Australia's best 'Back Care' mattress 2023

‘Sore back’, ‘bad back’ is a common problem faced by many Australians. Lack of exercise, too much exercise, sport or strenuous work conditions can all create muscle and joint soreness which can affect the quality of our sleep.

So, what is the best mattress for a sore back? In 2023, Bedbuyer Australia rated the Silentnight Onyx Mattress as Australia’s ‘Best Back Care’ Mattress.

The Silentnight Onyx is Australian made and is a true leader in the retail mattress market. It immediately gives out a strong sense of refinement and aesthetic appeal. Even before lying on it, this mattress has a distinct presence and gives out a modern, edgy vibe.

Mattress construction

The top comfort layer of this mattress is highly sophisticated and is a strong indicator of its level of craftsmanship.

This comfort layer contains an exclusive ‘ICE-TEK’ cooling knit which is a revolutionary, thermo-regulating material. It instantly removes heat from your body, helping to maintain a cool, comfortable sleep temperature. In addition, the top layer contains a premium silk cashmere blend which produces a strong yet luxurious feel.

The top cover of the Silentnight Onyx sits over a combination of premium comfort foam and memory foam which offers exceptional comfort and pressure relief. Comfort Sleep have also added a special ‘open cell layer’ to further assist with ventilation and airflow.

The Silentnight Onyx has excellent edge support, thanks to its Edge Boost™ Foam Boxed Wall – an ultra firm, highly resilient foam box encasement which provides the most robust of mattress perimeters.

The Silentnight Onyx is also well-certified as non-toxic and eco-friendly, holding the GECA (Good Environmental Choice Australia) certification.

The Silentnight Onyx possesses an outstanding pocket spring system, namely its 10 Zone Silentpocket™ Dual Coil System. This spring unit contains a high spring count with approximately 1,740 springs (queen size). As you would expect, it offers excellent spinal support and minimal partner disturbance. It can accommodate people of all sizes with little fuss.

The Silentnight Onyx also offers incredible value considering the high quality construction and its delightful balance of comfort and support. The mattress comes with a 10-year warranty, and we would definitely recommend it for those who struggle with sleep temperature during sleep.

Firmness options

The Silentnight Onyx is available in firm, medium and plush versions.

The firm version should suit most ‘back sleepers’, whereas the medium and plush versions should suit all sleeping positions. However, this suitability will vary between individuals.

All firmness versions of the Silentnight Onyx respond well to normal sleep movements, which means that changing sleep positions (and intimate activities) shouldn’t be any trouble.

Preferred firmness levels will vary between individuals. It’s worth noting also that innerspring mattresses are generally more responsive than foam mattresses.

What bed base should I use?

As with most mattresses, we recommend the Silentnight Onyx to be used with a solid bed frame or a solid ensemble base (with the slats no longer than 8 cm apart).

It’s worth noting here that mattress firmness, performance, and durability will vary with different bed bases.

Available sizes

The Silentnight Onyx is available in all 7 mattress sizes (super king, king, queen, double, king single, long single, and single) so it will accommodate all adult sleeping situations.
