Purchase and delivery
Just like other mattresses in a box, the Sleep Republic Kids Mattress can be ordered online and will be delivered to your door in a compact box. Delivery is free and shipping times are fast (see full delivery details below in our ‘Delivery’ section). ‘Next day delivery’ is available in major capital cities.
Unpacking the Sleep Republic Kids Mattress should only take 5-10 minutes, and we allowed it to decompress for 24 hours before testing.
The Sleep Republic Kids Mattress box arrived in good condition and the mattress was easy to remove from its packaging. With that said, we always recommend having two people to assist in the unpacking process.
From a visual perspective, the Sleep Republic Kids Mattress has a clean, fresh appearance. It sits 28cm high and uses a predominantly white colour theme.
Sleep Republic’s signature royal blue brand label also gives it a nice touch of class.
Mattress construction
From top to bottom, the Sleep Republic Kids Mattress starts with a cashmere and organic cotton knitted fabric cover. These natural fibres help to create a soft, durable sleeping surface and also allow good ventilation.
Underneath this top cover is a layer of premium density foam quilting and a layer of 100% natural latex. These materials have been added to provide a comfortable and durable comfort layer.
The main support structure of the Sleep Republic Kids Mattress is a high definition 5 zone pocket spring system. This spring unit has over 3 times more springs (1,081) than a standard pocket spring mattress (336). More springs generally helps to improve support and durability in a mattress, and can also help to reduce partner disturbance.
To enhance edge support, this mattress uses high tensile steel springs around the full perimeter of the mattress. This allows the user to use the entire surface of the mattress, without fear of falling off the edge.
Comfort and support
The Sleep Republic Kids Mattress is remarkably well balanced with comfort and support. Its top cover feels soft and smooth, and the comfort layers absorb body weight beautifully.
This mattress should suit toddlers from around the age of 2, all the way up to teenagers around the age of 16. With that said, this mattress is very suitable for co-sleeping and should accommodate most adults comfortably.
Our team rated it as a medium-firm feel, which is the recommended firmness level for children. More specifically, we rated it a 7 / 10 on the firmness scale (with 10 being the firmest).
Please note that our firmness ratings are just a guide and they do not necessarily relate to comfort. Furthermore, our firmness ratings are assigned based on Bedbuyer’s testing process and these may differ from firmness ratings given by individual companies.
The 5 zone spring system feels particularly strong and stable. It should offer excellent spinal support for children and most adults.
The Sleep Republic Kids Mattress responds very well to normal sleep movements and we rated its level of responsiveness as optimal. In basic terms, this means that changing sleep positions shouldn’t be any trouble.
Please note that our responsiveness scales are just a guide and preferred responsiveness levels will vary between individuals. It’s worth noting also that innerspring mattresses are generally more responsive than foam mattresses.
The finer details
The overall build quality of the Sleep Republic Kids Mattress is outstanding. Edge support is noticeably strong and this should prevent your child from rolling off the edge of the mattress – an important safety feature for any kids mattress.
The strong edge support is also highly practical as it allows kids and adults to sit on the edge of the mattress during story time or general play time.
In context of co-sleeping, partner disturbance is very minimal. This should improve the sleep experience for any child or adult, as a restless occupant shouldn’t cause much disruption. Of course, motion transfer on a mattress will depend on the size of the occupants of the bed, and is generally less on a larger size mattress.
One impressive design aspect of the Sleep Republic Kids Mattress are the handles located on the side of the mattress. These handles are attached strongly and will make carrying or lifting the mattress much easier.
Edge support is noticeably strong and this should prevent your child from rolling off the edge.
In terms of after sales service, Sleep Republic maintains its impressive 150 night trial period. This means that if you are not satisfied with this product, you can return it for a refund. The mattress also offers a solid 10 year warranty.
In terms of health and safety, it’s worth noting that the cashmere and organic cotton knitted fabric is certified with the OEKO-TEX STANDARD 100 as non-toxic. The premium density foam quilting is certified by CertiPUR-US Certified and the natural latex comfort layer is certified by the Eco-Institut, TUV Rheinland, and the OEKO-TEX STANDARD 100.
It’s fair to say that the Sleep Republic Kids Mattress is highly certified as being free of harmful chemicals, and is safe to bring into your home.
What bed base should I use?
As with most mattresses, we recommend the Sleep Republic Kids Mattress to be used with a solid bed frame with ‘rigid’ slats (such as the Sleep Republic Pro Base). It is recommended that the space between the slats does not exceed 8cm.
Sleep Republic Pro BaseNeither a bed frame with flexible (posture) slats or an adjustable bed base is recommended for this mattress. Here is our full list of mattresses that are compatible with an adjustable bed base.
It’s worth noting here that mattress firmness, performance, and durability will vary with different bed bases.
Available sizes
The Sleep Republic Kids Mattress is available in 3 sizes (single, king single, and double) so it should suit most children’s sleeping arrangements.
Here are Australia’s standard bed (mattress) sizes in 2025.
Final verdict
The Sleep Republic Kids Mattress is a true leader in the kids mattress market. It combines a high level of comfort with a first class spring system, and holds possibly the most non-toxic certifications of any mattress on the Australian market.
