clean and quick drying , through the Air Nettress screen..

- The mattress includes a Confort Layer. This extra layer helps to increase your baby's comfort and does not take away any of the characteristics of the Numu mattress.


The Mattress is made of an aluminum structure and a special, very thin polyester net.

All materials used are recycled for a smaller ecological footprint.

A Breathable Baby Mattress

If your baby turns over on their stomach, they'll have the space to breathe. Research has found the Numu mattress to help remove co2 emissions and reduce other known risk factors - read here our SIDS safe blog.

Our unique design means there isn’t anywhere for dust mites to live or for dust to accumulate on the mattress. This is especially handy for babies who are prone to allergies, asthma, and eczema. The Numu is even backed by the National Asthma Council of Australia!

The single mesh layer stays cool, even during hot Australian summers. Your baby will sleep sweat-free through the balmy nights, which means more sleep for you too!
