Australian Double size mattress
At 139cm wide and 190cm long, the Double mattress size is a great option for Australians of all ages. It is often an ideal choice for teenagers growing out of Single sizes.
A Double bed can sleep two adults, and is a versatile option for guest bedrooms. Similar sizes include the longer and slightly wider Queen, or the substantially larger King size mattress.

Why choose a Double?
A Double bed can accommodate 1 to 2 adults. It is a popular choice for couples with smaller bedrooms or limited sleeping space, and is a great solution for guest rooms.
This size offers ample space for single sleepers, and is especially ideal for teenagers who desire more room to stretch out. Taller individuals may prefer a Queen for the added length of 130mm, but otherwise, the Double is a great choice.
As with all mattress sizes, it is important to take into account your personal comfort in a shared resting space. Many couples and individuals prefer a Double mattress, while others choose a larger sleep surface. If you are unsure if a Double is the right size for you, we suggest using our online Mattress Selector or trying a Sealy Double size in-store.

Choosing a Double size bed
Who is it best for?
A Double bed is ideally suited to 1 adult, or 2 adults with a small bedroom.
This size may also be ideal for teenagers outgrowing the width of a Single mattress. Taller teenagers and adults may prefer the additional length of a Queen, however. The Double is best for individuals whose height is 5′9″ or 175cm and under.
Ideal bedroom size
Double mattresses tend to fit best in small or medium-sized bedrooms. This is typically a room of 3-4 metres in length and width, or approximately 10-13ft.
Ensure your Double mattress will fit comfortably in its intended space. Start by measuring the distance from one wall to the other to determine the room’s length and width, and check whether there will be plenty of clearance to open doors, reach closets, and walk around the bed comfortably without feeling restricted.
Best comfort level
Sealy Double size mattresses are available in a range of comfort options from Ultra Firm to Ultra Plush. The right comfort level for you depends on your sleep position and general sleep preferences. Read more on comfort choices or get started with our Mattress Selector for tailored suggestions.
