Best mattress protectors: six compared, and the £13 one ties for first
A mattress protector is one of the few things in the house that sits between you and eight hours of breathing, sweating and shedding skin. Most people buy on price or on brand. We went looking at what these six are actually made of, what they claim, and what owners say about them months down the line.

Mrs House is independent. Nobody pays for a place in a ranking here, and no brand saw this page before it went live.
The short answer
Buy the Panda Bamboo at about £33 if you want the nicest one, or the Utopia encasement at about £13 if you want the most proof for the least money. They finish level on our scoring and Panda only takes the top slot on a tiebreak.
- Best overall: Panda Bamboo, £33.30 for a double. Bamboo face over a TPU film, OEKO-TEX claimed but no number published.
- Best value, and best for bed bugs: Utopia Bedding Encasement, £13.49. Zips on all six sides, and its OEKO-TEX number is the only one here that checks out against the register.
- Cleanest to sleep on: Woolroom Deluxe Washable Wool, £119.99. Not waterproof, so only if nothing is ever getting spilled.
A waterproof protector is a plastic film with fabric on it. That is the trade, and on most beds it is worth making.
How we assessed these
Six protectors, one method, applied to all of them equally. We read every published specification and chased down what the waterproof layer is actually made of in each one, because that is the part in contact with you all night and it is the thing brands are vaguest about. We checked every certification claim against the certifying body rather than the brand’s own marketing. And we read several thousand owner reviews across Amazon, Dunelm, Very, Judge.me and the brands’ own sites, weighted deliberately towards the one and two star reviews, because that is where the truth about noise, heat, shrinkage and fit actually lives. A protector that fails does so after about the fourth wash, and only owners will tell you that.
Every product is scored on the same five parts: does it work (35 per cent), what it is made of (25 per cent), value (15 per cent), everyday use (15 per cent) and honesty of the claims (10 per cent). Where a brand would not publish something we asked for, we say so on the page and we mark it down for it.
On certification specifically, we did not accept a logo as evidence. We looked for a certificate number on each product page, then put any number we found through the certifying body’s own public register to confirm it was live, which class it was issued in, and whether the scope actually covers a waterproof mattress protector rather than something else the brand makes. Only one of these six survived that. Where a brand shows an OEKO-TEX logo but publishes no number, we have said so rather than counting it.

The two we would actually buy
Best overall
Our winner
1. Panda Bamboo Mattress Protector
★★★★☆ 3.9 / 5
The waterproof layer here is TPU, a polyurethane film, rather than the vinyl you find on cheap protectors, and that is the right choice. Panda says every thread, zipper, button and dye is OEKO-TEX Standard 100 certified. We wanted to check that and we could not, because Panda publishes no certificate number anywhere on the product page. We are not saying it is untrue. We are saying a £13 competitor on this page publishes a number that checks out, and a £33 British brand does not, which is a strange way round.
Owners are honest about the trade-off. A minority describe a plastic rustle and a slippery surface, and a handful say they woke up hot, which is the price of any film-based protector no matter what the marketing says about breathability. One Dunelm reviewer said it was like lying on a crisp packet. Most people do not report that, but enough do that you should know before you buy. It scores 4.61 out of 5 across 540 reviews on Panda’s own site and 4.59 from 434 at Dunelm, which is a consistent picture from two separate pools.
Pros
- The waterproof layer is a breathable TPU film rather than the vinyl or PVC you normally get at this price
- The fitted skirt stretches over deep mattresses and stays put through the night
- Two separate pools of owners agree on it: 4.61 out of 5 from 540 reviews on Panda’s own site and 4.59 from 434 at Dunelm
Cons
- A faint plastic rustle when you move, and a few owners say it is enough to wake them
- The surface is slippery, so a fitted sheet can shift over it
- No certificate number is published for the fabric claims
- A minority sleep warmer with it on than without it
Buy it if you want a fitted protector that is waterproof, comfortable and sanely priced. Skip it if noise ruins your sleep.
