Knowing the exact dimensions of a single mattress before you shop makes the whole process simpler. It helps you check whether the mattress will fit your bed frame, suit the room, and work for whoever will be sleeping on it.
In Singapore, mattress sizes follow a fairly consistent standard, though small variations can exist between brands. This guide covers what you need to know about single mattress dimensions, how they compare to other sizes, and what else to consider before making your purchase.
Standard Single Mattress Dimensions in Singapore
A standard single mattress in Singapore is approximately 91 cm wide by 190 cm long. This is the most compact adult mattress size available and is designed to fit within standard single bed frames.
In terms of thickness, single mattresses vary. Thinner options of around 15 to 20 cm are common in entry-level models. Higher-quality single mattresses often range from 25 to 30 cm, with additional comfort layers built in for better support and feel.
How Does Single Compare to Other Mattress Sizes?
It helps to see single in context with the other sizes commonly available in Singapore:
• Single: approximately 91 cm x 190 cm
• Super single: approximately 107 cm x 190 cm
• Queen: approximately 152 cm x 190 cm
• King: approximately 183 cm x 190 cm
The single is the narrowest standard size. The super single adds about 16 cm in width, which may not sound like much but can feel noticeably more comfortable for adults who find a single too snug.
When Does a Single Size Make Sense?
A single mattress is a practical choice when space is the main consideration. It works well in:
• Children's bedrooms where a compact footprint allows more room for play and storage.
• Smaller HDB rooms where a larger mattress would leave little walking space.
• Guest or helper rooms that need a comfortable but not oversized sleeping solution.
• Bunk bed setups where the frame dimensions require a specific compact size.
For adults using this as their main sleep surface every night, it is worth considering whether the 91 cm width is sufficient for comfortable rest. If there is any doubt, a super single may be a better fit.
What to Check Before Buying a Single Mattress
Measure the Bed Frame First
Not all single bed frames are exactly the same size. Some are built to accommodate a mattress of exactly 91 cm, while others have a slightly different internal dimension. Always measure your frame before purchasing, particularly if you are buying a replacement for an existing bed.
Check the Thickness
A thicker mattress with more comfort layers will generally feel more supportive and comfortable than a thinner model, especially for everyday use. If the mattress is for a child or an occasional guest, a standard thickness may be sufficient. For regular nightly use, a thicker and better-constructed option tends to hold its shape and feel better over time.
Think About the Materials
Pocket spring mattresses tend to offer better breathability and motion response. Memory foam mattresses feel more cushioned and body-conforming. Latex options are naturally breathable and hypoallergenic. Each material suits a different type of sleeper, so it is worth thinking about who will be using the mattress and what feel they prefer.

Caring for a Single Mattress
A single mattress in regular use benefits from occasional rotation to help it wear evenly. Using a mattress protector from the start keeps the surface cleaner and helps extend the overall lifespan of the mattress. In Singapore's humidity, airing the mattress periodically can also help maintain freshness.
Frequently Asked Questions
Is a single mattress 91 cm wide in Singapore?
Yes, the standard single mattress width in Singapore is approximately 91 cm. Always check the exact dimensions of the specific model you are purchasing, as slight variations can exist between brands.
What is the length of a single mattress?
Most single mattresses in Singapore are 190 cm long, which suits adults up to a reasonable height. If you are taller than average, check whether the mattress length will be sufficient before purchasing.
Is a single mattress the same as a twin?
In some markets, particularly the United States, the twin size is roughly equivalent to a single. However, exact dimensions can vary between countries, so always check the centimetre measurements rather than relying on size names when comparing mattresses from different regions.
Can an adult sleep comfortably on a single mattress?
Yes, but comfort will depend on the person's size and sleep habits. Adults who move around a lot during sleep or prefer more room may find a single too narrow for regular use. A super single offers slightly more width and may be a better fit.
How thick should a single mattress be?
For everyday use, a single mattress of at least 20 to 25 cm tends to offer better support and comfort than thinner options. For children, a slightly thinner mattress can work well, though adequate support is still important.
