In simple terms, a mattress double is a mattress size designed to comfortably accommodate one adult sleeper or provide a compact shared sleeping surface for two people. In Australia, a double mattress typically measures 138 cm wide x 188 cm long, making it larger than a single or king single, but smaller than a queen.
The main reason Australians choose a mattress double is balance. It offers more space than single options without requiring the room size or budget of a queen mattress.
Here’s why mattress double remains a popular choice across Australia:
Ideal for solo sleepers who want extra room
Suitable for teenagers and young adults
Fits smaller bedrooms and apartments
More affordable than queen or king sizes
Easier to move, rotate, and transport
In essence, a mattress double delivers comfort and practicality without excess.
Understanding size helps ensure the right fit.
Standard Australian Mattress Double Size:
Width: 138 cm
Length: 188 cm
Compared to other sizes:
Wider than a king single (107 cm)
Narrower than a queen (153 cm)
Shorter than king and queen lengths
Here’s why this matters: mattress double suits average-height sleepers but may feel short for taller adults.
