For a UK Double bed, the specialist and Dunelm examples have similar but not identical dimensions and different care instructions. A general price range also needs to be separated from a selected-size price. This guide focuses on these buying checks without ranking waterproofing, comfort or value.
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 UK — Waterproof Mattress Protector
The Double selector lists 137 × 190 × 30 cm at GBP 59. Material is described as an 80% cotton terry surface with TPU backing. The FAQ allows warm gentle washing and low tumble drying or air drying.
Limitation: Other sizes include a 46 cm selector depth while the general FAQ says up to 40 cm. Do not extend the Double specification to every size. The page advertises free delivery above GBP 75 and Express Delivery at GBP 25 below that threshold; a final address-specific order total and return destination were not checked.
Dunelm — Fogarty Cotton Waterproof Mattress Protector
Dunelm lists Double at 135 × 190 cm with a 30 cm depth. The page’s price-drop note gives GBP 22 for Double/30 cm, within a GBP 14–32 range. It declares a cotton cover, polyurethane reverse and polypropylene skirt; washing at 40°C is allowed but tumble drying is not.
Limitation: The price-drop note is not a verified basket total or local-store stock check. The selected query URL failed retrieval, so these facts come from the current primary product record without a selected URL parameter.
The specialist Double is listed 2 cm wider than Dunelm’s Double. Measure your own mattress rather than treating the label as a guarantee. Neither a cotton percentage nor a price difference proves better liquid resistance. For a dryer-dependent household, confirm the care label before purchase; the documented instructions differ even though both are sold as waterproof protectors.
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 GBP 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.
Does the headline range give the Double price?
Not reliably. Dunelm’s page separately identifies its Double/30 cm price, while the specialist has a Double option price. Check those exact variants and any shipping charge before making a basket comparison.
Methodology and limitations
We checked the repository’s MattressProtector country inventory, then primary retailer or specialist records relevant to United Kingdom. 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.
