1. Sleep Republic LUXE Mattress
Best Overall 🥇
$1,839.05 (Queen)
In an extremely competitive market, deciding on a clear standout is never easy. Nevertheless, we were very comfortable in awarding the Sleep Republic LUXE Mattress as Australia’s ‘Best Overall’ Mattress in a Box in 2026.
At its core, the LUXE features multiple comfort layers including gel-infused memory foam, responsive foams, and a layer of natural latex, all sitting above a 7-zone pocket spring system. This layered design is intended to provide pressure relief while maintaining strong, targeted support through the spine and key pressure points.

In our hands-on testing, the mattress delivered a balanced medium feel, which should suit most sleeping positions including side, back, and stomach sleepers. The surface feels plush and inviting, while the underlying spring system provides a stable and supportive base without feeling overly firm.
We were particularly impressed by the edge support and overall stability of the mattress. Motion isolation was also very good for an innerspring design, meaning movement from a partner is unlikely to be overly disruptive during the night.
With a generous 150-night trial period and a 12-year warranty, the Sleep Republic LUXE offers both comfort and peace of mind. For sleepers wanting a premium, well-rounded mattress in a box with strong performance across the board, it stands out as a top-tier option.
2. Eva Mattress
Best for the Money 💵
$925 (Queen)
The Eva Mattress (also known as the Eva Comfort Classic Mattress) is a well-established innerspring mattress that combines memory foam, latex, and pocket springs into a supportive medium-firm design.
In terms of construction, the Eva Mattress uses a breathable fabric cover, gel-infused memory foam for pressure relief, a layer of natural latex for responsiveness, and a 5-zone pocket spring system underneath. This combination aims to balance comfort and support while promoting airflow and reducing partner disturbance.
Use code BEDBUYER275 to unlock this price
During our hands-on testing, the Eva Mattress delivered a consistent medium-firm feel, which should suit most side, back, and stomach sleepers. The surface provides good pressure relief without feeling overly soft, while the spring system feels robust and supportive, particularly through the lower back and hips.
We found edge support to be solid for this price category, and motion isolation was better than expected for an innerspring mattress. While it’s a relatively heavy mattress, this reflects the strength of the spring unit and overall build quality, rather than being a drawback.
With a 100-night trial, fast delivery to most metro areas, and a very sharp price when discounts are applied, the Eva Mattress remains one of the best value mattress-in-a-box options in Australia. It’s a sensible, dependable choice for sleepers wanting comfort, support, and affordability in one package.
Here is our full review (which includes a video review).
3. Dusk&Dawn Harmony
Best Premium 💎
$2,463.12 (Queen)
The Dusk&Dawn Harmony Mattress is an Australian-made hybrid mattress designed to offer premium comfort with a simple firmness customisation feature.
Its construction combines plush comfort foams with a 5-zone pocket spring system, reinforced edge support, and a breathable border to encourage airflow. The materials and finishes feel refined and reflect the brand’s focus on durability and long-term performance.
Use code BEDBUYER12 to unlock this price
A key feature of the Harmony is its flippable comfort layer, which allows sleepers to switch between a medium-firm and medium-soft feel within the same mattress. Our hands-on testing found both options comfortable and well balanced, with only subtle differences between the two.
In use, the mattress feels stable, supportive, and responsive, with good pressure relief and low partner disturbance. Edge support is particularly strong for a mattress in a box, helping maximise the usable sleep surface.
With Australian manufacturing, adjustable comfort, and a premium overall feel, the Dusk&Dawn Harmony is a strong choice for sleepers wanting flexibility without compromising on build quality. A 100-night trial and solid warranty round out the offering.
4. DuuDuu Quokka Mattress
Best for Backs 🧍
$1,615 (Queen)
The DuuDuu Mattress is a high-quality innerspring mattress that has clearly been designed with durability and spinal support in mind.
At the surface, the TruCool fabric feels smooth and cool to the touch, helping with temperature regulation during sleep. Beneath this sit several supportive foam layers and a naturally sourced latex layer, which adds resilience, breathability, and reduced motion transfer.
Use code BEDBUYER50 to unlock this price
During our hands-on testing, the DuuDuu Mattress delivered a consistent medium-firm feel, which should suit a wide range of sleepers including side, back, and stomach sleepers. The mattress provides excellent back support, with the spring system offering a strong, responsive feel that adapts well to normal sleep movements.
