- Sleeping Duck

- Noa Lite Mattress
- Dusk&Dawn Essential (Firm)
- Sleep Firm Mattress
We’ve done a deep dive into the features of each of these mattresses to make sure they are the best of the best on the Australian mattress market. From materials to cushioning, to size, trial periods and warranty period, here’s why these 8 mattresses have made the list.
1. Ecosa – $920 (Queen RRP $1,150)
Ecosa is one of the best firm mattresses on the Aussie market, largely due to its high density firm foam and its customisable design, meaning no matter what kind of mattress firmness you prefer, the Ecosa mattress can accommodate.
Ecosa lets you adjust the firmness level for the perfect fit – you can choose from a medium, medium-firm, or firm setting by simply switching the layers. While this is a common feature in innerspring hybrid mattresses, it’s rare in an all-foam design.
The standard Ecosa mattress comes with a medium pressure option, which is how all Ecosa mattresses are shipped. It’s easier to get a firmer mattress by swapping the layers or flipping the mattress.
The medium version, as you can imagine, is the softest of all three settings, but it still feels relatively firm, but at the same time allows your body to comfortably sink into it. The firm layer of the Ecosa we’d rate an 8 out of 10, with 1 being the softest mattress in the world at 10 being the firmest.
Ecosa mattresses work for most sleepers, but typically back and side sleepers will enjoy it the most as the foam supports the natural curve of the body, with a comfort layer offering cushioning for pressure points. It also offers excellent edge support for even more support while sleeping. And, with a 100 night trial and 15 year warranty there’s no reason you shouldn’t give Ecosa a go.
Sleeping Duck – $1649 (Queen)
We highly rate Sleeping Duck as one of the best firm mattresses because it’s one of the only mattresses where you can customise it to create a super firm mattress. While Sleeping Duck wouldn’t be classified as a budget mattress by any means, it certainly makes up for the bigger price tag in features, comfort and customisation.
Featuring a customisable, modular foam layer that can adjusted in 12 separate areas (6 on each side of the bed), the Sleeping Duck mattress goes above and beyond in its customisation capabilities – from whether you want a medium or firm overall, with a soft, medium or extra-firm micro-setting. What’s even better is that you can have a different level of firmness to your sleeping partner, which is a truly unique feature of the Sleeping Duck.
Thanks to its personalised firmness features, the Sleeping Duck mattress is good for all sleeping positions. Side sleepers will enjoy good spring support and cushioned top layer, while back sleepers can choose a firmer top layer to keep their spines aligned. Meanwhile, stomach sleepers will enjoy the gel-infused memory foam layer which relieves pressure on the sore spots.
Koala Soul Mate – Queen $2,899.00
The Koala Soul Mate is a deluxe memory foam mattress, and while it has a pretty big price-tag, for all it delivers, it’s certainly worth it if budget isn’t a concern for you. A plush mattress from the outside yet is also quite firm, this mattress packs a punch in all the right areas.
The Koala Soul Mate mattress comes in two firmness levels: medium-firm (how it’s shipped), and firm. You can switch between these two levels of firmness by flipping the mattress.
I’d say the medium-firm is about a 7/10 on the mattress firmness scale, while the firm side is about a 7.5/10. In all honesty, the difference between the two firmness settings is pretty negligible.
With excellent lumbar support to back and stomach sleepers, the firm setting offers great spinal support, preventing any body aches or back pains. Koala’s Soul Mate mattress, as with all Koala mattresses, has Zero Disturbance technology which stops motion transfer and reduces partner disturbance while sleeping.
Ergoflex – $669.33 (Queen RRP $999)
The Ergoflex 5G is one of the original mattress in box companies. And, it’s one of the highest-quality memory foam mattresses on the market, and arguably the most comfortable. A typical memory foam mattress is designed to adapt to your unique body comforts, offering a well-supported spine and better posture. Not many memory foam mattresses truly offer all these features – except the Ergoflex 5G that is made from high-density foam.
The Ergoflex 5G mattress is medium-firm (although more on the firmer side – roughly a 7/10). However, as you lay on the mattress, you’ll begin to feel yourself sink into the mattress – but not uncomfortably so. It’s more like the feeling of the mattress hugging you.
Similar products in the market typically use memory foam blends, which are low-density. Not to mention the memory foam layer on the Ergoflex 5G is 9cm thick, which is almost twice as thick as many competitors, which is why it’s earned itself a place on our list of best firm mattresses in Australia.
