the Sleep Firm mattress
Become a firm believer in better sleep
Think you’ve had the best sleep of your life? That sounds like a challenge. If you prefer a firm feel to your mattress, you’ve come to the right place.
At Sleep Firm, we do one thing. Make firm mattresses. There’s no room for anything else—especially softness. We’d love to show you why we make the best firm mattress in Australia.
Welcome to Best Firm Mattress Australia
It’s great to have you. At Sleep Firm, we have a single-minded focus – giving the people firmness. We make entirely firm mattresses, from the centre to the firm supportive edge.
Other mattress brands might have a soft mattress and a slightly firmer pocket spring mattress in their range. Not us. We are firm to the core.
Just How firm is our firm mattress?
We’re glad you asked. Let’s put it this way – it’s very firm but not rock hard. We like to define it as enjoyably firm. An enjoyably firm mattress is a mattress that provides a supportive and comfortable sleeping surface while still offering a significant level of firmness. It should have enough resistance to support the natural curves of your body and prevent excessive sinking or sagging, especially around the hips and lower back.

How We Create Firmness
Straight out firm support doesn’t come out of thin air. Our firm mattress has been meticulously engineered to embody the very essence of firmness.
High spring count
Our 5 Zone S+Pro high spring count mattresses promote the best support for all body types and weights. You won’t find this in a major retail store mattress.
Boomerang foam
Our Boomerang Foam technology is a premium density foam that springs back into place, night after night. Its open cell structure will also keep your sleep environment cool.
5 sleeping zones
Each zone is designed to provide targeted support to different parts of the body, with the goal of promoting proper spinal alignment and reducing pressure points.
Foam box
edge
Our quality foam box edge helps prevent roll off. You can rest assured that your firm mattress will continue to provide a high level of sleep quality from edge to edge.
