AUSTRALIA-WIDE SHIPPING
A king size mattress refers to a mattress that measures significantly wider and longer than smaller bed sizes, providing extra space for adults to sleep comfortably. In Australia, a standard king size mattress typically measures 183 cm wide by 203 cm long. King mattresses are ideal for couples, families who co-sleep with children, or anyone who wants luxurious personal space during sleep. They can accommodate a wide variety of bases and frames, including adjustable beds, platform beds, and upholstered bed frames.

How to Choose a King Size Mattress
Selecting the right king mattress requires thinking about size, support, comfort, and lifestyle.
1. Measure Your Bedroom
Ensure your room can comfortably accommodate the mattress and allow for movement around the bed. Standard king mattresses need at least 3 meters of room width and sufficient length.
2. Determine Mattress Firmness
-
Soft: Great for side sleepers and pressure relief
-
Medium: Balanced comfort for combination sleepers
-
Firm: Ideal for back and stomach sleepers or heavier individuals
3. Check Material & Construction
-
Memory foam for contouring comfort
-
Pocket-spring for bounce and support
-
Hybrid for a combination of support and plushness
4. Sleep Position & Partner Preferences
Consider your sleeping style and whether your partner prefers a different firmness level. Adjustable or split king options can solve conflicts.
5. Test for Comfort
If possible, try before you buy: lie on the mattress for 10–15 minutes in your usual sleeping position to gauge comfort and support.
6. Factor in Accessories
-
King sheets, mattress protectors, and bed frames must match the mattress dimensions
-
Adjustable bases or bed frames should be compatible
In simple terms: choose a king mattress that suits your space, sleep style, and personal comfort preferences for long-term satisfaction.
