The best mattress protector will keep your bed feeling fresh, clean, and free from spills. Whether you've just bought the best mattress you can afford, or want to protect your current one, a mattress protector is a smart investment: it'll extend the life of your mattress, keeping it in top condition for longer - and could help you sleep better too.

Mattress protectors act like fitted sheets. Not as thick as a mattress pad, they sit on top of your mattress and either slide around the sides, or are zipped and enclose the whole mattress for full protection - you'll find both options in our guide. 

The best mattress protectors are waterproof and breathable, with a high-tech fabric cover that wicks away moisture and helps keep you cool at night. Cheaper options tend to sacrifice the high-performance fabric to keep the cost down, but they still provide a valuable first line of defence for your mattress.

What's the best mattress protector?

We think the best mattress protector you can buy is the Purple Mattress Protector. Costing from $79, it's waterproof, stain resistant, and has an impressive 4.4 out of 5 reviews from users from over 6,000 user reviews.

Whatever you're looking for, though, we've got you covered. In this guide, we've found the best mattress protectors for all budgets, from luxury organic protectors to top-quality bargain options.

1. Purple Mattress Protector

The best mattress protector you can buy

Waterproof: Yes | Depth: Up to 15 inches | Colors: Grey, white, oat, purple, lilac, morning mist | Material: Polyester, spandex | Sizes: 7: Twin - split king | Trial: 30 days | Warranty: 10 years | RRP: $79-$158

100% waterproof
Very quiet - no rustling
Super easy to wash

Our pick for best mattress protector goes to Purple. The leading mattress maker has thrown its expertise into creating a five-sided, dual-layer protector that prevents spills from soaking into your mattress, while also adding an extra layer of comfort. There's a water-resistant inner layer that prevents any wetness from soaking through, and an absorbent outer layer that helps dissipate liquid so it doesn't create a puddle. 

Purple's mattress protector is also made from a stretchy, flexible fabric that's designed to not make a sound when you move, unlike some cheaper waterproof mattress protectors that can feel like you're sleeping on a crinkly trash bag.

The vast majority of users agree on the Purple website that the company's mattress protector is superb. It boasts an impressive 4.4 out of 5 stars from over 6,000 user reviews, with many praising how quiet and invisible it is, and saying that it fits well and stays in place over night. Many also comment that the waterproofing works very well - without blocking any of the benefits of their mattress. It's one of the most expensive options in our guide, but if you have the budget, it's one of the best mattress protectors out there.

2. White Company Luxury Quilted Mattress Protector

Non-allergenic mattress protector with plenty of padding

Waterproof: No | Depth: 12 inches | Material: 100% cotton | Sizes: 5: Toddler - king | Trial: N/A | Warranty: N/A | RRP: $44 - $79

All-cotton construction
Luxurious padded filling
Only 12 inches deep

Known for tasteful interior products and design, The White Company delivers the goods with its luxury quilted mattress protector. Sporting a diamond stitch design to keep the filling plump, it's 100% cotton and is also non-allergenic.

That padding is what sets this mattress protector apart from some others on this list. While it's not quite as plush as a mattress topper, it's certainly soft enough to add a nice amount of cushioning to your mattress and have you asleep in no time.

It's worth nothing that this protector can only cater for mattresses up to 12 inches deep though, so if you've got a quad-core hyper-foam behemoth of a bed, The White Company's protector might come up short. For the rest of us, though, this is a quality mattress protector that exudes luxury without the three-digit price tag.

3. Linenspa Cotton Terry Mattress Protector

Best cheap mattress protector

Waterproof: Yes | Depth: Up to 22 inches | Material: Polyester | Sizes: 7: Twin - Cal King | Trial: N/A | Warranty: 10 years | RRP: $17.99 - $24.99

Excellent value
Over 30,000 glowing reviews
Easy to clean
Some reports of leaks

Priced from $17.99, the Linenspa Cotton Terry mattress protector is a cheaper option for looking after your mattress. We especially like terry protectors because they're 'grippy', which means your sheet shouldn't end up sliding off the top. This is also a waterproof mattress protector, and it's machine washable too.

