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.
