Choosing the Right King Single Mattress
The king single solves a specific problem: a standard single has run out of room, but a double would swallow the floor space — or there isn't a partner to share it with. At 106 × 203 cm it gives a king's worth of length with a footprint that still fits a teenager's bedroom, a study, a bunk or a guest room. This guide covers who it suits, the builds we stock, and how to land on the right firmness.
Who a king single suits best
- Growing teens: the most common reason Queensland families upgrade — a medium-firm pocket spring king single supports a developing spine and lasts through the teenage years.
- Taller sleepers: at 203 cm it's the same length as a king, so anyone who hangs off the end of a single (187 cm) gets a proper 16 cm more to stretch into.
- Guest rooms, FIFO & shared accommodation: generous for a single sleeper without committing the space — or the budget — of a double.
- Compact rooms & studies: when you want more bed than a single but the room can't take a double's width.
King single mattress types we stock
The right build depends on the sleeper and on the climate — Brisbane and Gold Coast nights run warm and humid, so breathability earns its keep here more than in the southern states.
- Pocket spring: individually-wrapped (often 5-zone) springs that support the body in sections — the popular, durable pick for growing teens.
- Memory foam: contouring pressure relief; gel-infused options sleep cooler through humid South-East Queensland nights.
- Bonnell spring: a firmer, value innerspring — the most budget-friendly way into a king single.
- Euro-top & memory-foam hybrid: a plush comfort layer over a supportive core for cushioned softness without losing structure.
- Mattress in a box: compressed and boxed so it fits in the car and sets up in minutes — handy for teen rooms and quick turnarounds.
- Bamboo-fabric range: breathable bamboo covers that help wick heat on warm nights.
Firmness & feel
For growing children and teenagers a medium-firm king single generally gives the best spinal support. Sleepers who prefer a softer, cushioned surface should look at our soft & plush range. Firmness is personal, though — two minutes lying on a few in one of our showrooms settles it faster than any description on a screen.
King single, single or double?
A king single is 106 × 203 cm — wider and 16 cm longer than a standard single (92 × 187 cm), without the width jump of a double. If the sleeper is tall or has simply grown out of a single but the room can't take a double, the king single is the size that fits the gap.

Is a king single big enough for a teenager or an adult?
Yes — at 203 cm it's the same length as a king, so it comfortably suits taller teens and single adults who outgrow a standard single. The compact 106 cm width is what lets it fit rooms a double can't.
