Single mattress size
Australian Single size mattress
At 91.5cm wide and 190cm long, an Australian Single size mattress is suitable for children and solo sleepers of all ages. We have a Single mattress in every range to meet all budgets and lifestyle needs.
The Single mattress is the smallest standard size in Australia. The closest options are the longer Single XL and King Single beds, or the wider Double size mattress.

Why choose a Single?
Traditionally, Single mattress sizes have been a common option for children as they transition from a cot to a bed. However, single sleepers of all ages may enjoy the space-saving convenience and comfort of a Single.
The narrow size makes this option popular for small bedrooms and limited guest sleeping spaces. If the bed is intended for a particularly tall individual, you may wish to consider the longer Single XL or King Single sizes.
Otherwise, if you are looking for more room to stretch out, a Double mattress is the same length as a standard Single but much wider. It is also able to accommodate two people.

Single mattress
Sealy’s single mattresses are a great choice for children of all ages, and even adults. Sealy’s Single mattresses are 915mm wide and 1900mm (nearly two metres) long so they make a great first bed, but still give adults enough room to move around. One person sleeping in a Single bed has as much room as two people in a King size bed. Single beds are also great space savers, with the dimensions of a single bed fitting into any bedroom.

Single XL
Children grow fast and Sealy’s super-sized Single XL is a popular choice for parents who want to get the most out of their Sealy mattress’s ten year life span. The Sealy Single XL is the same width as a Single but 2030mm (more than two metres!) long. The long single bed provides extra room to stretch out without taking up too much precious bedroom space. Sealy’s Single XLs are a great idea for holiday homes and guest rooms: put two of them together and you have a King size bed or split them to comfortably accommodate extra adults and children.

King Single mattresses have both extra width (1055mm compared to 915mm for regular Singles) and length (2030mm), making them a great option for older children, rapidly growing teenagers and taller adults who want more space but don’t have room for a Double or Queen size bed. Families are increasingly choosing to invest in Sealy’s durable King Single size mattress right from the beginning to save the hassle of changing beds as children grow.
While you’ll appreciate the noticeably greater sleep space, Sealy’s King Singles don’t take up too much extra room. They fit neatly into most bedrooms and are effective space savers in apartments.

Queen mattress
There’s a good reason why Sealy’s Queen size mattresses are so popular. They are the perfect size for couples – 1,525mm wide and 2,030mm long – so you can stretch out and be comfortable, whilst still easily fitting into most bedrooms.
Sealy’s Queen size mattresses deliver year-round comfort and practicality. Cosy in winter and with enough personal space in summer, the Queen size mattress is only 300mm narrower than a King – in fact, many couples prefer to use a King size doona over their Queen size bed for extra luxury.

King size mattress
Sealy’s King size mattress dimensions are 1835mm x 2030mm, making it perfect for those who like a little more space.
While it is the same length as a Queen, the King size mattress delivers an extra 30cm in width, which means it’s large enough to provide a night of disturbance-free sleep – especially if you have young ones visiting your bed.
If you’ve got a bedroom with enough space to accommodate a king bed this size, there’s nothing like a Sealy King. The mattress sits on two separate bases which means you can get in and out of bed with less partner disturbance, making king beds ideal for shift workers, early risers and restless sleepers.

Sealy’s Super Kings are becoming a popular choice for busy couples who need to be able to sleep well every night and wake refreshed to meet the day’s challenges. If you’ve got a bedroom with enough space to accommodate this size, a Sealy Super King bed is the ultimate sleeping experience.