Ties for first
Certificate checks out
2. Utopia Bedding Premium Waterproof Encasement
★★★★☆ 3.9 / 5
A full zipped encasement rather than a fitted skirt, so it seals the mattress on all six sides. That makes it the only one here that does anything useful about bed bugs or a mattress that already smells. TPU backing all the way round, machine washable and, unusually, tumble dryable, which matters more than it sounds when you have stripped a bed at two in the morning.
Here is the surprise. Utopia is the only product on this page that publishes an OEKO-TEX certificate number, 2023OK1318, issued by AITEX. We put it through OEKO-TEX’s own label check and it comes back valid, Standard 100 in Product Class I, which is the strictest class, the one written for articles for babies. The scope names waterproof mattress encasements in polyester with TPU lamination, so it covers this exact product rather than something else in the range. Every other brand here asks you to take the certification on trust. This one lets you check it.
It is still 100 per cent polyester, so nothing natural touches you, and the badge is buried inside a marketing image rather than written into the listing. Amazon’s own review summary is blunt about the split on waterproofing: most buyers are happy, a real minority say liquid got through. Across 12,889 ratings it averages 4.5 out of 5 with a 74 per cent five star share, so the balance is clearly positive, but a 4 per cent one star tail usually points to variable quality control.
Pros
- The only certification claim on this page we could verify: OEKO-TEX certificate 2023OK1318 from AITEX, Class I, and the scope names this exact type of product
- A full zip encasement, so it seals all six sides against spills and against bed bugs
- 12,889 ratings averaging 4.5, with 74 per cent of them at five stars
Cons
- Washing it means stripping the bed and unzipping the whole mattress out of it
- 100 per cent polyester, so it sleeps warmer than a cotton or wool top
- A 4 per cent one star tail, mostly zips and sizing
Buy it if you want the most verified protection per pound, or you are dealing with bed bugs. Skip it if you cannot face unzipping a whole encasement to wash it.
The wool one, and the one for a child’s bed
The clean pick
£119.99
3. Woolroom Deluxe Washable Wool Mattress Protector
★★★★☆ 3.6 / 5
This is the only protector here with nothing synthetic against your skin. British wool inside unbleached organic cotton, and an Allergy UK Seal of Approval we confirmed on Allergy UK’s own register rather than taking Woolroom’s word for it. Woolroom also says it holds OEKO-TEX Standard 100 Class 1, though like Panda it publishes no certificate number, so that part we could not check.
Then the miss: it is not waterproof. The company says so in its own FAQ. There is a coated version, but that starts at £189.99.
We would also treat the dust mite marketing carefully. Woolroom says wool is proven to cut dust mite allergens by up to 99 per cent in a six week controlled test, but names no laboratory, university or researcher anywhere on the site, and the wider clinical evidence on mite avoidance in bedding is not encouraging. The wool is lovely. The 99 per cent is a marketing number until someone shows us the study.
The common owner complaint is fit, because there are no securing straps and the skirt wanders. A few report shrinkage at the 40 degree wash the care label allows, while the FAQ on the same website says 30. It scores 4.91 out of 5 from 707 reviews.
Pros
- The wool top layer regulates temperature better than anything else on this page
- Allergy UK verified, and that is one we checked with Allergy UK rather than taking on trust
- 4.91 out of 5 from 707 reviews, the highest average here
Cons
- Not waterproof in any sense, so one spilled drink goes straight through to the mattress
- The care label says 40 degrees and the FAQ on the same website says 30
- Expensive next to protectors that actually protect
Buy it if nothing is ever likely to get spilled in that bed. Skip it if there are children, pets, or a partner who reads with a cup of tea.
Best for a child’s bed
£10.99
4. Caroline Shatuik Waterproof Terry Protector
★★★½☆ 3.3 / 5
£10.99, double.
The cheapest thing here and the one we would put on a child’s bed. A soft terry towelling surface over a membrane backing, a 30cm stretch skirt, and a listing that claims OEKO-TEX certification and vinyl free material. We could not find a certificate number to verify either claim, which is why its honesty score is the lowest in the group. Believe the terry top. Treat the certification as unproven.
