Knowing the exact single bed mattress dimensions before purchasing saves you from the most common buying mistakes: a mattress that does not fit the frame, bedding that will not sit properly, or a sleeping surface that does not suit the room.
Standard Single Bed Mattress Dimensions in Singapore
A standard single bed mattress in Singapore measures approximately 91 centimetres wide by 190 centimetres long.
This is the dimension used by most Singapore mattress retailers and the size that standard single bed frames are designed to accommodate. Bedding, mattress covers, and protectors sold locally as single size are made to these dimensions.
The third dimension, mattress depth, varies by construction. Most standard single mattresses range from approximately 15 to 22 centimetres in depth. Thicker options at 25 centimetres or above are available for some constructions.
Super Single Bed Mattress Dimensions
A super single mattress in Singapore measures approximately 107 centimetres wide by 190 centimetres long.
This is the next step up from a standard single, offering 16 centimetres of additional width. The length remains the same at 190 centimetres. Super single is a popular size for solo adult sleepers who want more sleeping space than a standard single provides, and for older teenagers who have outgrown the narrower width.
How Single Bed Dimensions Compare to Other Singapore Sizes
A standard single at 91 by 190 centimetres is the narrowest standard size, suitable for one person in a smaller bedroom.
A super single at 107 by 190 centimetres offers more width for a solo sleeper.
A queen at 152 to 153 by 190 centimetres is the standard couple's size, significantly wider than both single options.
The length of 190 centimetres is consistent across all Singapore standard sizes. Width is the primary differentiating measurement.
Checking Before You Buy
Three practical checks are worth making before purchasing a single bed mattress.
Measure the internal dimensions of your bed frame. Confirm the frame is designed for the specific single dimension you are buying, whether standard single at 91 centimetres or super single at 107 centimetres. Frames for these two sizes are different and are not interchangeable.
Note the mattress depth and check it against the pocket depth of any fitted sheets or mattress protectors you plan to use. A fitted sheet with a 25-centimetre pocket will not fit a 30-centimetre mattress correctly.
For a bunk bed, check the frame's maximum recommended mattress thickness. The upper bunk typically requires a thinner mattress to maintain adequate headroom and guardrail safety. Most bunk frames specify a maximum of 15 to 20 centimetres.
Choosing the Right Construction
Once the dimensions are confirmed, the mattress construction is the key decision. For a child sleeping on a single mattress every night, medium-firm and breathable construction suits most needs in Singapore's climate. For an adult or teenager, construction preferences based on sleeping position and personal comfort become the primary guide.
