Koala vs Koala Calm As Mattress Comparison

The Koala mattress will suit side sleepers well (in fact, it’s our pick for the best mattress for side sleepers) because it provides great alignment for side sleepers’ necks and spines. As a side sleeper, Elese loves the supportive softness that’s good for pressure relief. It’s also good at minimising partner disturbance as the foam absorbs pressure well, making it ideal for co-sleepers.

We reckon side sleepers will get a great night’s sleep on the Koala Calm As mattress. With its 5 layers and foam construction, it offers a lot of soft, sinkable support for side sleepers’ necks and spines, helping to keep them in the correct alignment. The Original Koala mattress (the precursor to the Koala mattress) impressed Cosier writer Elese with its minimal partner disturbance and the Calm As mattress, with 2 extra layers, will be even more effective. Co-sleepers, this one’s for you.

We rate the Koala mattress better than good - we rate it great. This foam mattress is dreamily soft yet supportive and breathable. We love that it’s really effective at minimising partner disturbance. Koala itself has a top-notch approach to environmental sustainability which is a big tick for us. Oh, and it comes with a little Koala toy. What’s not to love?

• The soft and cosy feel.
• Less deep than other mattresses in a box, so fitted sheets fit easily.
• Customisable firmness level that can be flipped. 
• Koala’s commitment to doing good for the planet, people and animals.

• No handles which makes turning and moving it pretty difficult.
• A little hot during Aussie nights, especially in comparison to the Eva mattress which Elese has also tested.

We reckon so. Designed to suit a range of sleepers, but especially good for side sleepers, the Koala Calm As foam mattress is great at providing supportive comfort all night long. It suits Aussie sleepers well, thanks to the attention paid to keeping you cool as you sleep. Partner disturbance is also minimal. Koala itself is a great Aussie company with some really solid eco-credentials.

• The supportive comfortable feel of the mattress.
• Customisable firmness level that can be flipped.
• The attention paid to keeping you cool on hot nights.
• Koala’s environmental and sustainability focus.

• It’s pretty deep at 29cm so check if your fitted sheets will work.
• No handles which makes turning and moving it tricky.
• It’s heavy, weighing up to 51.75kg for the king - those handles really would have come in handy.

The Koala mattress is a foam mattress that boasts 3 layers:

1. A 7cm comfort layer topped with a breathable Tencel Lyocell fabric that’s 35% Tencell Lyocell and 65% polyester.
2. A customisable firmness layer that can be flipped. One side is medium-firm, the other side firm. You can change the firmness by unzipping the mattress and flipping this layer.
3. The final support layer that has 3 different support zones to cradle every inch of your weary body and prevent your hips sinking too low.

All the foam is polyurethane foam that’s certified free of formaldehyde and other nasties and is low-VOC (volatile organic compounds).

1. A 7cm polyester sleeping surface and a 1cm quilted cover. This sleeping surface is designed to keep you cool and dry as you sleep.
2. Flippable comfort layer which offers you a medium-firm or firm feel.
3. A support layer with 3 support zones that are targeted to your important bits, like your back and shoulders. It’s got air tunnels too to help air move freely and avoid that sticky feeling. It’s also designed to spread your weight evenly across the mattress.
4. Another support layer, much deeper this time. It’s the firmest core of the mattress and should provide great support for every type of sleeper.
5. Edge support to make sure you don’t sink when you perch on the end to put your socks on.

The Koala Calm As mattress has an industry standard warranty of 10 years that covers any physical damage and defects in the materials and workmanship. It doesn’t cover normal wear and tear, which includes ‘softening of the product that does not affect performance’. This sounds a little subjective to us as your idea of your mattress becoming too soft they might argue isn’t performance related.
