The best waterproof mattress protectors for 2020
1. The Nectar Mattress Protector
Best waterproof mattress protector
Specifications
Reasons to buy
Reasons to avoid
Why do we like the Nectar Mattress Protector? It's a 100 per cent waterproof, ultra breathable mattress protector that doesn't feel like it. Rather, it's a comfortable mattress protector that just happens to do a great job of being waterproof, too.
What does it do well?
Comfort levels. It's made with Tencel (a material that's extracted from natural wood cellulose and manufactured into a very soft and ultra breathable fabric), which makes it much more absorbent than cotton and cooler than linen. Plus, it's extremely eco-friendly. We like.
Let's talk waterproofing. This is a 100 per cent waterproof mattress protector but that doesn't make it means stiff and plasticky? Instead, it's silky to the touch, quiet and stretchy, too. Plus it's resistant to allergens and dust, making it a good buy for both allergy sufferers and pet owners.
Ease of care?
It's machine washable, as you'd expect from a mattress protector that's inviting spills. And tumble dryer friendly, too.
What else?
The Nectar mattress protector is designed for Nectar mattresses, but it will fit other mattresses. There's a two year warranty on any defects and free delivery, too.
2. Hippychick Fitted Waterproof Mattress Protector
Best waterproof mattress protector for bed wetting: give your own little chicks the comfiest sleep courtesy of this waterproof protector
Specifications
Reasons to buy
Reasons to avoid
This waterproof mattress protector from Hippychick is high quality, discreet and 100 per cent waterproof.
What does it do well?
To be the recipient of a Mother & Baby Gold award, this Hippychick waterproof mattress protector had to be something special, and it is. With its discreet design, it doesn't look or feel as if they’re sleeping on a waterproof cover, while the polyurethane layer that provides the waterproofing is both capable and breathable.
When it comes to the outer layer, it’s an equally breathable brushed cotton, which parents say is enormously comfortable, so no more sweaty nights if your child has been sleeping on plastic water proof sheets that make them hot.
Ease of care
Another thing parents love about this waterproof mattress protector? It can be washed at 60ºC and tumble- or line-dried.
What else to know?
Available as cot and single sheets, as cot sheets and for single beds, too.
3. Tempur Fit Waterproof Mattress Protector
Best waterproof mattress protector for memory foam mattresses: all of the protection, with none of the memory-foam-masking padding
Specifications
Reasons to buy
Reasons to avoid
Not unlike our previous pick, this Tempur Fit waterproof mattress protector's charms lie in its discreet protection and breathability, only scaled up for bigger beds.
Who will it suit?
Perhaps unsurprisingly, this 100% waterproof mattress protector is 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 it's been designed so that you won’t lose out on any of that memory foam mattress goodness beneath. However, it is designed to fit any mattress of up to 30cm deep.
What does it do well?
This waterproof mattress protector is another breathable pick, with the fibre allowing your body heat and moisture to pass through, which helps keep you at an ideal temperature and totally comfortable.
The sheets can be machine washed at 90°C and tumbled dried up to 70°C, too. Perfect for anyone who likes to keep all of their bedding freshly laundered – or for anyone sensitive to dust mite allergies.
What won't you like?
The typical memory foam smell you get when you first open the packaging: it does dissipate but sometimes that takes a couple of days.

4. The Little Green Sheep Waterproof Mattress Protector
Best waterproof mattress protector for prams and moses baskets: forget counting sheep, leave it up to these guys to keep baby’s bed fresh and dry
Specifications
Reasons to buy
Reasons to avoid
Unlike a traditional fitted sheet, which covers all sides of the mattress and clings underneath, this waterproof mattress protector from Little Green flat sheet sits neatly on top, allowing the mattress beneath to breathe from the sides and underneath to keep baby from an over-warm sleep.
What does it do well?
The organic cotton sandwiches an Oeko-Tex Class 1 (Baby) waterproof membrane, absorbing any moisture and wetness rather than letting it pool on the surface.
As well as offering 100 per cent waterproofing and breathability, to keep your baby or toddler dry and cool, whether in a pram, cot or junior bed, this waterproof mattress protector offers an anti-allergy layer to keep dust mites at bay, and is made from luxury cotton for real comfort.
What's more, you can buy this sheet for a Moses basket or carrycot, and it's shaped with oval ends for easy fitting.
What won't you like?
We like the flat sheet feature of this waterproof mattress protector (which means it'll be useful on a play mat or in a car seat, too. But when you have a fidgety toddler, you might want to swap out for a fitted sheet that's guaranteed to stay in place.
