A single mattress is one of those purchases that looks simple on the surface but has more to it than most people expect. There is the size to confirm, the materials to understand, the right firmness to find, and the right brand to trust.
This guide gives you a complete and honest overview of everything worth knowing before buying a single mattress in Singapore — from the basics through to the details that actually affect how well you sleep.
Single Mattress Size in Singapore
A standard single mattress in Singapore measures approximately 91 cm wide by 190 cm long. This is the most compact standard mattress size and fits a standard single bed frame comfortably in most smaller bedroom layouts.
If 91 cm feels narrow — and for some adults it genuinely is — the super single at 107 cm wide is the natural next step. It adds about 16 cm of width and fits within a similar room footprint, making it a practical upgrade without needing to move to a full queen.
Who Typically Buys a Single Mattress in Singapore?
The single mattress suits a wider range of situations than many people initially consider:
• Children moving from a cot to their first proper bed, typically between ages two and three.
• Teenagers in their own room who have not yet needed to upgrade to a larger size.
• Solo adults in HDB rooms, condos, or studio apartments where floor space is limited.
• Guest bedrooms and helper rooms where a comfortable but space-efficient solution is needed.
• Bunk beds and loft frames that require a specific compact size.
In each case, the quality of the mattress matters. A single used every night by a child or adult deserves the same consideration given to any larger mattress purchase.
The Main Mattress Types Available in Single
Pocket Spring
Pocket spring mattresses use individually wrapped coils that move more independently from one another. This gives a responsive feel and allows natural airflow through the mattress — a genuine advantage in Singapore's warm and humid climate. The motion-independent springs also mean less bounce and more settled sleep for restless sleepers.
Browse the Somnuz pocketed spring mattress collection to explore single size options designed with breathable support in mind.
Memory Foam
Memory foam contours closely to the body and responds slowly to pressure, creating a cushioned and enveloping feel. It works well for solo sleepers who prefer a softer surface and want strong pressure relief. In Singapore's climate, look for models with breathable cover fabrics or open-cell foam constructions to manage heat more effectively.
The Somnuz memory foam mattress range is available in single size for sleepers who prefer a cushioned, close-contouring feel.
Natural Latex
Natural latex has a springy, responsive feel and tends to sleep cooler than memory foam. It is naturally hypoallergenic and durable — a particularly strong choice for children's rooms or allergy-sensitive households. It also offers good breathability, which suits Singapore's humidity well.

Choosing the Right Firmness
Firmness in a single mattress matters just as much as in a larger size. The right level depends on who will be sleeping on it and how they sleep.
• Soft to medium: suited to side sleepers or lighter individuals who want cushioning at the shoulders and hips.
• Medium-firm: a versatile starting point for most sleepers, balancing comfort with steady support.
• Firm: better suited to back or stomach sleepers who prefer a more stable and supportive surface.
For children, a medium-firm option is generally the most practical choice — steady enough for growing bodies, comfortable enough for everyday use. For adults, personal preference plays a bigger role, which is why trying different firmness levels in person before buying is always worthwhile.
Singapore-Specific Considerations
Breathability Matters Here More Than Elsewhere
What is optional in a cooler climate is genuinely important in Singapore. A mattress that retains heat will affect sleep quality — even with air conditioning, a poorly breathable mattress can make the surface feel warm and uncomfortable by the middle of the night. Pocket spring and latex constructions both offer better natural airflow than dense foam alternatives.
Hypoallergenic Options Are Worth Considering
Singapore's humidity creates conditions where dust mites thrive more easily. For children's rooms or any household member with respiratory sensitivities, a mattress with anti-dust mite or hypoallergenic properties contributes to a cleaner and more comfortable sleep environment over time.
Room Layout and Frame Fit
In Singapore's compact homes, a single mattress often needs to work within a carefully considered room layout. Measure your room and your bed frame before ordering. Confirm the exact internal dimensions of the frame, check slat spacing, and plan where other furniture will sit relative to the bed before finalising your choice.
Frequently Asked Questions
What is the difference between a single and a super single mattress?
A single mattress is 91 cm wide. A super single is 107 cm wide. Both are 190 cm long in Singapore. The extra 16 cm of width in a super single makes a noticeable difference for adults who find the standard single too narrow for comfortable everyday sleep.
Is a single mattress good enough for an adult to sleep on every night?
Yes, provided the mattress is well-made with quality materials and appropriate firmness. The width of 91 cm is adequate for most adults sleeping alone. If you are a restless sleeper or simply prefer more room, a super single is worth considering.
What mattress should I buy for a child's single bed?
A medium-firm pocket spring or natural latex mattress is generally a strong choice for children. Both offer breathable comfort, good support for growing bodies, and hypoallergenic properties that are particularly useful in Singapore's humidity. Pair with a waterproof mattress protector from day one.
Should I buy the thickest single mattress available?
Not necessarily. Thickness indicates more comfort layers, but those layers need to be made from quality materials to make a meaningful difference. A 25 cm mattress with quality foam and spring construction offers better sleep than a 30 cm mattress with poorly made padding. Focus on what is inside the mattress rather than height alone.
Can I try single mattresses in person at a Somnuz showroom?
Yes. The Somnuz experience centre at 134 Joo Seng Road, Level 2, Luventus Building, Singapore 368359 is open daily from 11:30 am to 9:00 pm. Walk in any time to try the range across different types and firmness levels.