One of the standout features of the DuuDuu Mattress is its edge support. The reinforced perimeter creates a very stable edge, allowing full use of the mattress surface and making sitting or sleeping near the edge feel secure. Motion isolation was also impressive for an innerspring design, so partner disturbance should be minimal for most couples.
Overall, the DuuDuu Mattress stands out for its build quality, thoughtful construction, and strong support characteristics. With certified non-toxic materials, a 100-night trial, and a solid warranty, it is a compelling option for sleepers looking for a supportive, well-engineered mattress in a box.
5. Peace Lily Hybrid Mattress
Best Hybrid 🧬
$1,099 (Queen)
The Peace Lily Hybrid Mattress is a true hybrid mattress that places a strong emphasis on natural materials, sitting alongside the brand’s popular all-latex model. It is designed for sleepers who want the buoyant, responsive feel of latex combined with the support of a pocket spring system.
At the surface, the mattress uses a GOTS-certified organic cotton cover and wadding, giving it a soft, natural feel. Beneath this sits a generous layer of natural latex, sustainably sourced and certified as non-toxic, which provides comfort, durability, and the distinctive elasticity that latex is known for.
During our hands-on testing, the Peace Lily Hybrid Mattress delivered a consistent medium-firm feel, which should suit most sleeping positions. The latex creates a responsive sleep surface rather than a deep sink, while the pocket springs provide reliable back support and overall stability.
Edge support is solid thanks to reinforced springs and a latex border, allowing good use of the mattress surface. Motion transfer is present but well controlled, and the mattress responds easily to movement, making it practical for combination sleepers and couples.
With its strong focus on certified non-toxic materials, organic fabrics, and natural latex, the Peace Lily Hybrid Mattress stands out for health-conscious buyers. Combined with a 100-night trial and a lengthy 15-year warranty, it offers a well-balanced option for those wanting comfort, support, and peace of mind.
6. Sleeping Duck Mattress
Best for Couples 👫
$1,649 (Queen)
The Sleeping Duck Mattress (Mach II) is one of the most recognisable and widely used mattresses in Australia, known for its clever design and exceptional level of customisation. It has built a strong reputation for offering flexibility, quality construction, and broad appeal across different sleeper types.
At its core, the Sleeping Duck is an innerspring mattress that combines breathable fabric, multiple foam comfort layers, and a robust multi-zoned pocket spring system. The reinforced perimeter support adds stability around the edges, while the overall build feels solid, refined, and thoughtfully engineered.
What truly sets the Sleeping Duck apart is its unmatched firmness adjustability. Sleepers can configure the mattress as medium, firm, or even request additional inserts to fine-tune different zones of the body. Couples can also opt for split firmness in larger sizes, allowing each side of the bed to feel different if needed.
In our hands-on testing, the mattress performed well across all firmness options, offering reliable back support and good pressure relief when the correct configuration is chosen. Responsiveness is strong, making it easy to move and change positions, while partner disturbance remains low for an innerspring design.
With its innovative customisation system, strong build quality, and consistent performance, the Sleeping Duck Mattress remains a standout option for couples and those with changing comfort needs. A 100-night trial and solid warranty further reinforce its position as one of Australia’s most versatile mattress-in-a-box options.
Here is our full review (which includes a video review).
7. Koala Mattress
Best Foam 🛏️
$1,124.10 (Queen)
The Koala Mattress is one of Australia’s most recognisable foam mattresses, known for its simple design, strong brand presence, and focus on non-toxic materials. The current version, released in 2024, builds on earlier models with improved construction and a more refined overall feel.
This is an all-foam mattress that uses a breathable TENCEL™-blend cover, a responsive Kloudcell™ comfort layer, and a zoned support base designed to assist with spinal alignment. The materials feel dense and supportive, while still offering enough cushioning for everyday comfort.
Use code BEDBUYER10 to unlock this price
A key feature of the Koala Mattress is its adjustable firmness design. Sleepers can choose between a medium-firm or firm feel by flipping the comfort layer, with a partner preference option also available in larger sizes. Our hands-on testing found the difference between the two firmness options to be noticeable, though not dramatic.