This isn't a high-end mattress protector, but Linenspa is definitely doing something right: it has over 34,000 reviews on Amazon, with an average rating of 4.4 out of 5. Most reviewers attest to the protector's waterproofness, with tales of dogs and infants doing their best to ruin mattresses, only to be thwarted by the Linenspa Cotton Terry mattress protector. However, a couple of buyers have commented that theirs has allowed liquids through - we're pretty convinced by the high average rating, but if you're specifically looking for a waterproof mattress protector this might not be the best choice.

best mattress protector: Avocado Organic Cotton

4. Avocado Organic Cotton Mattress Pad Protector

Best eco-friendly mattress protector - and a 100-night trial

Waterproof: No | Depth: 17 inches | Material: Organic cotton | Sizes: 6: Twin – Cal king | Trial: 100 nights | Warranty: 1 year | RRP: $199 - $299

Vegan and carbon negative
Luxuriously soft
Non toxic
Absorbent, not waterproof

Now for something totally different: the Avocado Organic Quilted Cotton mattress pad protector. Starting at just under $200, this is one of the highest-quality mattress protectors in the US. It's a protector-pad hybrid, so it's much more substantial and padded than the others on this list. But this organic cotton protector will also have you sleeping guilt free because it's made here in the US from all-organic materials, via carbon negative processes. 

The Avocado Organic Cotton mattress pad protector is a natural alternative to traditional plastic-based waterproof mattress protectors. That means it's absorbent, but not fully waterproof - so it'll keep your mattress safe from stains, skin oils, and perspiration, as well as moderate spillages. But it isn't the right choice for a kid's bed.

As you would expect for the price, this premium, cross-quilted mattress protector is machine washable. It comes with a huge 100-night trial, so you can test it from the comfort of your home, and there's a one year warranty too. If you're looking for an eco-friendly mattress protector, this is the best you can buy.

5. Utopia Bedding Waterproof Mattress Protector

Cheapest mattress protector

Waterproof: Yes | Depth: 15-17 inches | Material: Polyester/cotton blend | Sizes: 6: Twin – Cal King | RRP: $11.99 - $14.99

Excellent price
Useful elasticated design
Easily washable
Nothing fancy here

If you're on a shoestring budget but need a quality cheap mattress protector to help your bed live longer, this option from Utopia Bedding is a good one to consider. It's made from a poly-cotton blend, and claims to be totally waterproof without any of the rustling associated with cheaper products (its 4.5/5 average Amazon rating seems to back that up). Sometimes all you need is a budget mattress protector that will do the job without breaking the bank - and that's exactly what Utopia Bedding has provided here.

best mattress protector: Woolroom Deluxe Wool

6. Woolroom Deluxe Wool Mattress Protector

Best woollen mattress protector

Waterproof: | Depth: 18 inches | Material: Wool and organic cotton | Sizes: 6: Twin – Cal king | Trial: 30 nights | RRP: $198 - $330

All natural 
Temperature regulating 
Fully washable
Pretty pricey

If you're looking for a natural mattress protector that contains zero synthetic materials, the Woolroom Deluxe Wool mattress protector is a great alternative to the Avocado protector above. Naturally flame retardant and seriously comfortable - if its 4.9 out of 5 average user review rating is anything to go by - the wool construction is what sets this mattress protector apart. 

Don't be afraid that it'll make you overheat: the wool creates a naturally temperature-regulating layer. Plus it's naturally hypoallergenic, so it should be a good fit for anyone with allergies. But this mattress protector has a 30 night trial period, so you can test it for yourself. 

best mattress protector: American Baby Company Waterproof Fitted Crib

7. American Baby Company Waterproof Fitted Crib Mattress Protector

Best crib mattress protector

Depth: 9 inches | Material: Polyester | Sizes: 1: Crib | RRP: $11.50

Great value
Super soft for sensitive babies
Very easy to clean
Not a lot at this price

A crib mattress protector is essential for a baby or toddler – you don't want a new mattress ruined after a couple of nights. The American Baby Company crib mattress protector is a great option, offering a cheap, washable and comfortable way to protect a crib mattress.

With an impressive average rating of 4.6 out of 5 from almost 13,000 user reviews on Amazon, parents really like American Baby's mattress protector. There are even some bundle deals where you can save money if you buy two or more. All in all, this is a great way to protect your baby's bed long enough for them to outgrow it.

best mattress protector: Utopia Bedding Premium Bamboo

8. Utopia Bedding Premium Bamboo Mattress Protector

A popular bamboo mattress protector

Waterproof: Yes | Depth: 15 inches | Material: Bamboo | Sizes: 6: Twin – Cal king | RRP: $12.99 - $21.99

Fully waterproof
Cool and breathable
Can be delicate to wash

If you're looking for something a bit different, try the Utopia Bedding Premium Bamboo mattress protector. Fully waterproof - and with many users commenting that theirs is rustle-free - it's a great value way to protect your new or current mattress. Plus, with its bamboo construction, it's likely that this is a little more eco-friendly than most cotton rivals (although we can't say for sure).

