Sized for the double — the space-smart middle ground. A double mattress protector is the easy add-on for a guest room, a single sleeper who likes room to spread out, or a couple in a compact bedroom, 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 Double Protector — the Space-Smart Choice
The double is the bed that fits where a queen won't — a guest room, a smaller second bedroom, or the bed of a single sleeper who simply likes room to stretch out. A double mattress protector keeps that mattress clean and dry through everything a guest room sees: visitors, the occasional spill, the bed that sits unused then gets a workout over the holidays. 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
Ideal for guest rooms
The double is the classic spare-room size. A protector keeps a less-used mattress hygienic and ready for visitors, so the bed's always fresh when someone needs it.
Healthier sleep
A barrier against dust mites and allergens means a cleaner surface — and on a guest bed that sits between uses, it keeps things fresh rather than musty.
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 guests who sleep hot.
Double Size & Fit
An Australian double mattress measures 137 × 187 cm — wider than a single but the same length, giving one sleeper plenty of room or two a snug fit. Our double protectors are made to match, with a fitted skirt that stretches over the mattress like a deep fitted sheet and holds secure all night. Size to the double specifically — a queen protector will be loose and a single won't reach.

Caring for Your Protector
That's the whole point — a protector is far easier to wash than a mattress. Most are machine-washable; follow the care label and avoid high heat on the waterproof backing, which can degrade it over time. On a guest bed, a quick wash between visits keeps everything fresh; on an everyday double, wash every couple of weeks or straight away after a spill, and both the protector and the mattress under it will stay in good shape for years.

Double Mattress Protector FAQs
What size is a double mattress protector?
It's made to fit a standard Australian double mattress — 137 × 187 cm — with a fitted skirt that stretches over the mattress like a deep fitted sheet. That's wider than a single but the same length.
Is a double the same as a queen?
No — a double is 137 × 187 cm and a queen is 153 × 203 cm, so a queen is both wider and longer. A queen protector will sit loose on a double, so size to the double specifically. If you have a queen, see our queen protectors instead.
Are your double 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.
Is a double protector good for a guest room?
It's the ideal size for one — the double is the classic spare-room bed, and a protector keeps a less-used mattress hygienic and ready for visitors. A quick wash between guests keeps it fresh.
Can I machine-wash a double 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 double 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.
