If you have come across the term 'king single mattress' while browsing online, you may have noticed that it is not a size commonly listed by Singapore mattress brands. That is because 'king single' is primarily an Australian sizing term — and it does not directly correspond to a standard Singapore size.
This guide explains what a king single mattress is, how it compares to sizes available in Singapore, and what the right equivalent is for local shoppers.
What Is a King Single Mattress?
A king single mattress is a sizing term used primarily in Australia. It typically measures approximately 107 cm wide by 203 cm long — making it wider than a standard single and longer than most standard Singapore mattress lengths.
The name can be confusing because it uses the word 'king', but it is not a king size mattress in the way Singapore shoppers would understand the term. It is essentially an oversized single — wider and slightly longer than a standard single, designed for a solo sleeper who wants more room.
Does Singapore Have a King Single Equivalent?
The closest equivalent to a king single in Singapore is the super single mattress. A super single measures approximately 107 cm wide by 190 cm long — the same width as a king single, though typically 13 cm shorter in length.
For most Singapore sleepers, the super single is the practical answer to what a king single offers. It provides noticeably more width than a standard single while remaining compact enough for smaller HDB and condo bedrooms.
If you are taller than average and the 190 cm length of a super single feels limiting, it is worth discussing this with the mattress brand before purchasing. Some brands offer or can source longer length options on request.
Super Single vs Standard Single: The Practical Difference
The standard single at 91 cm wide is the most compact adult mattress size available. At 107 cm wide, a super single gives you an additional 16 cm of width — enough to make a meaningful difference when you are lying down and moving during sleep.
For adults who find a standard single too narrow for everyday comfortable use, the super single is the natural next step. It fits in most bedroom layouts where a single would work, without requiring a significantly larger room footprint.
Who Is the Super Single Best For?
• Solo adults who want more room than a standard single provides without the size of a queen.
• Teenagers who have outgrown a standard single and need more space to sleep comfortably.
• Sleepers in smaller HDB or condo rooms where a queen would leave too little walking space.
• Anyone who has searched for a 'king single' and wants the closest Singapore equivalent.
