Before buying a super single mattress, knowing the exact dimensions in centimetres is one of the most practical steps you can take. It helps you confirm whether the mattress will fit your bed frame, suit your room layout, and work for the person who will be sleeping on it.
This guide covers the exact super single mattress size in CM, how it compares to other sizes, and what else to check before you make a purchase.
Super Single Mattress Dimensions in Singapore
A standard super single mattress in Singapore measures approximately 107 cm wide by 190 cm long. Thickness varies by model, ranging from around 20 cm for basic options to 30 cm or more for higher-quality mattresses with additional comfort layers.
These dimensions make the super single noticeably wider than a standard single at 91 cm, while still being significantly narrower than a queen at 152 cm. It is designed primarily as a solo sleep surface with a little extra room compared to the standard single.
Mattress Size Comparison: Super Single vs Other Sizes
Here is how the super single compares to other common mattress sizes in Singapore:
• Single: 91 cm x 190 cm
• Super single: 107 cm x 190 cm
• Queen: 152 cm x 190 cm
• King: 183 cm x 190 cm
The difference between a single and a super single is 16 cm in width. That might not sound significant, but when you are lying down, it translates to noticeably more room to move and a more comfortable sleep surface for most adults.
The jump from super single to queen is much larger — about 45 cm — which is why a super single tends to suit solo sleepers while a queen is the more practical choice for couples.
Why the CM Dimensions Matter When Shopping
Checking Your Bed Frame
Bed frames are built to specific internal dimensions. A super single bed frame is sized to hold a mattress of approximately 107 cm wide. Before buying a new mattress, measure the internal width and length of your existing frame to confirm it matches the mattress dimensions.
Some frames have a small margin of tolerance, but a mattress that is too wide will not sit properly, and one that is too narrow may move around during sleep. Always measure carefully rather than assuming.
Fitting the Bed in Your Room
Knowing the mattress dimensions also helps you plan your room layout. Add the mattress width of 107 cm to the space you need on each side for comfortable access. In a typical smaller HDB bedroom, a super single usually fits with enough clearance on either side when positioned along the longer wall.
Buying Bedding and Accessories
Fitted sheets, mattress protectors, and mattress toppers are all sized to match specific mattress dimensions. When buying bedding for a super single, look for products labelled specifically for super single or check that the dimensions match 107 cm x 190 cm.
What to Look for Beyond the Dimensions
Thickness and Comfort Layers
A thicker super single mattress of 25 cm or more tends to offer better comfort and support for everyday use than a thinner option. The additional height usually indicates more substantial comfort layers between the surface and the support core.
Materials and Construction
The dimensions tell you how the mattress fits. The materials tell you how it feels. Pocket spring mattresses offer breathability and responsive support. Memory foam provides cushioned comfort. Natural latex offers cooling breathability with a springy feel. Choose the material that suits the sleep preference of whoever will be using the mattress.

Warranty and Durability
A well-made super single mattress should last eight to ten years with regular care. Check the warranty terms and the quality of the materials before committing to a purchase.
Super Single Bed Frame Considerations
If you are buying a new bed frame alongside a super single mattress, look for one with slats that are no more than 5 to 7 cm apart. This ensures the mattress is adequately supported across its full width and length, which helps it maintain its shape and feel over time.
Solid base bed frames and frames with closely spaced slats tend to work best with foam mattresses. Pocket spring mattresses can work well with either, though a slatted base with good slat spacing is generally preferred.
