Best Trundle Beds for Kids Australia

A trundle bed is one of the smartest buys for a kid's room. You get a full single bed for everyday sleeping and a second mattress that hides underneath, rolling out in seconds when a friend stays over or a sibling has a bad night. No blow-up mattress, no dragging a spare bed down the hall, and when the guest goes home the floor space comes straight back.

The trade-offs are worth knowing before you buy. Trundle mechanisms range from cheap fixed castors to smooth lockable wheels, the pull-out only takes a thin mattress (usually up to 10 to 14cm), and build quality swings from powder-coated steel to solid hardwood that outlasts childhood. We focused on trundle beds genuinely sold in Australia right now, checked the mattress fit and safety details, and picked one clear winner for each type of buyer.

What is the best trundle bed for kids in Australia?

The best trundle bed for kids in Australia in 2026 is the Fantastic Furniture Willa Single Bed with Trundle. It hits the sweet spot of the category: a natural solid pine single frame, a smooth sliding trundle for sleepovers, a sturdy 150kg rated base, and a price around $299 that most families can justify.

If floor space is tight, the IKEA SLAKT folds a bed, a guest bed and two storage drawers into one compact frame. For maximum storage the Amart Captain Jack adds three drawers alongside the trundle, the Fantastic Furniture Gecko covers the basics for well under $100, and the B2C Coco is built from solid hardwood to last through childhood.

1. Fantastic Furniture Willa Single Bed with Trundle (best overall)

Frame: Natural solid pine wood
Base: 13mm plywood slats
Trundle: Sliding rollers, pull-out single
Price: Around A$299, check current price
Check price

The Willa is the trundle bed most families should buy. You get a genuine solid pine single frame rather than the all-particleboard construction at this price, a slatted plywood base, and a pull-out trundle that glides out on sliding rollers with barely any effort. It looks like a proper bed, not a compromise, and the plain white finish suits almost any kids room.

It is rated to 150kg including the mattress, so it comfortably carries a growing child or an adult guest on the trundle, and it takes a standard single mattress up to about 14cm on top. That means you are not locked into an odd size or a thin foam pad for everyday sleeping.

Mattresses are sold separately for both the main bed and the trundle, and the trundle takes a slimmer mattress so it clears the frame when stored. For the money, it is the most complete and best-balanced trundle bed on this list.

Pick if...

You want one bed that does everything well: a solid pine single for every night and an easy roll-out for sleepovers, without overspending.

2. IKEA SLAKT Bed Frame with Underbed and Storage (best space-saving)

Type: Single frame with roll-out underbed
Storage: Two large drawers
Trundle mattress: Up to 10cm thick
Price: Around A$458, check current price
Check price

The SLAKT is the pick when the room is small and every centimetre counts. In one compact frame you get the everyday single bed, a roll-out underbed for a guest, and two big drawers for bedlinen and toys, so a single footprint does the job of a bed, a trundle and a chest of drawers.

IKEA designed it around kids and sleepovers, the underbed rolls out easily when a friend stays, and the whole thing has earned a strong owner rating across hundreds of reviews. The drawers are genuinely useful at about 85cm wide, which matters in a bedroom with no room for extra furniture.

It is built from particleboard and fibreboard rather than solid timber, and the underbed takes a mattress up to only 10cm thick, so keep the guest mattress slim. As a space-saver, though, nothing else here packs as much into as small a footprint.

Pick if...

You are working with a small bedroom and want a bed, a guest bed and drawers all in one tidy, compact unit.

3. Amart Captain Jack Single Trundle Bed (best with storage)

Type: Single with trundle plus drawers
Storage: Three built-in drawers
Size: 199 x 98cm, 92cm headboard
Price: Around A$899, check current price
Check price

If your child's room has to hold everything in one piece of furniture, the Captain Jack is the answer. On top of the pull-out trundle for sleepovers it packs three full drawers into the base, so clothes, bedding and toys all disappear into the bed instead of spilling across the floor.

It is a substantial, well-finished piece at around 72kg, with a classic white look that works from primary school through to the teens, and it carries a three-year guarantee. The trundle rolls out from beneath for a second sleeper and tucks away again when the guest leaves.

The frame is wood and MDF rather than solid hardwood, and at around $899 with mattresses sold separately it is the priciest bed here. For a small room that needs to double as storage, that buys a genuine all-in-one solution.

Pick if...

You need one bed to also be the wardrobe and toy box, with a trundle for guests and drawers for everything else.

4. Fantastic Furniture Gecko Single White Trundle Bed (best budget)

Frame: Powder-coated steel
Wheels: Lockable castors
Profile: 98 x 189cm, 12cm high
Price: Around A$99, check current price
Check price

You do not need to spend much to solve the sleepover problem, and the Gecko proves it. It is a low steel trundle on lockable wheels that slides under most existing single beds, so for well under $100 you add a second bed without adding a second frame or rearranging the room.

