A mattress protector is a thin, washable cover that fits between the fitted sheet and the mattress to block liquid, dust and allergens before they reach the mattress itself. The best mattress protectors in Australia are not the same product as a mattress topper, which adds a layer of cushioning rather than a barrier, so a protector that claims to improve comfort is usually solving the wrong problem.
Protectors sold in Australia generally fall into five types. Waterproof laminate protectors use a thin polyurethane film bonded to a fabric face to block liquid completely. Cotton quilted protectors use a woven barrier and a soft top layer rather than a laminate film. Bamboo protectors use a rayon-from-bamboo weave prized for temperature regulation and a soft handle. Cooling protectors add a mineral or phase-change layer aimed at hot sleepers. Fully encased protectors wrap the entire mattress in a zip-sealed barrier rather than just fitting over the top, aimed at dust mite and bed bug control.
A deep mattress with a pillow top can run to 40 centimetres (about 16 inches) thick, and a protector with a shallow elastic skirt will pop off the corners within a week. The criteria that actually separate a good protector from a bad one are skirt depth, whether the waterproof layer is silent or crinkles under movement, and how many wash cycles the fabric survives before the barrier degrades.
This guide compares ten mattress protectors sold in Australia across waterproofing, fit and fabric feel. Readers after cushioning rather than protection should start with the guide to mattress toppers instead, since the two products solve different problems.

1. Newentor Waterproof Mattress Protector – Best Fully Waterproof
A TPU polyurethane film laminated to a soft Lyocell bamboo-blend face sits behind Newentor’s approach to waterproofing, rather than the woven cotton barrier most budget protectors use. The membrane is bonded rather than coated, which is the detail that determines whether a protector still blocks liquid after fifty washes or starts leaking after ten.
In use, the surface feels closer to a fitted sheet than a plastic cover, and there is no crinkle when someone rolls over during the night. It fits mattresses up to 35 centimetres deep, which covers most queen and king mattresses sold in Australia but not the deepest pillow-top hybrids.
The Double/Queen size ships with reliable stock while the King size has run to pre-order at times, so buyers with a king bed should confirm availability before checking out. Anyone who has replaced a protector because the waterproofing failed within a year is the target buyer here.
Pros
- OEKO-TEX certified fabric
- Silent TPU membrane with no crinkle
- 10-year warranty
Cons
- King size stock runs tighter than Double/Queen
- Premium fabric costs more than a basic cotton cover
Key specs: TPU laminate membrane; Lyocell bamboo-blend surface; fits to 35cm; OEKO-TEX Standard 100 certified; machine washable; 10-year warranty.
CHECK CURRENT PRICE2. Giselle Waterproof Cotton Mattress Protector – Best for Deep Mattresses
This Giselle protector pairs a 250-thread cotton face with a silent liquid-barrier backing, then adds a 40-centimetre elastic skirt built for pillow-top and hybrid mattresses rather than a standard 30-centimetre depth. The quilting layer between the cotton and the barrier is 100gsm polyester over a 90gsm microfiber lining, thicker than most protectors in this price range.
The deep skirt is the reason to pick this over a shallower cover: it stays anchored on mattresses that push a shallow-pocket protector off at the corners within days. The cotton face also breathes noticeably better than a vinyl-coated alternative.
It comes in a King Single size in this listing rather than the full range some buyers expect, so double-check the size chart before ordering for a queen or king bed. Anyone with a deep pillow-top mattress that has outgrown a standard protector is the obvious fit.
Pros
- 40cm elastic skirt suits deep mattresses
- Cotton face breathes well
- Silent waterproof backing
Cons
- Limited to King Single in this listing
- Thicker quilting adds bulk under a fitted sheet
Key specs: Silent liquid-barrier backing; 250T cotton top; 100gsm polyester quilting; 40cm elastic skirt; machine washable; 1-year warranty.
CHECK CURRENT PRICE3. Giselle Water-Resistant Microfiber Mattress Protector – Best Secure 360-Degree Fit
Ozdingo’s microfiber version swaps the cotton face above for a 90gsm brushed microfiber layer, over the same silent liquid-barrier backing. The elastic runs the full perimeter rather than just the corners, which is what keeps a fitted protector from bunching under a fitted sheet.
Brushed microfiber has a softer, warmer handle than woven cotton, closer to a flannelette sheet than a hospital-style cover. The 35-centimetre pocket sits a little shallower than the cotton version, so it suits a standard mattress rather than an extra-deep one.
Buyers who found the cotton version’s thicker quilting off-putting have a lighter-weight option here without giving up the waterproofing. It suits a standard-depth queen or king mattress more than a deep pillow-top.
