The best mattress protectors are a great way to help you sleep even more soundly, Not only will they safeguard your mattress against dirt, spills and allergens, they can also provide a welcome extra layer of comfort. Without a mattress protector, even the best mattresses can quickly fall into a bad condition; however with an extra layer of protection they'll remain fresh, clean and in good condition for much longer. And at the end of the day it's much cheaper to buy a new mattress protector than having to spring for a whole new mattress.

Here we've gathered together a selection of the best mattress protectors for all budgets and bed sizes, in one handy place. That said, if your mattress is already past its peak (and you can't stretch to a new one), you might be better picking up one of the best mattress toppers instead.

The best mattress protector overall

Specifications

Size: Small single, single, double, king, super king
Material: Tencel, polyurethane
Quilted: No
Waterproof: Yes
Reasons to buy
+Breathable, absorbent Tencel+Waterproofing without discomfort+Can be tumble dried 
Reasons to avoid
-Not the cheapest

The words “waterproof mattress protector” might summon up images of crinkly plastic sheets, but the Tempur Fit Mattress Protector is an ultra-thin, breathable, cotton mattress protector that puts paid to that idea straight away. Rather than employing a sweaty plastic layer to deal with spills and leaks, it uses a smart polyurethane membrane in conjunction with a breathable, absorbent Tencel surface layer to keep things dry, comfortable and undamaged. 

Ideal for use with Tempur memory foam mattresses – but suitable for any single, double, king or king size mattress with a depth of 21-27cm – it has an easy stretch design and deep sides to cover all eventualities. Feeling lazy? You can choose to sleep on it directly – like a sheet – or underneath your favourite bed sheets, as usual. It can also be machine washed at up to 90C (and tumble dried up to 70C), while a three-year guarantee gives you long-term peace of mind. We think that for the money, the Tempur Fir Mattress Protector is the best mattress protector right now.

A luxurious mattress protector from a premium brand

Specifications
Size: Single, double, king, super king
Material: Microfibre and modal
Quilted: No
Waterproof: No
Reasons to buy
+Thermoregulating fibre+Hypoallergenic

Brook + Wilde specialises in luxurious mattresses with price tags to match, so it's surprising to see that its own mattress protector doesn't cost a lot more. Who's complaining, though? 

This one's all about keeping you cool and refreshed at night; it's filled with a mix of thermoregulating microfibre and Modal, with a cover made of textured, breathable microfibre, and it's designed to fit snugly onto any Brook + Wilde mattress. It's hypoallergenic and washable at 60 degrees, and you can pop it in the tumble dryer safely.

3. Nectar Mattress Protector

The best mattress protector for preventing overheating

Specifications
Size: Single, small double, double, king, super king
Material: Tencel jersey and polyester
Quilted: No
Waterproof: Yes
Reasons to buy
+100% waterproof+Eco choice+Good if you get hot at night
Reasons to avoid
-Only returnable if unopened or faulty

Like the Tempur above, the Nectar Mattress Protector is made from Tencel – a material extracted from natural wood cellulose and manufactured into a very soft and ultra breathable fabric. That makes this temperature-regulating mattress protector great for anyone who tends to overheat at night. More absorbent than cotton, and softer and cooler than linen, Tencel is extremely eco-friendly, and the makers claim it's a 100% waterproof mattress protector. It certainly seemed to take what we threw at it with ease, although we have to confess that with no toddlers in the house, we possibly didn’t test it to the limit. Either way, if you tend to overheat, the Nectar mattress protector is a particularly fine choice.

4. Simba Mattress Protector

A flexible and environmentally friendly option

Specifications
Size: Single, double, king, super king
Material: Tencel and polyester
Quilted: No
Waterproof: Yes
Reasons to buy
+Eco-friendly+Waterproof

Simba's mattress protector is designed to fit perfectly on Simba's own hybrid mattresses, unsurprisingly, but if you don't have a Simba mattress you'll find that it should be flexible enough to fit on your bed anyway. 

