SEALY Mattress Sizes

Our Sealy single and single XL mattresses are a great choice for children of all ages, even adults. Sealy single mattresses are 915mm wide x 1900mm long so they make an ideal first bed, but still give adults enough room to move around. Single beds are also a great space saver.

Children grow fast and Sealy single XL beds are a popular choice for parents who want to get the most out of our ten-year life-span. The Sealy single XL is the same width as a single, but 2030mm long. It provides extra room to stretch out, without taking up too much precious bedroom space. Sealy single XL beds are great for holiday homes and guest rooms as they 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 ideal for older children.

Families are increasingly choosing to invest in our Sealy king singles right from the beginning to save the hassle of changing beds as children grow.

While you’ll appreciate the extra sleep space, Sealy king singles don’t take up too much room, they fit neatly into most bedrooms and are effective space savers in apartments.
