Choosing the Right Kids Mattress
Buying for a child is mostly a sizing and durability decision, with a sensible support level on top. It doesn't need to be complicated. Here's the honest version of what matters and what doesn't.
Size: single or king single
This is the main decision, and it's about how long you want the mattress to last as they grow:
- Single (about 92 × 188 cm): the standard choice for younger children and a toddler's first big-kid bed. Also the size most bunk beds take.
- King single (about 107 × 203 cm): noticeably longer and a little wider — better for taller children and teenagers, and it buys more years before they outgrow it.
If you're buying for a child who's growing fast, king single is often the more economical choice over time even though it costs a little more up front.
Support: medium-firm is the sensible default
For a growing child, a medium-firm feel is the usual recommendation — supportive enough to keep a young body well-supported, without being uncomfortably hard. Very soft mattresses generally aren't ideal for children, and very firm ones aren't necessary. If you want to look specifically at that feel, the medium firm range covers it across constructions; many kids mattresses at this size and price are pocket spring or value innerspring, which suit children well.
Durability: kids are hard on beds
Children jump, bounce and treat a bed as furniture and trampoline. A kids mattress earns its keep by holding up to that, which is why durability matters more here than premium comfort features they won't notice. The good news is a sensible, well-made kids mattress doesn't need to be expensive — this range starts at $99 for a single for exactly that reason.
Toddler's first big bed
Moving a toddler out of a cot usually means a single mattress, often low to the floor or in a low frame so it's easy and safe to climb in and out. The priorities are simple: the right size, supportive medium-firm feel, and a durable build — the same things that matter for older kids, just at the start of the journey.
When to replace a kids mattress
The honest, most common reason is simply that they've outgrown the size — feet near the end, or cramped on a single that suited them three years ago. Beyond that, replace it if it's visibly sagging or your child is consistently uncomfortable on it. There's no need to replace on a fixed schedule if it still fits and supports them well.

Why buy your kids mattress from A2Z
The A2Z Furniture is a family-run Australian business established in 2013.

Because we import directly and sell from our own Brisbane warehouse, a kids mattress is genuinely affordable rather than marked up and discounted back. Stock is held with pick-up seven days a week, plus Free Local Delivery on eligible orders from Rocklea.

Kids Mattress FAQs
What type of mattress is best for kids?
A medium-firm feel is the usual sensible recommendation for a growing child — supportive without being hard. Very soft isn't ideal and very firm isn't necessary. Pocket spring and value innerspring builds at this size suit children well; see the medium firm range for that feel.
What size mattress should I get for my child?
A single (about 92 × 188 cm) suits younger children, toddler first beds and bunks. A king single (about 107 × 203 cm) is longer and better for taller kids and teens, and lasts more years before they outgrow it.
Is a single mattress good for a toddler's first bed?
Yes — a single is the standard step up from a cot, usually low to the floor or in a low frame so it's easy to get in and out of. Look for the right size, a supportive medium-firm feel, and a durable build.
How often should I replace my child's mattress?
The most common reason is simply that they've outgrown the size. Otherwise, replace it if it's visibly sagging or your child is consistently uncomfortable. There's no need to replace on a fixed schedule if it still fits and supports them.
How much does a kids mattress cost at A2Z?
From around $99 for a single, rising for king single and with construction. The product grid above shows current pricing. Interest-free payment is available through Afterpay, Zip, Humm and Latitude.
Will a single kids mattress fit a bunk bed?
Most bunk beds take a standard single mattress — check your frame's stated size, and for bunks also check any maximum mattress depth the frame specifies. The single range is where to look.
Do you deliver kids mattresses, or can I pick one up?
Both. Stock is held in our Brisbane (Rocklea) warehouse with pick-up seven days a week, and Free Local Delivery is available on eligible orders from Rocklea — see our delivery details.