It performs, though. It scores 4.5 out of 5 from 11,392 ratings, and the terry surface really does muffle the crinkle that plagues film protectors. The consistent complaint is edge coverage, because the skirt is not sealed, so a large spill can find its way round the side. On a child’s bed, where the job is catching accidents in the middle of the mattress, that is a fair compromise at eleven pounds.
Pros
- £10.99 for a double, the cheapest thing on this page
- Terry towelling over the membrane muffles the crinkle you get from bare film
- A 30cm stretch skirt that fits most standard mattresses
- 4.5 out of 5 from 11,392 ratings
Cons
- The OEKO-TEX and vinyl free claims come with no certificate number we could find anywhere
- The skirt is not sealed, so a large spill can run round the side and reach the mattress
- Nothing published about the fabric beyond the headline description
Buy it for a child’s room or a spare bed. Skip it if you want a claim you can check.
The two we would not buy
Comfort only
Not waterproof
5. Simba Quilted Performance Protector
★★★☆☆ 2.9 / 5
£109, double.
Here is the part that does not make the headline: this protector is not waterproof. There is no membrane in it at all. The published composition is a cotton cover and skirt, cotton filling and a polypropylene lining, and Simba reserves its waterproof TripleShield layer for two other protectors in the range. Three separate independent reviewers poured liquid onto it and watched it go through, one of them within a couple of minutes.
As a comfort layer it is good. Two hundred thread count cotton, 200gsm of fill, silent because there is no film to rustle, and it fits mattresses up to 40cm, deeper than anything else here. If what you want is a washable quilted top layer that makes the bed feel nicer, it does that well.
At £109 it costs eight times the Utopia and protects against less. The 40 degree wash ceiling is a limitation if allergies are the reason you are shopping. Be careful with the review count too: the page shows 4.8 out of 5 from 30,055 reviews, yet Simba’s own bamboo protector shows 30 reviews and the Tencel one 48, so that figure is almost certainly brand-wide rather than this product. We would not read anything into it.
Pros
- Comfortable in a way none of the others are, 200 thread count cotton over a 200gsm fill
- Completely silent, because there is no film in it to crinkle
- Fits mattresses up to 40cm deep
Cons
- It is not waterproof. There is no membrane at all, and three independent reviewers poured liquid straight through it
- £109 for something that adds comfort rather than protection
- Simba’s TripleShield protection belongs to two other products in the range, not to this one
- The headline review count is brand wide. This product on its own has 30
Buy it if you want comfort and have no spill risk. Skip it if you thought you were buying protection.
Last place
No composition published
6. Nectar Mattress Protector
★★★☆☆ 2.8 / 5
£45, double.
Nectar publishes no fibre composition for this protector on its UK site. None. To find out what is in it we had to rely on independent reviewers, who report a Tencel top, a polyurethane film and a polyester skirt. A brand that will not tell you what its product is made of has already lost most of the honesty score. There is a second problem: the OEKO-TEX and Global Recycled Standard claims that circulate online belong to a differently named product on Nectar’s US site and do not apply to what you would receive here.
The product itself is fine and no better than that. It is waterproof, the 90 degree wash ceiling is the highest in the group, and the warranty runs two years. But it cannot be tumble dried, and owners report the film taking well over a day to dry, which is a real problem if it is the only protector you own. Heat is the clearest complaint in Nectar’s own review widget, where one owner simply wrote that it increases heat, and Nectar’s own summary concedes it is very warm to sleep on while the product page sells it on sleeping cool. Depth is 32cm, and Nectar itself warns that 12 per cent of customers order the wrong size.
Pros
- Waterproof, and the 90 degree wash ceiling is the highest on this page
- Two year warranty
Cons
- No fibre composition published on the UK site at all, so you cannot know what is against you
- The OEKO-TEX and Global Recycled Standard claims on the page belong to a differently named US product
- It cannot be tumble dried, which is awkward for something you are meant to wash often
- 32cm depth, and Nectar itself says 12 per cent of orders come in the wrong size
Buy it if you already trust the brand and your mattress is shallow. Skip it if you want to know what you are sleeping on.