5.Noa Lite Mattress – $774 (Queen RRP: $1199)
The Noa Lite Mattress, the entry level model in Noa’s mattress range, is a very good firm mattress and excellent value for money. With a comfort layer made from Tencel fabric, memory foam, and an adaptive foam, the Noa Lite Mattress has a pocket spring system that feels responsive and will accommodate most sleepers. Designed to provide good comfort and durable support, the Noa offers a firm support level of 7 on a scale of 10. It’s universally comfortable with a subtle hint of plushness, this mattress is suitable for all sleeping positions and body types.
Dusk&Dawn Essential (Firm) – $1,499.00 (Queen RRP: $1,749.00)
The Dusk&Dawn Essential (Firm) is an incredibly firm and supportive mattress and forms the mid range model in the Dusk&Dawn range, which also includes the entry mid-range Premiere and the flagship Signature.
When you order the mattress, you can choose your firmness level with plush (Firmness scale 3-4), Comfy Medium (Firmness scale 5-6) and Firm Support (Firmness scale 7-8).
The Dusk&Dawn Essential (Firm) has a nice topper comfort layer that includes a ‘Comfort-Stretch Premium Fabric’, a Dusk-Air Tech layer, an ‘Eco-Air’ comfort layer, as well as premium comfort foams. The Essential mattress also comes equipped with all the features to ensure a great night’s sleep. Its multi-zoned Iso-Coil pocket coil system features individually encased coils ensuring minimal partner disturbance whilst providing excellent lower back support.
Peacelily – Queen $1,599
A sustainable, eco-friendly flippable all-latex mattress in a box, the Peacelily seems to tick all the boxes. Made with 100% natural and organic materials, the Peacelily is hypoallergenic, cooling and incredibly durable.
Made from non-toxic products handmade from natural latex and certified organic cotton, and pure kapok, the Peacelily contains no polyurethane foams, memory foams, chemical flame retardants, or harmful chemical adhesives.
The natural latex mattress features 100% natural latex rubber, GOTS certified 100% organic cotton fabric and wadding, and adjustable firmness (medium or firm) when you flip the mattress.
And, considering the premium materials used, the Peacelily is quite affordable too, with a Queen mattress priced at $1,599.
Sleep Firm Mattress – Queen $1,299
Marketed as the first “Retail Store Mattress” that comes in a box, the Sleep Firm Mattress is designed specifically for leepers who prefer a firm support and comfort layer. As the name suggests, it has a very clear firm feel, perfect for sleepers who don’t want to feel like they’re sinking into the mattress.
The Sleep Firm Mattress uses an advanced ‘S+Pro’ 5 zone pocket spring system which has a spring count of 1,092 (queen size). This is quite above average for a pocket spring mattress,with this high spring offering great back support and reduced partner disturbance.
Meanwhile, to ensure a firm supportive edge to encase the S+ Pro Spring and to prevent any roll-off, Sleep Firm uses Boomerang Foam technology to create a foam box edge around the full perimeter of the mattress. A foam box technique is something you would find in a traditional retail store pocket spring mattress
Firm Mattress Buying Considerations & FAQs
How firm is a ‘firm mattress’?
How a mattress feels is very subjective and depends on what an individual sleeper’s perception of “firm” is. We rate anything from 7-10 out of 10 as firm. How do we rate firmness? We’ve tested countless mattresses, both online mattresses and in-store mattresses and have a pretty good gauge of the firmness scale.
Firm Mattresses and Back Support
Is a firm mattress better for back support? In most cases, soft mattresses see the body sinking into the thicker comfort layers, which means the spine will not be aligned or supported properly. A firm mattress, however, usually has thick comfort materials like memory foam or latex to keep your back supported and not sinking into the mattress, while also keeping your spine aligned.
How Firm Should a Mattress for a Bad Back Be?
Everyone has different needs when it comes to finding the perfect mattress, but there are some important things to consider when choosing a mattress that will support a bad back.
Medium/medium-firm: Medium/medium-firm mattresses are the most universally enjoyed mattress and typically ideal for most sleepers regardless of weight and sleeping position. They’re firm enough to support the spine without making painful curves, while also offering a nice “hugging” feel and pressure relief.
Firm: Firm mattresses make you feel like you’re floating on top, often offering little to no cradling. Firm mattresses are usually made from dense foam or thicker coil layers, meaning they can withstand more weight. This makes them ideal for heavier sleepers. Meanwhile, a firm mattress can help support the natural curve of your spine, no matter what position you sleep in.
What Bed Base Goes Best with a Firm Mattress?
The type of bed base that you buy depends on several factors including budget, room, if you need storage space, and the type of mattress you have. Bed bases can range from $200 all the way up to the thousands for a Queen size.
The best bed base for a firm mattress will be a bed base that either doesn’t have slats, or a base with slats that are close together to prevent the mattress dipping through the slats.
