How to Choose a King Single Mattress
A king single is often the mattress a teenager will sleep on for many years, so it pays to choose carefully:
- Check the bed frame: King single frames are 107 cm wide. A standard single mattress will not fit properly.
- Match firmness to the sleeper: Medium firm suits most growing bodies. Back and stomach sleepers often prefer firm.
- Think about heat: Teens often sleep warm. Cooling gel mattresses and pocket spring designs help with airflow.
- Plan for growth: At 203 cm long, a king single comfortably fits most adults, so it can last well beyond the teenage years.
- Choose the right base: A sturdy ensemble base or slatted frame protects support and your warranty.
King Single Mattress Size Guide
A king single mattress in Australia measures approximately 107 cm wide by 203 cm long. That's about 15 cm wider and 15 cm longer than a standard single, while still fitting comfortably in a smaller bedroom.
| Size | Approx. Dimensions | Best For |
|---|---|---|
| Single | 92 × 188 cm | Kids and compact rooms |
| King Single | 107 × 203 cm | Teenagers, tall kids, single adults |
| Double | 138 × 188 cm | Single adults wanting more width |
| Queen | 153 × 203 cm | Couples and guest rooms |
If you have the space and want more width, compare a double mattress or queen mattress.

Frequently Asked Questions
A king single mattress in Australia is approximately 107 cm wide by 203 cm long. It's wider and longer than a standard single (92 × 188 cm), which makes it ideal for teenagers and tall sleepers. Measurements can vary slightly by brand, so check the product page before buying bedding.
Yes. A king single suits adults who sleep alone and want more length than a single without the width of a double. At 203 cm long, it fits most adult heights, so it works well in apartments, smaller main bedrooms and guest rooms.
Most teenagers sleep well on a medium firm mattress that supports the spine while they're still growing. Pocket spring and hybrid king singles balance support with comfort, and cooling models help teens who sleep warm. Visit our showroom so your teenager can try a few options first.
At Bedworld, king single mattresses start from $399. Most mid-range pocket spring and orthopaedic models sit between $500 and $1,500, while luxury and premium orthopaedic king singles start from around $2,500. Check each product for current sale pricing.
No. A king single is 15 cm wider and 15 cm longer than a single, so it needs a king single bed frame or base. Using the wrong frame can damage the mattress and may affect your warranty. We stock matching bases and frames for every king single.