The clean pick, and the honest catch
Our clean pick
Woolroom Deluxe Washable Wool
Nothing synthetic against your skin
Why it wins on materials
✓
Nothing synthetic touches you
British wool inside unbleached organic cotton. No film, no coating, no plasticisers anywhere in it.
✓
One seal verified, one claim not
✓
Washable, which wool rarely is
Machine washable at 30 degrees. Most wool bedding is dry clean or spot clean only, which makes it useless as a hygiene layer.
✓
Backed properly
Two year warranty and a 30 night trial. Almost nobody offers a trial on a mattress protector.
What you give up
✕
It is not waterproof
Woolroom says so in its own FAQ. If you need waterproof this is the wrong product, and the coated version starts at £189.99.
✕
It wanders
There are no securing straps, so the skirt slides out of line and needs straightening. This is the most common owner complaint by a distance.
✕
The 99 per cent claim is unsupported
Woolroom says wool cuts dust mite allergens by up to 99 per cent, but names no study, laboratory or researcher. Treat it as marketing.
The catch, said plainly. Our rule is that where a category has a product clean enough that we would happily put it against skin, we name it. Here that is the Woolroom. But it does not stop liquid, and for a lot of households that is the entire reason for buying a protector. If you need waterproof, the right move is a polyurethane or TPU film with third-party certification rather than a PVC or vinyl backing, because vinyl is the layer most likely to carry plasticisers and it is also the noisiest. That is the Panda and the Utopia, which is why they finish level at the top, with the Panda taking the top slot only because a fitted bamboo protector is a nicer thing to lie on than a zipped polyester encasement.
What to look for when you buy one
The film is the whole question. Almost every waterproof protector works by laminating a thin plastic film to the back of a fabric. Polyurethane and TPU are the ones you want. PVC and vinyl are the ones to avoid, because vinyl is the backing most likely to carry plasticisers and it is also, by a mile, the noisiest. Brands that use PU tend to say so. Brands that use vinyl tend to say waterproof and nothing else.
Read the certification carefully. OEKO-TEX Standard 100 on every component is a meaningfully different promise from OEKO-TEX on the face fabric only, and a listing that says certified without a certificate number is a claim, not a fact. Three of the six here show the logo or the words without ever publishing a number, and exactly one, the cheapest on the page, publishes a number that stands up when you look it up. If you take one habit away from this piece, make it that one: search the listing for a certificate number, then check it on the certifier’s own register. It takes a minute.
Check the wash temperature before you check anything else. If dust mites or allergies are the reason you are shopping, you want to be able to wash at 60 degrees. Several protectors on this page cap out at 40, which quietly undoes the point of buying them.
Measure the mattress. Depth is the single biggest cause of returns in this category, and one brand on this page admits that 12 per cent of its customers order the wrong size. Measure from the top of the mattress to the bottom, then buy a skirt deeper than that number.
Waterproof and cool are in tension. Any film traps some heat. A protector can be breathable for a film, but it will never breathe like a bare sheet. Any brand promising waterproof and cool with no qualification is overselling, and the owner reviews will usually tell you so.
Final verdict
Spend £33, not £109
The shape of this category is unusual and worth saying out loud. A £13 encasement from a brand nobody talks about scores level with the £33 favourite, beats everything else on the page, and is the only one of the six that lets you verify its certification instead of asking you to believe it. Meanwhile the £109 Simba does not stop liquid at all, and the £45 Nectar will not tell you what it is made of.
So: the Panda Bamboo for most beds, because it is the nicest thing to sleep on at a sane price. The Utopia if you want the most proof for the least money, or you have a bed bug or odour problem that needs a full encasement. The Woolroom if nothing is ever going to get spilled and you care most about what is against your skin. And keep the receipt on the two expensive ones.
