A standard single mattress is often a practical first “big kid” bed in Australia. It gives one child their own comfortable sleep space without taking up too much floor room, and it can suit many children for years when the length, bed frame and support feel are right.
The most important step is to match the mattress to your child’s room, current height and likely growth. Explore the Eco Kids mattress collection, then check the exact dimensions and depth of the model you are considering against the bed frame before ordering.
Standard single mattress size in Australia
In Australia, a standard single is commonly around 92 cm wide by 188 cm long. Always check the product specification before buying.
Here is a simple kids mattress size guide Australia families can use when planning a room:
| Mattress size | Typical Australian dimensions | A practical fit for |
|---|---|---|
| Single | 92 cm × 188 cm | Children, compact bedrooms, bunk beds and guest rooms |
| Long single | 92 cm × 203 cm | Taller children who need more leg room without extra width |
| King single | 107 cm × 203 cm | Growing children and teenagers who want more room to stretch out |
| Double | About 137–138 cm × 188 cm | Children or teenagers who need more width and have room for a larger bed |
Measure the inside of the bed frame, not just the available floor space. Also check mattress depth if you are buying fitted sheets, using a trundle or choosing a bunk bed with a safety rail; Eco Kids double-mattress depth varies by model.
Kids mattress age guide: when does a single make sense?
There is no fixed age for a single mattress. Consider your child’s current bed, bedroom space and growth.
- First big-kid bed: A single is a common next step beyond a cot or toddler bed.
- Primary-school years: A standard single can be a space-efficient choice.
- Taller children and teenagers: Consider a long single or king single for extra length, or a double when extra width is the priority.
Think ahead, but a well-fitting single can be right for a compact room, bunk or trundle.
Single, long single, king single or double?
The best kids mattress Australia choice balances room layout and growing space. A long single adds 15 cm of length without changing the width.
A king single adds length and width for older children, teenagers or active sleepers. It also needs a larger frame, more bedroom space and king-single bedding.
A double mattress is wider than a king single but shorter. It can work well for a child or teenager who wants more room to spread out, provided the bedroom comfortably accommodates the larger footprint. Eco Kids lists double sizes for selected models, so check the individual product page for the precise width, length and depth.
Before you decide, mark the bed’s footprint on the floor with masking tape. Leave enough room for the door to open, everyday movement, storage and any furniture your child needs to use independently.
What to look for in a kids mattress
The best kids mattress is not only about size. Check comfort, bed-frame fit, materials and care information.
Support and comfort
Children need a mattress that feels comfortably supportive rather than overly soft or hard. If possible, let your child lie on the mattress in their usual sleep position, or use the home trial to assess whether they settle comfortably over several nights.
Mattress height for bunks and trundles
Always follow the bed-frame manufacturer’s mattress-height guidance. This is especially important for bunk beds, where the mattress must sit low enough for the guard rail to provide the required protection.
Materials and certifications
Look for clear material information and relevant certification details. Eco Kids states that its mattresses use 100% vegan, eco-conscious materials, with foams that are GECA or Global GreenTag certified and approved by the National Asthma Council’s Sensitive Choice program.
Trial and everyday care
A home trial can be useful when buying online because your child can experience the mattress with their usual pillow, bedding and bedtime routine. Check the return terms, care information and the recommended bed base before buying.
Eco Kids mattress options for growing families
Eco Kids offers the Eco Kids Mattress, Eco Kids Pillow Top Mattress and Eco Kids Bunk Mattress. The collection describes the range as Australian made, with a Chiro Flex ES spring system and eco-conscious materials.
The collection also offers a 150-night risk-free trial, with a full refund if you are unhappy during that period. As sizes, mattress depth and model-specific features are not listed on the collection page, confirm the individual product details and bed-frame compatibility before you place an order.
Browse Eco Kids mattresses to compare the available options. For bunk or trundle use, confirm the mattress height first, then choose the model that best suits your child’s comfort and your bed-frame requirements.
Quick buying checklist for parents
Before buying a single mattress for kids Australia families should confirm:

- Whether a single, long single, king single or double is the better fit for the room and growth needs.
- The materials, comfort construction and certifications you value.
- The trial, return, warranty and care terms.
