The term single double mattress is occasionally used in the mattress market and can cause some confusion. In Singapore, it most commonly refers to the super single, a size that sits between a standard single and a standard double in terms of width. This guide clarifies the size, how it compares to adjacent options, and who it is most suited to.
What Single Double Mattress Typically Means
In the Singapore market, the term single double is sometimes used to describe a mattress that is wider than a standard single but narrower than a standard double or queen. This corresponds most closely to the super single, which measures approximately 107 centimetres wide by 190 centimetres long.
The standard single in Singapore measures 91 centimetres wide by 190 centimetres long. The standard double measures approximately 137 centimetres wide by 190 centimetres long. The super single at 107 centimetres sits between these two, wider than a single but narrower than a double.
Some retailers may use the term single double to mean a double bed that accommodates a single sleeper comfortably, essentially using double to indicate extra space for one person. In this usage, it is describing a standard double at 137 by 190 centimetres.
When you see the term single double, always confirm the exact centimetre dimensions before purchasing to clarify which size is actually being referenced.
Who the Super Single or Single Double Suits
The super single or single double is well-suited to specific situations.
A solo adult sleeper who wants more room than a standard single provides. The extra 16 centimetres of width makes a noticeable difference to sleeping comfort for an adult who moves during the night or simply prefers more personal space.
A teenager transitioning from a child's single bed. As teenagers grow and their sleeping habits change, the additional width of a super single provides more appropriate sleeping space without requiring the jump to a full double or queen.
A bedroom where a double or queen is too wide to sit comfortably with adequate clearance around it. In compact bedrooms in HDB flats or condominiums, a super single may provide the right balance of sleeping space and room usability.
A solo occupant in a spare room who would benefit from more than a standard single but does not need a full couple's size.
Comparing to Adjacent Sizes
A standard single at 91 by 190 centimetres suits one person comfortably in a smaller bedroom, particularly for children.
A super single or single double at 107 by 190 centimetres offers more width for a solo adult sleeper while remaining narrower than a full double.
A double at 137 by 190 centimetres provides substantially more width and is generally the smallest size suitable for two people sleeping together on a regular basis.
A queen at 152 to 153 by 190 centimetres is the standard couple's size in Singapore.
Choosing the Right Construction
Regardless of size label, the construction of the mattress determines how it performs. For a super single used as a primary sleeping surface, quality materials and a construction suited to Singapore's climate are the relevant criteria.
A pocketed spring mattress provides natural airflow through the spring core and responsive support. A memory foam mattress provides contouring pressure relief and motion absorption. A latex mattress offers naturally breathable, responsive comfort suited to warm sleeping environments.
