Choosing an organic cot mattress can feel overwhelming. We created this guide to help answer common questions about materials, certifications, firmness, breathability and safer sleep — so you can make an informed choice for your family.
Both mattresses are thoughtfully crafted using premium natural and certified organic materials and are independently tested to meet Australian firmness standards for infant mattresses. The main difference is in the finish, feel and level of practicality vs purity.
Milari Green Baby Mattress:
The Milari Green features our signature pebble-textured sleep surface with a soft, cushioned feel and a breathable water-resistant TENCEL™ blend cover.
Many parents love the practicality of the Green, as its water-resistant surface can help reduce the need for a separate waterproof mattress protector — which often contains materials such as vinyl, polyurethane or synthetic waterproof membranes that may reduce airflow.
The Green is thoughtfully designed for families seeking breathable, everyday practicality while maintaining a premium natural sleep environment.
Best for: families wanting organic comfort with added everyday convenience.
Milari Ultimate Air Mattress:
The Ultimate Air is our purest and most breathable sleep system, crafted using fully certified organic materials and designed without waterproofing.
It features a smooth, refined sleep surface with subtle embroidered detailing and a more natural, structured feel.
By removing waterproofing layers, the Ultimate Air is designed to maximise airflow and breathability for families seeking the most natural sleep environment possible.
Best for: families seeking a fully organic, uncompromised natural sleep surface with maximum breathability.
Which one is right for me?
Choose the Milari Green if you value breathable practicality and a water-resistant sleep surface for everyday family life.
Choose the Ultimate Air if you prefer a fully certified organic sleep environment with no waterproofing and the purest natural material approach.
Both mattresses are dual-sided, breathable and thoughtfully designed to support safer sleep.
What is Organic Cotton?
Organic cotton is a clean, sustainable alternative to conventional cotton. No toxic chemicals are used in processing and manufacturing of organic cotton products. It is produced by farms where no synthetic chemical pesticides, herbicides and fertilizers have been used for at least three years. Instead of using agricultural pesticides, beneficial organisms such as parasites and natural enemies (such as ladybirds) are used for insect management.
Creating a pure, natural environment is an important choice for a growing number of parents. Choosing 100% organic cotton is the first step toward natural living, both for our sensitive babies, as well as our environment. Pesticide and chemically-treated clothing, nappies and bedding block the natural balance of the skin by trapping heat and preventing it from “breathing” which can cause rashes and eczema on sensitive skin. Organic cotton is pure and natural and allows the skin to breathe. Many people consider conventional (non-organic) cotton to be one of the world’s purest fibres, but in actual fact it is one of the world’s most heavily sprayed crops and is believed to cause up to 20,000 deaths and 3 million poisonings every year in developing countries. (Figures from the World Health Organisation- WHO).
Benefit of organics: Organic agriculture protects the health of people and the planet by reducing the overall exposure to toxic chemicals that can end up in the ground, air, water and food supply, and which are associated with health consequences from asthma to cancer. Because organic agriculture doesn’t use toxic chemicals and pesticides, choosing to buy organic products is one way we can help to care for ourselves and our children by leaving behind a clean healthy planet. The benefits of choosing organic cotton are many:- • A healthier planet – no pesticides and hazardous chemicals are used so better for the community and for our precious planet. • Better for farmers and farming communities- farmers and their families are not exposed to the toxic chemicals used in conventional farming which can cause death and poisonings, thus saving lives. • Better for the consumer – as much as 60% of what we put on our skin is absorbed into our bodies thus by using organic cotton we avoid all the unnecessary chemicals which can cause rashes, asthma, allergies etc
FACTS: • Conventional Cotton represents only 2.4% of all cultivated land but uses 24% of all insecticides and 11% of all pesticides used in the world each year. • Chlorine bleach and formaldehyde are used for whitening and finishing in conventional cotton. These are known cancer causing agents. • Conventional cotton uses 84 million pounds of pesticides and 2 billion pounds of synthetic fertilizers every year.
The term organic describes the products of agriculture that use no pesticides or synthetic fertilizers. Organic methods consider the whole eco system and use natural techniques to assist plant growth, repel pests and protect and encourage wildlife habitats. "Working with, not against," nature is the principle behind organic farming. Grown without pesticides and spun without chemicals, organic farmers rely on organic fertilizers, manual crop rotation and integrated pest management. Fields are naturally fertilized, pest-eating insects are used to naturally control crop damage, and weeds are removed with hoes and tractors, as well as by hand. Farms earn the organic label by using soil that has been free of synthetic pesticides for at least three consecutive years.
