Best mattress protector 2024: waterproof, cooling and zipped covers compared

The best mattress protectors provide a barrier between you and your mattress, keeping your bed in tip top condition and helping extend its lifespan. After all, the best mattress deserves the best protection. With the right mattress protector, you can guard against spills, stains, allergens, and even bed bugs, so your mattress stays clean and dry.

When choosing a mattress protector, think carefully about what poses a risk to your bed. Families with not-yet potty trained kids can benefit from a waterproof mattress protector, which prevents liquids from sinking into the mattress core. Suffer from allergies? Hypoallergenic mattress protectors stop allergens like pollen, pet dander, and dust mites from settling into the interior of the bed. Hot sleeper? Cooling mattress protectors use cutting edge-temperature regulation to battle night sweats. And if you want to guard against bed bugs, opt for the all-round barrier of a zippered mattress encasement. 

Mattress protectors are key to keeping your bed clean, so our expert team has also considered practical factors such as ease of use and washing instructions in this round-up of the best mattress protectors. Read on to find our top mattress protector picks to suit every sleep style and budget.

Our top pick of the best mattress protectors is Purple. Here the leading mattress maker has thrown its expertise into creating a dual-layer mattress cover that safeguards against spills, dust mites and stains. A water-resistant inner layer prevents wetness from soaking through, while an absorbent outer layer dissipates liquid (including urine) so that it doesn't puddle.  

The five-sided Purple Mattress Protector covers everything apart from the underneath of your mattress and is designed to be stain-resistant, as well as machine washable.

You can buy it in seven different sizes, from twin to split king, and several different colors. We often see it pop up among the Purple mattress sales too, so you can usually save a few dollars on the price tag.

In terms of users reviews, the Purple Mattress Protector has a rating 4.4 out of 5 stars on Purple, and 4.6 out of 5 stars on Amazon. While there's lots of praise for the high levels of protection against spills and stains, a few users have said that despite Purple saying the fabric is quiet in use, theirs was noisy.

Purple's offering is one of the most expensive options in our guide, but if you want best mattress protector bar none, and one that's designed by a top-rated mattress in a box brand and that's covered with a 10-year warranty, here it is.

The Brooklyn Bedding Luxury Cooling mattress protector isn't just a premium protector, it's designed to help your mattress feel cooler to the touch. This is handy if you find your mattress to be a little on the warm side, though don't go expecting a miraculous cooling effect as you would get with a proper cooling mattress or topper.

Expensive in the smaller sizes

Not only is the Nectar Mattress Protector designed to safeguard your bed from spills, stains and allergens, it can also boost your in-bed comfort a little, putting it someway between a mattress cover and a thin mattress pad. 

The stretchy, non-slip design will fit mattresses up to 22 inches tall, and is easy to wash – simply machine wash and tumble dry on a low setting to freshen it up. Other perks include a five-year warranty, free shipping and returns, and a 50-night trial. 

No matter what size you choose, the waterproof Nectar Mattress Protector is a straight $99 – great if you’re after a Cal King, but it seems a tad unfair if you're just buying for a twin size bed. However, if you factor in the comfort on offer, then you might not mind paying a little extra for the smaller sizes when you can get a mattress cover with a padded cotton top for extra plushness.

Can't be ironed

If you're looking for an eco-friendly mattress protector to go with your organic mattress, try this 340gsm Utopia Bedding Premium Bamboo cover. It has a very slightly cushioned top, meaning it isn't as thick as a mattress pad and certainly not as plush as a proper bed topper, but it will add in a little extra comfort. 

Like other waterproof mattress covers in the guide, this one has a TPU to protect the top of the mattress - so the sides won't have the same waterproofing. It will help to protect against sweat stains, body oils and other moisture, and because bamboo is naturally breathable it won't collect heat either. 

If you prefer mattress protectors without thick elasticated bands, you'll love the design of the Utopia Bedding Premium Bamboo cover. That's because it opts for a Smooth Grip Skirt System, infused with elastic so that you can simply pull the borders of the pockets down to make it stretch over the mattress. 

Utopia Bedding Bamboo Mattress Protector: from $9.99 at Amazon

Budget mattress manufacturer Tuft & Needle has a good reputation when it comes to its mattresses and bedding, and the same levels of care can be found with its mattress protector. The Tuft & Needle is designed to be rustle-free and easy to care for – simply machine wash on a cold setting, then line dry or tumble dry with no heat. 

Waterproofing is taken care of via a polyurethane film, so you can rest a little easier knowing your mattress will be better protected from accidental spills. The Tuft & Needle mattress protector is easy to attach to your bed in the same way you would a fitted sheet, and is suitable for mattresses up to 14 inches deep. 

It’s worth keeping an eye out on the Tuft & Needle site for deals on this mattress protector, as it is slightly more expensive than some others. You do however, get free shipping, a two-year warranty and a generous risk-free 100-night trial.

Not the most durable material

This terry cotton mattress protector might feel soft, but it's tough when it comes to protecting your mattress against allergens, moisture, dust mites and bacteria. The SureGuard Mattress Protector is easy to clean in the washing machine and can be gently tumble-dried. That said, if you suffer from allergies then air-drying in the sun for at least four hours is recommended to properly kill dust mites. 

For the low price, there's plenty to like about the SureGuard Mattress Protector. It fits in the same way as a fitted sheet does, and can be used with most standard size mattresses. If you have an extra deep bed, this one is available in a range of depths up to 20". 

Sizes start from a mini crib size and because it’s designed to be noiseless, your little one shouldn’t be woken up by the sound of it rustling beneath them when they move around.

SureGuard Mattress Protector: was from $49.95 now $29.97 at Amazon
Confusingly, savings range from nothing to more than 30% off for the SureGuard Mattress Protector at Amazon. The queen size is discounted, reducing it to $44.97 (was $69.95). Still slightly pricey for a mattress protector, but good value for a premium 100% terry cotton product. Keep in mind that sometimes Amazon drops the MSRP, so even if there's no obvious discount, you might still be making a saving.