In use, the mattress provides good pressure relief and strong motion isolation, which should suit couples and light sleepers. As with most foam mattresses, responsiveness is lower than an innerspring design, so changing positions can require a little more effort, particularly for heavier sleepers.
With its 120-night trial, non-toxic certifications, and flexible firmness options, the Koala Mattress remains a popular choice for those wanting a simple, foam-based mattress in a box. It is best suited to sleepers who value low partner disturbance, eco-conscious materials, and a slightly firmer overall feel.
8. Sleep Firm Ultra Mattress
Best Firm Feel 🪵
$1,649.05 (Queen)
The Sleep Firm Ultra Mattress is the mid-range option in the Sleep Firm lineup and is designed specifically for sleepers who genuinely prefer an ultra-firm feel. It sits above the entry-level Sleep Firm Mattress and is one of the firmest mattress-in-a-box options currently available in Australia.
This is an innerspring mattress built around a reinforced 5-zone pocket spring system, paired with ultra-dense comfort foams to maximise support and stability. The overall construction feels robust and purposeful, with a strong emphasis on maintaining spinal alignment and resisting sink or sag over time.
Use code BBEXTRA5 to unlock this price
During our hands-on testing, the Sleep Firm Ultra delivered exactly what it promises. The feel is immediately firm, with very little compression under body weight, yet it avoids feeling harsh or uncomfortable thanks to a small amount of surface responsiveness. Our expert team rated it at 9.5 out of 10 for firmness, placing it firmly in the extra-firm category.
This firmness profile is best suited to back sleepers, heavier individuals, or anyone who actively dislikes a soft or cushioning sleep surface. The spring system feels stable and supportive across the entire mattress, and responsiveness is excellent, making movement and position changes easy throughout the night.
With Australian manufacturing, a 150-night trial, and a long 15-year warranty, the Sleep Firm Ultra Mattress offers strong value for those seeking a genuinely firm sleep experience. It is a standout option for sleepers who know they want an ultra-supportive mattress and are comfortable with minimal surface softness.
9. Peace Lily Latex Mattress
Best Latex 🌿
$1,599 (Queen)
The Peace Lily Latex Mattress is a natural, eco-focused mattress made entirely from 100% natural latex and certified organic cotton. It is designed for sleepers who want a chemical-free, durable sleep surface without compromising on comfort or support.
This is a full latex mattress that uses multiple layers of natural Dunlop latex, wrapped in a soft organic cotton cover. The materials feel premium and substantial, and the construction reflects a strong focus on sustainability, longevity, and non-toxic manufacturing.
A standout feature of the Peace Lily Latex Mattress is its flippable design, which allows sleepers to choose between a medium feel on one side and a firmer feel on the other. Our hands-on testing found both sides well balanced, offering good pressure relief while maintaining excellent spinal support.
Latex gives the mattress a responsive, buoyant feel that differs from traditional foam, making it easier to move and change positions during sleep. While edge support is naturally softer than an innerspring design, it remains respectable for a latex-only mattress, and partner disturbance is minimal.
With its impressive list of non-toxic certifications, optional latex topper, and industry-leading 25-year warranty, the Peace Lily Latex Mattress is a standout option for eco-conscious sleepers. It is particularly well suited to those seeking a natural, supportive, and highly durable mattress in a box.
10. Valmori Hybrid Mattress
Best on a Budget 💰
$765 (Queen)
The Valmori Hybrid Mattress II is a well-priced, true hybrid mattress that combines foams, latex, and pocket springs into a single, cohesive sleep system. Unlike many mattresses that simply layer foams over a spring base, this design integrates its materials in a way that delivers a balanced and consistent feel across the surface.
One of the immediate standouts with the Valmori Hybrid Mattress II is the overall value package. In addition to the mattress itself, Valmori includes a generous set of complimentary pillows, which are genuinely good quality and not just a throw-in. Ordering online is straightforward, delivery is free to most areas, and setup is quick and simple once the mattress is unboxed.
No code required – price already discounted
In terms of comfort, the Valmori Hybrid Mattress II has a soft, inviting surface with a medium feel. The blend of gel memory foam, natural latex, and soft foams creates a slightly spongy sensation that offers good pressure relief while still feeling supportive underneath. During our hands-on testing, the mattress felt well suited to most sleeping positions, provided a medium feel is what you’re after.
