Who Is Origin Best For?
Origin is best for hot sleepers and back pain sufferers. The signature HexaGrid™ layer provides excellent cooling and pressure relief, while the orthopaedic layering supports natural spinal alignment.
Why Is Origin a Better Alternative to "Retail Store" Brands?
It solves the problem of "Middleman Markups."
Usually, to get a 6-layer hybrid mattress with cooling gel and micro-springs, you would have to spend $3,000+ at a showroom (paying for their rent and commissions). Origin cuts out the middleman, giving you the same high-end "hotel" tech for a fraction of the price.
What Are The Key Features?
- HexaGrid™ Layer: Dissipates body heat and relieves pressure points.
- Antigravity Springs: Micro-springs for targeted back support.
- Tencel™ Cover: Ultra-soft, breathable, and hypoallergenic.
- 15-Year Warranty: One of the longest warranties in the industry.
What's the Boxing Day Deal?
Origin has launched a massive up to 54% off sitewide. Use our exclusive code TOP5-5%OFF to take an extra 5% off the sale price.
2. Newentor – Best Value Hybrid Deal
Newentor is aggressive this Boxing Day. With savings up to 65%, this is the best pure "dollar-saving" deal on the market for a high-quality hybrid.
More details
Eco-friendly
Adjustable design

Who Is Newentor Best For?
Newentor is best for people who are unsure what firmness they need. The Hybrid Mattress Pro features a unique switchable firmness layer, allowing you to adjust the feel at home to suit your back or side sleeping preference.
Why Is Newentor a Better Alternative to Cheap Foam Mattresses?
It solves the problem of "Sinking & Sweating."
Budget mattresses are often just blocks of foam that trap heat and sag quickly. Newentor is a true hybrid—meaning it uses pocket springs for airflow and durability, plus bamboo charcoal foam to wick away moisture. It’s a health-focused upgrade over standard budget foam.
What Are The Key Features?
- Switchable Firmness: Flip the internal layers to change the feel.
- 7-Zone Support: Softer at the shoulders, firmer at the hips.
- Bamboo Charcoal Fabric: Naturally antibacterial and moisture-wicking.
- Anti-Slip Base: Keeps the mattress secure on your frame.
What's the Boxing Day Deal?
Newentor’s Christmas & Boxing Day sale offers up to 65% off. This is an automatic discount—no code required.
3. Emma – Best All-Rounder Deal
Emma is a safe bet for almost anyone. Their "Comfort" mattress is Australia’s most awarded for a reason, and the extra discount code makes it a steal.
More details
Medium-firm support allows comfort for all sleep positions
10 year warranty & risk-free 150 night trial
Breathable & washable top cover
Award-winning mattress
Customer support is limited
They don't dispose of old mattresses for you
Lacking edge support
Who Is Emma Best For?
Emma is best for couples and renters. The mattress is engineered for "Zero Motion Transfer," meaning you won't feel your partner move. It’s also lightweight and easy to move between homes.
Why Is Emma a Better Alternative to Buying Blind?
It solves the risk of "Buyer's Remorse."
Buying a mattress is stressful—what if you hate it in a week? Emma offers a 100-night risk-free trial. If it doesn’t work for you, they pick it up and give you a full refund. It is the safest way to buy a bed in 2025.
What Are The Key Features?
- Airgocell® Technology: Breathable foam that stays cool.
- HRX Support Foam: Prevents sagging and supports the spine.
- Removable Cover: Machine washable for easy cleaning.
- 100-Night Trial: Risk-free testing in your own home.
What's the Boxing Day Deal?
Emma is offering up to 30% off. Readers can stack code Top5Mattresses10 for an additional 10% off, bringing the price down significantly.
4. Sleeping Duck – Best Premium Customisation
Sleeping Duck rarely offers discounts, making their Boxing Day bundle a rare opportunity to buy into their premium ecosystem for less.
More details
Choose your own firmness and even make adjustments for free
Half-half firmness caters to couples
Award-winning customer service
All foams are GECA approved
Pressure foaming makes Sleeping Duck’s proprietary foam very breathable
The cover is machine washable
May not be suitable for larger-bodied sleepers
Who Is Sleeping Duck Best For?
Sleeping Duck is best for perfectionists. If you are terrified of buying a mattress that is "too soft" or "too firm," their Mach II mattress allows you to swap out foam layers for free during the trial until it's perfect.
