Purchase and delivery
As with other mattress in a box products, the Sleep Republic Mattress can be conveniently ordered online (through the Sleep Republic website) and will be delivered to your door in a compact box.
It’s worth noting here that Sleep Republic offers the largest range of payment (and finance) options in the online mattress market (see ‘Payment & Finance’ options further down). These options even include cryptocurrency payments, and should accommodate the needs of all customers.
Sleep Republic also offers free delivery, Australia wide. They have one of the best delivery services on the market and can do ‘next day delivery’ to most major cities (see delivery times in the ‘Delivery information’ section further down).
The mattress was easy to remove from its packaging, and as usual, we recommend having two people available to unpack a mattress in a box. Unpacking the Sleep Republic Mattress takes 5-10 minutes, and we allowed 24 hours for the mattress to decompress before testing.
You can see this mattress in ‘real life’ in our video review here:
Aesthetically, the Sleep Republic Mattress presents beautifully. It combines simplicity with modern style, and gives off a distinct touch of luxury. Its brand name label and embroidery also give off plenty of class.
The Sleep Republic Mattress starts with a top cover made from a cashmere knitted fabric. This fabric feels smooth, luxurious, and is well ventilated.
This cover sits over a 30mm layer of gel infused memory foam and a 30mm layer of 100% natural latex.
These comfort materials sit over Sleep Republic’s signature ‘high definition’ pocket spring system. This support system contains 1,850 individual springs (queen size), more than double that of a standard mattress.
The springs around the perimeter of the mattress are made of firmer, high tensile steel and are designed to enhance edge support.
The side panels of the mattress use a 3D spacer fabric that is designed to maintain a high level of ventilation throughout the mattress.
Comfort and support
The top surface of this mattress (cashmere knitted fabric) feels soft, smooth, and luxurious. This top cover is also well ventilated and should help to regulate temperature during sleep.
These comfort layers (gel infused memory foam and natural latex) absorb body weight smoothly and provide lovely pressure relief. There is a real sense of balance and stability with this mattress, and it should appeal to most people.
The Sleep Republic Mattress should suit all sleeping positions (side sleepers, back sleepers, and stomach sleepers) but understandably, its suitability will vary between individuals.
Our team rated the Sleep Republic Mattress as a ‘medium-firm’ feel and 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. Mattress firmness will also vary depending on the type of bed base used.
We tested the Sleep Republic Mattress on the Naptime Base which is a quality bed base with rigid slats.
The ‘high definition’ pocket spring system provides outstanding spinal support, and we detected no undesirable sinking or sagging. The mattress has a 300kg weight limit (queen size) so it should suit people of all sizes.
The low level of partner disturbance on this mattress was also impressive, but this will vary. A larger mattress (e.g. king size) will usually involve lower amounts of motion transfer. Partner disturbance will also depend on the size of the occupants of the bed.
Sleep Republic’s ‘High Definition’ Pocket Spring System
The Sleep Republic Mattress responds nicely to normal sleep movements and we rated its level of responsiveness as ‘optimal’. In basic terms, this means that changing sleep positions (and intimate activities) 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.
Quite simply, this mattress has a superb balance of comfort, support, and responsiveness.
The finer details
The overall build quality and craftsmanship of the Sleep Republic Mattress is outstanding, and easily compares to many retail store mattresses double its price.
As we alluded to earlier, the mattress feels solid and stable. It is remarkable that a mattress of this quality comes compressed in a box.
Quite simply, this mattress has a superb balance of comfort, support, and responsiveness.
Edge support is excellent, thanks to the high tensile springs on the mattress perimeter. This should allow the user to use the full surface of the mattress (without fear of rolling off the edge).
The mattress sits 31cm high which is about average for a good quality, innerspring mattress. A queen size Sleep Republic Mattress also has a typical weight of approximately 50kgs.
The mattress also comes with handy side handles, making it easier to move and rotate. These handles are attached strongly, and should remain intact during use.
The cashmere blend fabric used in the top cover has been tested by the CSIRO (Commonwealth Scientific and Industrial Research Organisation) and has been cleared of any harmful chemicals.