It's made from sustainable Tencel fabric, which is softer than cotton and won't keep you awake with unseemly rustling, and it features a polyurethane layer to provide protection from dirt, moisture, stains and spillages. It's also OEKO TEX 100 certified, so contains no harmful chemicals, and while it's a bit pricier than many of the mattress protectors listed here, its advanced features are worth paying a bit more for.

5. Emma Mattress Protector

A lot of protection from our favourite mattress brand, but with a price to match

Specifications
Size: Single, small double, double, king, super king
Material: Polyester
Quilted: No
Waterproof: Yes
Reasons to buy
+100% waterproof+Allergen-resistant
Reasons to avoid
-Expensive

Emma's mattress protector isn't just a little more expensive than most of the other options here; it's quite a lot more expensive, with even the single coming in at just under £90. However, Emma promises that it'll provide the maximum protection for any mattresses, and seeing as how the Emma Original is our top-ranked mattress right now, it's a claim you have to take seriously.

The Emma mattress protector features a 100% waterproof EmmaGuard layer that protects your mattress from spills, crumbs and anything else that might mess up your bed, and it's made with an AllergyShield technology that's clinically proven to protect you from dust mites and pet hair allergens. Best of all it's thoroughly breathable and crinkle-free; whether that's enough to justify the price is entirely up to you.

A clinically useful mattress protector doesn’t always have to look like one. This geometric quilted mattress protector from The White Company wouldn’t look out of place in a luxury hotel, so if you’re big on Insta-ready roomscapes, but not so big on bed bugs, you might want to take a look at something like this. The pure cotton mattress cover is filled with plush layers for comfort, and finished off with a hygiene treatment to stop dust mites and bacteria from settling, making it our best mattress protector for allergy sufferers.

7. Purple Mattress Protector

Advanced spill protection makes this worth the price tag

Specifications
Size: Twin, twin XL, full, queen, king, Cal king
Material: Polyester, Spandex and polyurethane
Quilted: No
Waterproof: Water-resistant
Reasons to buy
+Dual-layer spill protection+Stain-resistant
Reasons to avoid
-Expensive

Another mattress protector from the pricier end of the market, this one from Purple has a stack of positive reviews suggesting that it's well worth the extra expense. Its headline feature is its dual-layer spill protection that not only prevents spills from soaking through into your mattress, but also dissipates them so they don't create a puddle if you're exceptionally clumsy with your bedside glass of water.

As well as protecting your mattress from whatever you care to throw at it, the Purple mattress protector is also stain-resistant and machine-washable, making it nice and easy to keep clean.

Sizes: Single, Double, Kingsize, Super Kingsize
Material: Polyester, polypropylene, hollowfibre
Quilted: Yes
Waterproof: No
Reasons to buy
+Smooth feel+Low price+Easy fitting
Reasons to avoid
-Not the highest quality materials

This quilted mattress protector feels luxuriously smooth and silky to the touch, so the low price (just £16 at time of writing) came as quite a surprise to us. The Fogarty Soft Touch Mattress Protector is lovely in use too: embossed with a microfibre cover, it's filled with hollowfibre for added comfort and has elasticated corners for easy fitting. It's also machine washable, suitable for mattresses up to 30cm deep, and a deeper 35cm option is also available. Overall, then, although this isn't the highest quality mattress protector on our list, particularly in terms of the materials used, it's certainly a great option if you're counting the pennies.

9. Tuft & Needle Mattress Protector

Material: Polyester and Spandex
Quilted: No
Waterproof: Water resistant
Reasons to buy
+Fits most mattresses+Soft and quiet cover
Reasons to avoid

We don't know about you, but seeing that a mattress protector is water resistant rather than waterproof sets alarm bells ringing for us. Just how water resistant is it? Looking through the reviews for Casper's water resistant mattress protector, though, should set your mind at rest; it seems it'll cope well with whatever you care to spill on it.

