Sleep Firm Ultra Mattress
The Sleep Firm Ultra Mattress is one of Australia’s firmest mattresses in a box, offering exceptional support, strong responsiveness, and reliable build quality.
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. The Sleep Firm Mattress is Australia’s premier, firm mattress.
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.
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.
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.
