King Koil Platinum Luxury Serenity Plush Review
The King Koil Platinum Luxury Serenity Plush is a soft, innerspring mattress that also comes in an ultra firm, firm, and medium version.
Purchase and delivery
This mattress can be ordered online through the Forty Winks website. It can also be purchased through any of Forty Winks’ stores across Australia.
Delivery is available Australia-wide but delivery fees (and times) do vary. Online delivery fees are based on your location from the nearest store, and delivery times will depend on stock availability. For more details, see our ‘Delivery’ section below.
Visually, the King Koil Platinum Luxury Serenity Plush presents with a simple but classic style. It uses a grey and white colour theme and its finishings demonstrate a high level of refinement.
Comfort and support
The top comfort layer of this mattress includes a number of materials including AeroQuilt, AeroFoam, Talalay latex, and FlexGel Infused Latex. It also includes a layer of ‘Micro Comfort Coils’ to help with body contouring.
This top layer feels noticeably soft, with a slight sinking feeling. As you would expect, there is an abundance of pressure relief and this may compromise back support.
The mattress should suit most side sleepers, but it may also suit back sleepers and stomach sleepers. Understandably though, this suitability will vary between individuals.
We rated this mattress as a ‘plush’ feel and a 3.5 / 10 on the firmness scale. Please note that our firmness ratings are just a guide and they do not necessarily relate to comfort. Furthermore, our firmness ratings are assigned based on Bedbuyer’s testing process and these may differ from firmness ratings given by individual companies.
The spring system used in the King Koil Platinum Luxury Serenity Plush is a Reflex Platinum Support System. This spring unit feels robust and will accomodate people of all sizes. It offers excellent spinal support assuming that the firmness option chosen is suitable for your body type.
The King Koil Platinum Luxury Serenity Plush responds nicely to normal sleep movements. 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.
The finer details
In terms of build quality and craftsmanship, the King Koil Platinum Luxury Serenity Plush is outstanding. Edge support is good, thanks to its Performa Edge Support. This means that you should be able to use the entire surface of the mattress.
This mattress also isolates motion well, so a restless partner shouldn’t be any problem.
The mattress has a 10-year warranty – a perfect example of A.H. Beard’s confidence in its product.
What bed base should I use?
As with most mattresses, we recommend the King Koil Platinum Luxury Serenity Plush 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.
Sleep Republic Pro Base
Furthermore, we do not recommend the King Koil Platinum Luxury Serenity Plush to be used with an adjustable (electric) bed base. 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 King Koil Platinum Luxury Serenity Plush is available in 7 sizes (super king, king, queen, double, king single, long single and single ) so it should suit all sleeping arrangements.
Here are Australia’s standard bed (mattress) sizes in 2021.
Final verdict
The King Koil Platinum Luxury Serenity Plush is nice mattress with a particularly soft feel. Its quality and craftsmanship is outstanding and it comes with the added security of a 10 year warranty.