Pros
- Full-perimeter elastic for a secure fit
- Softer microfiber face
- Same silent waterproof backing as the cotton version
Cons
- Shallower 35cm pocket than the cotton version
- King Single size only in this listing
Key specs: Silent liquid-barrier backing; 90gsm brushed microfiber; 35cm pocket; 360-degree elastic skirt; machine washable; 1-year warranty.
CHECK CURRENT PRICE4. Giselle Bamboo Mattress Protector – Best Bamboo for Allergies
A bamboo terry surface bonded to a water-resistant polyurethane coating is what GoodBuyz sells here, aimed at buyers who want allergen resistance without the plastic feel of a laminate cover. Bamboo fibre is naturally more resistant to dust mites and bacteria than cotton, which is the reason it turns up across most allergy-focused bedding.
The terry weave has more texture than a flat cotton face, and the polyurethane coating sits underneath rather than on top, so the sleeping surface stays soft. It fits mattresses to 35 centimetres deep with a polyester knit skirt.
This is the budget entry into bamboo bedding rather than a premium bamboo product. It suits buyers managing dust mite allergies who do not want to pay for the thicker Mattress Crafters version further down this list.
Pros
- Bamboo terry resists dust mites and bacteria
- Soft surface feel
- Competitively priced for a bamboo protector
Cons
- Warranty terms are shorter than the premium bamboo option below
- Queen size only in this listing
Key specs: Bamboo terry cloth; water-resistant PU coating; polyester knit skirt; fits to 35cm; machine washable.
CHECK CURRENT PRICE5. Dreamaker Quilted Cotton Filled Mattress Protector – Best Budget Pick
Rather than a liquid-barrier membrane, Dreamaker uses a 180gsm cotton loft fill with an anti-bacterial treatment on the top face. It reads more like a thin mattress topper than a plastic-backed cover, which is deliberate: this is a comfort-first protector rather than a full liquid barrier.
The 45-centimetre skirt is the deepest in this list, so it suits an extra-thick mattress even though the fill itself is thinner than the waterproof options above. Machine washing is fine, but the care label calls for line drying rather than a tumble dryer, which slows down the wash cycle.
Buyers chasing dust-mite resistance and a deep-mattress fit at the lowest price point in this guide land here. It is not the pick for anyone who needs a guaranteed liquid barrier, since the cotton fill is absorbent rather than waterproof in the way a laminate membrane is.
Pros
- Deepest skirt in this list at 45cm
- Lowest price point here
- Dust-mite resistant treatment
Cons
- Line-dry only, no tumble drying
- Absorbent fill rather than a full waterproof membrane
Key specs: 180gsm cotton loft fill; anti-bacterial treated top; fits to 45cm; machine washable, line dry.
CHECK CURRENT PRICE6. Mattress Crafters Luxurious Bamboo Mattress Protector – Best Long Warranty
A 10-year replacement warranty, the longest in this guide, backs Mattress Crafters’ bamboo protector, which says something about how confident the brand is in the fabric holding up over time. The rayon-from-bamboo weave is treated for thermal regulation as well as anti-fungal and anti-static properties, rather than bamboo fibre alone.
The brand markets it specifically toward asthma and eczema sufferers, and the hypoallergenic dust-mite barrier is built into the weave rather than added as a coating. It is available across most standard sizes, though Long Single occasionally sells out.
The 10-year warranty is the deciding factor for buyers who plan to keep the same protector for a decade rather than replace it every year or two. It is a step up in price from the GoodBuyz bamboo option above, and the warranty is the reason for that gap.
Pros
- 10-year replacement warranty
- Marketed for asthma and eczema sufferers
- Anti-fungal and anti-static treatment
Cons
- Long Single size occasionally out of stock
- Costs more than the GoodBuyz bamboo protector above
Key specs: Rayon-from-bamboo fabric; thermal-regulating, anti-fungal, anti-static; hypoallergenic dust-mite barrier; machine washable; 10-year warranty.
CHECK CURRENT PRICE7. Protect-A-Bed Cumulus Fitted Waterproof Mattress Protector – Best Antibacterial Protection
Fresche antimicrobial technology sits at the centre of the Cumulus, which the brand says kills 99.99 percent of bacteria on contact rather than simply resisting it passively. The cotton jacquard top sits over a 100 percent polyester Expandall fitted design that stretches rather than relying on a fixed elastic skirt.
The Expandall fit means it works across a wider range of mattress depths than a protector with a set skirt measurement, since the whole panel stretches rather than just the corners. It is also rated safe for use with an electric blanket, which several protectors in this guide do not confirm.
