1. Marks & Spencer Quilted Waterproof Mattress Protector

The best waterproof mattress protector (that doesn't rustle)


RRP: From £35
Sizes: Single / Double / King / Super King
Material: Cotton outer, polypropylene reverse, polyester filling
Care : Machine wash at 40°c, tumble dry low temperature

Reasons to buy

Discrete without any rustle
Quilted for additional comfort
Can be machine washed and tumble dried on a low temperature

Reasons to avoid

There are cheaper options available

Whilst opting for a waterproof mattress protector is the best way to protect your mattress from all eventualities, no one wants their sleep disturbed by the crinkle and rustle that tends to accompany a waterproof layer.

This quilted option from Marks & Spencers delivers the best of both worlds, with a cotton outer and quilted polyester fill upper, and a water-resistant polypropylene reverse for discrete protection.

The biggest plus points are that our tester found this waterproof protector to be virtually silent when on the bed – no matter the amount of tossing and turning they did! And, unlike many waterproof mattress protectors, this design can also be machine washed and tumble dried, albeit at 40°c and on a low-temperature tumble dry. Still, we'll take all the convenience we can get when it comes to laundry day!

It's also relatively affordable, fits the bed well, washes well, and repelled moisture well whilst providing a comfortable sleep surface. Our only niggle is that our hotter sleepers did find the synthetic fill a little less breathable than a cotton or wool-filled option, and those manmade fibres aren't the gentlest on the planet, being made from non-renewable resources and unable to biodegrade at the end of the protector's lifespan. 

That said, if you're after waterproofing, then adding this mattress protector to your bed is certainly going to prolong the lifespan of your mattress, and offer a very welcome, stress-free sleep.

5. Woolroom Chatsworth Washable Wool Mattress Protector

The best temperature-regulating mattress protector


RRP: From £129.99
Sizes: Single / Double / King / Super King / Emperor
Material: Organic cotton and British wool
Care : Machine wash with wool detergent, do not tumble dry

Reasons to buy

Temperature-regulating and eliminated night-sweats
Naturally hypoallergenic, only natural protector to hold the Allergy UK Seal of Approval
Made from renewable and biodegradable materials
No rustle

Reasons to avoid

An investment
Needs a little extra care when washed

If you're looking for a cooling mattress protector then Woolroom's Chatsworth Washable Wool Mattress Protector is our top recommendation.

Overheating at night can often be down to the materials your mattress is made from, especially if yours has a memory foam, latex, or synthetic foam top layer. Made of plastic polymers, synthetics aren’t breathable so the natural heat and moisture our bodies emit overnight is reflected back towards us and can lead to overheating.

In contrast, wool does a great job of regulating temperature – perhaps no surprise seeing as a sheep's temperature-regulating fleece keeps it warm in the winter and cool in summer! – so adding a layer of wool between your body and your synthetic mattress can really help breathability.

Made from unbleached organic cotton with quilted, wool-filled padding, Woolroom's Chatsworth Washable Wool mattress protector helps to combat night sweats and keep you at a steady temperature all night long – meaning a better chance of a deeper, uninterrupted, and restorative sleep. In fact the brand states it will eliminate up to 70% of body heat compared with a synthetic option, and this was definitely borne out in our testing, with our usually hot sleepers noticing immediate improvements when they added this breathable sleep surface to their memory foam and synthetic mattresses.

The all-natural materials used are also a welcome change from the usual synthetics, being both renewable and biodegradable and therefore much gentler on the planet – although it did take us a while to adjust to the unbleached look as opposed to the usual (far less eco-friendly) bleached brilliant white. Naturally hypoallergenic, this protector is also certified by Allergy UK as the only natural protector to hold the Allergy UK Seal of Approval.

The downsides? Although this mattress protector is machine washable, you'll need to use a wool wash and avoid tumble-drying, so it's not as easy to care for as a synthetic option that can be bunged in the machine at 60°c. And it is an investment. Although if you're struggling to sleep because of overheating, we think that's an investment in your well-being well worth making.

