Why choose a Single XL?
Sleepers of all ages may enjoy the space-saving convenience and comfort of a Single XL, offering the same length as a King or Queen size mattress but the convenient width of a Single.
The narrow size makes this option popular for small bedrooms and limited guest sleeping spaces. If a little more room is required, we recommend the King Single size with an extra 14cm in width.
Otherwise, if you are looking for more room to stretch out, a Double mattress is shorter, but much wider. It is also able to accommodate two people.
