Mattress dimensions and bed sizes refer to the standard measurements of mattresses and the corresponding bed frames, designed to ensure a comfortable fit for one or more sleepers. In simple terms, these sizes help Australians choose the right mattress for bedrooms, guest rooms, and family homes based on space, comfort, and lifestyle.
Here’s why it matters: understanding mattress dimensions is essential for selecting bed frames, bedding, and bedroom layouts that maximise comfort and functionality.
Australian mattress and bed sizes follow nationally recognised dimensions, making it easier to select bedding and furniture.

Measure Your Bedroom
Ensure the mattress fits comfortably with room for bedside tables and movement
Consider the Number of Sleepers