9. Fogarty Soft Touch Mattress Protector

The most affordable mattress protector


RRP: From £15
Sizes: Single / Double / King / Super King
Material: Polyester outer, polypropylene reverse, recycled polyester filling
Care : Machine washable, tumble dry low temperature

Reasons to buy

Washes well
Elasticated skirt
Made of recycled fibres

Reasons to avoid

Synthetic fill isn't as breathable as a natural-fill option

If you don't need your mattress protector to be waterproof, and you're happy to opt for synthetic materials rather than more breathable (yet more expensive) natural fibres, then we'd suggest you don't need to spend a fortune on a mattress protector.

Opting for an affordable mattress protector will still do a fine job of adding an extra layer of protection between your sheet and your mattress. Although there are a few things worth looking out for in order to ensure your purchase is the best value – after all, there's no point in buying the cheapest mattress protector available if it's going to shrink in the wash, rip, or need replacing it in a few months' time.

The Fogarty Soft Touch Mattress Protector isn't the cheapest on the market, but we think it ticks all the boxes in terms of value. Firstly, unlike most cheaper options we've come across, it comes with a fitted skirt to secure it to the mattress rather than elasticated straps, which we think gives your bed a nicer finish and a more secure fit. 

Secondly, the microfibre cover is satiny and soft to the touch giving it a little extra luxe, and the hollowfibre fill adds a small but not insignificant amount of cushioning. 

It also washes well and that hollowfibre fill is made from certified recycled polyester from waste, like plastic bottles or manufacturing off-cuts. As the brand states 'recycled polyester helps the movement towards a more circular economy, reducing waste going to landfill. Compared with virgin polyester, recycled polyester helps conserve crude oil reserves during fibre production'. Not bad considering there are plenty of far more expensive options that aren't doing their bit for the planet, so all in all, it's a thumbs up from us.

How to choose a mattress protector 

To narrow down your choices, you should start by deciding if you need full waterproof protection - if you don't, a cotton or polyester protector will be more breathable. Then think about comfort. Mattress protectors are not the same as mattress toppers when it comes to boosting comfort levels but if your existing mattress could benefit from a little extra cushioning, check out the quilted designs with padding. Finally, it comes down to individual needs, like cooling or allergy relief, but if neither affects you, we’d recommend choosing the best mattress protector for you based on your budget.  Oh - and of course check the size of your bed. A mattress protector of the wrong size will struggle to cover all basis. 

Additionally, Karen Innes, NPD Manager at Slumberdown adds: 'Something often overlooked is washing your bedding, and your mattress protector is no exception - choose a mattress protector that is machine washable and try to get into a washing routine with your bedding to prevent any build-up of sweat, oil and dirt.'

Should you choose a mattress protector or a mattress topper?

Steve Reid, CEO at Simba offers his advice: 'If your mattress is genuinely uncomfortable a mattress topper won’t solve the problem for long, if at all. While it might smooth out immediate lumps and bumps caused by old springs, it’s unlikely to offer extra support to sagging beds, and furthermore can trap heat and make your bed uncomfortably warm. They’re a great short-term solution, but the only way to fix your bed is to buy a new mattress. 

A mattress protector, on the other hand, is something that everyone should ideally have. They help keep your mattress clean and hygienic.'

Do mattress protectors make a difference?

A mattress protector may seem like an unnecessary add-on. But they’ll do wonders for keeping your mattress guarded from spills, damages and dirt that may seep through your sheet (even without you realising). Ever noticed some marks or yellow stains on your mattress, but unsure where they’ve come from? Yep, a mattress protector will take the stain instead, leaving your mattress fresh underneath. This all contributes to the longevity of your, fairly expensive, mattress. 

How often should you wash a mattress protector?

Mattress protectors are there to care for your mattress, by guarding it against dust mites, debris, stains and spills. In order for it to do so, your mattress protector needs a little TLC itself. It’s recommended you wash your mattress protector every two months or so, providing no spillages occur in the meantime. How you wash will depend on the type of protector and the material it’s made from. Waterproof mattress protectors can’t often be put in the washing machine and delicate fibres like wool shouldn't be tumble dried. In short: refer to the care instructions before washing. Ultimately, if you care for your mattress protector it’ll look after you and your mattress too.
