The measurement of a double size mattress in Australia is 137 cm wide by 187 cm long. In simple terms, it’s slightly larger than a single mattress but smaller than a queen, making it a popular choice for teenagers, guest bedrooms, and smaller master bedrooms.
Here’s why Australians love double size mattresses: they provide enough space for one sleeper or a snug fit for two, without taking up as much room as a queen. Knowing the exact measurements ensures your bedding, bed frames, and bedroom layout are all compatible.
Double size mattresses come in several types and styles to suit comfort preferences and room aesthetics. Australian shoppers often choose from:
Features traditional coil springs
Offers firm support with bounce
Ideal for back or combination sleepers
Contours to the body for pressure relief
Reduces motion transfer, perfect for couples sharing a smaller bed
Retains shape and provides a modern feel
Combines innerspring coils with memory foam or latex layers
Offers balanced support and comfort
Popular for Australian households wanting both firmness and softness
Made from natural or synthetic latex
Hypoallergenic, durable, and resilient
Medium-firm support with responsive bounce
Extra cushioning sewn into the top layer
Enhances comfort for side sleepers or those seeking plush softness
The main reason Australians choose double size mattresses is their versatility, fitting well in medium bedrooms while still offering comfortable sleeping space.
Selecting the right double size mattress involves considering room dimensions, sleeping preferences, and lifestyle needs. Here’s a practical guide:
Double mattress: 137 cm x 187 cm
Ensure space for bedside tables, storage, and free movement
