Choosing the right cot mattress involves more than simply comparing prices. Factors such as firmness, breathability, materials, and cot compatibility can all play an important role in your baby’s comfort and safety.
Below, we’ve answered some of the most common questions to help you choose the best cot mattress for your family.
Why buy a quality cot mattress?
Your baby will spend many hours sleeping during their first few years of life, making a quality cot mattress an important investment. A good cot mattress should provide a firm and supportive sleeping surface while also promoting breathability, hygiene, and healthy spinal development.
Many modern cot mattresses also use non-toxic materials, washable covers, and innovative designs that make them easier to clean and maintain. These features can provide added peace of mind for parents while helping to create a comfortable sleep environment for their baby.
What makes a good cot mattress?
A good cot mattress should provide a firm, flat sleeping surface that supports your baby’s growing spine. It should also be breathable, well ventilated, and fit snugly inside the cot without leaving excessive gaps around the edges.
Many premium cot mattresses also include practical features such as removable covers, washable components, and non-toxic materials. These features help improve hygiene and make it easier to keep the mattress clean throughout the inevitable spills and accidents of everyday life.
When should my baby move to a cot?
The right time to transition from a bassinet to a cot will vary depending on your baby’s size, development, and your family’s individual circumstances. Many parents make the move once their baby begins to outgrow the bassinet or starts rolling over and becoming more mobile.
As a general guide:
- 0–6 months: Bassinet mattress
- 6 months–2 years: Cot mattress
- 2–5 years: Single, king single, or double mattress
Every child develops differently, so these ages should only be used as a general guide.
Natural latex vs foam cot mattresses
Natural latex and foam are two of the most common materials used in modern cot mattresses. Both can provide excellent support, although they offer slightly different characteristics.
Natural latex is known for its durability, responsiveness, and use of natural materials, while foam cot mattresses are often lighter in weight and generally more affordable.
Some mattresses also use innovative polymer or mesh constructions that maximise airflow and ventilation. Ultimately, the overall design and build quality of the mattress are more important than the material alone.
Are breathable cot mattresses worth it?
Breathability has become one of the biggest innovations in the cot mattress market over recent years. Many modern cot mattresses now incorporate ventilated covers, airflow channels, breathable foams, or open-core designs that encourage better air circulation.
Improved airflow may help with temperature regulation and creates a fresher sleeping environment for your baby. While different products achieve this in different ways, breathability is certainly a feature worth considering when comparing cot mattresses.
How firm should a cot mattress be?
A cot mattress should provide a firm and supportive sleeping surface. This helps support your baby’s growing spine while creating a stable sleep surface during the important early stages of development.
Soft or overly cushioned mattresses are generally not recommended for infants. Instead, look for a cot mattress that has been designed specifically for babies and complies with the Australian infant sleep surface firmness standard (AS/NZS 8811.1:2013). All of the cot mattresses featured in this guide meet this standard.
It’s worth remembering that a firm cot mattress does not have to feel uncomfortable. Many modern cot mattresses combine a supportive feel with breathable materials and carefully designed comfort layers, helping to create a sleep surface that is both safe and comfortable for your baby.
Cot mattress sizes
Before purchasing a cot mattress, it’s important to ensure it is compatible with your cot. A mattress should fit snugly within the cot, without leaving excessive gaps around the edges.
The most common cot mattress size in Australia is 130cm × 69cm, although some cots require different dimensions. Many manufacturers also offer additional sizes to suit larger, smaller, or uniquely shaped cots.
If you’re unsure which size you need, we recommend measuring your cot or checking the manufacturer’s specifications before purchasing. You can also refer to our guide to Australian mattress sizes, which includes a discussion on standard cot mattress dimensions.
How long does a cot mattress last?
A good quality cot mattress should comfortably last throughout your child’s infant and toddler years when used and cared for correctly. Durability will vary depending on the materials, construction, and how frequently the mattress is used.
Washable and well-maintained mattresses may also be suitable for future children, provided they remain in excellent condition and continue to fit the cot safely. Always follow the manufacturer’s care instructions to maximise the life of your mattress.
Cot beds vs cot mattresses
The terms “cot bed” and “cot mattress” are often used interchangeably, but they actually refer to two different products. A cot bed is the frame or structure that your baby sleeps in, while the cot mattress is the sleeping surface that sits inside it.
When purchasing a cot mattress, it’s important to ensure it is compatible with your cot bed. The mattress should fit snugly within the frame, without leaving excessive gaps around the edges, to help provide a safe and supportive sleeping environment.
Most household cots sold in Australia are designed to comply with AS/NZS 2172:2013 (Cots for household use – Safety requirements), which forms one of the recognised standards under Australia’s mandatory product safety requirements.
All of the products featured in this guide relate to the cot mattress only. If you’re also looking for a new cot bed, be sure to check out our list of cot beds.
Which cot mattress is right for you?
The best cot mattress for your family will depend on your budget, preferred materials, and the features that matter most to you.
If you’re looking for the best all-round performer, the Airnest Cot Mattress remains our top recommendation thanks to its exceptional breathability, innovative design, and outstanding hygiene features. Parents seeking a premium natural mattress should consider the Peace Lily Cot Mattress, while the Ecosa Cot Mattress offers the added flexibility of adjustable firmness as your child grows.
For families wanting a premium Australian-made cot mattress, the Eco Kids Latex Luxe Cot Mattress combines natural latex comfort layers with a supportive innerspring design and impressive safety credentials. Meanwhile, the Babyrest DuoCore™ Bamboo Cot Mattress offers excellent value with its dual-sided infant and toddler design, lightweight construction, and wide range of available sizes.
Regardless of which product you choose, all of the cot mattresses featured in this guide performed well during our testing and are products we would happily recommend to Australian families.