If you have a Casper mattress and find its cover a little rough, this mattress protector should soften the experience up nicely. And even if you don't have a Casper mattress, this protector should still fit well; it features elastic skirting with a 360 degree grip, and will fit any mattress up to 16 inches deep.

This oh-so-soft mattress protector for crib mattresses is made from a breathable, extra absorbent cotton, creating a sleeping environment for your child that’s both dry and comforting.

The Little Green Sheep Organic Waterproof Crib Mattress Protector is also machine-washable, tumble dryer-safe and best of all, light on noisy crinkling, however much your little one tosses and turns.

A great way to keep your mattress dry, clean and fresh

Waterproof: Moisture protection
Reasons to buy
+Five-sided moisture protection+Anti-microbial treatment+Easy to wash

Depending on the size you choose it'll fit any mattress up to 17.5 inches thick (smaller options don't go quite so deep, and it's easy to look after; just throw it in the washer and dryer on a hot setting.

One thing to bear in mind is that Leesa recommends giving its mattress protector a wash before you use it, which it says will help reduce any noise. The last thing you want is to be kept up all night by a crinkly mattress protector, right?

14. Slumberdown Teflon mattress protector

The best mattress protector made using Teflon

Specifications
Best for: Easy care
Sizes: Single, double, king
Material: Teflon, polyester
Quilted: Yes
Waterproof: No
Reasons to buy
+Great value+Reinforced elasticated straps+Machine and tumble dryer friendly
Reasons to avoid
-Not suitable for mattresses deeper than 30cm

You might be forgiven for thinking that a Teflon coating is just for frying pans, but in this case it serves to protect your mattress – old or new – from sweat, pets and occasional spills. Although the Slumberdown Teflon mattress protector is more water resistant than waterproof, it does ensure that small spills run off rather than soak in, and can be quickly wiped to prevent leakage and staining of the mattress below. The outer is soft to the touch, it's machine washable and it can be popped into a tumble dryer too; so even if it does have to cope with the worst, it can be quickly cleaned and put back on the bed within a few hours. And all this for a very reasonable price indeed.

15. Panda Eco mattress protector

The best mattress protector for sensitive skin or eczema

Specifications
Best for: Sensitive skin
Size: EU single, EU double, EU king, emperor, twin, UK double, UK king, UK super king
Material: Cotton and bamboo rayon mix
Quilted: No

Reasons to buy
+Regulates nighttime temperature+Machine washable and suitable for tumble-drying+Two-year guarantee
Reasons to avoid

Created from a blend of bamboo rayon and cotton, the Panda Bamboo Mattress Protector is a durable, breathable mattress protector. It's hypoallergenic, naturally antibacterial, and tested and certified by OEKO-TEX Standard 100, meaning it’s resistant to mould, fungi, mildew and dust mites. It draws out moisture too, so as well as being a great choice for the more eco-minded – bamboo rayon takes a third less water to produce than cotton – it’s also good for people who overheat at night. The waterproof layer is thin and light and, more importantly we feel, doesn’t produce a nasty crinkling sound when you lie on it.

Sizes: Single, double king, super king
Material: Microfibre outer, DuPont fibre interior
Quilted: Yes
Waterproof: No
Reasons to buy
+Soft exterior+Springy inside+Hypoallergenic
Reasons to avoid
-Won’t fit deeper mattresses

The neat parallel-line quilting of the Sealy Balance mattress protector ensures the filling of smooth, silk-like springy Serica fibre stays evenly distributed inside. This gives you a balanced, relaxed and comfortable night, while at the same time protecting your mattress from minor spills. The elastic straps aren’t the most robust we encountered, which might not make it the best choice for extra deep mattresses. But they did keep the protector in place even for the most restless of sleepers.

Also, its dimensions means this one is recommended for very thick, deep-sided mattresses that are often stumped by regular bedding. If that's what you have, this is the best mattress protector for you.

The fit and quality are high, it can be machine washed at 40˚C, and it carries a two-year guarantee.