Why Is Sleeping Duck a Better Alternative to "One-Firmness" Beds?
It solves the problem of "Guestimating" Comfort.
Most brands sell you a "Medium-Firm" bed and hope you like it. Sleeping Duck actually lets you change the firmness density after you buy it. You can even have "Half-Half" firmness for couples with different needs.
What Are The Key Features?
- ComponentAdapt System: Swap layers to adjust firmness.
- Antigravity Foam: High-density foam that feels responsive, not sticky.
- Breathable Cover: Bamboo fabric for maximum cooling.
- Indestructible Springs: Twice tempered steel for longevity.
What's the Boxing Day Deal?
Sleeping Duck is offering a bundle deal with up to $814 off sleep systems (Mattress + Bed Frame bundles).
5. Onebed – Best Adjustable Foam Deal
Onebed offers a unique proposition: an all-foam mattress that you can re-arrange yourself.
More details
Comfortable sleeping experience
Customisable firmness options in some models
Great value for money
Long warranty and money-back guarantee
Great edge support, responsiveness, and pressure relief
Quality customer support
Limited model choice
Who Is Onebed Best For?
Onebed is best for picky sleepers who love memory foam. If you love the contouring hug of foam but worry about it being too soft, Onebed lets you unzip the top and rearrange the layers (Firm, Medium, or Soft) instantly.
Why Is Onebed a Better Alternative to Standard Memory Foam?
It solves the problem of "Getting Stuck."
Traditional memory foam can feel like quicksand. Onebed uses a layer of latex on top of the memory foam, giving you that "bounce" and cooling factor so you can turn over easily, while still getting the pressure relief of foam underneath.
What Are The Key Features?
- Adjustable Layers: Swap the order of foam layers to change the feel.
- Davina Latex: Naturally cooling and responsive.
- 15-Year Warranty: Long-term protection for your investment.
- Zero Partner Disturbance: Excellent motion isolation.
What's the Boxing Day Deal?
Onebed has a massive offer: Up to 60% off plus an EXTRA 20% off with code BFSALE20.
6. Sleep Republic – Best Premium Spring Deal
Sleep Republic ignores the "all-foam" trend to build a serious, spring-heavy mattress for traditionalists.
More details
Hybrid build for balanced comfort
Cooling gel-infused memory foam
Great for couples – minimal motion transfer
Strong edge support
15-year warranty and free trial
Only one firmness option
No luxury adjustable bases offered
Who Is Sleep Republic Best For?
Sleep Republic is best for edge-sleepers and those who need firm support. If you sit on the edge of your bed to put shoes on, or hate the feeling of "rolling out," their reinforced edge support is the best in the box.
Why Is Sleep Republic a Better Alternative to Generic "Bed-in-a-Box" Brands?
It solves the problem of "Sagging Edges."
Most boxed mattresses rely heavily on foam, which can feel weak at the edges. Sleep Republic uses high-definition pocket springs (up to 2,250 of them!) and steel perimeter reinforcement, giving you a sturdy, traditional mattress feel that arrives in a convenient box.
What Are The Key Features?
- High-Definition Pocket Springs: Twice the spring count of standard mattresses.
- Cashmere Cover: Luxurious, soft, and breathable.
- Gel Memory Foam: Just enough foam for comfort without the "sink."
- Strong Edge Support: Steel springs reinforce the perimeter.
What's the Boxing Day Deal?
Sleep Republic is offering a rare 25% off sitewide for their Boxing Day sale.

Frequently Asked Questions
Q. Do I really need a promo code for these deals?
A. For Origin (TOP5-5%OFF), Emma (Top5Mattresses10), and Onebed (BFSALE20), yes. The public prices on their sites are higher than what you get with our codes. For Newentor, Sleeping Duck, and Sleep Republic, the discount is automatic or bundle-based.
Q. Is Boxing Day cheaper than January sales?
A. Typically, yes. Boxing Day is the "clearance" event for the year. January "Back to Work" sales often revert to standard discounts (15-20%). If you see a deal over 40% off now (like Newentor, Origin, or Onebed), take it.
Q. How fast is delivery during the holidays?
A. Most brands resume shipping on December 27th. Metro areas (Sydney, Melbourne, Brisbane) usually see delivery within 1-4 business days. Regional areas may take longer due to holiday courier loads.
