The best mattress protectors to help keep your bed clean and comfy

When investing in better sleep, most of us focus on the big stuff - a supportive mattress, cloud-like pillows and a dreamy duvet set. But there's one bedroom essential that often gets overlooked, and it's arguably just as important: a mattress protector.

It might not be the most exciting buy, but a mattress protector works quietly behind the scenes to keep beds cleaner, comfier and last longer. It's a thin layer between your sheets and mattress, acting like a shield - protecting mattresses from spills, sweat, dead skin cells, and even the odd breakfast-in-bed mishap.

Over time, all these things can stain or damage your mattress, and considering how pricey a new one can be, it makes total sense to safeguard the one you've got. Not only does a protector keep things more hygienic, but it can also extend the life of your mattress, which is essential for your sleep and your purse strings.

When shopping for a mattress protector, remember a few things. Firstly, think about size - it goes without saying that you'll need to buy one that matches your mattress (single, double, etc.).

It's also worth considering materials. Cotton is breathable and soft, which is great for everyday use, or you could opt for a waterproof protector - ideal for kids or if you're worried about spills. There are also cooling protectors made with moisture-wicking fabrics, such as polyester and bamboo, for hot sleepers.

Some protectors are treated to reduce allergens like dust mites, making them ideal for allergy sufferers or anyone with sensitive skin. If you're a light sleeper, look for a quiet protector that won't rustle every time you roll over - especially important with waterproof designs.

It really depends on what you're after, but it's worth noting that a mattress protector and topper do two very different jobs. A protector is designed to shield your mattress from everyday wear and tear, while a topper is all about comfort. It's thicker, often padded, and meant to change your mattress's feel, whether adding extra softness or firming things up a bit.

Just like your sheets, a mattress protector needs regular cleaning. Aim to wash it every one to two months, or more frequently if you have allergies or pets. Always check the care label, though - some protectors are machine washable, while others may have specific instructions to preserve waterproof layers or special coatings.

This waterproof protector has received glowing reviews from Dunelm shoppers, who praise its ability to withstand spills and nighttime mishaps. One reviewer said it's been a game changer for her husband, who suffers from night sweats, while another shared that it saved their mattress after their dog had an accident - proof that it's as practical as it is protective.

Made from a breathable polycotton blend, it offers the softness of cotton with the durability of polyester, meaning it's both comfortable and easy to care for. The quilted top adds a layer of bounce and cushioning, while the waterproof polyurethane backing works hard to block moisture and keep the mattress in great condition.

As mentioned, the reviews are mostly positive, with one person saying: "Brilliant mattress protector. The second one was brought due to new bedding, and the spare works and doesn't make a noise. Washes nicely. Had blood on and came straight out without needing to use stain remover. The best one I have ever had is deep enough for a thick mattress."

But someone else piped up: "The quilt slips and slides, cue massive rustling. And no, tucking it in tight around the mattress didn't solve it either. My search for a silent, waterproof mattress protector goes on."

Sizes available: Single, small double, double, king, super king

Material: Cotton, polyester, recycled polyester, vinyl

Waterproof? Yes

Machine washable? Yes

You might think of mattress protectors as the thinner cousin of mattress toppers - but some come with a little extra bounce. Deep fill has the benefits of adding a little extra comfort, as well as protection, with just enough plushness to refresh the bed without the bulk of a full topper.

This one, by The Fine Bedding Company, is proof that practical can still feel luxurious. Crafted from a deep fill and a soft cotton blend, it features a quilted finish that adds gentle cushioning without overwhelming the mattress. The smooth cotton casing boosts breathability, helping to regulate temperature for a cooler, more comfortable night's sleep.

One reviewer said: "This is a lovely deep mattress protector, easily fitted the mattress but would also have easily fitted a deeper one. Lovely quality. Very pleased." However, someone else complained it was 'overpriced' for what it is.

Sizes available: Single, double, king, super king

Material: Cotton, polyester fibres

Waterproof? No

Machine washable? Yes

Quality bedding can sometimes cost a small fortune, as some of the premium picks on our list prove, but Silentnight shows that comfort doesn't have to come at a steep price. This anti-allergy protector starts at £19, with larger sizes currently discounted on Amazon; it's a solid choice for anyone after reliable, budget-friendly bedding.

