Up to 2250 pocket springs in a mattress

12 years warranty

More pocket springs for more support

We have been designing, refining, and making mattresses for over 20 years. And what have we discovered? The more springs in a mattress, the more support you receive. That's why we've squeezed as many as 2250 springs into one mattress.

Cloud-like comfort

Cashmere knitted fabric for the ultimate softness.

Increased breathability

Natural latex regulates airflow and body temperature through thousands of ventilation holes.

Dynamic edge support

Higher tensile steel springs along the edges of the mattress protect sleepers from rolling off the bed.

Comfortable contouring

Gel-infused memory foam contours to your body, providing pressure relief.

Sleep-inducing support

Up to 2250 high definition pocket springs provide support in 5 specific body zones and for co-sleepers, you won’t even know your partner is there.

Out of this world circulation

3D spacer fabric (a product which knits different fibres together on different faces) further enhances airflow.

We're the real deal

We've been dreaming up new designs for mattresses for over 20 years. We've refined our mattress design by constantly experimenting and investigating new technologies and materials. We've found a way to create pocket spring-loaded mattresses which can still fit in a box. Our hybrid mattress has been helping people all over Australia snooze soundly at night.



People often focus on foam mattresses, but we know pocket springs are better. They're more supportive and minimise partner disturbance. That's why we've packed as many as 2,250 springs in one mattress, paired with comfortable and luxurious foam layers. Learn more about our signature High Definition pocket spring system here.

How does a hybrid mattress feel?

The Sleep Republic hybrid mattress is medium/firm feel. The best mattress for back pain offers a high level of support – which is exactly what we have designed. The HD Pocket Springs for support, married with the gel infused memory foam and latex pillow top for comfort make quite sure of it. Not too soft, not too hard; the best of both worlds.

100 night free trial

Everyone sleeps differently. If our mattress isn’t the right fit for you, you can return it within 100 nights. No hidden conditions, no added cost, no problem.