Buyers who run an electric blanket through winter and need a protector that will not trap heat or degrade under it should start here rather than with a straight waterproof laminate. The five-year guarantee sits in the middle of this guide’s warranty range.
Pros
- Fresche antimicrobial technology
- Stretch-fit design suits varying mattress depths
- Confirmed safe with an electric blanket
Cons
- Costs more than the dropship-sourced options earlier in this list
- Five-year guarantee is shorter than the bamboo options
Key specs: Fresche antimicrobial technology; cotton jacquard top; Expandall stretch fit; electric-blanket safe; machine washable; 5-year guarantee.
CHECK CURRENT PRICE8. TENCEL Signature Series Mattress Protector – Best Eco-Friendly Fabric
Tencel fibre, a eucalyptus-derived material, covers this protector’s face over what the brand calls a Miracle Membrane waterproof barrier rather than a standard PU laminate. Tencel is produced in a closed-loop process that reuses more solvent than standard rayon manufacturing, which is the environmental angle behind the fabric choice.
Protection covers all five sides of the mattress rather than just the top, and the membrane is rated to absorb up to a litre of fluid on a queen size before it saturates. That five-side coverage matters more for buyers with pets or young children than for a single adult sleeper.
The Tencel face is noticeably cooler against the skin than cotton or bamboo, which suits a hot sleeper who still wants five-side coverage rather than just a fitted top. It carries a 10-year warranty in line with the other premium protectors in this guide.
Pros
- Five-side protection, not just the top
- Eucalyptus-based Tencel fibre feels cool against skin
- OEKO-TEX certified
Cons
- Priced above the fitted-only protectors in this guide
- Five-side design takes longer to fit than a simple fitted sheet
Key specs: Miracle Membrane waterproof barrier; Tencel fibre face; 5-side protection; absorbs up to 1L on queen; OEKO-TEX Standard 100; 10-year warranty.
CHECK CURRENT PRICE9. Allerzip Fully Encased Mattress Protector With Bed Bug Locker – Best Hypoallergenic
Full mattress encasement rather than a simple fitted top is the whole idea behind Allerzip, which uses Protect-A-Bed’s Miracle Layer membrane on all five sides plus a Bug Lock zipper with a SecureSeal flap over the zip track. That zip-and-flap combination is specifically engineered to stop bed bugs entering or leaving through the zipper, which a standard fitted protector cannot do at all.
Full encasement changes how the mattress is protected: rather than catching spills on top, it seals the whole mattress against dust mites, mould and bacteria from every direction. Fitting it takes longer than a fitted protector since the mattress has to be lifted and the zip run the full way around.
This is the pick for a genuine dust mite or bed bug concern rather than general spill protection, worth calling out separately from the fitted-style protectors elsewhere in this guide since it solves a different problem. It is also rated safe with an electric blanket, same as the Cumulus above.
Pros
- Full 5-side encasement with a Bug Lock zip seal
- Blocks bed bugs, not just dust mites and spills
- Electric-blanket safe
Cons
- Slower to fit than a standard fitted protector
- Overkill for buyers who only want basic waterproofing
Key specs: Protect-A-Bed Miracle Layer, 5-side waterproof encasement; Bug Lock zipper with SecureSeal flap; anti-bacterial and anti-mould; machine washable; electric-blanket safe.
CHECK CURRENT PRICE10. Cooltouch Mattress Protector – Best for Hot Sleepers
A natural mica mineral fibre in the top layer is Cooltouch’s answer to sleeping hot under a protector, sitting over a breathable waterproof membrane on the underside rather than a heat-trapping laminate. Mica fibre is the same category of mineral additive used in some cooling mattress toppers, applied here to a protector instead.
The skirt runs 40 centimetres deep and stretches to 55 centimetres, covering everything from a standard mattress to a thick pillow-top without needing a different size. The breathable underside is the detail that separates it from a straight vinyl-backed protector, which can trap heat against the mattress overnight.
Hot sleepers who have avoided mattress protectors because a previous one made the bed feel warmer are the target buyer, and the 10-year warranty means it should outlast several mattress cycles rather than needing replacement after a season or two.
Pros
- Mica mineral fibre for temperature regulation
- Skirt stretches from 40cm to 55cm
- Breathable waterproof underside
Cons
- Costs more than the budget cotton and bamboo options
- Mineral-fibre treatment adds a small amount of stiffness compared to a plain cotton face
Key specs: Breathable waterproof membrane; mica mineral fibre for cooling; 40cm skirt stretching to 55cm; anti-bacterial; machine washable; 10-year warranty.
