How big is a super king mattress?
A standard, super king mattress is 203 cm wide and 203 cm long. It is the largest mattress size available (in Australia) and provides an abundance of sleeping space.

If you are considering a super king mattress, here are some important things that you need to know before taking the plunge!
Why are super king mattresses hard to find?
According to a recent Bedbuyer survey, only about 1% of Australians sleep on a super king mattress. When you consider that 21% of Aussies sleep on a king mattress and 61% on a queen, it’s easy to see why it isn’t economically feasible for many mattress companies to manufacture super king mattresses.
Super king mattresses are rare in the online mattress market, with only several companies (e.g. Sleep Republic) offering this size. If you’re looking in-store at a major retailer, a super king mattress will usually involve a special order that may take weeks to arrive.
Super king mattresses and partner disturbance
It’s worth mentioning that larger size mattresses (e.g. king size) will have less partner disturbance than a smaller size mattress (e.g. double size). This is simply because movement has further to travel (on a larger size mattress) and so disruption to your sleeping partner is less.
Not surprisingly, minimising partner disturbance is critical to sleep health and sleep quality. A mattress that reduces the effects of a restless partner is something to consider, and a super king mattress will most certainly help to minimise motion transfer.
What bed base should I use with a super king mattress?
Like super king mattresses, super king bed bases are not particularly common.
As with most mattresses, we recommend super king mattresses to be placed on a solid bed frame with fixed slats (not flexible/posture slats). These slats should ideally be no more than 8cm apart, to ensure that the mattress is supported correctly.
Dusk&Dawn Liquorice Bedhead & Base
As is the case with many king size bed bases, super king bed bases often come in two pieces (such as the Dusk&Dawn Liquorice Bedhead & Base pictured above). This is so that each piece can fit through doorways and stairwells. The two middle edges can also add extra support in the middle of the bed.
Other super king bed bases may require the product to be assembled. This removes the need for ‘two halves’ as the base will come in ‘IKEA style’ boxes and flat packs.
This is the case with the the Ecosa Zen Bed Base (pictured below) which uses incredibly strong American Ash timber.
As super king beds are of considerable size, we always recommend that you measure your space carefully to ensure that a super king bed will fit nicely into your bedroom.
So there you have it! We hope that our list of Australia’s best super king mattresses assists you in your selection process. If you have any questions about purchasing a mattress, please leave a comment below. Our team is standing by!