The gel visco memory foam has been certified as non-toxic by CertiPUR-US®, one of the world’s leading authorities in foam and fabric testing.
What bed base should I use?
As with most mattresses, we recommend the Sleep Republic Mattress to be used with a bed base with rigid slats (not flexible/posture slats) with the slats no longer than 8 cm apart.
A base that we would recommend to be used with the Sleep Republic Mattress is the Sleep Republic Pro Base.
We do not recommend the Sleep Republic Mattress to be used with an adjustable (electric) bed base as this will void the warranty. Here is our full list of mattresses that are compatible with an adjustable bed base.
It’s worth noting here that use of an unsupportive mattress foundation will usually void the mattress warranty. Furthermore, mattress firmness, performance, and durability will vary with different bed bases.
Trial period and warranty
Sleep Republic offers a 100 night trial period, which is a typical trial period in the online mattress market. This means that you can return the mattress for a refund if you are not satisfied (conditions do apply).
This mattress also comes with a 12 year warranty to cover any faulty materials or workmanship. This is superior to the more common 10 year warranty among its competitors.
The Sleep Republic Mattress is available in all 7 Australian mattress sizes (super king, king, queen, double, king single, long single, and single size).
This is noteworthy, as Sleep Republic is one of only a few, bed in a box companies to offer the full collection of Australian mattress sizes.
Here are Australia’s standard bed (mattress) sizes in 2023.
The Sleep Republic Mattress is an outstanding mattress that is considered by our expert review team as the premier mattress in a box in Australia. It uses quality materials, is competitively priced, and comes with a 100 night free trial period.
Bedbuyer’s rating: 5 / 5

We’re the real deal
We’ve been dreaming up new designs for mattresses for over 20 years. We’ve refined our mattress design by constantly experimenting and investigating new technologies and materials. We’ve found a way to create pocket spring-loaded mattresses which can still fit in a box. Our hybrid mattress has been helping people all over Australia snooze soundly at night.
People often focus on foam mattresses, but we know pocket springs are better. They’re more supportive and minimise partner disturbance. That’s why we’ve packed as many as 2500 springs in one mattress, paired with comfortable and luxurious foam layers.
You can change your mind
If you don’t like our mattress, you can return it. No hidden conditions, pesky asterisks, or added fees.
How does a hybrid mattress feel?
The Sleep Republic hybrid mattress is a medium/firm feel. The best mattress for back pain offers a high level of support – which is exactly what we have designed. The HD Pocket Springs for support, married with the gel infused memory foam and latex pillow top for comfort make quite sure of it. Not too soft, not too hard; the best of both worlds.
Cashmere knitted fabric, gel infused memory foam & natural latex come together with our exclusive High Definition pocket spring system to create the perfect hybrid mattress feel.
From decades of experience in designing, making and selling mattresses we put it all together to bring you the best hybrid mattress design. Not content with the usual 630 springs in a Queen mattress, Sleep Republic created 1850 individually pocketed springs; supporting you precisely where it counts, eliminating partner disturbance and giving you the sleep you deserve.
The Sleep Republic Mattress is medium/firm feel. Why? Because years of customer feedback has told us that this is what the vast majority of people (even years after buying one) are happy with. Despite the notion that complete softness is required in order to achieve a perfect night’s sleep, we have found that the foam vs spring debate is moot: a soft mattress simply does not cut it. The same can be said for those contemplating a very firm mattress. A rock-hard mattress wears surprisingly thin after just a few nights.
The Sleep Republic Mattress offers a high level of support – which is exactly what we have designed with the Sleep Republic Mattress. The HD Pocket Springs for support, married with the gel infused memory foam and latex pillow top for comfort make quite sure of it. Not too soft, not too hard; the best of both worlds.
Don’t just take our word for it. Try it free for 100 nights and find out for yourself how to sleep well.
At Sleep Republic, everyone is equal and delivery is free everywhere (providing our deliverers can get there). No surcharges, no add-ons, country or city – delivery included. See details here.
The Sleep Republic Mattress uses state of the art compression technology. Our mattresses are rolled, wrapped and boxed with handles and wheels for easier moving. Seeing is believing – yes we really can get that mattress in there!