The powder-coated steel is chip resistant and easy to wipe down, the lockable castors stop it wandering once it is rolled out, and at just 12cm high it disappears under the main bed with about 28cm of clearance to work with. It ships flat and is quick to assemble.

It is a trundle only, so you already need a bed to store it under, and it takes a slim mattress rather than a plush one. As a cheap, no-fuss way to be sleepover-ready, it is the sensible starting point.

Pick if...

You already have a single bed and just want an affordable, tuck-away second bed for guests and sleepovers.

5. B2C Coco King Single Bed with Trundle (best solid timber)

Frame: Solid hardwood, natural and white
Base: Plywood slats
Trundle: Pull-out on directional wheels
Price: Around A$577, check current price
Check price

When you want a bed that lasts through childhood and beyond, the Coco is the one to buy. B2C builds it from solid hardwood rather than the chipboard and vinyl used by many rivals, so the frame stays tight and rattle-free through years of jumping, sleepovers and hand-me-downs.

The king single top bed gives a bit more room than a standard single, and the trundle runs on eight directional wheels so it can be set up on either side of the bed to suit the room, then pulled right out to clean underneath. The natural timber and white finish is clean and grows up well with the child.

It is a king single rather than a standard single, so plan your mattress and sheets accordingly, and mattresses are sold separately. For families who would rather buy once, the solid hardwood build is worth the premium over particleboard beds.

Pick if...

You want a hard-wearing solid timber bed that survives childhood and holds its looks, and you are happy to pay a little more once.

How we choose trundle beds for kids

There is no lab-coat theatre here, just the same process applied to every product. For kids trundle beds specifically we:

• Confirmed real Australian availability — every pick is currently sold in Australia with a working product page, and we dropped models we could not confirm were in stock here.
• Checked the trundle mechanism — how smoothly the second bed rolls out, whether the wheels lock, and how cleanly it stows away under the main bed.
• Read the mattress fit — the size and maximum thickness each trundle takes, because a mattress that is too deep will not clear the frame.
• Weighed materials and safety — solid timber versus particleboard, weight ratings, stable bases and rounded finishes for a child's room.
• Aggregated verified owner reviews across retailer listings and Australian communities, and re-checked prices and stock at this update.

What to look for in a kids trundle bed

1. The trundle mechanism

The whole point is a second bed that rolls out easily and stows away cleanly. Look for smooth rollers or castors, ideally lockable so the bed does not drift once it is out, and check the trundle sits flush under the main frame when stored.

2. Mattress fit and thickness

Trundles only take a slim mattress, usually up to 10 to 14cm, so it clears the frame when pushed back under. Check the maximum thickness and the mattress size before you buy, and remember most beds sell the mattresses separately.

3. Materials and durability

Solid pine or hardwood frames survive years of jumping and sleepovers far better than all-particleboard beds, though they cost more. Steel trundles are light and wipe clean. Match the build to how hard the bed will be used.

4. Storage

In a small room, a bed that also holds bedding and toys earns its space. Some trundle beds add built-in drawers alongside the pull-out, turning one piece of furniture into a bed, a guest bed and a chest of drawers.

5. Safety and weight rating

Check the weight rating if an adult guest might use the trundle, and favour stable bases, rounded edges and a low trundle profile. Lockable wheels add a margin of safety once the second bed is rolled out.

FAQs

What is a trundle bed?

A trundle bed is a single bed with a second, lower bed that stores underneath on wheels. You roll the trundle out when someone stays over and slide it back under the main bed the rest of the time, so you get two beds in the floor space of one.

What size mattress does a trundle take?

Most trundles take a single mattress, but a slim one, usually up to 10 to 14cm thick, so it clears the frame when stored. Always check the listing for the exact size and maximum thickness, as a too-deep mattress will stop the trundle sliding away.

Are trundle beds good for small rooms?

Yes, they are one of the best space-savers for a kids room. A trundle gives you a spare bed for sleepovers without a second frame taking up floor space, and models like the IKEA SLAKT add storage drawers so a single unit does the work of several.

Can an adult sleep on a kids trundle?

Often, but check the weight rating and mattress. A bed like the Willa is rated to 150kg including the mattress, which comfortably suits an adult guest, while lighter steel trundles are better kept for children. Match the trundle mattress thickness to the frame for comfort.

Do trundle beds come with mattresses?

Usually not. Most trundle beds on this list sell the main and trundle mattresses separately, so budget for two mattresses. A few daybed packages include them, but always confirm on the product page before you buy.
