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.

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

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 mattress

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.

Research shows that, for many people, the additional space means a more restful, undisturbed sleep.

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.
