The best waterproof mattress protectors

‘Oops’ moments are always going to happen, but you can get your damage control in ahead of time with our pick of the best waterproof mattress protectors for everything from cot beds to super kings

TODO alt text

We’re all well aware of the importance of a good night's sleep, and the big part that our mattresses have to play in achieving it, but when the best mattresses for our bad backs and tricky knees can cost easily into four figures, it makes sense to look after them – the best waterproof mattress protectors are a good place to start. 

Whether it’s perspiration, leaks or the odd cup of tea, a waterproof mattress protector can be very valuable in preventing liquids getting through to your mattress, keeping it fresh and hygienic, and allowing you to stay comfortable enough to sleep through the night.

For big beds, our top pick is the Tempur Fit Mattress Protector, which wins the day with its naturally breathable cotton construction and discreet design. For smalls, it’s the Hippychick Fitted Mattress Protector, which comes in single and cot bed sizes, or the Dreamzie Waterproof Mattress Protector for sizes from toddler up to super king. 

The best waterproof mattress protector

1. Hippychick Fitted Mattress Protector

Give your own little chicks the comfiest sleep courtesy of this waterproof protector

Specifications
Best for: Kids
Size: Cot, single
Material: Cotton
Quilted?: No
Reasons to buy
+ Can be machine washed and tumble-dried 

To be the recipient of a Mother & Baby Gold award, this Hippychick mattress protector had to be something special, and it is. With its discreet design, the desired effect is that it won’t look or feel as if they’re sleeping on a waterproof cover, and the polyurethane layer that provides the waterproofing is both capable and breathable. When it comes to the outer, there’s equally breathable brushed cotton, which parents say is enormously comfortable, loving its ability to be washed at 60ºC and tumble- or line-dried. 

Tempur Fit Mattress Protector

2. Tempur Fit Mattress Protector

All of the protection, with none of the memory-foam-masking padding

Specifications
Best for: Memory foam mattresses
Size: Small single, single, double, king, super king
Material: Tencel, polyurethane
Quilted?: No
Reasons to buy
+ Fine dry layer lets you feel the benefit of your mattress 

Not unlike our previous Hippychick pick, this Tempur mattress protector’s charms lie in its discreet protection and breathability, only scaled up for bigger beds. Perhaps unsurprisingly, it’s ideal for use with Tempur mattresses, not only because the intelligent polyurethane membrane keeps any errant moisture away from your high-end mattress without sacrificing comfort, but also because the relative thinness of the protector means you won’t lose out on any of that memory foam goodness, combining support and dryness admirably. 

The Little Green Sheep Waterproof Mattress Protector

3. The Little Green Sheep Waterproof Mattress Protector

Forget counting sheep: leave it up to these guys to keep baby’s bed fresh and dry

Specifications
Best for: Softness
Size: Carry cot, cot bed, crib, junior bed
Material: Cotton
Quilted?: No
Reasons to buy
+ Flat sheet allows sides of mattress to breathe 

Unlike a traditional fitted sheet, which covers all sides of the mattress and clings underneath, this flat sheet sits neatly on top, allowing the mattress to breathe from the sides and underneath to keep baby from an over-warm sleep. As well as waterproofing and breathability, this cot bed mattress protector from The Little Green Sheep offers an anti-allergy layer to keep dust mites at bay, and is made from breathable and absorbent luxury cotton for the utmost comfort. 

John Lewis Specialist Quilted Mattress Protector

4. John Lewis Specialist Quilted Mattress Protector

Subtle leak-proofing in a generously-sized, comfortable-feeling package

Specifications
Best for: Deep mattresses
Size: Single, double, king, super king
Material: Poly
Quilted?: Yes
Reasons to buy
+ Suitable for deep mattresses 

An ultra-soft and cooling feel comes courtesy of a poly-cotton blend in this waterproof bed cover, and best of all, it doesn’t look or feel anything like the crinkly, sweaty plastic sheets that haunt our thoughts when we summon up images of waterproof bedding. It’s earned hundreds of positive reviews for its amazing leak-proofing, thanks again to good old polyurethane membrane, but the difference between this one and previous picks lies in its ability to cover deep-sided mattresses for all-round protection. 