Support comes from a 7-zone pocket spring system that provides reliable spinal alignment and keeps partner disturbance to a minimum. The mattress feels stable and responsive, making it easy to change positions through the night, and we rated its responsiveness in the optimal range during testing.
Overall, the Valmori Hybrid Mattress II is a solid all-rounder that delivers strong value for money. With its integrated hybrid construction, medium comfort profile, non-toxic certifications, and long 15-year warranty, it’s a sensible option for shoppers looking for a balanced mattress in a box without stretching the budget.
11. Sleep Republic Kids Mattress
Best for Juniors 🧒
$661.55 (Single)
The Sleep Republic Kids Mattress is an outstanding option for families looking for a high-quality kids mattress that genuinely grows with the child. Designed to suit toddlers through to teenagers, it also performs exceptionally well for adults, making it a strong choice for families who regularly co-sleep.
Based on the construction of the award-winning Sleep Republic Mattress, this kids version feels far more substantial than many competing children’s mattresses. Delivery is fast and free, unpacking is straightforward, and once expanded, the mattress presents with a clean, modern look that feels reassuringly solid rather than lightweight or flimsy.
Use code BBEXTRA5 to unlock this price
In terms of comfort, the Sleep Republic Kids Mattress strikes an excellent balance between cushioning and support. The combination of premium quilting, natural latex, and a high-definition pocket spring system allows the mattress to absorb body weight smoothly while maintaining a stable, supportive feel. During testing, it felt comfortable for children and adults alike.
Support is a real strength here. The dense 5-zone pocket spring system feels robust and stable, and the medium-firm feel aligns well with firmness levels typically recommended for children. We rated it a 7 out of 10 for firmness, which should suit a wide range of sleepers while still providing excellent spinal support.
Overall, the Sleep Republic Kids Mattress stands out for its build quality, safety credentials, and versatility. With strong edge support, minimal partner disturbance, extensive non-toxic certifications, and a generous 150-night trial, it’s one of the most impressive kids mattresses currently available in Australia – particularly for families who value co-sleeping support.
12. Macoda Mattress
Recommended ✅
$1,200 (Queen)
The Macoda Mattress is a modern, comfortable mattress-in-a-box that blends responsive comfort foams and a supportive spring system. Released in 2024, it builds on its predecessor’s strong reputation for delivering one of the most comfortable sleeps in the market.
A standout feature is the adjustable firmness setup, which allows sleepers to reconfigure the internal foam layers to suit soft, medium or firm preferences. This customisation option makes it appealing for couples and anyone who likes to fine-tune their comfort.
Use code BEDBUYER to unlock this price
In our hands-on testing, the default medium setting delivered plush pressure relief while maintaining reliable support. Side sleepers in particular should appreciate its cushioning, while the firmer configurations still offered solid alignment for back and stomach sleepers.
Responsiveness was strong across all configurations, making it easy to change positions throughout the night. Partner disturbance was minimal, and although edge support was softer in the plush setup, the mattress felt stable across the full surface.
With solid build quality, practical handles, non-toxic certifications and competitive pricing, the Macoda Mattress remains a very compelling choice for those who prioritise comfort and adaptability in a mattress-in-a-box.
13. Sleep Republic Mattress
Recommended ✅
$1,269.05 (Queen)
The Sleep Republic Mattress is one of Australia’s most awarded mattress-in-a-box options and continues to be a standout all-rounder. It sits in the middle of Sleep Republic’s range, offering a strong balance of comfort, support and durability at a competitive price point.
In our hands-on testing, the mattress delivered a very comfortable medium-firm feel that should suit most sleepers. The combination of comfort foams and natural latex provides excellent pressure relief, while the pocket spring system underneath gives the mattress a stable, well supported feel.
Use code BBEXTRA5 to unlock this price
The high-definition pocket spring system does a great job of supporting the spine and limiting unwanted sinkage. We found it suitable for side, back and stomach sleepers, provided the medium-firm feel aligns with individual preference. Responsiveness was also excellent, making it easy to change positions through the night.
Edge support is a real strength here. The reinforced perimeter allows sleepers to comfortably use the full surface of the mattress without feeling unstable, and it also performs well for sitting on the edge. Partner disturbance is low, so movements from a restless sleeper are unlikely to be an issue.