5. John Lewis & Partners Specialist Synthetic Waterproof Quilted Mattress Protector
Best waterproof mattress protector for deep mattresses: subtle leak-proofing in a generously-sized, comfortable-feeling package
Specifications
Reasons to buy
Reasons to avoid
An ultra-soft and cooling feel comes courtesy of a poly-cotton blend in this mattress protector from John Lewis & Partners.
What's good about it?
What we like most about this waterproof mattress protector is that 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.
The patented Micro-Fresh® Technology makes it an ideal pick for anyone who likes their bedding to stay fresh – or for anyone with allergies. It's designed to reduce bacteria growth to keep the protector's fabrics 99.9 per cent germ-free.
Who will it suit?
It'll be a favourite pick amongst those who aren't into memory foam: instead, the top is softly quilted, and while it will soften a hard mattress a little, you won't notice much difference to comfort levels on a mattress you're already happy with.
And since it's available in singles as well as larger mattress sizes, it's a safe bet for the whole family.
Ease of care
This waterproof mattress protector is washable up to 40°C; it can't be tumble-dried.
6. Silentnight Waterproof Mattress Protector
Best budget waterproof mattress protector: for waterproofing without the worry
Specifications
Reasons to buy
Reasons to avoid
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 option from Silentnight.
What's it good at?
This waterproof mattress protector is particularly recommended for children, but is available with a deep 30cm skirt and comes in larger sizes, so is a great budget option for spare beds and occasional use.
It’s also fully hypo-allergenic to keep irritating allergic reactions at bay. A great no-frills option.
Ease of care
Like our other simple picks, this waterproof mattress protector is easy to care for; simply pop it into the washing machine at 40°C.
What won't you like?
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. Once it's put on the bed, the strong elastic kept it perfectly in place all night, which will mitigate the rustling.
7. Fogarty Ultimate 3 in 1 Waterproof Mattress Protector
Best hypoallergenic waterproof mattress protector for cots and cot beds: stop sniffles before they start with this anti-allergy mattress cover
Specifications
Reasons to buy
Reasons to avoid
This hypo-allergenic waterproof mattress protector offers peace of mind on two fronts, with its capable waterproofing and seal of approval from the experts at Allergy UK.
What's it good at?
If you’re a new parent who's 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 waterproof mattress protector – and they can sleep easy too.
Reviewers find it durable and well-made, and applauded its waterproofing capabilities which, in addition to the soft Terry towelling cover, make this a great mattress protector for cot beds.
Ease of use
This waterproof mattress protector is fully machine washable, and available in a selection of sizes to fit cot mattress depths up to 14cm.
8. 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
Reasons to buy
Reasons to avoid
This Dreamzie waterproof mattress protector 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.
What's it good at?
Reviewers found that the quality of this waterproof mattress protector belied the bargain price, saying that it fits snugly and stays put, and combines a comfortable soft towelling feel with breathable polyurethane waterproofing.
As you'd expect, the polyurethane membrane blocks 100 per cent of all fluids, sweat, urine and bodily fluids (while letting the mattress breathe). We like that it's thin, so won't mask (but also won't improve) the comfort of your mattress.
Who will it suit?
New parents or parents of children who suffer from allergies will like that the Bi-Ome treatment offers protection against common allergens, such as dust mites, bacteria, mould and pollen. That said, since it's available in larger mattress sizes, it'll suit allergy-prone adults, too.
It also comes with OEKO-TEX certification, which means there are no traces of toxic products within it.
Ease of care
This waterproof mattress protector comes as a fitted sheet with large flaps adaptable for mattresses up to 15cm; it's machine washable up to 60°C and can go in on low-temperature drying cycles.
9. Staydrynights Quilted Waterproof Mattress Protector
Best waterproof mattress protector for comfort: sumptuously quilted, satisfyingly dry
Specifications
Reasons to buy
Reasons to avoid
This Staydrynights Quilted waterproof mattress protector is available in a choice of sizes, has a cover crafted from soft durable polycotton and is quilted for added comfort.
What's it good at?
Its soft cotton cover is popular, and it belies the waterproof reverse hidden beneath. Reviewers like its fit and quality, saying that it sits snugly on all mattress sizes with no annoying excess material (a downside with waterproof mattress protectors because it adds to the 'rustling' noise you get with too much material).
It was also commended for its luxuriously soft feel and comfortable quilting, beating thinner protectors hands-down for quality, despite its low price.
Ease of use
It is machine washable and will fit mattresses up to 30cm deep.
What's it not good at?
It air dries slowly because of its heft, and it can't go in the dishwasher; at least one reviewer invested in a second waterproof mattress protector, as a back up, but you'll need to consider how much storage space you have or whether a thinner or tumble-dry option might be better.
