A quality mattress can cost anywhere from $1,000 to over $5,000 — and a single accidental coffee spill, a child’s bedwetting incident, or a night of heavy sweating can permanently stain it and void the manufacturer’s warranty. The fix is a genuine waterproof mattress protector Australia that blocks liquid without trapping heat.
As Cover & Protect, Australia’s authorised direct-to-consumer distributor of genuine Protect-A-Bed® products, we help Australian families choose between cheap plastic sheets and medical-grade, breathable sleep protection every day. This guide covers what makes a waterproof mattress protector effective, why breathability matters in Australia’s climate, and how to pick the right fabric for your household.
Standard fitted sheets and quilted pads don’t actually protect your mattress — liquid and skin flakes pass straight through cotton into the foam and spring layers underneath. Here’s what that costs you.
Most Australian mattress manufacturers state in their warranty terms that any visible stain or liquid damage voids the warranty immediately. Even if a spring breaks or foam sags prematurely from normal wear, a single stain gives the manufacturer grounds to refuse a repair or replacement claim.
The average person sheds around 1.5 grams of skin flakes and produces up to 1 litre of sweat overnight. Combined, that’s an ideal breeding ground for dust mites, whose populations can double every few weeks — releasing allergens linked to asthma, eczema, and morning nasal congestion.
Australian summers demand high airflow overnight. Older-style plastic protectors trap heat and create a “sauna effect” against the skin. A properly engineered protector needs to be liquid-proof and vapour-permeable at the same time.
The difference between a supermarket plastic sheet and a genuine Protect-A-Bed® protector comes down to one thing: the Miracle Layer™ membrane.
| Fabric Type | Key Benefit | Ideal For | Feel & Texture |
|---|---|---|---|
| TENCEL™ Plant Fabric | Superior moisture-wicking, silky smooth, eco-friendly | Hot sleepers, sensitive skin, luxury feel | Cool, ultra-soft, natural drape |
| Cotton Terry | Highly absorbent towel texture, plush and durable | Everyday family use, kids, bedwetting protection | Cosy, absorbent, classic comfort |
| Smooth Polyester | Lightweight, fast-drying, budget-friendly | Guest rooms, rental properties, travel | Sleek, thin, discreet under sheets |
| AllerZip® Encasement | 6-sided zip closure with BugLock® & Secure Seal® | Severe allergies, asthma, bed bug prevention | Full 360° total mattress seal |
Fitted-style protector (5-sided protection)
An elasticised skirt fits over the mattress like a standard fitted sheet. Best for everyday protection against spills, sweat, and bedwetting, and it’s easy to strip and machine wash on laundry day.
Zip encasement (6-sided protection)
Wraps completely around all six sides of the mattress with a heavy-duty zipper. Best for complete allergen isolation, asthma management, and active bed bug prevention, thanks to patented BugLock® with Secure Seal® technology that closes off every entry and exit point for pests.
Do waterproof mattress protectors make you sweat?
No, provided the membrane has micro-porous breathability. Genuine Protect-A-Bed® protectors use the breathable Miracle Layer™, which lets heat and moisture vapour escape while still keeping liquid spills out.
Will a mattress protector change how my bed feels?
No. Protect-A-Bed® protectors are designed to fit snugly without changing your mattress’s comfort or support. TENCEL™ and Smooth Polyester models are virtually unnoticeable under a regular fitted sheet.
What size waterproof mattress protector do I need?
Protect-A-Bed® protectors are available in all standard Australian mattress sizes — King Single, Double, Queen, King, and Super King — plus deep-wall options for mattresses over 30cm thick. Check your mattress depth before ordering to get a snug, wrinkle-free fit.
Are Protect-A-Bed® protectors safe for babies and children?
Yes. The Cotton Terry range is specifically popular for children’s beds and cots because it’s highly absorbent and machine washable, while remaining breathable enough for safe, comfortable sleep.

Final Verdict
For everyday Australian households, a breathable waterproof mattress protector isn’t optional — it’s the difference between a mattress that lasts its full 10-year warranty and one that’s stained and unsellable within a year. If your household deals with allergies, asthma, or bedwetting, a full six-sided AllerZip® encasement is worth the upgrade over a standard fitted protector. Either way, choosing a genuine Protect-A-Bed® product means you’re getting tested, certified protection rather than a plastic sheet that traps heat and crinkles all night.
