Is a bigger bed always better?
Ultimately, the best bed size hinges on your individual comfort and what you prefer. To sum it up, if your room and wallet allow, opting for a larger bed usually translates to greater comfort, particularly for couples or those who move around a lot in their sleep. Conversely, a smaller bed can be an ideal and perfectly comfortable solution for single individuals in more compact living spaces.

In Australia, the title of the "biggest" standard bed/mattress size typically belongs to the Super King. A standard Australian Super King mattress measures approximately 203 cm wide x 203 cm long (80 inches x 80 inches).
While there are larger, specialty sizes available, the Super King is the largest that is widely recognized and readily available in Australia.