Silentnight Waterproof Mattress Protector

5. Silentnight Waterproof Mattress Protector

A budget mattress protector for waterproofing without the worry

Specifications
Best for: Budgets
Size: Single, double, king
Material: Polypropylene
Quilted?: No
Reasons to buy
+ Stays in place all night 

Those on a tight budget will be glad to find that there are some top-value options among our best sheets for bedwetting, like this one from Silentnight. Compared to some higher-end options, users did report it rustled a little when moving about, but found this tended to disappear after a wash, and once it was put on the strong elastic kept it perfectly in place all night. It’s also fully hypo-allergenic to keep irritating reactions at bay. A great no-frills option.

Fogarty Ultimate 3 in 1 Waterproof Mattress Protector

6. Fogarty Ultimate 3 in 1 Waterproof Mattress Protector

Stop sniffles before they start with this anti-allergy mattress cover

Specifications
Best for: Hypoallergenic
Size: Cot
Material: Cotton, polyurethane
Quilted?: No
Reasons to buy
+ Certified hypoallergenic and dust mite-resistant 

This hypo-allergenic mattress protector offers peace of mind on two fronts, with its capable waterproofing and seal of approval from the experts at Allergy UK. If you’re worried about bed bugs, dust mites or any other allergens that might leave little ones with nasty itches or sniffles, you can rest assured with this one, and they can sleep easy too. Users found it durable and well-made, and applauded its waterproofing capabilities which, in addition to the soft cotton cover, make this a great mattress protector for cot beds. 

Dreamzie Waterproof Mattress Protector

7. Dreamzie Waterproof Mattress Protector

Odd-sized mattress? No fear, this Dreamzie protector works for every member of the family from the smallest to the biggest

Specifications
Best for: One for everyone
Size: Toddler, single, small double, double, European double, king, European king, super king
Material: Polyurethane, cotton
Quilted?: No
Reasons to buy
+ Huge range of sizes 

This waterproof mattress topper from Dreamzie isn’t just reasonably priced, it also comes in every single mattress size you can think of – European and UK sizes included – from toddler upwards, so it’s a one-stop shop if you need to get a few. Users found that the quality of this protector belied the bargain price, saying that it fits snugly and stays put, and combines a comfortable soft towelling feel with breathable polyurethane waterproofing in a discreetly designed package. 

Staydrynights Quilted Mattress Protector

8. Staydrynights Quilted Mattress Protector

Sumptuously quilted, satisfyingly dry

Specifications
Best for: Fit
Size: Single, double, king
Material: Cotton, polyester, vinyl
Quilted?: Yes
Reasons to buy
+ Fit snugly; no excess material 

Users were delighted with the fit and quality of this mattress protector, saying that it sat snugly on all mattress sizes with no annoying excess material, and that it beat thinner protectors they’d previously tried hands-down. It was commended for its luxuriously soft feel and comfortable quilting, but the only potential issue some spotted was that it couldn’t be tumble-dried, so if the weather’s too cold and damp for proper air-drying, you might want to consider investing in a backup. 

Bloom Universal Mattress Protector

9. Bloom Universal Mattress Protector

This cotton mattress protector keeps going and going, and suits all sizes

Specifications
Best for: Flat sheet
Size: Universal
Material: Cotton
Quilted?: No
Reasons to buy
+ Washes beautifully; maintains quality 

Like our Little Green Sheep crib mattress protector, this offering from Bloom is a flat sheet rather than a fitted sheet, forming a layer between the mattress and your upper sheet to stop any spills getting through. Users were very impressed with the quality of the fabric, a supremely soft cotton flannel, saying that it stood up beautifully to washing and didn’t present any unsightly pilling. They also found that it stayed put during the night, so if you’re worried about a flat sheet being less stable, don’t be discouraged just yet.