At Milari Organics, we value certified organic materials because we believe what surrounds your little one during sleep should be thoughtfully chosen, beautifully made and transparently sourced.
Because safer sleep starts with what’s inside.
“Organic Certification” means that a product has been farmed in accordance with the strict and uniform requirements that have been verified by an independent body. Some of these bodies include Control Union (formerly known as SKAL), ECOCERT, OCIA- Organic Crop Improvement Association and IMO. Certification includes inspections in farm fields as well as the production process facilities, recording of detailed data and periodic testing of soils and water in order to guarantee that producers and handlers are fulfilling the necessary requirements.
Fair trade is a trading partnership based on dialogue, transparency and respect that seeks greater equity in international trade. It contributes to sustainable development by offering better trading conditions to, and securing the rights of, marginalized producers and workers. From the International Federation for Alternative Trade. (IFAT)
Many families choose organic products because organic farming practices are designed to work more thoughtfully with nature.
Compared with many conventional farming systems, organic agriculture generally avoids synthetic pesticides and fertilisers, while placing greater emphasis on soil health, biodiversity and more responsible land management.
By reducing reliance on many synthetic chemical inputs, organic farming can help support healthier ecosystems, cleaner waterways and more sustainable growing practices.
At Milari Organics, we believe thoughtful choices — for our children and our planet — matter.
Because caring for little ones also means caring for the world they grow up in.
Nanosphere technology is one of the key technologies of the 21st century. Bound to the fabric it offers non-stick cleaning effect often observed in some plants like a lotus flower.
Similarly, the nanosphere particles are bound to the fabric and prevent moisture and dirt from penetrating the surface. Unlike many conventional waterproof sleep products that rely on plastic coatings, vinyl or synthetic waterproof membranes, the Milari Green is thoughtfully designed to balance practicality with breathability, softness and comfort.
For many families, this means added everyday protection without compromising the natural feel of a thoughtfully designed sleep environment.
Because safer sleep should feel practical, too.
Many conventional waterproof mattress protectors rely on plastic-based waterproof membranes that they are made with toxic chemicals and plastics vinyl, polyurethane and formaldehyde. These coatings reduce airflow through the sleep surface which can lead to overheating and can contribute to a wide range of health issues, including asthma, eczema, attention deficit and many others
At Milari Organics, we prioritise breathability, airflow and thoughtfully selected materials — because temperature regulation and comfort matter during sleep.
For this reason, we generally do not recommend adding traditional waterproof protectors over breathable natural sleep surfaces, as they may reduce airflow and change the feel of the mattress.
Instead, the Milari Green Mattress features a breathable water-resistant sleep surface designed to offer added everyday practicality while maintaining airflow and comfort.
Families seeking a fully breathable, non-waterproof sleep surface may prefer our Milari Ultimate Air Mattress.
When choosing a cot mattress, we believe parents should look beyond marketing language and consider the materials, firmness, breathability and independent testing behind the product.
Things worth considering include:
• Appropriate firmness for infants — infant mattresses should be firm and supportive. Avoid mattresses described as soft or medium-feel for newborn sleep.
• Independent testing and transparency — look for brands that openly share testing, certifications and material information rather than relying solely on brand claims.
• Thoughtfully selected materials — Choose natural and certified organic materials such as latex, coconut coir, wool and organic cotton for breathability and transparency around sourcing.
• Breathability and airflow — breathable construction and airflow may help support a more comfortable sleep environment.
• What’s inside the mattress — Avoid polyurethane foams, memory foams, synthetic waterproof membranes, the petroleum and chlorine-based Vinyl or PVC used for waterproofing (a known carcinogen), chemical flame retardants or unnecessary adhesives
At Milari Organics, our mattresses are independently tested to meet the AS/NZS 8811.1 firmness standard for infant mattresses and thoughtfully crafted using premium natural and certified organic materials including coconut coir, GOLS-certified latex, Australian wool and GOTS-certified organic cotton.
Our dual-sided sleep systems are designed to support growing babies — combining firm infant support, breathability and long-term comfort as your child grows.
Because safer sleep starts with what’s inside.