Designed with elasticated corner straps to keep it firmly in place, it's also filled with anti-allergy fibres, making it an excellent option for sensitive skin or dust allergies. It also has a two-year guarantee for peace of mind.

In terms of feedback, one five-star review reads: "Great lightweight item. The sizing is perfect, and the straps are a great size and fit my super deep mattress beautifully. It's soft and a great value for money." However, someone else complained: "Very thin and flimsy. I wouldn't pay more than £5 if I were to buy again."

Sizes available: Single, double, king, super king

Material: Cotton, microfibre

Waterproof: No

Plenty of mattress protectors claim to be hypoallergenic, often using materials like bamboo to keep dust mites at bay. But Simba has taken an innovative approach.

This protector features a cutting-edge, wash-resistant treatment that actively deters dust mites and helps reduce allergens that can disrupt sleep without relying on synthetic chemicals. Instead, it uses a natural extract from the margosa plant, native to Southeast Asia.

Combined with breathable cotton and a 200gm cotton fill, it strikes the ideal balance between protection and comfort, promoting airflow while adding a touch of cushioned softness. As with all Simba products, it's available in a wider range of sizes than most, including the often-overlooked small double, so buyers are more likely to find the perfect fit.

Customer reviews give it a strong 4.8-star rating, with one person saying, "It fits perfectly over the mattress and stays in place without bunching up." However, another shopper noted, "It's okay, nothing special."

Sizes available: Single, small double, double, king, super king. Also available in EU sizes

Material: Cotton, polypropylene

Waterproof? No

Machine washable? Yes

The warmer months are officially upon us - even if the British weather hasn't quite made up its mind - which makes now a smart time to invest in cooling bedding. Tempur's cooling range stands out for good reason (our review of the brand's cooling memory foam pillows is here), and this mattress protector is no exception.

It's made with a soft, breathable Tencel cover and clever microcapsule technology that helps regulate temperature throughout the night. Unlike typical protectors that use elasticated straps, this one fits like a fitted sheet for a sleeker, more secure feel. It's also waterproof and anti-allergy, protecting against spills, dust mites and more.

Feedback-wise, one person praised it as 'an excellent product and quality service from Feather & Black (the supplier).' However, someone via John Lewis noted: "During the night, the cover completely comes away from the side."

Sizes available: Single, double, king, super king

Material: Lyocell, polyurethane

Waterproof? Yes

Machine washable? Yes

Here's something a little different - the Jay-Be mattress protector offers full 360-degree coverage thanks to its zip-around design. Instead of just sitting on top like a fitted sheet, this protector completely encases the mattress, offering added peace of mind against spills, dust mites, and allergens.

The zip-on structure makes it easier to secure tightly around the mattress, although we wonder how effortless it is to take on and off, especially when washing. It's only available in a single size, so anything larger might be more challenging to handle.

It's fully waterproof and hypoallergenic, so it's a smart choice for kids' beds or anyone with sensitive skin. Plus, it comes with a one-year guarantee for added reassurance.

There aren't any reviews online - as mentioned, our only potential gripe is the ease of taking it on and off.

Sizes available: Single (80cm)

Material: Not specified

Waterproof? Yes

Machine washable? Yes

It's not just your mattress that deserves protection—your pillows do, too. While many brands stop at mattress protectors, Soak & Sleep goes one step further with a smart bundle that includes a mattress protector and two matching pillow protectors, making it easier to protect bedding from sweat and spills, all in one purchase.

The protectors are crafted from soft, breathable cotton that naturally wicks away moisture - ideal for hot sleepers and warmer nights. A protective polyester lining adds an extra barrier without compromising comfort, while the quilted finish lends a luxurious, cushioned feel.

Shoppers can choose between a standard or deeper mattress protector, which is designed for a mattress with extra height so you don't have to wrestle with ill-fitting corners. The pillow protectors come with zipped closures to ensure a snug, secure fit that stays in place night after night.

One shopper said the mattress protector is 'very good quality', while another said it's 'easy to fit.' However, a disappointed reviewer said: "(The protector) is part polyester, so it feels much too warm compared with a wholly cotton one."

Sizes available: Single, double, king, super king

Material: Cotton, polyester

Waterproof? No

Machine washable? Yes
