Are firm mattresses better for your back?
A common misconception is that firmer mattresses always provide better back support. While this can be true in some cases, the reality is more nuanced.
A firm mattress generally keeps the body in a flatter sleeping position and reduces excessive sinking through the hips and lower back. For many back sleepers, this can help promote healthy spinal alignment and improve overall support.
However, firmness alone does not determine whether a mattress is supportive. The quality of the support system, comfort materials, body weight, and sleeping position all play an important role.
Many of the mattresses on this list use advanced pocket spring systems that provide excellent spinal support while still offering enough comfort to relieve pressure points.
Who should buy a firm mattress?
Firm mattresses are often best suited to back sleepers, larger individuals, and those who simply prefer a more supportive sleeping surface.
People weighing over 100kg frequently benefit from a firmer mattress because it can better resist excessive sinking and maintain spinal alignment throughout the night.
Firm mattresses are also popular amongst sleepers who dislike the sensation of being “hugged” by thick comfort layers. Instead, they provide a more stable and supportive feel that many people find easier to move around on.
That said, some side sleepers may find very firm mattresses uncomfortable, particularly around the shoulders and hips. In these situations, a medium-firm mattress may be a more suitable option.
Firm vs extra-firm mattresses
Not all firm mattresses feel the same.
On Bedbuyer’s firmness scale, most mattresses classified as “firm” fall between 7.5 and 8.5 out of 10. These mattresses generally provide strong support whilst still offering a reasonable level of comfort and pressure relief.
Extra-firm mattresses typically rate 9 out of 10 or higher. These mattresses have very little sinkage and can feel noticeably harder beneath the body.
Examples of extra-firm mattresses on this list include the Sleep Firm Ultra and the Ecosa Align Firm. These mattresses are designed specifically for sleepers who genuinely prefer an exceptionally firm feel.
For many Australians, a traditional firm mattress offers a better balance between comfort and support than an extra-firm model.
Another benefit of firm mattresses is that they often sleep cooler than softer mattresses. This is because firm mattresses typically contain thinner comfort layers, allowing less body sinkage and reducing the amount of heat trapped around the sleeper.