With strong build quality, excellent safety certifications, fast delivery and a generous 150-night trial, the Sleep Republic Mattress remains one of the safest and most reliable choices in the mattress-in-a-box category. It’s a well refined option that continues to justify its long list of awards.

15. Atlantis S1 Mattress
Recommended ✅
$1,679 (Queen)
The Atlantis S1 Mattress is an Australian-made innerspring mattress that stands out for its genuinely adjustable firmness system. The mattress can also be ordered either compressed in a box for fast delivery or delivered unboxed in the traditional manner.
From a design perspective, the Atlantis S1 feels premium and thoughtfully constructed. The Sea-Soft fabric cover, made from Tencel and Seaqual fibres (derived from rescued ocean plastics), is soft, breathable, and one of the nicest covers we’ve tested. The mattress sits at a generous 34cm high and has a polished, modern appearance.
Use code BEDBUYER220 to unlock this price
In terms of comfort and support, the Atlantis S1 performs exceptionally well across all firmness options. During testing, the pocket spring support system delivered strong spinal support and good stability, while the HybridFlow comfort layer ensured pressure relief without excessive sink. Regardless of firmness selection, responsiveness was rated in the optimal range.
What truly sets this mattress apart is its post-purchase customisation. Buyers can choose soft, medium, or firm at checkout – including a half-half option for couples – and if it’s not quite right, additional foam layers can be requested within the trial period to refine the feel. This makes the Atlantis S1 particularly appealing for couples and those with specific support needs.
Overall build quality is excellent, with strong edge support, durable materials, and impressive non-toxic and environmental certifications. Combined with the option of fast “fresh box” delivery and a 100-night trial, the Atlantis S1 Mattress is one of the most adaptable and well-engineered mattresses currently available in Australia.
Additional info – buying a mattress in a box
When buying a mattress in a box online, it’s important to understand how this type of mattress works and what to expect from the process.
Below is some handy information to help you make a confident decision.
What is a mattress in a box?
A mattress in a box is simply a mattress that has been compressed by heavy machinery so it can be rolled or folded and packed into a box.
This compression method makes storage and transport far more economical and, for many buyers, makes it easier to move the mattress into the home – particularly in apartments or upstairs bedrooms.
Mattresses in a box are typically ordered online and delivered directly to your door, often within days. Once unpacked, the mattress expands and gradually returns to its full size and shape, performing just like a traditionally delivered mattress.
It’s worth noting that there will be a reasonable amount of packaging (cardboard and plastic wrapping) to dispose of, so some forward planning with bin space is recommended.
Are mattresses in a box any good?
The short answer is: yes – and no.
The mattress in a box market covers a huge range of products, from excellent quality mattresses to very basic, budget options. Just like traditional retail stores, there are great products and not-so-great products available.
For example, compare the And Sleep Prime and the Kmart Bonnell Spring Mattress.
Both are mattresses in a box, yet the difference in comfort, support, materials, and durability is significant.
The And Sleep Prime uses higher quality comfort layers and a more sophisticated spring system, delivering better pressure relief, support, and responsiveness.
By contrast, the Kmart mattress uses cheaper materials and a basic spring system, and is unlikely to provide adequate comfort or longevity for regular adult use.
Rather than generalising mattresses in a box as “good” or “bad”, the key is to choose a mattress that suits your needs, preferences, and budget – regardless of how it’s delivered.
Why are mattresses in a box so popular?
Mattress in a box products have completely changed the way Australians shop for mattresses.
They’re typically more affordable, delivery is usually free, and many brands now offer very fast shipping – sometimes even next-day delivery. This is a big contrast to the traditional retail experience, where delivery can take several weeks.
Another major driver of popularity is the free trial period. Many mattress in a box brands allow you to sleep on the mattress at home for an extended period and return it for a refund if it’s not right for you.
This combination of convenience, price transparency, and reduced risk has made mattresses in a box a very popular choice across Australia.
How much do mattresses in a box cost?
The average price of a mattress in a box in Australia is around $1,250 for a queen size.
This is noticeably lower than the average retail store mattress, which often sits around $3,000.
Mattress in a box products have completely changed the way Australians shop for mattresses.
