3. The Koala Soul Mate Mattress


The Koala Soul Mate Mattress is a high-quality mattress available in the Australian market. It has an open-cell foam layer that prevents squishing or sinking of the mattress under your weight while you lay on it. This foam layer design makes the mattress for all sleeping positions without causing any backaches the following morning. It is ultra-resilient and offers excellent spinal support while you're asleep.  

Moreover, this mattress-in-a-box ranks on the firmer side, offering excellent lumbar support to back and stomach sleepers. The firmness is ideal for strong spinal support, preventing any body aches or back pains. Plus, as a firmer mattress, it also helps to distribute body pressure and ensure better pressure relief optimally. It also has a Zero Disturbance technology that prevents motion transfer and allows no partner disturbance while sleeping. 


This Koala Mattress ranks a bit higher on the firmness scale compared to other hybrid or memory foam mattresses, which can cause some discomfort for side sleepers.


As one of the best-known mattress brands in Australia, you can always trust the Koala mattresses for their superior quality and comfort that ensures a good night's sleep. The firmness and open-cell foam layer of the Soul Mate mattress make it a great choice for offering you a comfortable and ache-free sleeping experience.

4. Peace lily Latex Mattress


The all-latex Peace lily mattress is a medium-firm mattress with one side that's medium while the other side is firm. The medium side is more comfortable for light sleepers and side sleepers. But, if you're a back or stomach sleeper, the firm side might be a better option as it offers superior spinal support. Both these sides provide excellent cushioning to your body to prevent body aches while you're sleeping. 

The medium mattress side has a firmness of five, while the firm mattress side shows a firmness of seven, that's ideal for offering a comfortable sleeping environment. Moreover, this mattress is not like a regular innerspring mattress and feels quite different because you don't get any sinking feeling with this all-natural latex mattress. Instead, you'll feel like almost floating on the mattress top as it keeps your body elevated. 


The Peacelily latex mattresses are quite springy compared to high-density foam mattresses or hybrid mattresses, so you might not get the sinking or hugging feeling of those mattresses. 


The Peace lily pure latex mattress is one of the best natural mattresses in Australia, known for its superb lumbar support and excellent whole body pressure relief. So, if you're looking for a mattress that ranks high on the firmness scale without causing any cradling feeling, this natural latex mattress can be your best pick.

5. Dusk & Dawn Signature Mattress

It can retain its shape and firmness for a long time, so you need not worry about the mattress sagging any time soon. Also, its five-zone pocket springs offer excellent body contouring and help in relieving pain and stress from the pressure points of your body.

These pocket coils also minimise partner disturbance while you're sleeping. So, even if your partner has a habit of tossing and turning, it won't affect your sleep. Also, the Eco-Air technology offers optimal temperature regulation and creates a cool sleeping environment for hot sleepers. 


Dusk & Dawn's Signature Mattress is a high-end sleeping mattress, so it might be a little out of budget for most customers looking for an affordable mattress.

Now that you know a little more about the best mattresses that are on the firmer side, it's time to look into some frequently asked questions about mattresses. 

So, in this section, we've answered some of the most commonly asked questions regarding different mattresses and their firmness. Let's take a look! 

1. Are Hybrid Sleeping Mattresses Firmer Than Normal Mattresses?

When it comes to hybrid sleeping mattresses, you usually get a firmer feeling compared to any traditional spring mattress. The multiple, dense foam layers make these mattresses firmer where you get a bouncing feeling instead of the sinking feeling of a normal foam mattress. As hybrid sleeping mattresses are higher on the firmness scale, they offer superior lumbar support.

Generally speaking, most hybrid sleeping mattresses range between medium and firm on the firmness scale to ensure comfort and good spinal support. So, if you have a bad back, a hybrid mattress is your best pick for an ache-free sleep. But, if you want to experience a cradling and hugging feeling while sleeping, normal mattresses might be a better fit for you. 

2. Are Latex Mattresses Firmer Than Coil Mattresses? 

If you compare latex sleeping mattresses like the Peace lily mattress with traditional coil mattresses like the Eva mattress, the former is distinctly firmer. This is because of the natural latex foam that makes them bouncy instead of pillowy. A latex mattress will elevate your body to the surface, so you'll feel like sleeping on the mattress instead of sinking in the mattress. 

Furthermore, as the body remains elevated on a latex mattress, the spinal support is much better compared to the normal sleeping mattresses. It also offers better breathability and airflow to create a comfortable sleeping environment for an ache-free slumber. 

However, the firmness of the latex mattresses can be a bit uncomfortable for side sleepers. So, if you're planning to switch to latex mattresses from normal memory foam mattresses, it might feel a bit different. 

3. How Can Mattress Firmness Create A Cooler Sleeping Environment? 

To create a cooler sleeping environment, it's essential to increase body-to-air contact for better heat dissipation and temperature regulation. Unless you own a cooling gel memory foam mattress, normal memory foam mattresses essentially decrease body-to-air contact because of their sinking and cradling feel. Hence, the sinking feeling becomes suffocating instead of being comfortable. 

But, if your mattress is on the firmer side, it'll elevate your body without the sinking feeling and increase body-to-air contact. It also enhances airflow and breathability while you're sleeping. Thus, the skin surface will come in direct contact with air to regulate your body temperature effectively and create a cool and comfortable sleeping environment, even if you're a hot sleeper. 

4. Do Mattresses Lose Their Firmness Over Time? 

The firmness of a mattress depends on its fabric quality, foam layers, and its pocket springs. While no mattress comes with a lifetime warranty, a high-quality mattress will be able to retain its shape and firmness for a long time without needing frequent replacements. 

As a mattress grows old, its spring coils and foam layers eventually start acting up, and the mattress becomes saggy. So, if you have an old mattress, the sinking feeling will increase every time you try to sleep. 

Usually, it's best to switch a mattress after six months to a year if you prefer to sleep on firm mattresses. But, if you go for a high-end mattress like the Signature Mattress, you can use it for a longer time.
