Best Mattress Protector Australia

1. Ecosa Waterproof Mattress Protector (best overall)

Surface: Bamboo blend, 40% bamboo and 60% polyester, 350gsm
Waterproofing: Water-repellent backing
Fit: Elastic skirt fits up to 40cm mattress depth
Price: Check current price
Check price

The Ecosa is the protector most people should buy because it solves the two things that make cheap protectors miserable: heat and noise. The sleep surface is a bamboo and polyester blend that wicks sweat and stays cool, and Ecosa builds the waterproofing into the fabric rather than laminating a plastic sheet on top, so there is none of the crinkle you get from budget units.

It behaves like a deep fitted sheet: the elastic skirt stretches to a 40cm mattress and the whole thing comes off and machine washes on a cold gentle cycle. Reviewers consistently note that you forget it is even waterproof once the bed is made, which is exactly what you want from a protector.

It is water-repellent rather than a fully sealed membrane, so for a bed-wetting child or heavy spills a fully encased option protects more completely. For everyday sweat, the odd spill and general mattress hygiene, it is the easiest one to live with.

Pick if...

You want a soft, quiet, breathable protector that behaves like a fitted sheet and does not sleep hot.

2. Adairs Bamboo Jersey Waterproof Mattress Protector (best waterproof)

Surface: Bamboo viscose jersey
Waterproofing: Full polyurethane waterproof back
Fit: 48cm stretch skirt, 50cm on Super King
Price: Around A$119.99 queen, check current price
Check price

When keeping liquid off the mattress is the whole point, the Adairs Bamboo Jersey is the pick. Unlike water-repellent surfaces, it uses a full polyurethane waterproof back, so spills, sweat and accidents sit on top of the membrane instead of soaking through, while the bamboo viscose jersey face keeps the sleep surface soft and cool.

The fitted skirt is a genuinely deep 48cm on standard sizes and 50cm on Super King, so it grips modern thick and pillow-top mattresses without popping off in the night. It machine washes and tumble dries on low, so cleaning up after an accident is straightforward.

A full waterproof membrane is slightly warmer than a breathable-only surface, and at around A$119.99 for a queen it costs more than a basic cotton protector. For reliable, full-surface waterproofing with a soft bamboo feel, it earns the premium.

Pick if...

You want dependable full-surface waterproofing and a deep skirt for a thick or pillow-top mattress.

3. Adairs Cool Touch Mattress Protector (best cooling)

Surface: Cooling glossy polyester yarn
Feel: Cool-to-touch sleep surface
Fit: 48cm skirt, 50cm on Super King
Price: Often on sale around A$34.99, check current price
Check price

Hot sleepers should start here. The Cool Touch uses a smooth, glossy cooling polyester yarn that feels cold the moment you get into bed and pulls heat away from the skin, which makes a real difference in an Australian summer or under a heavy quilt.

It shares the same deep 48cm fitted skirt as the Adairs waterproof range, so it grips thick mattresses, and it machine washes cold on a delicates cycle. Because it is regularly discounted well below its A$169.99 recommended price, it is also one of the better-value ways to add a cooling layer to an existing bed.

The trade-off is that this is a cooling protector rather than a waterproof one, so it guards against dust and wear but not spills. If you need both cool sleep and spill protection, pair it with a thin waterproof layer or step up to the bamboo waterproof model above.

Pick if...

You sleep hot and want a genuinely cool-to-touch surface more than full spill protection.

4. Adairs Cotton Quilted Waterproof Mattress Protector (best budget)

Surface: Quilted cotton with lofty fibre fill
Waterproofing: Breathable waterproof backing
Fit: 45cm fitted skirt
Price: From around A$59.99 on sale, check current price
Check price

You do not need to spend a fortune for solid protection, and this quilted cotton Adairs proves it. It layers a soft quilted cotton surface with a lofty fibre fill over a breathable waterproof backing, so you get a little cushioning on top of the spill protection, and it is regularly on sale from around A$59.99.

The cotton is treated with an Ultra-Fresh anti-microbial finish to keep it fresher between washes, the 45cm fitted skirt handles most standard mattresses, and Adairs backs it with a five-year guarantee, which is reassuring at this price. It machine washes and tumble dries like the rest of the range.

The skirt is a touch shallower than the deep 48cm bamboo models, so very thick pillow-tops are a firmer fit, and the quilted cotton face is not as cool as bamboo or the cool-touch yarn. As an affordable, comfortable, genuinely waterproof all-rounder, it is hard to fault.

Pick if...

You want dependable, comfortable waterproof protection without paying a premium.

5. Protect-A-Bed AllerZip Mattress Protector (best for allergies and dust mites)

Design: Fully encased, six-sided zip-up
Waterproofing: Waterproof, breathable Miracle Layer membrane
Protection: Dust mites, bed bugs, allergens and bacteria
Price: Around A$219 queen, check current price
Check price

For allergy and asthma sufferers, a surface protector is not enough, and this is where the AllerZip earns its place. Instead of a fitted skirt it fully encases the mattress and zips shut on all six sides with a BugLock and SecureSeal closure, sealing dust mites, bed bugs and their allergens inside the case and away from you.

The smooth polyester face sits over a waterproof, breathable Miracle Layer membrane, so it blocks moisture and stains while still letting the mattress breathe, and it is part of the National Asthma Council Sensitive Choice program. It machine washes and tumble dries, and can be hot washed to kill any dust mites the wash loosens.

It is the priciest pick here at around A$219 for a queen, and fully encased protectors are more effort to fit than a fitted-skirt style. For anyone managing allergies, asthma or a bed-bug worry, that complete seal is exactly the point, and Protect-A-Bed backs it with a 10-year warranty.

Pick if...

You have allergies, asthma or a dust mite or bed bug concern and want the mattress completely sealed.

6. Emma Mattress Protector (best from a mattress brand)

Surface: Soft polyester top
Waterproofing: 100% waterproof polyurethane membrane, antibacterial
Fit: Elastic skirt, compatible with all mattress depths
Price: Check current price
Check price

If your bed is an Emma or another bed-in-a-box, the Emma Mattress Protector is the natural match. It is fully waterproof rather than water-repellent, using a polyurethane membrane that blocks liquid completely, and it is treated to be antibacterial so the sleep surface stays hygienic between washes.

Emma builds it to be crinkle-free and easy to live with: it slips on like a fitted sheet, works with any mattress depth, and machine washes at up to 40C.

Pick if...

You want a fully waterproof, antibacterial protector from a mattress brand.

Surface: Polyester with 200gsm cushioned fill
Waterproofing: Waterproof polyester lining
Fit: Full elastic wrap, mattresses up to 35cm deep
Price: Check current price

How we choose mattress protectors

There is no lab-coat theatre here, just the same process applied to every product. For mattress protectors specifically we:

• Confirmed real Australian availability — every pick is currently sold in Australia through a working retailer listing, and we checked each product link resolves before publishing.
• Judged protection first — whether the protector is water-repellent, fully waterproof or fully encased, because matching that to your actual risk matters more than anything else.
• Weighed feel and breathability — the sleep surface fibre, how hot it sleeps and whether it crinkles, since a protector you find uncomfortable is one you will take off.
• Checked fit and care — skirt depth against modern thick mattresses, plus how easy each one is to machine wash and dry.
• Aggregated verified owner reviews across retailer listings and Australian communities, and re-checked prices at this update.

Sleep Society may earn a commission if you buy through links on this page, which never changes our order or what we say.