As you’ll see from our award list above, prices vary widely depending on materials, construction, and brand positioning. To help narrow your options, we’ve assigned award categories (such as Best for Couples or Best for the Money) to highlight mattresses that perform particularly well in specific areas.
We always recommend choosing a mattress based on your comfort needs and sleeping preferences, rather than price alone.
Trial periods – what should I know?
Most mattresses in a box sold in Australia come with a free trial period, typically around 100 nights.
This allows you to return the mattress for a refund if you’re not satisfied, giving you peace of mind when buying online.
However, trial periods do come with conditions. For example:
-
The mattress must be kept in pristine condition
-
A minimum trial period often applies (e.g. 14–30 nights)
-
In some regional or rural locations, you may need to assist with donation or collection
We strongly recommend checking the trial conditions on the brand’s website or in their FAQ section before purchasing.
Foam vs innerspring mattresses in a box
There’s a common misconception that all mattresses in a box are foam mattresses. This isn’t true.
In fact, the majority of mattresses in a box sold in Australia are innerspring mattresses (around 54%). Foam mattresses make up roughly 43% of the market, with latex mattresses accounting for the remaining small percentage.
Mattress type preference comes down to personal comfort, body weight, sleeping position, and how responsive you like your mattress to feel.
How long does decompression take?
Once the packaging is removed, most mattresses in a box expand very quickly and regain their shape over time.
We recommend having two people available during unpacking, as mattresses can expand suddenly once the plastic is cut.
In most cases, we suggest allowing 24–48 hours for full decompression. That said, many mattresses are comfortable to sleep on within a few hours of being unpacked.
Warranties
Almost all mattresses in a box come with a warranty, typically around 10 years, though this varies by brand.
Warranties usually cover manufacturing defects and excessive body impressions, but they often have conditions. Common exclusions include:
-
Impressions below a certain depth (e.g. less than 30mm)
-
Use on an unsupportive bed base
-
Damage caused by incorrect handling
Warranty details are usually found in the FAQ section or at the bottom of the brand’s website, and it’s worth reviewing these before buying.

FAQ – Frequently asked questions
Can you roll a mattress in a box back into the box?
No, mattress-in-a-box products are compressed and rolled by heavy machinery, and it’s not possible for humans to manually get them back into their original packaging. If you need to return your mattress, it will typically be collected in its fully expanded form by a charity or the company’s logistics team.
Can I return my mattress in a box if I don’t like it?
Yes, in most cases, if you’re not satisfied with your purchase, you can return the mattress for a full refund, provided you meet the company’s conditions. Common conditions include returning the mattress in pristine condition (sometimes with the original packaging). In some cases, customers in regional or rural areas may be responsible for return shipping costs.
Will mattresses in a box last as long as in-store mattresses?
It depends. The longevity of a mattress in a box largely depends on the quality of materials and construction. Many high-quality mattress-in-a-box products are designed to be just as durable as those purchased in-store. However, lower-quality options may not last as long. In general, a well-made mattress in a box can offer comparable durability to traditional mattresses.
How easy and reliable is the return process for mattresses in a box?
In general, the return process for most mattress-in-a-box companies in Australia is reliable and efficient. Brands like Koala, Sleeping Duck, Sleep Republic, and Eva are known for their trustworthy and straightforward return and refund systems. Essentially, most companies make the process as hassle-free as possible so returning your mattress is relatively straightforward in most cases.
Do mattresses in a box have a smell or odour when first opened?
Yes, many mattresses in a box—and even non-boxed mattresses—can have a slight new product smell when first unpacked, often referred to as off-gassing. This odour doesn’t necessarily indicate toxicity and typically dissipates within a few hours to a few days. Many beds in a box have reputable non-toxic certifications for peace of mind.
Are mattresses in a box suitable for all bed bases?
As with all mattresses, we highly recommend using a bed base with rigid slats or solid panel slats. This ensures the best support and foundation, leading to optimal performance and longevity of the mattress. Flexible or posture slats generally don’t provide the necessary support and can lead to sagging, potentially voiding the mattress warranty.
How do I properly care for my mattress in a box?
As with all mattresses, we recommend rotating the mattress regularly, about every three to six months. This helps to minimise wear and tear and ensures even support across the mattress surface. Using a mattress protector is also highly recommended to keep the mattress clean, hygienic, and to potentially extend its lifespan.
