King Single sits between Single and Double — longer than many children’s beds and narrower than Double — which suits growing kids’ rooms, teen dens, and compact guest spaces in Australian homes. On Darrah Opens, verify centimetres on each King Single SKU (widths around 106–107 cm and length about 203 cm appear on live Giselle and EasyDreamer pages) rather than assuming every “KS” label matches your frame.
Shop Furniture → Mattresses. Size naming refresher: Queen vs King cm sizes and expansion title #10 (AU size chart). Cot/baby firmness is a different topic — see cot mattresses AU.

What “King Single” means in AU rooms
- Longer sleep length (~203 cm on the SKUs above) helps taller teens
- Narrower than Double — better for tight bedrooms beside wardrobes
- Needs a true King Single frame or base — do not stretch a Single sheet set and expect perfect fit
Measure the existing base inner dimensions before ordering. If you are upgrading from Single, plan new sheets and protectors in King Single sizing.

Extra firm King Single options
The mattress collection lists Giselle King Single extra firm / super firm pocket-spring models (including Leera-style 23 cm tight tops). Open the specific KS URL for firmness number, thickness and expand time before buying for a child who needs firmer support — and check age warnings on any listing (for example some firm Queen pages state not suitable under 3 years).
Kids’ room vs guest bed checklist
Kids / teens
- Confirm age suitability notes on the PDP
- Prefer removable or wipeable covers where listed (Giselle foam zip covers)
- Avoid overly tall stacks if bunks or loft clearances are tight — measure vertical space
- Use a waterproof protector for younger kids; keep breathability in mind for hot rooms
Guest beds
- Unbox early — Cool gel KS 1 day; EasyDreamer KS plan for up to 2 days
- Keep a King Single sheet set washed and ready
- Choose medium firm for most adult guests unless they specifically ask for extra firm
- Foldable foam is an alternative for rare guests (see expansion #17) when storage space beats a permanent KS bed
Frame pairing tips
Artiss bed frames on Darrah Opens centre on Double / Queen / King adult sizes. For King Single, match a dedicated KS base or ensemble listed with that size name. Do not force a KS mattress onto a Single metal frame. If shopping Artiss for other rooms, see Artiss storage/charging checklist.
Who King Single suits in AU homes
Growing teens who outgrew Single length, grandparents’ guest nooks, and narrow rooms where Double width will not clear a wardrobe door. Measure twice — King Single is not a “slightly bigger Single” sheet set.
Sheet and protector planning
Buy true King Single sheets and waterproof protectors before the mattress arrives. Stretching Single sheets creates corner pop-off and uneven wear. Label a spare set for guests so you are not washing the only fitted sheet the morning they land.
Expand timing for guest flips
Giselle Tiberius King Single lists expand within 1 day; EasyDreamer King Single specs emphasise up to 2 days. Unbox early when visitors are flying in for a long weekend.
FAQ
Is King Single the same as Long Single?
Naming varies by retailer. Rely on cm on the Darrah Opens product page and your frame sticker.
Why do Giselle and EasyDreamer KS widths differ (107 vs 106 cm)?
Listings publish their own centimetres. Measure the base and allow for cover tolerance rather than assuming every KS is identical.
What thickness works for kids’ loft beds?
Many loft clearances favour 13–20 cm profiles. A 30 cm cool gel KS may be too tall — measure before buying Tiberius or EasyDreamer height.
Can toddlers use these mattresses?
Follow each PDP’s age warnings. Cot mattresses are a separate category for infants.
What firmness is the Giselle Cool Gel KS?
Medium firm 6.5 on that Tiberius King Single page, with cool gel foam and pocket springs.
How tall is EasyDreamer King Single?
Overall 30 cm on that listing (203 × 106 × 30 cm).
Where do I browse all KS options?
Filter or search King Single inside Furniture → Mattresses.
Will an Artiss Queen frame take a King Single mattress?
No — match a dedicated King Single base. Artiss adult frames centre on Double / Queen / King footprints.
