Each year, we get hundreds of bed shoppers asking what is the Best Cooling Mattress?
Overheating during sleep is a common problem faced by many Australians. Hot and humid climates can create uncomfortable sleep environments, hugely affecting the quality of our sleep.
So what is the best mattress in terms of cooling and temperature regulation? In 2022, our review team gave the nod to the Silent Night Onyx Mattress as Australia’s ‘Best Cooling’ Mattress.
Silent Night Onyx – 2022 Best Cooling Mattress
The Silent Night 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. To see this mattress in ‘real life’, here is our video review:
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 Silent Night 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, another reason for its best cooling mattress award.
Our review team gave the nod to the Silent Night Onyx Mattress as Australia’s ‘Best Cooling’ Mattress.
The Silent Night 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.
All firmness versions of the Silent Night Onyx respond well to normal sleep movements, and we rated its level of responsiveness as ‘optimal’. In basic terms, this means that changing sleep positions (and intimate activities) shouldn’t be any trouble.
Please note that our responsiveness scales are just a guide and preferred responsiveness levels will vary between individuals. It’s worth noting also that innerspring mattresses are generally more responsive than foam mattresses.
Firmness options
The Silent Night Onyx comes in a firm, medium, and plush version. You can see our specific firmness ratings in each review.
It is rather ‘firm’ range overall, with the plush version not as soft as some other plush options. If you are after a softer mattress range the Neoluxe Vantage Silver would be the perfect alternative.
The firm version should suit most back sleepers, whereas the medium and plush versions should suit all sleeping positions. Understandably though, this suitability will vary between individuals.
The finer details
The Silent Night 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.
As our ‘best cooling’ mattress award implies, this mattress has an exceptional ability to maintain a cool sleep temperature. This is relevant for many Australians who have difficulty with ‘sleeping hot’ at night. The Silent Night Onyx is also well-certified as non-toxic and eco-friendly, holding the GECA (Good Environmental Choice Australia) certification.
The Silent Night 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.
What bed base should I use?
As with most mattresses, we recommend the Silent Night Onyx to be used with a solid bed frame (such as the Sleep Republic Pro Base), or a solid ensemble base (with the slats no longer than 8 cm apart).
A bed frame (with flexible slats) may still be adequate, but again, we strongly recommend that the distance between each slat is less than 8 cm. Use of an unsupportive mattress foundation will usually void the mattress warranty.
Furthermore, we do not recommend the Silent Night Onyx to be used with an adjustable (electric) bed base as this will also void the warranty. Here is our full list of mattresses that are compatible with an adjustable bed base.
It’s worth noting here that mattress firmness, performance, and durability will vary with different bed bases.
Available sizes
The Silent Night Onyx is available in all 7 mattress sizes (super king, king, queen, double, king single, long single, and single) so it will accomodate all adult sleeping situations.
Here are Australia’s standard bed (mattress) sizes in 2022.
Summary
The Silent Night Onyx is an outstanding mattress that was awarded Australia’s Best Cooling Mattress in 2022. It contains a cool and comfortable top layer, along with a spring system of the highest quality.

Sleep temperature can be complex with many factors involved. These factors include (but are not limited to) the occupant/s of the bed, room temperature, humidity, seasonal weather changes, type of linen/bedding, type of pillow, and type of mattress. As such, it can be difficult to predict how each person will respond to a specific mattress and/or bedding products. As such, we cannot guarantee that any specific mattress will help hot sleepers.