The washing instructions state that you have to be pretty careful when cleaning the Utopia mattress protector, but with an average rating of 4.6 out of 5 on Amazon, it's clear that the vast majority of customers are pleased with their purchase.

best mattress protector: SafeRest Premium Hypoallergenic Waterproof Mattress Protector

9. SafeRest Premium Hypoallergenic Waterproof Mattress Protector

Best hypoallergenic mattress protector

Depth: 18 inches | Material: Cotton terry | Warranty: 10 years | Sizes: 6: Twin – Cal King | RRP: $24.95 - $34.95

Guaranteed non-allergenic
10 year warranty
Some say it crinkles

If you're an allergy sufferer, you'll need a mattress protector that's both hypoallergenic itself, and can also keep any dust and particles from escaping your mattress when you use it. The SafeRest hypoallergenic waterproof mattress protector is designed to do exactly that - and boasts an excellent 4.5 out of 5 rating on Amazon. Bear in mind that many of the lower ratings claim that this mattress protector isn't super silent. However, lots of positive reviews claim that it is - so you'll need to make up your own mind on this front.

best mattress protector: Lucid Premium Hypoallergenic Waterproof Mattress Protector

10. Lucid Premium Hypoallergenic Waterproof Mattress Protector

Best customizable mattress protector

Waterprood: Yes | Depth : 22 inches | Material: Polyester | Sizes: 6: Full – Cal King | RRP: $23.99 - $24.99

Choice of smooth or terry top
Can be crinkly

Finally, we've got another waterproof and hypoallergenic mattress protector, this time from the excellent Lucid. Here, you can choose between a soft terry or a classic smooth top, which is a nice option we don't often see.

Amazon reviews are stellar, with an average of 4.5/5, and tons of buyers claim that it's saved their mattresses from spills and accidents. However, just like the SafeRest above, some people do say that the protector can make a crinkling noise, and that it slightly changes the feel of the bed. For less than $25, though, the ratings speak for themselves and we think the Lucid mattress protector is well worth the money.

How thick should my mattress protector be?

Mattress protectors are quite different from mattress toppers, and their primary duty isn't necessarily to make your bed more comfortable – although many can certainly enhance your sleep experience. 

Protectors can range from anywhere between a few millimeters and an inch. On this list, most of the cheaper, more traditional toppers are probably around a quarter of an inch thick, while more luxurious, padded items are half an inch and beyond. 

However, bear in mind that mattress protectors aren't often made from memory foam, meaning any very thick protectors may flatten over time. 

If you want a thick layer of extra padding, it's worth investing in a quality mattress topper alongside a less expensive protector. The protector will keep your mattress safe from spills, while the topper will add a couple of inches of extra cush.

How do I choose the best mattress protector?

The best mattress protector for you might not be the best for someone else, and the first thing to consider when purchasing is what you actually need it to do.

Are you buying a protector for a toddler's bed, or perhaps you have a couple of dogs that can't help but leap on right after a muddy walk? In that case, you're probably going to want a waterproof protector.

If you're looking for a little more luxury and less intensive protection, a thicker protector like Woolroom's or Avocado's might be just what you need. Others protect from dust and bedbugs, while others still provide a a quick and easy way to remedy your night-time overheating. 

If you need to find anything else out, we'd certainly recommend reading user reviews on Amazon or the company's site, as these can be quite elucidating in terms of real users' experiences.

Are mattress protectors good for back and hip pain?

While some offer extra padding, if you're looking for substantial support you're going to want to upgrade your mattress with a mattress topper. They can provide extra depth and targeted support for those who suffer from aches and pains, or who have mattresses that are less than perfect.

What's the best way to care for my mattress protector?

Different mattress protectors have different care instructions, but the best way to look after it is to avoid putting it through extra stress in the first place.

However, almost all waterproof protectors are machine washable – they wouldn't be much good if they weren't – so if any accidents do occur you won't have to buy a new one.

Otherwise, most manufacturers will display care instructions on-site, so if you've got any special demands of your protector, your best bet is to check at the source.