CHECK CURRENT PRICEHow to Choose Mattress Protectors in Australia
Waterproofing type decides whether the protector blocks liquid completely or slows it down. A bonded TPU or polyurethane laminate is the most reliable barrier, since the film sits under the fabric rather than as a separate coating that can flake over time. A cotton-quilted protector without a laminate is more breathable but relies on the weave itself to slow rather than stop moisture, which suits general dust and sweat protection more than a genuine spill.
Skirt depth matters more than most buyers expect until a protector pops off the corners of a pillow-top mattress in the middle of the night. Standard mattresses sit around 25 to 30 centimetres deep, but a pillow-top or hybrid mattress can run to 40 centimetres or more. Check the listed pocket depth against the actual mattress before ordering, since an undersized skirt is the single most common return reason for this product category.
Breathability separates a comfortable protector from one that makes the bed feel warmer overnight. A vinyl-backed laminate with no breathable treatment traps heat against the mattress, while a membrane built into a woven or bamboo face lets air pass through. Buyers who run hot, or who already use an electric blanket, should check for an explicit breathable or electric-blanket-safe claim rather than assuming any waterproof protector will do.
Fabric feel comes down to cotton, bamboo or microfiber, and the difference is mostly about temperature and softness rather than function. Cotton is the standard choice and breathes well. Bamboo runs cooler and has some natural antibacterial properties. Microfiber feels closer to a flannelette sheet and tends to be the softest against bare skin.
Allergen and hygiene needs should decide between a fitted protector and a fully encased one. A fitted protector covers the top and slightly down the sides, which is enough for spill and general dust protection. A fully encased protector zips around the entire mattress and is the only style that genuinely blocks bed bugs, since insects can otherwise enter through the sides or base that a fitted cover leaves open. Readers weighing that decision alongside a mattress purchase itself can compare options in the guide to queen mattresses in Australia.
Washability and warranty length are the two figures worth checking before checkout. Most protectors in this guide are machine washable, but a few call for line drying rather than a tumble dryer, which is worth knowing before the first spill happens late at night. Warranty length also tracks fairly closely with price: budget cotton protectors carry a year, while the bamboo and waterproof-membrane options in this guide run to ten years.
Frequently Asked Questions
What is the difference between a mattress protector and a mattress topper?
A mattress protector is a thin, washable barrier that blocks liquid, dust and allergens, while a mattress topper is a thicker comfort layer added on top of the mattress to change its feel. A protector sits under the fitted sheet against the mattress itself, and the two products can be used together without conflicting.
Do mattress protectors make you sleep hot?
A basic vinyl-backed protector without a breathable treatment can trap heat against the mattress. Protectors built with a bonded TPU membrane, bamboo fabric or a dedicated cooling layer are designed to let air pass through and do not carry the same heat-trapping reputation as older plastic-backed covers.
Can I use an electric blanket with a mattress protector?
Most fitted mattress protectors are safe to use under an electric blanket, but not all brands confirm it explicitly. Checking for an electric-blanket-safe claim on the product listing is worth doing before combining the two, since some waterproof membranes are not rated for sustained heat contact.
How often should I wash a mattress protector?
Every four to eight weeks under normal use, and immediately after any spill or accident, is the general guidance most brands give. Washing more often than the fabric is rated for can wear down a laminate membrane faster than the stated warranty period assumes.
What size mattress protector do I need for a deep mattress?
A mattress deeper than 30 centimetres, which includes most pillow-top and hybrid mattresses, needs a protector with an elastic skirt rated to at least 35 to 40 centimetres. Checking the listed pocket depth against the actual mattress height avoids the most common fit problem with this product.
Do mattress protectors stop dust mites and allergies?
A fitted protector with a hypoallergenic or dust-mite-resistant claim reduces exposure but does not fully seal the mattress. A fully encased protector with a zip closure blocks dust mites and bed bugs from the entire mattress, not just the top surface, and is the stronger option for a genuine allergy or bed bug concern.
Verdict
Most buyers in Australia looking for reliable, all-round waterproofing without paying a premium should start with the Giselle Waterproof Cotton Mattress Protector, thanks to its deep 40-centimetre skirt and silent barrier. Anyone managing allergies or asthma gets more long-term value from the Mattress Crafters Luxurious Bamboo Mattress Protector and its 10-year warranty, while hot sleepers who have given up on protectors making the bed feel warmer should look at the Cooltouch Mattress Protector instead. Between them, this guide’s ten options cover deep mattresses, allergy protection and temperature control without requiring a switch to a different product entirely.
