Sized for the king single — the grow-into bed. A king single mattress protector is the smart add-on for a teen's room, a tall kid's bed or a single adult who likes the extra length, guarding against spills, sweat and allergens while washing far more easily than the mattress itself. Waterproof and breathable, in a fitted-skirt design that stays put, with a bamboo-blend option for softer, cooler sleep. Part of our wider mattress protectors range, family-owned, priced direct and held in stock locally.

The King Single Protector — for the Grow-Into Bed
The king single is the in-between size that does a lot of growing up — longer than a single for a teen who's shot up, roomy enough for a single adult, and the smart choice for a kid's bed you don't want to replace in two years. A king single mattress protector keeps that bed clean through every stage: spills and study-snacks now, late nights and sleepovers later. It takes the wear so the mattress stays fresh and warranty-intact, and washes far more easily than the mattress ever could.
Why It's Worth It
Built for the teen years
The king single is the classic teen and tall-kid bed. A waterproof layer handles drink spills, sweat and the general chaos of a growing kid's room — and washes clean in minutes.
Healthier sleep
A barrier against dust mites and allergens means a cleaner surface — worthwhile for any teen or guest prone to allergies or asthma.
Protects the mattress
Shields against sweat, stains and wear, extending the mattress's life and helping keep its warranty valid, since stains void many warranties.
Cooler with bamboo
The bamboo-blend option adds a breathable, moisture-wicking surface — softer and cooler for warm Queensland nights and teens who sleep hot.
King Single Size & Fit
An Australian king single mattress measures 106 × 203 cm — about 14 cm wider and 16 cm longer than a standard single, which is exactly why it suits taller sleepers. Our king single protectors are made to match, with a fitted skirt that stretches over the mattress like a deep fitted sheet and holds secure all night. A standard single protector won't fit properly — the extra length leaves it loose — so size to the king single specifically.

Caring for Your Protector
That's the whole point — a protector is far easier to wash than a mattress, which matters most on a busy teen's bed. Most are machine-washable; follow the care label and avoid high heat on the waterproof backing, which can degrade it over time. Wash every couple of weeks, or straight away after a spill, and the king single protector — and the mattress under it — will stay in good shape for years.

King Single Mattress Protector FAQs
What size is a king single mattress protector?
It's made to fit a standard Australian king single mattress — 106 × 203 cm — with a fitted skirt that stretches over the mattress like a deep fitted sheet. That's about 14 cm wider and 16 cm longer than a standard single.
Will a single protector fit a king single bed?
No — the king single is longer and wider than a standard single, so a single protector will sit loose and won't stay secure. Size to the king single specifically for a proper fit.
Are your king single protectors waterproof?
Yes — they're fully waterproof, guarding against spills, sweat and accidents while staying breathable. There's also a bamboo-blend version with the same waterproofing and a softer, cooler top surface, ideal for teens who sleep warm.
Is a king single protector good for a teenager's bed?
It's the ideal size for it — the king single is the classic teen and tall-kid bed, and a waterproof protector handles the spills, sweat and general wear of a busy teen's room while washing clean in minutes.
Can I machine-wash a king single mattress protector?
Most are machine-washable — follow the care label and avoid high heat on the waterproof backing, which can shorten its life. Washing every couple of weeks, or right after a spill, keeps it performing.
Can I buy king single protectors in-store?
Yes — visit any of our five Queensland showrooms in Rocklea, North Ipswich, Beenleigh, Sandgate or Bundall, open seven days. Find addresses and hours on our contact page.
