The 5 Best Organic Cot Mattresses In Australia 2021 Summarized

Best Organic Cot mattresses in Australia

Planning for a new baby? Or is it already on the way? You should know that babies need about 16 hours of sleep per day at their early stages. 

Cots that are small beds for babies and little children feature mattresses that may contain high levels of toxic chemicals as a result of the kind of materials they are made from. These toxic chemicals can cause Sudden Infant Death Syndrome (SIDS) or interfere with normal growth in children. A healthy cot mattress is the first step towards ensuring great uninterrupted sleep for your baby.

An organic cot mattress is a model that features materials made from plants, devoid of any chemical additives. Obtaining a cot mattress that is 100% organic can be difficult to achieve as most waterproofing materials and fire retardants are chemically treated. Despite this, Australian cot mattresses that are certified by GOTS (Global Organic Textile Standard) contain very low toxic chemicals and are considered safe for your baby.

Keys Considerations When Choosing The Best Organic Cot In Australia In 2021

Construction and Material: That a mattress is labeled ‘organic’ does not mean it is totally organic. Most cot mattresses need a waterproof cover to prevent damage to it.  An additional waterproof cover may sound like a good idea until you realize that the material used in its design is plastic that contains PVC (polyvinyl chloride). PVC is a toxic chemical that is capable of causing liver cancer and other health problems. An organic cot mattress should be made with non-toxic materials which may include high-density foam that is dust-mite free and hypoallergenic.

Ensure that your organic cot mattress is certified by the right authorities. It must have a 100% organic cotton cover as it tends to maintain direct contact with the skin of your baby.

Firmness: A cot mattress should be firmer than most traditional beds. This is because a softer surface can be too conforming, making it difficult for babies to change position with ease and then suffocate. 

Temperature Regulation: Body heat increases emissions of toxic chemicals used in cots and cribs. Organic cot mattresses, however, feature cotton covers that are breathable and wicks away moisture, as well as expels heat.

Size: Most cots come with a mattress. In a situation whereby it has no mattress or you intend to buy a replacement, you can purchase one that will fit into the cot using its correct measurement. The Australian Standard for a cot mattress size AS/NZS 2172:2013 specifies that the mattress should be less than 

  • 20mm from any cot side when placed in the center of the cot
  • 40mm from any cot size when placed at an end

This specification is because large gaps between the mattress and the cot can be dangerous for your baby. Again the mattress should not be too large as to not fit snugly in the cot. A cot and its mattress size are often indicated at the base of the frame to guide buyers. The size can also be custom made if that is what you desire.

Price: The price of a cot mattress is based on the mattress materials and quality. Organic cot mattresses are rather expensive, but the absence of toxic materials makes them worth the price.

Frequently Asked Questions (FAQs)

What mattress is best for a cot bed?

A cot mattress should be quite responsive that it does not lose its shape when a baby is laid on it. It should be non-toxic and organic, whether it is made of foam, latex, pocket springs, or other materials. An organic cot mattress could be the best way to give your child a healthy sleep. They are made of organic cotton which is locally grown without the use of chemicals, as well as natural plant-based fibers.

How do I choose a baby mattress?

Babies spend a long time sleeping. While laying down directly on these mattresses, they could be absorbing and breathing in the emissions from its components. It is important to get good quality mattresses that are certified to be free of toxic chemical emissions for cots. An organic mattress is the best option here, as it ensures that the baby’s health is protected. The mattress should also be thick and firm to carry the baby’s weight.

How thick should a cot mattress be? 

A baby’s mattress should be such that the distance from the top surface of the mattress to the top of the dropside is far from the baby’s reach. This is so that babies do not roll over or climb out on their own at any point in time.  

How does a second-hand mattress cause cot death?

A baby’s mattress needs to be firm. Mattresses get soft from usage as the fortifications around the edges become weak too.  Used mattresses are prone to having harmful microbes and bacteria trapped within them, which could be harmful to a baby and increase the risk of cot death. When you plan on reusing an old mattress, it is good to ensure that it is in good hygienic condition. Organic cot mattresses can be reused if they are still firm and clean.

Should babies sleep on a hard mattress?

A very soft mattress increases the risk of Sudden Infant Death Syndrome (SIDS), especially if your baby lies face down. The Australian/New Zealand standard for mattress firmness ensures that producers of baby mattresses do not go below a certain range of firmness.

Final Thoughts

Every baby needs sleep for growth and development. The sleeping surface can be a source of harm to them. This is why it is necessary that one asserts the baby’s safety by providing him/her with an organic cot mattress. This lowers the risk of certain childhood ailments and even death while improving sleep quality for better blood circulation.
