Australian shoppers can compare a dedicated Mattress Protector Company listing with Kmart’s Queen fitted protector, but the useful differences are fit and care rather than a claimed quality winner. The specialist’s Queen selector and general depth guidance disagree. This non-ranking guide keeps that uncertainty visible instead of assuming that a higher price buys better protection.
Scope: Ordinary adult household mattress covers. This guide does not recommend infant sleep products, clinical incontinence equipment or compatibility with electric blankets. A thin protector, padded cover and zipped encasement are different products.

Named options and evidence limits
Mattress Protector Company Australia — Waterproof Mattress Protector
The Queen option is listed at AUD 110 with dimensions 152 × 203 × 46 cm. The seller describes an 80% cotton terry top, TPU membrane and fitted skirt. Its care instructions allow a warm gentle wash and low tumble drying.
Limitation: The general specifications instead state a maximum 40 cm mattress depth. Confirm fit before relying on the 46 cm selector. The rest of the top-fabric composition is not specified, and the page does not publish a certificate number for its testing claim. Free Australian delivery is advertised above AUD 75; actual dispatch origin and return address were not verified.
Kmart — Waterproof Fitted Mattress Protector, Queen, SKU 42127321
The product record shows AUD 30 and dimensions 203 × 152 cm with a 40 cm height. It lists cotton pile, polyester base and skirt, and polyurethane backing. Care is a warm delicate machine wash; tumble drying is prohibited.
Limitation: Postcode-specific stock, delivery and a complete order total were not checked. The material and care entries are retailer specifications, not findings about liquid resistance or antibacterial performance.
The listed Queen length and width align, but the depth evidence does not support calling the two covers interchangeable on a deep mattress. If your laundry routine depends on a dryer, the documented care difference matters before price. Ask the specialist to reconcile its two depth figures, and check the actual packaging label on either purchase.
Checks before choosing
Measure the mattress, not just its size name
Write down width, length and depth, including any topper that will sit inside the cover. Ask whether the listed depth is the maximum mattress height or the unstretched skirt dimension. Compare actual numbers before selecting a Queen, Double or King label. Where a size selector contradicts the general fit description, obtain written confirmation for your measurements before ordering.
Choose the construction you actually need
A fitted protector wraps over the mattress like a sheet. A padded protector adds a filling layer; a zipped encasement closes differently. These formats should not be treated as equivalent simply because all use the word protector. Ask which surfaces carry the barrier, how the seams are constructed and whether the underside is enclosed. Do not infer complete enclosure or pest control from a fitted skirt.
Read each material and care declaration
The top fabric, backing, filling and skirt can have different compositions. Cotton on the face does not mean an entirely cotton product, and bamboo wording alone does not establish fibre percentages. Obtain the supplied care label: some examples below allow low tumble drying while others prohibit it. Do not transfer one brand’s instructions to another. No wash-durability or waterproofing test was performed for this guide.
Clarify warranty, returns and buying costs
Before opening or washing the item, confirm the return conditions, deadline, return address and who pays postage. Ask for the written warranty and its exclusions, including whether it covers only the protector or any consequential mattress damage. Add delivery and any disclosed import charges to the selected item price. A country-domain name alone does not establish domestic dispatch or a local return address.
Get an address-specific offer
Ask for a written total in AUD identifying the selected size, colour and included pieces. Record any separate shipping charge, tax or import-cost treatment, dispatch origin, return address and warranty exclusions. Missing details here are unverified, not a finding that a seller provides no warranty or returns. Where no current offer could be read, the source is explicitly an enquiry or catalogue reference, not a confirmed in-stock option.
Is the specialist Queen confirmed to fit a 46 cm mattress?
No. Its selector says 46 cm while its general specifications say up to 40 cm. The guide records the disagreement rather than selecting the more favourable number.
Methodology and limitations
We checked the repository’s MattressProtector country inventory, then primary retailer or specialist records relevant to Australia. We used the approved non-ranking buying-guide format because complete product equivalence, selected-variant offers or specialist specifications were not sufficiently established. This selected-source guide is not an exhaustive market survey. Retailer claims are attributed and source-access limitations are visible; overseas prices are not ranked as local offers.
No hands-on testing, scoring, certification, safety assessment or performance ranking was performed. Testimonials and ratings are not findings. Item prices are dated observations, not guaranteed checkout totals. No cheapest-product, cooling, health, allergy-suitability or lifespan claim is made. We have not contacted sellers or submitted forms, orders or payments.
