Which bed size to choose?

Single Mattress

915mm x 1900mm

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. Singles are also great space savers, fitting into any bedroom.

Not sure if this is your size? Take a look at Sealy’s King Single and Double sizes or use our Mattress Selector to find out which mattress is the right one for you. You can also download our Mattress Guide to help guide you through the process of choosing the right mattress.

Single XL Mattress

915mm x 2030mm

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. It 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 Mattress

1065mm x 2030mm

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 Singles 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.

If you’re thinking about a Sealy King Single, why not take a look at our Double and Queen mattresses as well, or use our Mattress Selector to find out which mattress is the right one for you. You can also download our Mattress Guide to help guide you through the process of choosing the right mattress.

Double Mattress

1385mm x 1900mm

Double mattresses are great space savers and are a versatile option if you’re looking for a guest bed. They are also a popular pick for teenagers as many bedrooms will accommodate a Double bed.

If you’re thinking of a Double, you might also like to look at Sealy’s Queen size mattresses , or use our Mattress Selector to find out which mattress is the right one for you. You can also download our Mattress Guide to help guide you through the process of choosing the right mattress.

Think Sealy’s Double is the right size for you? Visit your local Sealy retailer to experience a Sealy for yourself. It’s a great way to work out which mattress is right for you – and you’ll soon see why so many Australians choose Sealy.

Queen Mattress

1525mm x 2030mm

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.

Cosy in winter and with enough personal space in summer, Queen size mattresses are only 300mm narrower than Kings – in fact, many couples prefer to use a King size doona over their Queen size bed for extra luxury.

Sealy’s Queen size mattresses deliver year-round comfort and practicality. No wonder they are Australia’s favourite mattress brand.

King Mattress

1835mm x 2030mm

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 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 it ideal for shift workers, early risers and restless sleepers.

Super King Mattress

2030mm x 2030mm

Sealy’s Super King size mattress dimensions are 2030mm wide x 2030mm long, offering a deluxe sleeping space for couples who love to stretch out or who have little ones joining them in bed. The primary difference between the King and Super King is the extra 19.5cm in width, meaning more space and comfort to spread out. Research shows that, for many people, the additional space means a more restful, undisturbed sleep.

Sealy’s Super King’s 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. The mattress sits on two separate bases which minimises partner disturbance, making it ideal for shift workers, early risers and restless sleepers.
